3D打印的机器人,征战机器人格斗场!

不知道大家对博茨大战(BattleBots)是否还有印象,这是一档美国的机器人格斗节目,于1999年-2002年,举办了5届。机器人之间的硬碰硬,还是让人看得非常过瘾的。只可惜后来停办了。 还好,去年博茨大战又重燃战火,并加入了飞行机器人这个项目,吸引了不少团队参与。 由于时间紧迫,参赛团队MBSRobotics使用了3D打印技术来制造他们的机器人——AfterByte。 为了使AfterByte在控制重量的同时,还具备良好的强度,MBS Robotics通过锤击测试了FDM(熔融沉积)和SLA(光固化)两种技术的打印件。最终,他们选择了SLA技术。 得益于3D打印,AfterByte不仅将总重量控制在10磅以内,内部还使用了具有通道的复杂部件,电线可以穿梭其中(可以起到保护作用)。拼接起来后,形成了一个传统制造技术不可能做出的设计。 AfterByte安装了Dyson真空马达,让其拥有了4Psi的力量。另外还安装了一个Dewalt冲击钻,可以120 ft/lb的力量进行攻击。 相信后面的博茨大战会有越来越多的机器人使用3D打印技术。   猜你喜欢: 《辐射4》的玩家太疯狂,可以买核子可乐了! 兵哥哥利用3D打印技术高效率低成本搞定进口设备维修 他是《守望先锋》玩家,又是3D打印爱好者,所以福利来了 3D打印应用新突破 美国医院借3D打印技术开发出用于抽脂手术 机器蜘蛛太空作业打造卫星 星球大战场面将变为现实   编辑:黑圆圈喵先生

【资讯动态】英国前教育部长倡议中小学配备3D打印机

英国前教育部长Kenneth Baker在2016年5月9日的《数字化革命》报告中,呼吁关注数字技术的教育问题。该报告预测,未来英国可能有1500万个工作岗位面临被自动化技术取代的风险,甚至包括目前相当紧缺的法律和会计行业。 Baker认为,那些可作为终身职业的工作都将消失。人工智能,机器人,3D打印技术和无人驾驶车辆将对各行业产生影响。 英国未来的人才需要具有在设计和计算方面的技能,并且需要有灵活性、创造力和进取心。而目前,这种思想在主流学校的核心课程中完全缺失。 为此,Baker呼吁,所有小学都应该拥有3D打印机和CAD软件。他认为这种增强创造力的建模设计的技能应当从小培养。 相信,不久的将来,不管是在国外,还是中国,3D打印都会成为一门面向各级学生和专业人士的系统化课程。 请点击以下链接,浏览英文原文: http://www.3ders.org/articles/20160509-all-primary-schools-should-have-3d-printers-lord-kenneth-baker.html   All primary schools should have 3D printers & design software, says former education secretary Lord Baker   In a report published today, former British education secretary Lord Kenneth Baker has said that every UK primary school should have a 3D printer. The demand forms part of an eight-point plan concerning education on digital technology and the prevention of future unemployment.   Lord Baker’s publication of “The Digital Revolution”, a report on the relationship between British education and future employment prospects for young people, comes shortly after the Bank of England predicted that 15 million UK jobs were under threat due to automation, in the form of driverless vehicles, robots, and more. According to Lord Baker, radical action is needed to ensure that the next generation of working adults is equipped to handle a new era in technology—the “fourth industrial revolution”, one of 3D printers, robots, and artificial intelligence.   Although Lord Baker believes that students should be introduced to 3D printing and design technology at a young age, he also singles out additive manufacturing technology as a threat to once-stable career options: “The economy is changing at an unprecedented pace,” he said. “Every day, jobs are being lost in professions we used to regard as careers for life. artificial intelligence, robots, 3D printing and driverless vehicles will impact on sectors as varied as the legal profession, transport and construction.”   As a response to changing technologies, the UK’s future workforce should develop technical expertise in areas such as design and computing, Lord Baker said in the report. These skills, however, should be combined with human traits such as flexibility, empathy, creativity and enterprise. Developing vocational skills at an early age would, naturally, encourage a divide between students pursuing these technical areas and those taking more classically academic subjects such as history, literature, and languages. This division is something which Lord Baker endorses: “We should not go back to a 19th Century diet of academic subjects for all,” he said. “We need 21st Century education for a 21st Century economy.”   Despite the importance of 3D printing and other emerging technologies, critics of Lord Baker—who was part of Margaret Thatcher’s notoriously brutal Conservative government during the 1980s—will be skeptical of the ex-minister’s proposal to effectively widen the gulf between an already alienated working class, for whom vocational subjects are traditionally advocated, and middle class, for whom “academic” subjects such as languages, humanities, and arts remain the norm.   The eight-point plan: Primary (elementary) schools should bring in experts to teach programming. All primary schools should have 3D printers and CAD software. Secondary (high) schools should offer technical subjects such as Computer Science in place of a foreign language GCSE, a qualification taken by students at the age of 16. The report suggests that the language of computing is now more valuable than a foreign language. The computer science GCSE should be taken by half of all 16-year-olds. Young apprenticeships at 14 should be reintroduced. Students should learn how businesses work. Some schools should offer a technical stream, including enterprise, health, and design, for students aged 14-18. Universities should provide part-time courses for apprentices, enabling them to get Foundation and Honors degrees.   Lord Baker is now chairman of the Edge Foundation, an organization which seeks to promote technical, vocational, and practical education for young people in the UK.   (摘自3D Printing Application)

【应用案例】创客用3D打印研发盲文显示器和键盘

世界卫生组织统计,全世界约有4000万到4500万盲人。然而,只有约10%的盲人能够识读盲文。造成这一结果的其中原因之一就是盲文阅读材料制作的成本偏高。与正常书籍不同,盲文书的内页上布满了一个个小凸点,它们还需要有较高的耐磨性。 硬件DIY改造社区Hackaday上一名叫Vinjay的创客与产品设计师Paul D’souza合作,经过3年的努力,他们的盲文显示器有了实质性的进展。 他们用微型震动电机代替了点阵式打印机的打印头。将小电机的运转转换为直线运动,以推动一个个组成盲文的凸点向上或向下移动。他们还用凸轮代替了震动电机的偏心锤,用制动器限制凸轮的连续旋转。 这里3D打印的部件包括了三个凸轮从动件,杠杆,弹簧,以及电机外壳。一部分部件与盲文的凸点连在一起。随着凸轮位置的变化,凸点也随着上下移动。 据悉,一个盲文单元模块包括了两个凸轮从动件,六个振动电机,一个外壳及一个盖板。多个模块的连接形成了一个完整的盲文展示。 他们的后续工作将集中于电子部件的研发,从而让电机以一种可控方式朝两个方向运动。   另外,Vijay还在研究一个盲文键盘的项目。这是一个能够与智能手机、平板电脑以及计算机一起使用的设备。目前,他已经通过Arduino微芯片完成了基本设计。该设备将配备12个主按键和4个方向钮以帮助盲人更方便的打字,并且通过振动电机提供触觉反馈。后期,这个键盘中还会被加入语音功能,这样盲人用户在敲击每个字符时就能够发出相应的声音。   需要浏览英文原文的朋友,请点击以下链接: http://www.3ders.org/articles/20160508-low-cost-3d-printed-braille-reader-aims-to-increase-literacy-rates-for-the-blind.html   There is a tremendous amount of good taking place in the 3D printing community these days. The cost of functional prosthetics has come down thanks in part to 3D printer enthusiasts inhabiting the eNABLE network and similar endeavors, for example. Then of course there are stories about the likes of Yogo the dog and his custom fitted 3D printed limb.   A new project has surfaced on hackaday about low-cost innovations that aim to spread the use of braille literacy for the blind. And if you consider the typical restrictions preventing further adoption of braille, these developments might have far reaching; even life-changing implications.   Braille literacy in the United States has been dropping for decades. 50 percent of legally blind school children in 1960 could read braille. A 2007 Annual Report has that number down to around 10 percent today. Furthermore, there is a direct positive correlation between literacy rates and higher employment rates to the visually impaired so a wider adoption rate is important. Unfortunately, financial restrictions associated current day braille readers is keeping a wider usership level down.   In development for 3 years now, hackaday user Vinjay and product designer Paul D’souza hope their Refreshable Braille Display and Braille Keyboard will turn that tide back around.   At the project's core, there are two devices. The display, which will allow the users easy access to braille literature, relies on a series of pico-motors to trigger the correct combination of cam followers that are directed through the 3D printed mechanism. It is a light-weight, quick to 3D print device. It is battery and Arduino micro powered by design but the exact electrical specs are not complete.   Also, thanks to a clever approach to design,  the braille reader can be 3D printed on most entry-level FDM 3D printers (with the design files available free to download) from the project’s creator dropbox). A couple of M8 screws is everything left to hold everything together.   The Brail Keyboard, on the other hand, has a primary objective to allow the visually impaired to communicate with the digital world. Conceptually allowing the use of braille shorthand, it is designed to further lower the potential barrier to learning braille. For now, this project remains in the very early stages of product development.   While both projects appear relatively basic from a mechanical perspective, there is a lot to learn and a long challenging road still lies ahead. But thankfully, after a call from the project's creator for suggestions on how to move things forward, the comments at the bottom of the hackaday article started piling up with informed opinions.   It looks like Vinjay is on the right track to bringing his Refreshable Braille Display to existence. And as things seem to be unfolding, it appears an interested following of project contributors is beginning to form. I'm sure we're in for some exciting developments in the months to come.   (摘自3D Printing Application)

The shoe was released in a limited batch of 96 pairs, selling out in 19 minutes.   In the footwear game, speed is everything—and not just on the running track. When Maryland-based sportswear company Under Armour released the first 3D printed training shoe for the consumer market back in March, both the sporting and tech worlds took note. A month later, New Balance released its own3D printed running shoe, the Zante Generate, but it was Under Armour who crossed the finish line first, and in some style.   In late April, Under Armour’s groundbreaking achievement was formally recognized by some highly respected voices in the design community. In Como, Italy, the Maryland company was awarded the A’ Footwear, Shoes and Boots Design Award, an international design accolade, for its “Architech” 3D printed shoe. A panel of 83 experts, including artists, stylists, and academics, reached the decision, with over a hundred other categories, such as furniture, lighting, and home appliance design, also evaluated.   The impressive 3D printed Architech shoe is the result of two years of hard work by design team Alan Guyan, John Acevedo, and Alan Toronjo. Over that busy period, the trio researched organic shapes and structures, which eventually inspired the 3D printed lattice design used in the shoe. This lattice structure purportedly provides a high level of dynamic stability for the wearer, and is most easily realized with the help of a 3D printer. No wonder the design is becoming popular in medical 3D printing and the aerospace industry. The 3D printed lattice structure makes up the entire midsole of the Architech, with the upper part of the design featuring a 3D “Auxetic" pattern which stretches to adapt to the shape of the foot.   Most importantly for Under Armour, punters have been sufficiently inspired by the 3D printed design to pay big money for the shoes: the $300 Architech was initially released in a limited batch of 96 pairs, which sold out in just 19 minutes on the company’s website. This positive response has led the company to continue down the 3D printing path: "We will continue to test and learn with this technology and customization," said Under Armour CEO Kevin Plank. "You can expect new 3D printed iterations later this year."   Six other entrants also received the A’ Design Award in the shoe category, with Tehran-based Atossa 3D printed footwear also flying the flag for additively manufactured shoes—theirs being more fashion-oriented than Under Armour’s sporting design. Under Armour, however, received the special honor of a “Platinum” award, granting Guyan, Acevedo, and Toronjo an invitation to a special black-tie awards ceremony in Italy.   To ensure a fair process, each member of the A’ Design Award panel submitted their vote anonymously. A jury member in the fashion category left the following anonymous feedback for the Under Armour 3D printed shoe: ”This design is truly amazing and appealing. For the first time in my life, I honestly [desire] and feel the urge to have a sports shoe. It is good to see innovation again blossoming at footwear design field.”   Receiving the design award provides good press for Under Armour, but business appears to be booming regardless: Under Armour stock surged on April 21 after the company posted impressive Q1 earnings which far surpassed analyst expectations. Footwear sales improved 64% year over year to $264 million, representing over a quarter of total sales.   (摘自3D Printer Company)

【应用案例】3D打印冲浪板尾鳍助力冲浪者驾驭风浪

当冲浪初学者第一次站上冲浪板时,脑子里想的第一件事肯定是如何保持平衡。但是,对于那些土生土长在澳大利亚新南威尔士州海岸边的冲浪高手来说,使用高性能的冲浪板才是他们最关心的。对于冲浪者来说,冲浪板上的尾鳍就像是足球鞋上的鞋钉,它可以提供给冲浪者更好的稳定性和掌控力。 为了帮助冲浪者们提升成绩,澳大利亚卧龙岗大学(UOW)的研究人员正在开发可以根据冲浪者偏好及海滩浪花特点量身定制的3D打印尾鳍。 冲浪板尾鳍的制作一般都会需要昂贵的开模,所以可供选择的尾鳍少之又少。为此,研究人员就是希望通过3D打印技术让定制尾鳍成为可能,这样专业冲浪选手和爱好者们就能够以低成本为自己的冲浪板安装最合适的尾鳍。 卧龙岗大学的研究人员用3D打印技术制造了一些尾鳍,并进行了测试。此外,冲浪板上还被特别安装了GPS跟踪设备,以收集浪数、速度,以及选手做转向、飞跃动作时的数据。 之后,他们会记录冲浪者的使用数据。目前,他们已经获得了超过1400个波浪和1100个转弯数据,通过这些数据,他们对尾鳍的外观进行了反复修改。 目前,该团队已经开始与一些冲浪板厂家进行了谈判,打算首先在卧龙岗地区推出这项定制服务,后续会在其他城市做进一步推广。 小伙伴们可以点击以下链接,浏览英文原文: http://www.3ders.org/articles/20160504-3d-printed-customized-surfboard-fins-will-allow-surfers-to-optimize-performance.html   3D printed customized surfboard fins will help surfers optimize performance and catch extra waves   Balance might be the only thing on your mind the first time you stand on a surfboard, but the experienced surfers that inhabit the coast of New South Wales in Australia are all thinking about equipment. About those little tweaks to board design and materials that can optimize their performance and help them catch those extra waves. It’s exactly why researchers from the University of Wollongong, which can be found right on the NSW coast, have now turned to 3D printing to quickly prototype and test numerous surfboard fin designs to facilitate more bespoke rides through the waves.   This is perhaps the most unusual 3D printing project to come out of the labs of the University of Wollongong (UOW), which is also known for its expertise in the field of 3D bioprinting. These 3D printed surfboard fins are actually part of the UOW’s Global Challenges program, which is aiming to use recently developed technologies to change lives everywhere. The project is headed by UOW Professor Marc in het Panhuis, who has previously worked on diverse 3D printing projects such as a 4D printed valve.   As the professor explains, their main goal is to break through design and manufacturing conventions for surfboards, and develop new shapes, sizes and materials that are more efficient and specifically tailored to suit the individual user and the waves they love. As part of that effort, they have also completely packed surfboards with sensors and GPS tracking devices to gather data on every wave, at every speed and during all turns and airs. “We want to come up with new, more efficient fins that can be bespokely designed for a particular surfer and a particular wave,” Professor in het Panhuis said.   This high-tech approach to surfing has already allowed them to closely track the performances of surfers at every skill level, which provides data for the development of new designs. So far, more than 1,400 waves and 1,100 turns have been tracked. All that data is being analyzed by computational fluid dynamics experts and other biomechanics specialists, who will study exactly how water flows around fins in certain conditions.   Through 3D printing, those findings are now being used to their full extent. The inclusion of 3D printing technology in the project was hardly surprising under the leadership of Professor in het Panhuis, who is the Associate Dean (International) of UOW’s Faculty of Science, Medicine and Health and an expert in material sciences. In particular, he sees it as a technology that brings flexibility to a field of rigid production standards and allows them to use all that gathered data efficiently. “Most current techniques involve molds that are expensive to make and hence, are harder to customize based on individual surfer’s needs. In contrast, 3D printing is a process that allows for rapid prototyping and rapid optimization of designs for individual surfers,” he says.   The Wollongong researchers have been experimenting with custom 3D printed fins for about a year now. As Professor in het Panhuis explained, it has enabled them to test a much broader range of designs and materials. “The difference lies in the fact that we can print fins very fast and make changes to the design extremely fast. On a daily cycle, we can go through three or four different designs of fins. A few hours later we have 3D printed fins coming out of our printer, and they are ready to work when they come off the printer bed,” he explained. “[Surf fins] go from flexible to fully stiff, and that’s one of the things we are investigating.”   Extensively tested in the lab and by actual surfers on the waves, numerous new insights into material and design performance have already been gained through these 3D printed fins. Professor in het Panhuis is therefore hopeful that they can bring 3D printing to the commercial surfing industry as well. “We’re already talking to a number of local surfboard manufacturers in who are interested. We hope to offer the customized service in Wollongong first and then eventually expand it,” he said.   According to Professor Geoff Spinks, who heads the Global Challenges’ Manufacturing Innovation department, this 3D printing project can revolutionize Australia’s domestic surfboard industry. “Australian surfboard makers are some of the best in the world, but they face strong competition from cheaper imports. To stay in business they must offer a high quality product that meets the customer needs,” he argued. “This project could take that engagement to a new level by individually tailoring the surfboard fins to the needs and abilities of the individual surfer.”   But ultimately, it’s about helping the average surfer as well. With the need for mass-customization more apparent than ever, Spinks believes 3D printing can really have an impact on the lives of everyday consumers. “When this project wraps up, we hope that surfboards can be designed completely for the individual, making it easier for people of all ages and sizes and abilities to have a go,” he concludes. Could surfing be that one niche that brings 3D printing to the mainstream?   (摘自3D Printing Application)

【资讯动态】谷歌CEO认为3D打印房屋将改变人们的生活

地球和人类未来一直是人们关注的热点。许多电影都描绘了反乌托邦的未来世界。同时,科研人员也将完全数字化集成列为未来发展的重点。近日,2016米尔肯国际会议在美国比佛利山庄举行。3500名有影响力的政客、科研人员和名流参加了本次会议。大家就地球和人类未来进行了探讨,谷歌母公司Alphabet的CEO Eric Schmidt向与会人员阐述了他认为可能会改变世界的六大项目。这些项目中,包括了将3D打印技术应用于建筑领域。 除了倍受关注的Eric Schmidt的演讲,本次会议中,美国前总统戈尔发表了关于气候变化的演讲,IBM总裁也展示了其公司的Watson软件平台。 3D打印技术被认为是建筑行业取得突破进展的关键性技术,它将产生深远的经济影响。   Alphabe的CEO告诉与会者,建筑业占据了整个经济的5%。当前的建筑工程在时间、材料和人力成本上的消耗都很大。一旦运用3D打印技术,施工时间会显著缩减,材料能够进行回收,工作效率也能获得显著提高。这种创新不但能极大地节约建筑成本,还能减少建筑业的碳排放量,起到保护环境的作用。 世界上第一座3D打印的别墅(上海盈创科技公司承建) 世界上最高的3D打印公寓楼(由上海盈创科技公司承建)   需要浏览英文原文的朋友,请点击以下链接: http://www.3ders.org/articles/20160503-3d-printed-buildings-can-improve-the-planet-says-googles-eric-schmidt.html   3D printed buildings can improve the planet, says Google's Eric Schmidt   The future of the earth and of mankind is a very topical right now, with movies depicting dystopian futures and technologists focusing on the the world's complete digital integration. All perspectives are currently being discussed at the prestigious Milken 2016 Global Conference in Beverly Hills, where more than 3,500 prominent politicians, technologists and celebrities have assembled. Among them is Eric Schmidt, the CEO of Google’s parent company Alphabet, who showcased the six ‘moonshot’ initiatives he believes will change the world in the long term. Among them is the adoption of 3D printing by the construction industry.   Schmidt’s presentation was one of the most anticipated events at the Milken 2016 Global Conference, but there was a lot more to see and do at the Beverly Hills event. For instance, former vice-president Al Gore talked about climate change, while IBM’s vice-president Guru Banavar showcased their Watson software platform as an assisting tool for CEOs. Other presentations focused on the Internet of Things, gene editing, the Mission to Mars, human connections in a digital world, and much more.   But Schmidt’s presentation was seen by many as one of the most impactful, as it focused on the entirety of human progress. “The best way to predict the future is to invent it,” he said, explaining why he believed just a few innovations could fundamentally change the future. Aside from 3D printed buildings, his so-called ‘moonshot initiatives’ are: a transition from meat-based diets to vegetable-based diets, the integration of virtual reality into society, opening up medical data through sensors and smartphones, the development of self-driving cars, and a tech-focused overhaul of education.   Many of these are staple innovations in futurist presentations; decreasing our reliance on livestock will, for example, decrease the strain on the environment. But it is very interesting that he chose to include 3D printing construction on that list. Of course 3D printing as a whole is often listed among breakthrough technologies - Gartner called it one of the ten strategic technology trends of 2016.But of all the possible 3D printing applications, Schmidt argued that 3D printed homes and buildings can have the biggest economic impact.   As the Alphabet CEO told listeners in Beverly Hills, construction represents five percent of the economy, and that entire segment can be made cheaper, more efficient and superior when it begins to integrate 3D printing. Right now, construction is time-consuming, energy-intensive, wasteful and costly, he argued. Through 3D printing, however, construction times could be decreased dramatically, and almost every structure could be made from recycled materials. What’s more, construction would be far more efficient if production took place on site. These innovations would not only decrease construction costs dramatically, but would also significantly decrease the construction industry’s carbon footprint. Construction-based 3D printing, it seems, should not be underestimated.   (摘自3D Printing Technology)

【资讯动态】世界首辆3D打印跑车获得北美技术创新奖

2016年5月,世界首辆3D打印跑车“Blade”的制造商 “Divergent 3D”获得 Frost & Sullivan 2016北美科技创新奖。他们的核心技术结合了3D打印技术,被认为是能够彻底改变汽车制造业的创新型技术。 3D创新技术的核心就是Node™的开发,这是一款3D打印的连接件,它可以将碳纤维管接入复杂的模块结构中,组成汽车的底盘。与传统汽车底盘相比,Node技术制造的底盘在重量上要轻5倍,而且更加坚固。 “我们的创新技术能够被Frost & Sullivan评委会认可,是一种莫大的荣幸。“Divergent 3D的创始人兼CEO Kevin Czinger说,“2016北美科技创新奖证明我们一直以来通过减少传统制造的污染和生产成本来颠覆汽车制造业,寻求可持续发展道路的努力是值得的!” 截止2050年,世界汽车制造量将达到40亿辆。为此,Divergent 3D的技术将会引起轰动。这种高质量的底盘系统,可以从根本上减轻车辆污染物排放,还能够承受极大的冲击力,提高燃料效率,为用户提供出色体验。 据悉,此前Divergent 3D就曾因为研发世界上第一辆3D打印超级跑车Blade而获得“年度最佳创新奖”的殊荣。它被认为是世界上最轻、最快的超级跑车之一。   3D Node技术对汽车制造商来说,有很大的吸引力,预计未来2到5年内,这项技术就会在欧洲、亚洲和美国的汽车制造商中广泛应用。   请点击以下链接,浏览英文原文: http://www.3ders.org/articles/20160504-worlds-first-3d-printed-supercar-wins-2016-north-american-technology-innovation-award.html   World's first 3D printed supercar wins 2016 North American Technology Innovation Award   In another notable moment for 3D printing technologies, consulting and market research firm Frost & Sullivan has named Divergent 3D, the manufacturing company responsible for Blade, the world’s first 3D printed modular supercar, the winner of the 2016 North American Technology Innovation Award. The award was given after a thorough analysis of structural manufacturing in the automotive industry.   Divergent 3D, which we wrote about last year, has developed an innovative approach to automotive chassis manufacturing which involves a proprietary metal 3D printing process. The process, which utilizes direct metal laser sintering (DMLS), has resulted in a more efficient, lightweight, and sustainable chassis design, effectively allowing for a lower emission, and optimized supercar.   The key to the company’s innovation has been the development of the Node™, a 3D printed alloy joint which is capable of connecting carbon fiber tubing into modular structures, making up the car’s chassis. According to Frost & Sullivan, this novel 3D printed approach to chassis manufacturing actually uses less energy and raw materials than traditionally used processes, and makes the assembly of the chassis easier for manufacturers as it effectively eliminates the need for metal tooling and sampling equipment. As the consulting firm stated about the potentials of the Node technology, “The 3D Node™ technology has broad appeal and is expected to be used by automakers in Europe, Asia, and the United States in the next two to five years, and has the potential to set a benchmark through its installation in vehicles of all types."   Not only useful for supercars however, Divergent 3D’s technology can reportedly also be adapted to any vehicle type, making the company’s approach a potentially revolutionary one for the automotive manufacturing industry. Doraiswamy Bharath Sunderraj, a Frost & Sullivan Research Analyst, explains, “Divergent 3D's chassis system can be applied to any vehicle type, from sports cars to pickup trucks. Because the chassis system is lightweight and reduces the overall weight of the vehicle, it can slash the total lifecycle emissions of a passenger vehicle in half and diminish the capital cost of designing and manufacturing vehicles by 10 times.”   Considering the impressive advances made possible by Divergent 3D’s proprietary 3D printing technology, it is not surprising that they received Frost & Sullivan’s 2016 North American Technology Award. Every year, the award is presented to a company that has demonstrated a novel and innovative use of new technologies, which is not only relevant to the industry in question, but presents new products and applications that are forward thinking and high performance.   Founder and CEO of Divergent 3D, Kevin Czinger says, ”It is an honor to be recognized by Frost & Sullivan for our innovation that stands to transform the automobile industry. This 2016 North American Technology Innovation Award is validation of our ongoing efforts to revolutionize car manufacturing by reducing the pollution and production costs of traditional manufacturing, resulting in a sustainable path forward for the car industry.”   Frost & Sullivan’s judges for the 2016 North American Technology Award looked at several factors when considering Divergent 3D against its competitors, including technology attributes and future business value. Among its other high points, it was the company’s Node system that truly impressed the judges, who gave the company a 9/10 and a 9.5/10 for both the aforementioned categories.   Having received Frost & Sullivan’s prestigious title, Divergent 3D is rising as a viable manufacturer of 3D printed vehicles, and perhaps in the next few years we will see their innovative and more efficient 3D printed chassis system implemented in car making on a large scale, making the automotive industry as a whole more affordable and green.   (摘自3D Printing Application)

【应用案例】制作高品质手办,手工制作与3D打印谁更牛?

手办也称人形,指的是现代的收藏性人物模型,也可能指汽车、建筑物、视频、植物、昆虫、古生物或空想事物的模型。真正意义上的手办指的是表现原型师个性的,没有涂装的模型套件。但现在在中国大陆很多玩家都习惯了手办泛指到所有人形作品的叫法。 “手办”是“首办”同音衍生出的译名。“首办”是玩具厂在未开发新工模前,会预先请师傅“起办”,师傅造出来的“原型” 行内称之为“首办”。即“首先/初型”的含意 ,可以手作亦可以用车床/铣床制作(CNC)。 最近有大神分享了使用3D打印制作手办的过程。小编不禁好奇,和传统手工制作比较,两者谁更牛逼呢?于是小编找来了两大工艺的制作过程,大家一起来比较下吧。(3D打印与CNC工艺对比可以点击这里查看哦!) 手工工艺: 原图 需要的工具 卡钳 意大利面加工机 绘制蓝图 使用螺纹杆做主要支持 将螺纹杆固定住 用铁丝制作骨架造型 混合粘土 从中间慢慢开始填充 在纸板上剪出一个大致的轮廓,把握大小 主体大致完成 制作出纹理 做出四肢 基本完工   3D打印制作 首先是在3D软件中建模   将3D模型分割成多个部件,便于打印 光固化打印 去掉支撑 细节非常到位 用胶水将部件拼接起来,再喷补上土 补上土后,可以对细节进行加工处理 完工 手工制作虽然在精度方面比3D打印和CNC工艺略差一些,花费的时间也比较久,但胜在神韵,作品更具灵性。 3D打印不仅具有非常高的精度,在后处理方面也具有非常大的空间,能赋予作品神韵和灵性,而且非常节省时间。

【工具指导】史上最全STL格式转换问题大全

 3D打印过程中的一项重要步骤就是将3D设计文件转换为STL格式的3D模型文件。一个STL文件基本上是用众多的三角形来定义一个3D模型,因此包含了所有这些三角形的法线与顶点的XYZ坐标的完整列表。如果这个文件中出现太多的三角形定义,那么这个文件就会过大,并被称为“坏”文件。这个时候,一些老生常谈就显得相当重要了。今天,就为大家分享一些转STL文件骤中的注意事项,以及STL格式的转换过程中可能出现的问题。 一、生成STL格式的模型文件需注意的事项 1、共顶点规则 每相邻的两个三角形平面必须且只能共享两个顶点。一个三角形平面的顶点不能落在相邻的任何一个小三角形平面的边上。 2、取向规则 对于每一个小三角形平面,其法向量必须向外,3个顶点连成的矢量方向按照逆时针方向的顺序确定(右手法则)。而且,对于相邻的小三角形平面,不能出现取向矛盾。 3、取值规则 每个小三角形平面的顶点坐标值必须是正值,零和负值都会导致失败。 4、充满规则 在三维模型的所有表面上,必须布满小三角形面片,不得有任何遗漏。 5、欧拉公式 STL文件中顶点数V、边数E、面片数F之间必须符合欧拉公式。    二、STL格式转换过程中可能出现的缺陷 1、存在缝隙,即三角形面片的丢失 对于大曲率的曲面相交部分,三角化时就会产生这种错误。在显示的STL格式模型上,会有错误的裂缝或孔洞(其中无三角形),违反了充满规则。此时,应在这些裂缝或孔沿处增补若干小三角形面片。 2、畸变,即三角形面片的所有边都共线 这种缺陷通常发生在从三维实体到STL文件的转换算法上。由于采用在其相交线处向不同实体产生三角形面片,就会导致相交线处的三角形面片的畸变。 3、三角形面片的重叠 面片的重叠主要是由于在三角化面片时数值的圆整误差所产生的。三角形的顶点在3D空间中是以浮点数表示的,而不是整数。如果圆整误差范围较大,就会导致面片的重叠。 4、歧义的拓朴关系 按照共顶点规则,在任一边上,仅存在两个三角形共边。若存在两个以上的三角形共此边,就产生了歧义的拓朴关系。这些问题可能发生在三角化具有尖角的平面、不同实体的相交部分或生成STL文件时控制参数出现误差。 因为这些缺陷,在打印过程中我们必须事先对STL文件数据的有效性进行检查,否则,具有缺陷的STL文件会导致快速成形系统加工时的许多问题,如原型的几何失真等,严重时会还会出现死机。

【工具指导】如何将废弃物料重新利用?

开发板和3D打印技术可谓是现代创客的两大法宝,这两者的出现极大地拉低了创客的入门门槛。到现在,创客文化已经在开始逐渐变成大众文化的一部分了。 对于3D打印,目前常用的材料通常是塑料或树脂等易塑的材料(当然,不同的应用领域还有其它不同种类的材料,如石膏、玻璃和金属,甚至还有用食物来作为打印原材料的)。 塑料大受欢迎的原因很简单,塑料成型的速度较快,加热温度低也更为安全,更重要的是价格低廉。但如果你是一个经常使用3d打印机制作模型和器材的创客或设计师,不管是因为设计失误还是打印出错,你多半会遇到放弃已经打印好的作品的时候——然而就这么丢掉好几个小时才打印好的组件似乎有点可惜,而且还不够环保。 为了解决这一难题,一家名为Felfil的初创公司近日在众筹平台Kickstarter上上线了一个开源的拉丝器Felfil Evo。通过使用这种拉丝器,你可以很容易就将塑料原料拉成3D打印机所需要的丝状,这样你就可以回收利用以前打印的但不再有用的组件了! 而该拉丝器不仅仅是回收利用塑料丝那么简单,你还可以通过直接购买塑料原料来自己加工塑料丝;据Feltil介绍,这可比散买塑料丝便宜,而且你还可以根据原料搭配来配置自己所需的塑料丝颜色。 据Felfil介绍,Felfil Evo在工作过程中会首先将塑料加热到300摄氏度,并拉出直径在1.75mm、2.85mm或3mm的塑料丝。目前已支持PLA和ABS两种塑料材料。 拉丝中…… ▲Felfil Evo加工的塑料丝 据Felfil介绍,该团队的这款产品的设计已经持续很长时间,最终他们终于能让拉出的塑料丝保持在正确的直径上并且足够均匀了。 事实上,Felfil在Kickstarter上预售的是一个组装套件,其核心控制器是Arduino开发板,用户购买后需要将其自行组装成拉丝器。如果你对这个产品感兴趣,现在就可以在其Kickstarter页面上进行预订,最低170欧元(约1195元人民币)就能在今年5月份获得一个最基本的套件,而要获得全部套件,则至少需要300欧元(约2107元人民币)。 a ▲套件

【工具指导】荷兰3D打印厂商推出最新ColorFabb_HT线材

日前,荷兰知名3D打印线材厂商ColorFabb推出了他们的最新3D打印耗材:ColorFabb_HT。该款产品是基于Amphora HT5300 3D聚合物材料制造,具有无刺激性气味,无苯乙烯,耐久、耐高温、稳定性高的特点,非常适合那些对3D打印质量较高的用户使用。 Amphora HT5300材料非常适合制造优质线材,此外这种材质也非常适用于具有多个部件组成,精准度要求相对较低的3D打印对象。最重要的是,这种线材能够承受高达100摄氏度的高温,可以作为原型和测试产品的理想材料。 这款线材预计于2016年3月21日正式发售,将有:透明、白、浅灰、深灰、黑色5种颜色选择。以下是通过这款线材3D打印的样品图片: 感兴趣的朋友们也可以登录Nervous System的官方微博,浏览更详细的信息。   ColorFabb_HT filament revealed, perfect for durable and temperature resistant 3D prints The web is filled with fantastic and inspiring 3D printing projects that illustrate just how big the hobby has gotten. The only downside is that the tried-and-tested ABS and PLA filaments don’t always cut it for research projects and practical prototyping. While results tend to look good, they don’t always have the right toughness or strength to do whatever they need to do. When that happens, the best thing is to try less conventional filaments, and as it happens renowned Dutch filament provider colorFabb has just unveiled the latest edition to their excellent range: colorFabb_HT, a clean material perfect for practical 3D printing solutions due to its high strength, superior durability and stability, toughness and excellent temperature resistance. Dutch manufacturer colorFabb is, of course, known for their excellent 3D printing supplies. Founded as a branch of Helian Polymers, a sister company of Peter Holland, a few years ago, they quickly became the provider of a number of excellent and sometimes unusual filaments. While some of their other materials are largely attractive for aesthetic reasons, its excellent qualities are colorFabb_HT’s main selling point. It is made from Eastman’s Amphora™  HT5300 3D polymer, which is styrene and BPA free, low-odor and particularly suited for parts exposed to unusual circumstances. It features an advanced overhang ability too, **** it perfect for practical parts. “Demonstrating superior dimensional stability, HT5300 allows for 3D printing to exacting dimensions, which is especially important for products with tight tolerances and multi-component parts. Moreover, with its outstanding toughness and chemical resistance, Amphora HT5300 is ideal for prototyping and testing products,” the manufacturers proudly say. The impressive drill holder (seen above) really says it all when it comes to durability. Perhaps most impressive is it high heat resistance, with 3D printed colorFabb_HT parts being capable of withstanding heat up to 100 degrees Celsius. “That means your co-polyester creations can finally withstand heat without deforming. This opens up new areas in which 3D printed applications can be successfully applied,” they say. This is illustrated with 3D printed toy engine parts, made by a user named Dennis. “By using colorFabb_HT, Dennis is able to experiment with custom shaped inlet manifolds to improve the performance of this Mini track car. The fact that he can now test these parts on a running engine means a lot in his design process,” they say. If you’re interested in this excellent filament, it is set to go on sale in three weeks, on March 21 – both through their web shop and their international resellers. Pre-orders for colorFabb_HT will begin before that time. The functional filament will be available in five colors: clear, white, light gray, dark gray and black. You can also catch colorFabb at RapidPro 2016 this week. At the convention in Eindhoven, the Netherlands, they will showcase a variety of their filaments, so you can check out the results in person.

【应用案例】3D打印,让知识不再停留于纸上

任何上过高中生物课的人可能都记得自己花费好几个小时去学习让人眼花缭乱的人体解剖图的经历。试想一下,如果这个解剖图变成了实实在在的3D打印模型,那么学生们学习人体结构和各种内部器官就会变得容易很多。 为了使自己的生物课变得更有吸引力,一位国外的生物教师聘请工业设计师Jordan Pelovitz为其设计和3D打印了一个逼真的人体解剖模型,让学生们可以与之互动,并从中学习。 教师希望Pelovitz设计出一个能够表现出各种人体解剖系统如何互相关联的模型。 最终Pelovitz打印了一个完全3D打印的人体“拼板”,包括了从关节到各种骨骼、肌肉细胞的所有人体器官与组织。 Pelovitz介绍说,“我的任务是建造两个器官系统——消化系统模型和骨骼系统的一部分。” Pelovitz设计并3D打印了所有的大肠、小肠、肝、胃。而这些3D打印器官还需要能够装到一个假人模型里。3D打印的骨骼系统则是人体腿部的部分,其中包括了3D打印的股骨模型。 除了3D打印这些主要器官或骨头之外,Pelovtiz制作的3D打印解剖模型还展示了不同的平滑肌细胞和平滑肌组织之间的区别,以及骨组织和成骨细胞之间的差异。 无独有偶,还有教师利用3D打印技术来进行青蛙解剖的教学。学生可以下载和在教室里进行3D打印。在无需解剖真的青蛙而感到恶心的情况下,就能教学生们基本的解剖学原理了。 除了解剖教学,地理教学也可以通过3D打印,将“平面”地形变成“立体”,让学生们一眼就能明白怎么回事。 3D技术正在逐渐普及,就像当年的电脑一样。学校可以开设3D打印课程,让学生们能够充分发挥自己的创意,制作自己喜欢的小玩意,在玩得过程中学习。 另外,历史、生物、地理、化学、物理等课程的一些原理图、模型,都可以打印出来,比较直观地让学生了解。 DNA分子结构 齿轮 减速箱
