The finalists for the 2019 3D printingPurmundus挑战have been unveiled.Held by German rapid prototyping companyCIRP GMBH, the annualPurmundus挑战邀请来自世界各地的设计师和工程师参加基于主题的3D打印设计竞赛。今年的主题是“超越3D打印”，并在3D印刷行业的自豪支持下返回了第七年。
总计38名决赛选手已选择，现在将前往Formnext 2019从2019年11月19日至22日，将宣布获奖者。产品思想包括来自5大洲的18个不同国家的条目，涵盖了医学领域，4D印刷，仿生学，流动性，生活方式，家具，艺术等的前瞻性概念。
超越3D打印
The purmundus challenge has been running since 2012, and aims to showcase ground-breaking 3D and 4D printing ideas in the field of product design. With this year’s “Beyond 3D printing” theme, the purmundus organizers describe the 38 finalists as demonstrating the “enormous potential of additive manufacturing” with smart innovations in various different markets.
引人注目的参与者包括离子音响系统, a 3D printed commercial audio set made from sand launched in February 2019. It is designed by深度，捷克设计工作室专门从事音频产品。它由两个被动卫星扬声器和一名活跃的亚宣传炮组成，是使用粘合剂喷射技术开发的。3D打印能够创建具有良好声学品质的独特扬声器设计。
Sandvik，瑞典工程集团（Swedish Engineering Group）有两个有趣的意见，这些提交已进入最后的38个条目。第一个产品是公司声称是world’s first smash-proof 3D printed guitar。Consisting of a 3D printed titanium body, and a neck supported by Sandvik’s hyper-duplex steel technology, the instrument was strong enough to resist guitar player Yngwie Malmsteen’s attempts at breaking it.
Sandvik的另一个条目是对first ever 3D printed diamond composite，它在RAPID + TCT2019. Using stereolithography (SLA), Sandvik researchers implemented a slurry consisting of diamond powder and polymer to 3D print the diamond composite.
UrbanAlps，一家瑞士高安全性公司隐身钥匙。这是一个完全定制的机械键，它的圆柱形覆盖了隐藏解锁代码。这意味着无法拍摄或扫描钥匙的焦点（与解锁机制相关）。
机舱和航空电子航空制造商Diehl Aviationis also among the 38 finalists with its3D打印的窗帘舒适标头that it developed for Airbus’ A350 XWB jet airliner. It was produced using FDM technology, and is reportedly the largest 3D printed part to be produced for passenger aircrafts.
Winners of the 2018 purmundus challenge
Three winners will be selected from the 38 finalists, with awards worth a total of €30,000 divided between them. In addition to the first three places, there will also be a “special mention” and an “innovation prize.” A prize for the “people’s choice,” voted for by visitors to Formnext 2019 will be handed out, as well as a new prize category called “simulation driven design by Altair.”
Permundus 2018获奖者was Ricardo Simian of3D Music Instruments，他们提交了SLS印刷的Cornetti。亚军包括制作阿迪达斯砂鞋的工业设计师Aarish Netarwala，以及来自Christoph Kiener博士和Manuel Biedermann。Siemens AGfor their bionic fuel burner.
2019年Purmundus挑战赛的三位获奖者将由国际专业人士的陪审团选择，基于3D印刷产品在使用，经济和美学方面以及设计本身和创新方面的好处。奖项将于2019年11月21日下午5:00在Formnext博览会11.1-D29厅的AM4U地区颁发。如果您不参加formnext，则可以通过Formnext Facebook门户通过直播来参加仪式。
