瑞典航空航天初创公司杰森揭示了3D打印如何帮助建造去年推出的电动垂直起飞和降落飞机（EVTOL）。
设计用于模糊驾驶和飞行之间的界线杰森ONE本质上是一架小型私人飞机，任何有野心驶向天空（和备用$ 92,000）的人都可以购买和飞行。用一个Sinterit Lisa X，该公司不仅能够迭代原型，而且能够为EVTOL生产低体积的末端零件，否则通过铸造或成型来创造否则会很昂贵。
“We are using the printers for making prototypes, as we are trying different things. It is also nice to model something in CAD software, print it, and physically hold it in your hand and put it on the vehicle,” said Alec Bialek, Head of R&D at Jetson. “When 3D printing is so cheap, so accessible and so quick, it is actually a really great tool to sanity check your own designs.”
杰森（Jetson）的使命是“民主化”飞行
Based in Stockholm, Jetson is a company on a mission to change the way we travel. More specifically, the firm aims to ‘democratize flight’ via the launch of a personal electric aerial vehicle that “makes the skies available for everyone.”
自2018年建立首次概念验证以来，该初创企业一直在开发一种消费者友好的版本：jetson One。最终于2021年10月推出市场，这架小型飞机具有铝和碳纤维框架以及八个强大的电动机，并具有足够的功率，可以以高达63 mph的速度推动乘客。
While marketed as a “Formula One racing car for the sky,” the Jetson ONE is said to be easy to fly, taking just five minutes to learn how to operate. This is thanks to its intelligent flight computer in addition to its intuitive controls, with users’ left hand controlling altitude, and their right controlling direction. The new eVTOL is also said to be cheaper than its rivals, and it doesn’t require a pilot’s license to fly in the US.
尽管一次只能一次飞行20分钟，但飞行员有足够的时间有可能将自己陷入热水。认识到这一点，Jetson已将其新飞机安装在保护飞行员的赛车灵感安全牢房中。EVTOL还可以在需要时乘坐七个电动机飞行，并具有汽车功能，以确保民主化的飞行不会以安全为代价。
Flight-ready eVTOL 3D printing
正如您对飞行器的期望一样，Jetson One的设计对重量非常敏感，这意味着轻量级是其开发的关键。Jetson使用3D打印发现，它能够设计一些EVTOL的零件，以配备空心结构和非常狭窄的晶格图案，它们轻巧但足够强大，可以持续飞行。
Of the technologies out there the firm could’ve picked to develop these parts (as well as a number of prototypes), it chose Selective Laser Sintering (SLS) due to its speed, plus the strength and quality of the support-free structures it produces. As Bialek explains, Jetson initially started out with aSinterit Lisa Probefore eventually moving onto the faster, larger Lisa X system.
比亚莱克说：“当我们看着丽莎打印机线时，我们喜欢的两个主要内容是开源的材料，因此我们没有被锁定成一个品牌。”“另一件事是客户服务的表现如何。我们对丽莎Pro的所有支持感到非常满意。当我们寻找更大的打印机时，我们有一个很好的经验，没有抱怨，所以这对我们来说是一个非常轻松的升级。”
Jetson的工程师现在使用Lisa X到3D打印托架，该支架将电动机速度控制器和个人飞机的逆变器固定在适当的位置。Jetson One的仪表板以及其雷达和GPS天线的表圈装饰也使用3D打印制成，用于组装车辆的测试模板也是如此。
The first Jetson ONEs are set to be delivered between October and December 2023. While Jetson’s 2022 and 2023 production models have already sold out, it is still accepting orders for 2024 deliveries. Customers interested in ordering a Jetson ONE need to make a down payment of $22,000, before paying another $70,000 once it’s ready for delivery.
增材制造evtols绝不是规范，但是有证据表明，使用3D打印越来越多地制造了一些电动汽车和机载的车辆零件。实际上，Materialise’s Q3 2021 financialswere released last year, its CEO Fried Vancraen explained how its technologies have already been deployed in the production of theLift Aircraft电出租车。
More broadly, the technology continues to find applications within drone manufacturing as well. Earlier this year, for instance, it was revealed that theRoyal Air Force(RAF) in Britain is developing an aerialattack unit featuring 3D printed drones可以安装弹药并用来破坏战略目标。
