进入2022年下半年，3D印刷行业的航空应用激增。3D打印行业参观了Farnborough International Airshow, to see several of these AM for aerospace applications and we reported on others developed via government-backed defense contracts.
Elsewhere, market consolidation continued, while VC firms continued to pour hundreds of millions of dollars into additive manufacturing.
继续阅读7月的杰出发展，包括GE，GKN Aerospace，Am Ventures，Stratasys，Nano Dimension，Markforged，Digital Metal，AML3D，T＆R Bioofab，Ntopology，Ntopology，The Royal Air Force，等等。
航空AM在Farnborough起飞
Many of the year’s most innovative aerospace 3D printing applications were on show at Farnborough, and 3D Printing Industry was in attendance to cover all the latest developments.Skyrora,MELD,Boom Supersonic， 和GKN Aerospace提供了各自的3D打印项目的更新，后者揭示了它正在加强DED数据采集和控制系统。
7月，发布GE’s Q2 2022 financials还透露，通过向Delta Air Lines和Katar Airways等主要客户出售了200多个3D印刷的International Leap-1B发动机，从而提高了其收入。随着一年的发展，邀请3D印刷行业通过参观俄亥俄州辛辛那提的设施，以亲自了解GE的未来3D打印计划。
在巡回演出期间，据透露，GE的ATC将其金属池从三块扩展到6，包括Cobalt Chrome和Nickel Alloy 718，以及两对铝和钛合金。一些发展工作GE航空航天正在为US Armywas also covered, including its plans for the GE T901 engine, a propulsion system being designed to replace the Army’s current GE T700s.
In another defense application, it was announced that theRoyal Air Force was developing a drone attack unit由装有弹药的3D打印无人机组成，用于破坏战略目标。据说皇家空军将其重点放在创建可以更加紧迫的舰队中的舰队方面，据说取消了其先前的“蚊子”无人机建造计划。
Funding, consolidation and poison pills
July was a significant month in the 3D printing business world, with several major moves.Markforged获得的数字金属, in a deal that saw it expand into binder jetting for the first time.
This month, in a very different move,Stratasys做了毒药归档, afterNano Dimensionbought 12.12% of the firm. Filed with the US Securities and Exchange Commission (SEC), the company’s shareholder Rights Plan was essentially introduced as a way of discouraging Nano Dimension from attempting a hostile takeover.
在资金方面，AM Ventures closed its €100 million VC fundfor promising 3D printing start-ups, whileVulcanForms announced reaching funding of $355 million, the capital supports the opening of its first two digital production facilities, both of which are powered by its proprietary 100kW class laser powder bed fusion (LPBF) systems. One facility is focused on precision machining.
生成设计迈出了一步
已经是行业中领先的软件开发人员之一，nTopology通过升级到7月的拓扑优化平台，将事情进一步迈出了一步。除了发布nTopology’s third-generation latticing technology, it was revealed that the firm was developing several other design tools, such as field-driven lattice optimization capabilities and custom graph unit cells.
Trevor Laughlin, VP of Product at nTopology, said: “We are excited to release the latest generation of our lattice technology, which will continue to fundamentally change how engineers approach design for additive manufacturing. This new technology will enable industry-first advancements such as field-driven optimization, where the software automatically designs lattice structures for user-defined objectives and constraints. Ultimately, this will allow our customers to more effectively make use of the AM design space, resulting in innovative applications faster than ever before.”
July 2022: a big month for artificial skin
7月出现的最令人惊讶的趋势之一是宣布的人造皮肤3D打印项目数量众多。研究人员在Cornell University提出了biomaterial that can be 3D printed into tissues，意大利科学家团队开发了3D printed artificial skin for robots, designed to improve their sensing capabilities.
同样，在3D生物打印领域，T＆R BioFab申请了纸巾印刷技术that was said to have the potential to treat heart disease without requiring open surgery. As of July, the process had already proven capable of creating 100-micrometer cardiac spheroids that effectively regenerated damaged tissues upon transplantation.
A team at the加州大学伯克利分校, also unveiled a3D Cryoprinting technology这可以允许生存能力提高的组织。与其他生物打印的组织不同，这种组织可能太软以至于无法支撑自己的体重，科学家的技术会发现生物墨水冷冻和交联。这允许创建能够保留所需形状的细胞结构。
更难，更好，更快，更强壮……更大？
最后，长期以来，3D打印一直处于发展能够生产越来越大部分的大型系统的发展轨迹，这在7月也很明显。在这个月中AML3D3D printed an eight-tonne pressure vesselforExxonMobil. Utilizing its in-house Wire Arc Manufacturing (WAM) facilities, the firm reduced the part’s lead time from 12 months to 12 weeks.
The order, worth $190,000, further demonstrates 3D printing’s potential in oil and gas.
“Signing this deal with ExxonMobil is a further demonstration of delivery against our multi-phase growth strategy,” said Andrew Sales, MD of AML3D. “We have a major focus on building our capability and presence in the global oil and gas sector as an immediate value driver for the business, and this contract absolutely aligns with that objective.”
