Essentium和Lehvoss开发了FFF 3D打印的PEEK和HTN材料

Essentium Inc。, the Texas-based 3D printer manufacturer behindHigh Speed Extrusion(HSE)技术已宣布与化学和矿物质材料专家合作LEHVOSS Group开发用于增材制造的高性能材料。

The materials, comprising a line of PEEK and High-Temperature Nylon (HTN), were created specifically for production-level extrusion-based 3D printing processes. They are designed to meet the standards set by high-performance applications in aerospace, automotive, oil and gas, biomedical and electronic manufacturing industries.

这些材料在Essentium和Lehvoss之间进行了两年的合作研究和开发后发行,将它们各自的材料专业知识结合在一起。Lehvoss Group的3D印刷材料与营销总监Thomas Collet评论说:“与Essentium合作是我们工业客户的双赢。Essentium处于材料科学的最前沿,我们将共同创建更广泛的3D打印材料,以满足他们在最终用途中期望的性能标准。”

“这不仅速度和较低的上市时间the cost to produce the highest quality parts, it will also spur innovation for new additive manufacturing applications.”

High Speed Extrusion technology

Headquartered in College Station, east Texas, Essentium is the developer of HSE andFlashfuse添加剂制造技术。FlashFuse is a method of “FDM electric welding.” In this method, the electric charge of plasma is harnessed to improve 3D printed part strength across the Z axis.

另一方面,HSE是指Essentium的proprietary 3D printing platform它使用加热单元和喷嘴来适应3D打印时的温度从20-600度调整。HSE最初于2018年发布,打算解决传统FDM/FFF 3D打印机的速度和强度问题。2019年,Essentium展示了180-S 3D打印机将FlashFuse和HSE技术组合在一个系统中。

Essentium利用了open ecosystemfor its 3D printing technology, developed incollaboration with BASF and Materialise,它为客户提供了更大的控制和选择,软件和材料。Bart Van der Schueren, Materialise’ CTO explains that the partnership was formed in order to “promote a more open market model, which will fuel the adoption of 3D printing in the industrial field by offering users more control, more choice in materials and ultimately lower cost and higher volumes.”

The three partners have worked together to advance high-speed additive manufacturing, and as such, Essentium and BASF have also collaborated to为HSE平台开发材料。此外,在Formnext 2019上,Essentium引入了four new high-temperature filamentsfor the HSE platform including PEEK, HTN, HTN-CF25 and HTN-Z (ESD safe).

Developing robust materials for the factory floor

The LEHVOSS Group is a subsidiary of Lehmann&Voss&Co, a Hamburg-based chemical firm originally founded in 1894 as a trading company. LEHVOSS Group comprises a group of companies in the chemicals sector that develops, produces and markets chemical and mineral specialities for various clients. The company provides two product lines dedicated to 3D printing:luvosint和luvocom 3F,分别专用于SLS和FFF 3D打印技术。

Essentiumexplains that it partnered with LEHVOSS in response to the low performance of materials optimized but not specifically developed for 3D printing, which has thus inhibited the advancement of additive manufacturing, according to the firm. Therefore, the partnership aims to combine LEHVOSS’ extensive experience in thermoplastic high-performance compounds with Essentium’s knowledge in polymer and composite chemistry to develop production materials for use in a wide range of industry applications.

Essentiumhas thus launched a line of PEEK and HTN materials developed using LEHVOSS’ LUVOCOM 3F compounds. They are designed to provide easy printability, non-warping properties, heat and chemical resistance, and high mechanical strength in order to facilitate the production of quality end-parts for the factory floor. Certified for use on Essentium’s HSE 3D printing platform, the materials are geared towards applications in mechanical engineering, medical technology and automotive.

布兰登·斯威尼(Brandon Sweeney), Ph.D., Head of R&D for Materials and Co-founder, Essentium, concludes: “With LEHVOSS we have a true partner who shares our passion in applying material science innovation to accelerate industrial-scale additive manufacturing. We have already seen strong demand for our PEEK and HTN materials and look forward to developing new materials that give manufacturers the trust and confidence to shift from prototyping to full-scale production using 3D printing.”
