Canadian 3D printer manufacturerRapidiahas announced plans to bring its “innovative metal extrusion technology” to the European market.
Rapidia的两部分3D打印机和炉系统可以将独特的水基金属糊剂逐层沉积到复杂的零件中，在烧结之前不需要删除。在其快速制造过程背后的紧凑型机器后，欧洲的物理首次亮相Formnext，该公司现在计划在2023年第一季度将其推向市场。
Rapidia’s metal extrusion technology
Since it was established in 2016, Rapidia has focused on developing a metal 3D printing technology that’s faster and more accessible than existing offerings, but still yields high quality parts. What it has come up with is a process whereby a paste-like feedstock, made up of metal powder, water and a tiny amount of binder, is deposited onto a heated bed, on which its water content is evaporated away.
与许多系统的竞争对手相比，依赖于由聚合物绑定的金属粉末的竞争对手，它会产生不需要脱颖而出的绿色零件。这不仅使Rapidia的流程更快，而且可以确保其用户不必投资于大型，昂贵的脱颖而出的设备，从而使其相对“办公室友好”。
使用水性糊状物还提供了设计优势。由这样的原料制成的零件可以合并为更合并的复杂构建。因此，该技术为用户创造了将零件打印成部分的机会，可以将零件弄湿并彼此堆叠成完整的构建。
Thus far, the company has brought this process to market via the launch of both a proprietary 3D printer and a furnace, designed to offer partial pressure sintering in argon and yield parts with excellent metallurgy. Together, these machines ultimately enable the printing and direct sintering of components, through a process that in many cases takes just 16-24 hours from start-to-finish.
将Rapidia 3D打印带到欧洲
Rapidia’s efforts to commercialize its technology initially saw it partner withExoneduring 2020, in a collaboration which yielded theMetal Designlab and X1F furnace。Though slightly bigger than Rapidia’s original 3D printer, the Metal Designlab remained small enough to target the office-friendly space, while providing users with another means of adopting its two-stage additive manufacturing process.
交易签署后，它还包括一项规定，Exone将首先拒绝以后对基于温哥华的合作伙伴的收购。但是，跟随Desktop Metal’s acquisition of ExOne, the two firms have now parted company and Rapidia has returned to the independent distribution of its hardware and feedstock.
On the research front, Rapidia says its technology’s open nature continues to allow for the development of new sintering cycles and specialized pastes, and in order to capitalize on the interest this is helping generate, it has given its portfolio a physical debut at Formnext, ahead of its first shipments to European clients in Q1 2023.
