染色launches VaporFuse Surfacing giving gloss to 3D printed parts

Recently, German post-production solutions provider染色推出了它蒸气表面(VFS)3D打印零件的技术。

VPS技术适用于完成激光烧结(LS)和HP多喷射融合(MJF)工艺的最终产品,VPS技术是与注射成型零件质量相媲美的3D打印的一步。

PolyShot vs. VaporFuse

随着VP的添加,DyeMansion现在为客户提供了两种表面饰面。

PolyShot Surfacing (PSS) is a mechanical finishing process that gives parts a matte surface, and enables the addition of vibrant colors, now covering the entireRAL spectrum

然而,使用VPS,DyeMansion将光滑的饰面引入了3D印刷品 - 由于其粉末状的原料,通常使用LS和MJF制成的物体的特征。

Achieving a smooth surface finish

顾名思义,DyeMansion的VPS技术使用行业安全的溶剂来处理3D印刷零件的表面。该溶剂将颗粒溶解在3D印刷零件的表面上。正如Dyemansion的研发化学家Alena Folger博士解释的那样,这给出了“聚合物链在表面上具有足够高的迁移率和重新排列。”

在此过程中,表面积和能量会减少,同时平滑这些颗粒。Folger博士补充说,最终结果是“ 3D打印的零件,表面闭合,光滑”。这些零件具有较高的刮擦性,并且完全是驱蚊剂,在医疗部门尤其需要的特征以及时尚和运动器材等消费区。

3D打印的未来:最终用途应用程序

Integrated within DyeMansion’s打印到产品的工作流程, VPS is compatible with a wide range of materials, from tough PA12 (as with PSS) to TPU and other soft materials.

在关闭Dyemansion的首席执行官兼联合创始人Felix Ewald时,我们在DyeMansion中认为,增材制造的未来[…]的未来更多地是关于最终最终用途零件和应用的适当饰面。”雷电竞充值

In addition to EOS and HP, the company works with 3D Systems, Prodways, Farsoon andvoxeljet High Speed Sintering(HSS)技术。

埃瓦尔德补充说:“与打印机制造商的合作表明,染色体正越来越成为这些应用程序的平台,”

“[…] we work constantly on expanding our portfolio with new systems and technologies.”

染色is currently for more beta customers to put VPS to the test and can becontactedhere.
