“When the year 2000 was upon us, books were written and people were philosophizing on what the greatest invention was of the last 1,000 years. And almost all people agreed that the greatest physical invention is the printing press.” – Ron Lasky, Ph.D., PE, Senior Technologist, “Design of Experiments (DOE) for SMT 101,” May 3, 2022
二手海德堡胶印四色印刷机是一台笨重的巨型机器，在扣除大量运费之前，其价格通常高达六位数。除了最初的现金支出外，新的拥有者还意识到，这些过去的遗物并不生产零部件：它们必须是定制的。印刷机是一项伟大的发明，但如果没有替换零件来维持运转，它就是一个巨大的镇纸。
Powder bed fusion (PBF) – first patented in 1990 by Carl Deckard at the University of Texas[1] – covers a range of additive manufacturing processes that all use a high-energy source (e.g., lasers) to sinter or melt together powder particles layer-by-layer resulting in a final solid part. Whether you need to recreate an OEM part for an offset printer, or you are a manufacturer in one of the critical PBF printed-parts markets today – satellites, rocket engines, drones, military and civilian aircraft, automotive, orthopedics, or medical (esp. dental) – PBF printers are capable of printing the most advanced metal parts, in a wide variety of build materials.
但是，这其中也有一个很大的问题：在标准的 PBF 工艺中，印刷部件与构建板融为一体，需要使用放电加工机 (EDM)、线锯或其他形式的切割工具进行机械分离。这样做既费时又费钱。
Indium Corporation® 很高兴推出全新的3D EZ Release™ 印刷板技术，该技术使分离步骤变得极其快速和简单；印刷部件可在数秒内而不是数小时内取出。
In this technology, Indium Corporation uses a low-melting point alloy in the top layer of the print plate. The laser-sintered printed part is bonded to this alloy layer, and thus separation can be achieved almost instantly by melting the alloy at a relatively low temperature of approximately 200°C – using nothing more than a hot plate or a standard oven. By removing the need for an EDM or other cutting saw:
- 简化了整个生产流程
- 降低了拆卸部件所需的占地面积
- 降低整个增材制造操作的拥有成本
- And, in many cases, Indium Corporation’s 3D EZ Release™ print plate can also eliminate the need for support structures and stand-offs.
Currently, the 3D EZ Release™ print plate is available in a ready-to-ship 3.5” x 3.5” size, compatible with the standard build plate for a GE Additive/Concept Laser/Mlab Cusing printer. However, our engineers can produce plates for other printers – contact us to discuss your specific needs.
无论您是在三维打印具有复杂几何形状的零件，还是在打印牙桥原型，如果工艺的最后步骤包括从结构板上机械分离材料、移除牺牲支撑结构、喷砂、机加工和打磨，那么3D EZ Release™ 打印板可以为您节省大量的时间、设备和资金。
