Automated post-printing system manufacturer后进程技术已经推出了Demi 4000，该公司最新的SLA树脂去除机。
With a processing tank measuring 890 x 890 x 635mm, the DEMI 4000 is PostProcess’ largest submersion system to date, and can hold up to 275 gallons (1040L) of resin removal detergent. As such, it’s designed to accommodate both large part sizes and multi-part builds, addressing the market demand for automated, hands-free finishing systems for high-volume SLA production.
Rich Caplow, VP of Product at PostProcess Technologies, states: “By driving industry-leading innovation that enables high-scale and high-volume additive production, we’re confirming our position as a pioneer in the next phase in the future of additive manufacturing.”
Submersed Vortex Cavitation technology
Operating on the company’s AUTOMAT3D software, the DEMI 4000 is the fourth resin removal system featuring the获得专利的二氧化涡气清（SVC）技术，以及DEMI，，，，FORTI，，，，andCenti。It utilizes ultrasonic waves, a vortex pump, and specially-formulated detergents to rotate fully-submersed SLA parts in the processing chamber, optimizing resin removal via a combination of chemical and mechanical energy.
通过AUTOMAT3D平台,用户也有交流cess to a range of pre-programmed, tried-and-tested recipes formulations for consistent part finishes. Alternatively, users can save their own custom recipes for a more focused experience. Driving the software is the company’s proprietary agitation algorithm, which closely controls the system’s energy, speed, direction, and temperature to avoid breakages and other failures.
The DEMI 4000
该新系统的构建旨在与后过程的整个专业洗涤剂组合完全兼容，该产品组合为各种树脂类型制定，包括陶瓷填充的树脂和高温树脂。据报道，该公司最近发布的PLM-403材料的寿命为6倍，这意味着较不频繁的储层更换和减少机器停机时间。
在Demi 4000内，后过程已将其安装到一个全新的可调式升降系统中，使用户能够一次处理多个高度和宽度的多个托盘。当然，该机器也完全封闭在不锈钢信封中，从而带来更安全，更清洁，更舒适的工作环境。该公司声称，Demi 4000的大型工艺会议厅是开发的，考虑了许多工业级SLA 3D打印机，包括雷电竞app下载3D Systems ProX 800，，，，RPS NEO800，，，，andStratasys V650。
Caplow补充说：“立体光刻是3D打印的最流行方法之一；通过将DEMI 4000添加到我们的投资组合中，SLA用户的所有构建尺寸和数量都可以使用软件智能解决方案完成完全的树脂去除，从而可以提供更大的自动化，并提高安全性和可持续性。”
尽管看起来似乎是次要的，但后处理通常与零件质量时的印刷阶段一样重要。最近的后过程announced a collaboration with大湖牙科技术这是北美最大的正畸实验室之一，可以自动化公司的粉末去除和表面精加工技术3D printed dental products。Specifically, the RADOR Surface Finishing process will be used to automate powder removal and surface finishing on SLS-printed parts.
在其他地方，后处理专家AMTwas recently granted a set of UK patents for its chemical vapor smoothing technology. The patents cover the portfolio ofPostpro3d系列中的机器，一组旨在表现出由PA，PP甚至某些玻璃填充衍生物等热塑性塑料制成的加性制造零件的系统。
