后进程技术授予美国专利用于自动化支持技术

后进程技术, a manufacturer of post-printing systems for 3D printed parts, has been granted a U.S. patent for its Submersed Vortex Cavitation (SVC) technology.

该专利于8月11日发行,但最初于2016年6月提交,现在是后进程所拥有的50多种专利之一,其中包括硬件,软件和专有化学品。

丹尼尔·J·哈钦森(Daniel J. Hutchinson), inventor of SVC and Founder & CTO of后进程技术指出:“该专利的签发是确认我们多年来在后过程中从事的开创性工作。我们致力于创新尖端解决方案,这些解决方案将改变客户的工作流程并为行业4.0提供添加剂制造。”

累积的涡流空化

SVC是一个公司的四个后处理technologies, and focuses on support and resin removal. It works by completely immersing a 3D printed part in one of PostProcess’ proprietary detergents while rotating it in a mechanical drum with vortexes. At the same time, the system uses ultrasonic waves to create high-frequency pressure around the part, causing the weak support connections to break off while leaving the part intact.

SVC在公司的Centi,FORTI, 和黛咪支持和树脂去除机​​。该技术几乎与任何加性的聚合物部分兼容,专门针对FDM,Polyjet和SLA印刷组件的特殊洗涤剂。后进程已在全球各个国家提交了许多相应的专利,目前正在等待大规模批准。

Automated post-processing in 3D printing

The firm’s other support removal technology, Volumetric Velocity Dispersion, involves spraying a 3D printed part with a series of high velocity jet streams. The fluids flow bidirectionally to make contact with all areas of the part, and are pumped at a rate of 150 GPM.

PostProcess has also developed two surface finishing technologies specifically for 3D printing: Suspended Rotational Force and Thermal Atomized Fusillade. SRF utilizes an abrasive composite with rotational movement while TAF blasts a part with two perpendicular detergent jets to smooth its surface for aesthetics and functionality.

Just last month, UK-basedpost-processing specialistamtannounced that its化学蒸气平滑技术was now patent-protected in the UK. The patent covers all of the machines in the company’s PostPro3D series, a set designed to surface finish 3D printed parts made from thermoplastics such as polyamide, polyurethane, and polypropylene.

在其他地方,工程公司Renishawand 3D printing robotics specialistAdditive Automations已经合作了使用深度学习的自动化后处理。二人将开发算法来训练机器人臂以自动检测和删除金属3D印刷零件的支撑结构。Renishaw希望该项目将平均零件成本降低多达25%,从而使添加剂制造对于高吞吐量生产更可行。

第四届年度3D印刷行业奖将于2020年11月举行,我们需要奖杯。有机会赢得全新Craftbot Flow IDEX XL3D printer,enter the MyMiniFactory trophy design competition here。我们很乐意接受提交,直到2020年9月30日。
