后期过程声称VAD技术已经成功地与大型工业客户一起运营，在生产环境中处理数百个SLS粉末蛋糕和数千个零件。
后期过程is a US-based global provider of intelligent post-printing solutions for additive manufacturing, andEOS是总部位于德国的工业3D打印制造解决方案提供商。为了为EOS消费者提供完全自动化和可持续的缩减解决方案，两家公司宣布了合作联盟。与后期过程Variable Acoustic Displacement™ (VAD) technology, 3D printed parts’ gross depowdering is automated, completing the EOS printer product line. Through this agreement, consumers will find it simpler to purchase post-printing solutions, further enabling the workflow to be fully digitalized from part design through 3D printing and post-processing. In some circumstances, safety and sustainability issues can arise from the extremely manual or semi-automated nature of the current techniques of powder removal, claims PostProcess. PostProcess’ VAD system releases, transfers, and recovers loose powder particles while being thermodynamically regulated using video and infrared monitoring – according to PostProcess.
“We are proud to solidify this partnership with EOS, a global leader in industrial 3D printing, to help end users more easily adopt the complete workflow of additive manufacturing and scale their operations,” said Jeff Mize, PostProcess CEO. “EOS stands behind their sustainability objectives and shares in our dedication to ensuring additive manufacturing scales sustainably.”
“与后进程的这种合作关系提供了一种数字连接，可实现可追溯性和连接性。我们发现与后过程的完美搭配，为我们的客户提供可持续的自动化后处理，以使用其精致和复杂的零件使用使用EOS P 500EOS首席业务官Nikolai Zaepernick说。
后期过程Variable Acoustic Displacement™ (VAD) technology
VAD技术使用后过程的独家Automat3D®软件平台to thermodynamically control the depowdering process. Software-tuned frequencies can recognise geometries, and sound (pressure) waves can be used to mechanically de-cake powder without causing any damage. In a closed-loop solution that reuses powder and enables maximum sustainability, these functions are automatically tracked and modified in real-time.
Previously,a customer in Europe received the first Variable Acoustic Displacement (VAD) powder removal systemthat PostProcess Technologies had produced.VAD是后过程中的第五个技术家族，于2020年10月首次推出。该方法是在专利保护方面，是专门针对使用多喷融合（MJF）和选择性激光烧结（SLS）制成的脱皮部分的。客户是一个身份不明的消费者品牌，正在寻找该技术将端到端的数据连接添加到其SLS 3D打印工作流程中，以使其更安全，更可扩展。经过一段彻底的客户验证，该货物本身促使后进程继续进行全球商业发布。
可持续的减速和后处理解决方案
In addition to being crucial for optimizing the Selective Laser Sintering (SLS) 3D printing process,managing powder behavior is also crucial for manufacturers to reduce costs。
Both small businesses and mass manufacturers can increase their Return on Investment (ROI) while lowering their overall costs by reducing powder refresh rates. Not all users require such substantial machinery, despite the fact that large industrial SLS 3D printers frequently include dedicated powder handling stations to improve their production workflow.
Sinterit, a Polish manufacturer of printers, has consequently introduced its own line of powder-optimizing solutions. The firm’s powder toolset promises to speed up the printing preparation process for its customers, and its ATEX vacuum cleaner is made with comfort and safety in mind.
Previously, an瑞典金属3D打印机制造商Digital Metal引入了粘合剂喷气系统的自动化材料系统的自动化站。来自数字金属，DPS 1000是为了自动化后印刷粉回收的自动化，使用户更容易串行粘合剂喷射零件。作为最早实施新系统的组织之一Fraunhofer Iapt计划利用它来促进其对3D打印的工业化的更大研究，该研究效率为3D。
Elsewhere,Solukon Maschinenbau, a manufacturer of post-processing systems, had unveiled its automated de-powdering machine for polymer parts produced using SLS systems. According to Andreas Hartmann, Technical Director and Co-Founder of Solukon, theSolukon SFP770system is an “automated solution for industrial processing of powder-based AM parts.” TheSolukon SFP770在FormNext Connect上进行了演示online event in November 2020. Private US aerospace company发射器已将Solukon指定为粉末去除系统的值得信赖的供应商。For the post-processing of large 3D printed rocket parts, such as engines and combustion chambers,Launcherhad integratedSolukon’s SFM-AT1000-S缩减机器。
