On October 19, 2026, Nanjixiong learned that German post-processing supplier AM Solutions had launched a Powder Management System (PMS) and Direct Feeding System (DFS). The two commercial products create a fully automated closed loop for polymer SLS 3D printing, connecting powder recovery, mixing, screening and feeding.
The DFS connects directly to a single EOS SLS printer through fixed piping. Working with the F1 powder-processing system, it automatically sends processed powder from a Polybox storage container to the printer, eliminating manual handling. The PMS is intended for multi-machine production and can supply up to four EOS SLS machines simultaneously. It has two 180-liter Polyboxes; when one is empty, a valve automatically switches to the other. LED level indicators and a 360-degree warning light help prevent production stoppages caused by a lack of powder.
The systems use grounded aluminum piping and can transport powder up to 15 meters, with plug-and-play installation for different workshop layouts. Their fully enclosed design integrates air circulation and filtration to reduce dust exposure. EOS has deployed the PMS in a production environment, while the DFS has operated for approximately 10 months inside AM Solutions alongside an EOS P3 NEXT. Both systems will be displayed at Formnext next month.
Nanjixiong observation
Powder handling and mixing have long been labor-intensive steps in SLS mass production. An automated closed loop is essential infrastructure for moving from prototyping to mass production. AM Solutions' close integration with EOS also reflects a trend toward equipment and post-processing suppliers working together.
