Eplus3D, a leading manufacturer of metal additive manufacturing systems and solutions, introduces the metal PBF machine EP-M300L together with its Production-Ready Automation Line. Engineered for both continuous and batch production, the EP-M300L features a build volume of 300 x 300 x 450 mm, perfectly balancing production flexibility and efficiency for seamless integration into multi-machine automated lines.
Equipped with a high-performance multi-laser configuration (supporting up to six lasers) and an intelligent optical system, the EP-M300L delivers exceptional scanning speed and precision. This ensures consistent, high-accuracy production – perfect for demanding industries such as 3C electronics, tooling, and aerospace.

At the heart of the EP-M300L is its proven and highly efficient modular and removable build cylinder technology. Unlike conventional printers that require extensive downtime for powder handling and part removal, the EP-M300L employs a decoupled architecture where the printing module operates independently from the powder recovery station. The entire build cylinder can be quickly exchanged as a self-contained unit, enabling true non-stop production.
By dramatically reducing idle time, this approach significantly boosts Overall Equipment Effectiveness (OEE), empowering a single EP-M300L line to deliver output comparable to multiple traditional machines – all while maintaining consistent quality and reducing manual intervention.

Centered on the EP-M300L, Eplus3D’s production-ready automation line transforms metal 3D printing from a standalone process into a continuous, industrial manufacturing cell. This integrated system combines our proven core technology with dedicated ancillary modules, robotic automation, and intelligent software to deliver a complete “lights-out manufacturing” workflow.
Key processes – from printing and powder recovery to part handling and logistics – are seamlessly connected via automated stations and AGVs. Critically, the EP-M300L seamlessly integrates with a Closed Loop Powder System. This enables the automatic suction, sieving, and circulation of metal powder within a dedicated, closed-loop inert atmosphere system, ensuring material integrity and safety throughout the powder life cycle. This orchestrated setup significantly reduces labor dependency, allowing a single operator to oversee multiple lines while maximizing equipment uptime and material reuse. The result is a substantially lower cost per part and a significant increase in overall throughput.
Governed by a smart, data-centric platform, the EP-M300L line integrates with a Manufacturing Execution System (MES) and features in-process monitoring - including melt pool monitoring - to ensure full traceability and closed-loop quality control. Each component receives a “digital birth certificate”, guaranteeing consistent, reproducible quality and compliance with rigorous industry standards in aerospace, medical, and other high-stakes sectors.
This intelligent foundation not only automates production tasks but also delivers the predictability, documentation, and consistency required for certified serial manufacturing.
