Eplus3D, headquartered in Hangzhou, China, has introduced the EP-M300L Laser Beam Powder Bed Fusion (PBF-LB) metal Additive Manufacturing machine together with its Production-Ready Automation Line. Engineered for continuous and batch production, the EP-M300L features a build volume of 300 × 300 × 450 mm, designed to balance production flexibility with efficiency and enable 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 high scanning speed and precision, states the company. This ensures consistent, high-accuracy production, suitable for demanding industries such as computers, communications and consumer 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 Additive Manufacturing machines that require extensive downtime for powder handling and part removal, the EP-M300L employs a decoupled architecture where the manufacturing module operates independently from the powder recovery station. The entire build cylinder can be quickly exchanged as a self-contained unit, reportedly enabling non-stop production.
By reducing idle time, this approach boosts Overall Equipment Effectiveness (OEE), enabling a single EP-M300L line to deliver output reportedly comparable to multiple traditional machines, while maintaining consistent quality and reducing manual intervention.

Centred on the EP-M300L, Eplus3D’s production-ready automation line is intended to integrate metal AM into a continuous industrial manufacturing cell. This integrated system combines the company’s core technology with dedicated ancillary modules, robotic automation, and intelligent software to deliver a complete “lights-out manufacturing” workflow.
Key processes, from manufacturing 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 closed inert atmosphere system. According to the company, the system maintains material integrity and safety throughout the powder lifecycle. This orchestrated setup is intended to reduce labour dependency, allowing a single operator to oversee multiple lines while maximising 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”, intended to support 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.
