Eplus3D Launches EP-M300L and Automation Line for High-Volume Metal AM

Hangzhou-based Eplus3D has introduced the EP-M300L, a Laser Beam Powder Bed Fusion metal AM machine built around a 300 × 300 × 450 mm build volume, alongside a Production-Ready Automation Line designed to push metal additive manufacturing into genuine high-volume, continuous industrial production.

The EP-M300L's multi-laser configuration scales up to six lasers, paired with what Eplus3D describes as an intelligent optical system to deliver consistent scanning speed and precision across long production runs. The machine features a removable build cylinder, a detail that signals its intent from the start: minimizing changeover time between builds to keep the line moving. Eplus3D engineered the system for both continuous and batch production modes, with the explicit goal of dropping cleanly into multi-machine automated cells.

That automation context is where the Production-Ready Automation Line comes in. Centered on the EP-M300L, the system combines Eplus3D's core PBF-LB technology with dedicated ancillary modules, robotic automation, and intelligent software to deliver what the company calls a complete "lights-out manufacturing" workflow. The throughput case Eplus3D makes is bold: by cutting idle time and boosting Overall Equipment Effectiveness, a single EP-M300L line can deliver output reportedly comparable to multiple traditional machines while reducing manual intervention.

The software stack backing this up is built around a smart, data-centric platform that integrates with a Manufacturing Execution System and includes in-process melt pool monitoring for closed-loop quality control. Every component produced gets a "digital birth certificate," providing the traceability documentation that aerospace, medical, and other high-stakes manufacturing sectors require for certified serial production. As Eplus3D puts it, the platform "not only automates production tasks but also delivers the predictability, documentation, and consistency required for certified serial manufacturing."

Industries Eplus3D has explicitly targeted with the EP-M300L span a wide band of metal AM's most demanding applications: aerospace and aviation, automotive, energy, oil and gas, machinery, tooling, healthcare, 3C consumer electronics, and semiconductor manufacturing.

Eplus3D frames the EP-M300L not as a finished destination but as a deliberate stepping stone. "It represents a foundational step in our ongoing roadmap toward full-scale automation," the company stated, with next-generation models including the EP-M400, EP-M550, and EP-M650 already in development. Those models already appear alongside the EP-M300L in Eplus3D's published product lineup, which currently spans from the compact EP-M260 up to the large-format EP-M2050.

The throughput and certification claims remain vendor-reported for now, without independent benchmark data to verify the comparable-to-multiple-machines assertion or specifics on which aerospace or medical standards the system is positioned to meet. Those are the questions worth putting directly to Eplus3D as early customer deployments come online.
