Description

Overview
The LM-M120D Lite is a desktop-to-industrial metal 3D printer based on laser powder bed fusion (LPBF). It provides a compact footprint with integrated powder handling and filtration systems, suitable for producing dense metal components in dental, aerospace, mold, automotive and electronics applications. Standard laser power is 500 W with an optional 1000 W configuration. Build chamber control supports oxygen levels ≤100 ppm and operation under Nitrogen or Argon.

Key features

LPBF process for dense, high-strength metal parts
Compact, desktop-capable footprint for space-constrained environments
Integrated powder handling and modular filtration to enable single-operator workflows
Supports dental-grade precision and fine layer thicknesses for crowns, bridges and implant guides
Compatible with Co-Cr, stainless steel, titanium alloys and other industrial metals

Structure & operation

Compact design: 650 × 600 × 930 mm (L × W × H), machine weight ~180 kg
