M300 Metal 3D Printer

Technical Features

1. High‑performance Optical System: Equipped with a 500 W fiber laser system with closed‑loop power feedback. It adopts high‑speed scanning galvanometer with closed‑loop grating control, paired with quartz F‑θ‑theta lens and water‑cooled adjustable beam expander. The minimum spot size reaches 80 μm±10 μm with scanning speed ranging from 0‑7 m/s, ensuring forming quality for thin‑wall and fine‑feature geometries.
2. Self‑developed Bi‑directional Intelligent Recoating System: Features single‑blade bidirectional recoating driven by dual linear modules. Layer thickness is adjustable from 20‑100 μm and recoating speed from 10‑500 mm/s. Integrated blade‑collision overload protection triggers immediate alarm and emergency stop to safeguard the blade and working surface.
3. Closed‑loop Inert‑gas Protection Circuit: Self‑developed argon circulation & purification system with optimized right‑side air‑wall flow‑field design. Real‑time chamber oxygen monitoring keeps oxygen content ≤1000 ppm. Ambient‑oxygen monitoring is implemented; the unit will alarm and cut off main power upon threshold violation to eliminate risks caused by inert‑gas leakage.
4. High‑load Closed‑loop Build Cylinder: Z‑axis adopts servo motor plus grating‑ruler closed‑loop control. Positioning accuracy is 0.01 mm with minimum feed of 0.001 mm and Z‑axis load capacity ≥500 kg. Maximum substrate pre‑heating temperature reaches 220 °C to mitigate cracking of high‑stress materials such as titanium and high‑temperature alloys.
5. Fully‑independent Software Ecosystem: Self‑developed slicing and machine‑control software supports STL import, support generation and multi‑mode scan‑path planning, with pre‑validated process packages for multiple metal materials. It enables print resume after interruption, real‑time monitoring of oxygen level, blade position and machine status, plus automatic fault diagnosis and alarm. Core process parameters are fully open for R&D of new materials in research institutes.
6. Comprehensive Safety Protection: Safety interlock for build‑chamber door and emergency‑stop button are provided, complying with Class‑4 laser safety requirements. All components are brand‑new and conform to GB/T standards for machinery and laser safety.
