Specifications

Eplus3D EP-M150: Technical Overview

Laser

Single 500 W fiber laser; 1070 nm wavelength. Optimised for precision work with small geometries in dental and medical contexts.

Scanner

Galvanometric scanner with dynamic focus; gas consumption < 0.8 L/min per manufacturer data.

Build Volume

Cylindrical build chamber ⌀150 × 140 mm: the round form is specifically designed for circular nesting of dental arches and crowns.

Chamber / Shielding Gas

Closed chamber with argon or nitrogen; certified for reactive alloys at < 100 ppm O₂.

Layer Thickness

20–80 µm; typically 30–40 µm for dental parts.

Part Density.

Calibration

Calibration: EP-M150

Cylindrical Platform Levelling

4-point check with dial indicator; tolerance < 20 µm across diameter.

Laser Power

Power meter measurement; tolerance ±2% of nominal (500 W). >5% deviation: schedule service.

O₂ Monitoring

< 500 ppm for CoCr/316L; < 100 ppm for Ti and Cu.

Dental Test Coupon

ISO 22674 coupon after every powder lot change; marginal gap < 50 µm, no visual cracks at 10× magnification.

Common defects

Common Defects: EP-M150

Gas Porosity

Cause: Moisture in powder. Fix: Drying at 120°C / 4 h; storage < 30% RH.

Undercure in Thin Sections

Cause: High scan speed in <0.5 mm sections. Fix: Reduce speed + contour pass.

Bridge Distortion

Cause: Residual stress in long CoCr structures. Fix: Horizontal orientation + stress relief at 700–900°C.

Recoater Collision

Cause: Anatomical convexities catch blade. Fix: Orient anatomical surface downward + support structures.
