Concept Laser X Line 2000R

The Concept Laser X Line 2000R is a DMLS 3D printer from Colibrium Additive with a 800 x 400 x 500 mm build volume.

Specifications

Concept Laser X Line 2000R: Technical Specifications

Laser

Two 1000 W ytterbium fiber lasers operating simultaneously across the build field; build rate up to 120 cm³/h. Among the few commercial DMLM machines with dual kW-class laser configuration.

Optics / Scanner

F-Theta optics with high-speed galvo scanners; spot diameter optimized for 1000 W mode (~100–200 µm); scan speed up to 7 m/s.

Platform

Rotating dual build-module architecture: the key differentiator of the 2000R. While module A builds, module B cools, depowders, and reloads for the next job. Z-axis 500 mm; substrate plates in tool steel or specialized Al alloys.

Chamber / Inert Gas.

Calibration

Calibration of the X Line 2000R

Dual build-module leveling: individual verification per module; ≤ 50 µm across 800×400 mm field; mandatory after every rotation in production mode.

Dual-laser verification: 1000 W lasers require thermal lensing monitoring; validate the overlap zone with a metallographic coupon at every parameter change.

O₂ inerting: verify O₂ ≤ 0.1% after every rotation operation; micro-leakage during rotation is a documented risk.

Common defects

Common Defects and Corrections

Porosity in Al alloys: hydrogen porosity from damp powder. Fix: dry at 80°C/2 h; VED 60–70 J/mm³; maintain O₂ < 0.15%.

Warping in large-format parts: thermal stresses in 400–700 mm parts. Fix: massive base supports; island scan rotation; substrate preheating.

Recoater streaking: at 800 mm width even minor blade deflection is visible. Fix: replace blade; resieve powder; stop build if streaks appear.

What it is used for

Use Cases

Aviation Al structures: Premium AEROTEC/Airbus use the system for AlSi10Mg structural panels; 800 mm X-axis enables monolithic parts without welding.

Aerospace Ti structural parts: dual-laser 120 cm³/h under AS9100 conditions is economically justified for batches of 5–50 Ti parts.
