Specifications

TRUMPF TruPrint 2000: Technical Overview

Technology and Laser Sources

The TruPrint 2000 uses TRUMPF Laser Metal Fusion (LMF/LPBF) with two independent 300 W TruFiber fiber lasers at 1,070 nm. An optional upgrade enables 2 × 500 W for maximum throughput. The key differentiator from competitors: both lasers cover the entire build area (full-field multilaser) without split zones: eliminating the stitching lines typical of zone-divided multi-laser systems.

Optics and Switchable Beam Diameter

A patented TRUMPF optical system enables switching between 55 µm (HD mode) for maximum detail and 80 µm (HS mode) for higher speed: within the same build job.

Calibration

Calibrating the TruPrint 2000

• Ø 200 mm substrate plate leveling: Check at 5 points (4 quadrants + center) with a dial indicator. Tolerance: < 20 µm. Tip: Corners of rectangular parts fall near the cylinder edge: leveling errors there are critical for contour accuracy.
• Full-field dual-laser calibration: Position a standard calibration plate at the center of the build field. Verify positional accuracy of each laser (±10 µm XY) and their mutual overlap (≤ 20 µm).

Common defects

Common Defects on the TruPrint 2000

Porosity (Gas and Lack-of-Fusion)

Symptoms: low density in CT or Archimedes measurement; visible pores in metallographic sections. Cause: gas porosity, insufficient VED or trapped shielding gas; lack-of-fusion (irregular shape), excessive overlap from dual lasers or uncalibrated beam divergence. Fix: optimize VED; calibrate dual-laser overlap; check gas flow.

Residual Stress and Distortion.

What it is used for

Applications of the TruPrint 2000

Best Applications:

• Medical Implants: Hip cups, spinal cages, and porous titanium implants from Ti6Al4V. The cylindrical build volume is naturally suited to spherical and cylindrical implant geometries. Full-field dual-laser doubles throughput in serial production.
