3D Systems ProJet 7000 HD

The 3D Systems ProJet 7000 HD is an SLA 3D printer from 3D Systems with a 380 x 380 x 250 mm build volume.

Specifications

3D Systems ProJet 7000 HD, Technical Overview

Technology

Stereolithography (SLA) with UV laser, the beam scans the surface of liquid photopolymer resin and cures it layer by layer from top down via high-accuracy galvanometer scanning.

Build Volume

380 × 380 × 250 mm: the largest platform in the classic ProJet HD line, enabling full-scale aerospace and automotive parts without splitting.

Resolution and Accuracy

Layer thickness 50 to 150 µm; accuracy 0.001–0.002 in/in: at 100 mm that is ≤ 0.05–0.10 mm, at 380 mm ≤ 0.38–0.76 mm. Recognized as a gold-standard for industrial SLA prototyping.

Optics and Laser.

Calibration

ProJet 7000 HD Calibration

• Laser and Galvanometer Check: Run the laser diagnostic from 3D Sprint. Expected: galvanometer scanning is linear across the full 380 mm field without corner compression. Tip: Diagonal distortion requires 3D Systems service: mirror angles are not a user adjustment.
• Four-Corner Levelling: Verify Z-zero at all four corners of the 380 × 380 mm platform. Expected: corner-to-corner difference ≤ 0.02 mm.

Common defects

Common Defects on the ProJet 7000 HD

Delamination: At thicker layer settings (> 100 µm) or with uneven laser power at the edges of the large scan zone, visible layer lines or delamination can appear. Fix: Increase cure depth 5–10%; verify power uniformity at platform periphery.

Large-Format Warping: Flat parts approaching 380 mm accumulate greater thermal stresses than on smaller machines.

What it is used for

ProJet 7000 HD Use Cases

Strengths: The ProJet 7000 HD is the preferred choice for aerospace structural prototypes, mounting brackets, and aerodynamic components where 0.001–0.002 in/in accuracy is a requirement. Automotive laboratories use it for interior trim prototypes, ventilation flaps, and panels.
