Specifications

Laser

355 nm Nd:YVO4 DPSS laser, 800 mW. Third harmonic provides smaller beam waist and sharper cure edge definition versus 405 nm. The 450×450 mm build area requires longer scan paths: 12 m/s scan speed compensates.

Optics / Scanner

Dual-axis galvanometer scanner with a dedicated F-theta lens for a 450 mm field. Geometric correction via RPData Pro lookup table. Periodic 5×5-point scan field calibration is mandatory.

Build Platform

450×450 mm motorised Z-axis platform. Manual dial-indicator levelling; flatness <0.08 mm at 450 mm. Z travel: 400 mm.

Chamber / Gas

Closed enclosure with UV protection and VOC ventilation. Active enclosure.

Calibration

Platform Flatness

9-point dial indicator check; <0.08 mm/450 mm. Every 50–100 operating hours.

Scan Field Calibration (5×5 Grid)

CMM verification of 25 control points. Correction in RPData Pro. When deviation >±0.1%.

Jacobs Working Curve

For each new resin and batch: cure depth series → calculate Dp and Ec → optimal scan speed.

Recoater Blade

Blade clearance 0.05–0.10 mm above resin surface; parallelism across 450 mm. IPA cleaning when streaks appear.

Common defects

Warping of Large-Scale Parts

Cause: uneven cure shrinkage. Fix: ribs/stiffeners; low-shrinkage resin; orientation optimisation.

Scan Field Error at Edges

Cause: F-theta drift at extreme positions. Fix: full 5×5 recalibration.

Recoater Streaks

Cause: blade wear at 450 mm sweep; cold resin. Fix: blade replacement; heat resin.

Support Buckling at High Z

Cause: lateral recoat force on tall parts. Fix: larger-diameter supports; cross-bracing.

What it is used for

Automotive Prototypes

450 mm axis = dashboard panels and door trim in a single section for fit/function verification.

Medical Full-Scale Models

Anatomical models (pelvis, spine) in biocompatible 355 nm resins.

Consumer Electronics Housings & Assemblies

±0.1% accuracy for precise assembly fit testing.
