ProtoFab SLA300

Precision Benchmark

True-to-CAD Accuracy and Surface Finish

Fabricates small and medium-sized parts up to 300 mm x 300 mm x 300 mm and 450 mm x 450 mm x 300 mm respectively with 0.05 mm accuracy, the highest among our printers, and with surface roughness as low as 0.05 μm. These standard tolerances outperform those of injection-molding and can even compete with CNC.

Precise & Compact

The perfect choice for enabling 3D printing in environments with limited workspace. The highly stable printing platform with granite reinforcement and an aerospace-grade aluminum Z-axis module make quick and efficient prototyping virtually effortless.

Outstanding Printing Speeds

Equipped with a top of the line galvanometer optical system by ScanLab Germany, the SLA300/450 displays top scanning speeds and enhances production efficiency significantly.

Wide Choice of Materials

A selection of over 10 different custom-designed printing materials with unique characteristics for functional prototypes and low-volume manufacturing.

Made-To-Measure Customization

We offer a considerable selection of customizations free of charge. Available upgrades include autofocus, automatic material refilling, environment sensors, as well as remote diagnostics and control, ensuring you are industry 4.0 ready.
