UnionTech Lite800

The UnionTech Lite800 is an SLA 3D printer from UnionTech with a 800 x 800 x 550 mm build volume.

Specifications

UnionTech Lite800, Technical Specifications

Build Volume

800 × 800 × 550 mm (≈352 litres), one of the largest build volumes in the accessible industrial SLA class. Enables printing of full-scale automotive bumpers, architectural models, and massive industrial parts without splitting.

Laser Source

355 nm solid-state laser. Standard single-beam configuration with a high-speed galvanometer scanning system.

Optics and Scanner

Dynamic dual-axis galvanometer system with correction across the full working area. At 800 × 800 mm aperture, precise zonal alignment is critical to avoid stitching errors.

Layer Thickness

Adjustable from 0.07 to 0.25 mm (70–250 µm).

Calibration

Calibration of UnionTech Lite800

• Warm-up and Stabilization: leave the machine powered on for at least 30–45 minutes before any calibration. Thermal drift of the scanner at 800 mm aperture is significant and must stabilize before measurement.
• Galvanometer Calibration: launch the automatic procedure from the control menu. The system maps the 800 × 800 mm working area with at least 25 control points. Expected: ≤ ±0.10 mm across the full build volume.

Common defects

Common Defects on UnionTech Lite800

Corner Warping on Large Base Areas

Symptom: lifted or deformed corners on flat parts with base > 400 mm. Cause: polymerization shrinkage and uneven thermal management at large cross-section. Fix: split the part, add stiffening ribs, verify thermal control.

Scan-Zone Stitching Error

Symptom: visible line on the surface at galvanometric field zone boundaries. Cause: imprecise zone alignment at 800 mm aperture.

What it is used for

Applications of UnionTech Lite800

Suitable Applications:

• Architectural scale models: the build volume accommodates full city blocks at 1:100 scale or individual buildings at 1:20 in a single print: a key competitive advantage over smaller machines.
• Full-scale automotive prototypes: bumpers, mirrors, and full dashboards at 1:1 scale without assembly of segments.
