Kings SLA 1200 Pro

The 1200 Pro divides its build field between two independent Scanlab galvanometer scanning heads. Each head handles its half of the platform at full 15 m/s speed — one from the left, one from the right — with the stitching zone at the centerline calibrated by Kings 3D control software to eliminate any visible seam in the final part. For large flat cross-sections like shoe sole molds and panel skins, the dual-laser advantage is immediately measurable: build times that would take 8 hours on a comparable single-laser system complete in under 5. The accuracy at the stitch zone matches the rest of the field — ±0.15 mm — because the galvo positions are calibrated relative to a common spatial reference during factory commissioning.

Dual-laser scanning introduces higher-frequency vibration than single-laser systems — two galvanometer assemblies moving simultaneously create twice the mechanical excitation. The 1200 Pro's full marble structural system absorbs this entirely. The marble recoater frame, elevator holder, and scanning base all have natural vibration damping coefficients that prevent galvo movement from coupling into Z-axis positioning errors. Layer flatness controlled to 0.006 mm across the full field, regardless of scanning speed or laser load.

The 1200 Pro's 1,200×800 mm envelope handles full automotive interior cross-sections — complete dashboard sub-assemblies, door panel skins with integrated grab handle geometry, and instrument cluster housings at 1:1 scale. Interior design teams use the dual-laser speed to run multiple iteration cycles per day: a full dashboard section that prints overnight on a single-laser system completes in an afternoon, allowing morning review, afternoon revision, and same-day reprint. KS408A surface finish accepts automotive primer directly off the plate.

Footwear OEMs and mold shops use the 1200 Pro's 800 mm Y-axis to nest multiple sole mold sizes across the build platform — EU 36 through EU 46 in a single job. The dual-laser system cuts per-mold print time to where seasonal tooling samples that previously required two weeks of single-laser runs complete in 3–4 days. Surface finish off the marble-based system eliminates polishing steps that traditional tooling workflows require before first shots.

At 1,200 mm × 800 mm, the 1200 Pro prints full 1:50 scale models of mid-size commercial buildings as a single piece — no section assembly, no seam lines between modules. Architectural model shops use the dual-laser throughput to turn around client-facing presentation models within 24 hours of design freeze. Sculptors use the 650 mm Z-height for bust-scale masters that go directly to bronze casting or gallery display without assembly.

Industrial manufacturers use the 1200 Pro for large casting patterns, composite lay-up mold tools, and vacuum forming tooling that previously required CNC machining lead times. The 1200 Pro prints them directly in KS408A or KS608 engineering resin, with dimensional accuracy that supports first-article inspection on casting outputs. Lead time from design to tool: 1–2 days vs 2–3 weeks machined. The dual-laser system makes the economics work even on mid-volume tooling where per-part time matters.
