What your process engineer actually checks
Large parts in one build
The 33×33×20 in / 850×850×500 mm envelope prints a full fascia pattern, a one-piece mold, or a batch of shoe lasts in a single run — no mid-build stitching, no glued seams to sand out. Most mid-range industrial SLA caps XY at 250–450 mm.
Marble frame, measured accuracy
Recoater frame, elevator holder, and scan base are solid marble for thermal stability and vibration damping across the full 850 mm bed. Part accuracy holds ±0.1 mm under 150 mm and ±0.1%×L above — a fixed structural spec, not a calibration claim. 355 nm solid-state laser, 0.0005 mm vertical resolution.
An applications engineer on the line
Resin selection, print-profile setup, post-cure protocol — answered by engineers who work with these machines, not a remote ticket queue. Sub-24h response, NDA standard.
Kings 850Pro is a large-format industrial SLA 3D printer — an 33×33×20 in / 850×850×500 mm build chamber on a full-marble frame with vacuum recoating — built to print full automotive panels, one-piece patterns and molds, architectural sections and batches of footwear lasts in a single run, without mid-build stitching or Z-seam artifacts.
Why teams specify the 850Pro
The four things a production engineer checks before committing a large-format SLA platform.
Large parts in one build
The 33×33×20 in / 850×850×500 mm envelope prints a full fascia pattern, a one-piece mold or a batch of shoe lasts in a single run — no stitching, no glued seams to sand out. Most mid-range industrial SLA caps XY at 250–450 mm.
Full-marble frame, measured accuracy
Marble across the recoater frame, elevator holder and scan base damps vibration and holds temperature — part accuracy holds ±0.1 mm under 150 mm, ±0.1%×L above, over the whole 850 mm bed.
Solid-state 355 nm laser, variable beam
An Nd:YVO4 355 nm UV laser with a 0.075–0.8 mm variable beam narrows for detail and widens for fast flood-fill in the same job — scanning to 15.0 m/s across the large bed.
Intelligent vacuum recoating
Position-aware vacuum recoating lays a uniform resin film with no blade contact on the part surface — consistent layers across a full 850 mm span regardless of geometry.
How Additive Plus delivers your 850Pro
Configured to your resins, installed and calibrated on-site, printing on day one.
Configure resin & profile
We match the qualified resin family — ABS-like, durable, high-toughness, rubber-like or clear — to your parts. Parameters are preset at the machine level.
Install, calibrate & train
A factory-trained technician handles setup, laser calibration and operator training on-site in the US — not a drop-ship.
Benchmark before you commit
Send your hardest geometry and target resin — we print a benchmark part on industrial SLA so you judge surface finish and accuracy in hand.
Qualified resin library
| Resin | Type | Typical use |
|---|---|---|
| KS908C | ABS-like | General engineering, functional prototypes |
| KS408A | Durable ABS | Snap-fit assemblies, jigs and fixtures |
| KS608C | High-toughness | Drop-test and impact-resistant parts |
| KS198S | Rubber-like (flexible) | Gaskets, soft grips, wearables |
| KS168C / KS158T | Clear / UV-clear | Optics mock-ups, fluid-flow housings |
Print parameters are preset for standard resins — no open-parameter development required. Ask our applications team about biocompatible and castable options for the 850Pro platform. See the full specification table below.
