What your process engineer actually checks

What your process engineer actually checks

Large parts in one build

The 450 × 450 × 350 mm envelope prints a US Men's 14 last, a full fascia pattern, or a 1:50 building section in a single run — no mid-build stitching, no glued seams to sand out. Most mid-range industrial SLA caps XY at 250–300 mm.

Marble frame, measured accuracy

Recoater frame, elevator holder, and scan base are solid marble for thermal stability and vibration damping. Part accuracy holds ±0.1 mm under 100 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.

About this product

Kings 450Pro is a large-format industrial SLA 3D printer — a 17.7×17.7×13.8 in / 450×450×350 mm build chamber on a full-marble frame with vacuum recoating — built for shoe lasts, automotive patterns, dental models and architectural forms in a single run, without mid-build stitching or Z-seam artifacts.

Kings 450Pro industrial SLA 3D printer - large-format resin production on a full-marble frame
Kings 450Pro — 450×450×350 mm industrial SLA on a full-marble chassis.

Why teams specify the 450Pro

The four things a production engineer checks before committing a large-format SLA platform.

Large parts in one build

The 450×450×350 mm envelope prints a US Men’s 14 last, a full fascia pattern or a 1:50 building section in one run — no stitching, no glued seams to sand out.

Full-marble frame, measured accuracy

Marble across the recoater frame, elevator holder and scan base damps vibration and holds temperature — ±0.1 mm under 100 mm, ±0.1%×L above.

Solid-state 355 nm laser, variable beam

An Nd:YVO4 355 nm UV laser with a 0.08–0.8 mm variable beam narrows for detail and widens for fast flood-fill in the same job — scanning to 15.0 m/s.

Intelligent vacuum recoating

Position-aware vacuum recoating lays a uniform resin film with no blade contact on the part surface — consistent layers regardless of geometry.

How Additive Plus delivers your 450Pro

Configured to your resins, installed and calibrated on-site, printing on day one.

Step 01
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.

Step 02
Install, calibrate & train

A factory-trained technician handles setup, laser calibration and operator training on-site in the US — not a drop-ship.

Step 03
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

From teams running the Kings 450Pro

Unedited feedback from footwear, dental, and engineering shops.

★★★★★ 4.9 / 5 · 24 reviews
★★★★★

We print full shoe lasts in one run now — no more splitting a size 13 last and bonding the halves. Surface off the marble frame is consistent enough that our grinders barely touch it.

DR
Daniel R. Footwear Prototyping Lead · Athletic footwear studio
★★★★★

Accuracy holds across the whole 450 mm bed. We measured a full-arch batch and everything came in inside ±0.1 mm. The vacuum recoater means no witness lines on flat surfaces.

PN
Priya N. Dental Lab Manager · Full-service dental lab
★★★★★

Install and calibration were done in a day and the machine was printing production parts by the afternoon. Having engineers who actually run SLA answer the phone made qualification quick.

Common questions

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.

What build volume does the Kings 450Pro offer?
The Kings 450Pro prints at 450×450×350 mm — one of the largest XY envelopes in the industrial SLA class. That's large enough for most shoe lasts, automotive trim panels, and dental arch models without mid-build stitching or Z-seam artifacts.
Which resins are qualified for the Kings 450Pro?
Kings3D qualifies ABS-like (KS908C), durable ABS (KS408A), high-toughness (KS608C), rubber-like (KS198S), and clear (KS168C, KS158T) resins. Biocompatible and castable options are available — contact our team for the current validated list.
What does installation include, and what is the lead time?
Lead time is typically 6–8 weeks. Installation includes on-site setup, laser calibration, resin loading, and operator training by a factory-trained technician. Service and maintenance contracts are available.
Can I test the Kings 450Pro before committing?
Yes. Send your part files and our in-house 3D printing service will print samples in the resin of your choice, so you can evaluate surface finish and accuracy on a real part before you commit. For qualified buyers we can also arrange an on-site demo or a live print review of the Kings 450Pro before purchase.
What layer thickness and surface finish does the Kings 450Pro produce?
The Kings 450Pro prints at 0.05–0.20 mm layer thickness with 0.0005 mm vertical resolution. Its intelligent-position vacuum recoater lays a uniform resin film with no blade contact against the part, so flat surfaces come off the machine without witness lines or Z-seam artifacts. Surface finish is smooth enough that most footwear lasts, dental models, and engineering patterns need only light hand-finishing before use or moldmaking.
Why does the Kings 450Pro use a marble frame?
The Kings 450Pro's recoater frame, elevator holder, and scanning-system base are solid marble. At this build scale, marble's thermal stability and vibration damping keep the optical path and build platform aligned through long jobs, which is what holds part accuracy at ±0.1 mm for features under 100 mm and ±0.1%×L above that. It is a structural property of the machine, not a calibration setting that drifts between builds.
What post-processing does the Kings 450Pro require, and does Additive Plus supply it?
Parts printed on the Kings 450Pro are drained, washed to remove uncured resin, then UV post-cured to reach full mechanical properties. Large-format builds need a wash tank and cure chamber sized to the part — a desktop cure box will not fit a 450 mm shoe last. Additive Plus can spec and supply matched wash-and-cure equipment with the machine, and our engineers will set the post-cure protocol for each qualified resin.
