WHY THE 1450 PRO
The Precision Mid-Size SLA — Prototypes, Optical Parts & Finished-Quality Output
At 1,450 mm the SLA 1450 Pro covers the vast majority of large-format SLA work — full-width automotive interior sections, large consumer housings, and architectural models — without the weight and facility demands of the 1700 or 2700 class.
Most “Large SLA” Parts Land Inside This Envelope
The 1450 Pro shares its core with the bigger Kings platforms — the same 355 nm solid-state laser, closed-loop galvanometer scanning, and intelligent vacuum recoating — in a 222 × 177 cm footprint that fits standard industrial and studio floors. If your parts fit within 1,450 mm, this is the platform that delivers Kings large-format precision at the lowest cost and floor load of the family.
SURFACE QUALITY & PRECISION
Optical-Grade Output — From Clear Lenses to Paint-Ready Prototypes
88%+ Light Transmittance — Lenses, Covers & Light Guides Off the Plate
KS608 high-clarity resin on the 1450 Pro delivers light transmittance comparable to production-grade optical plastics — directly from the build platform. Lens covers for automotive lighting, display panels for consumer electronics, and light guide prototypes print at the 0.08 mm minimum beam with surface smoothness that goes to optical measurement without secondary polishing.
Tail Lights & Automotive Optics at Full Assembly Scale
Tail light assemblies, headlight lens covers, and turn signal lenses need optical clarity and precise geometry against adjacent body panels. The 1450 Pro prints them in clear resin at full assembly scale — lens geometry, mounting bosses, and seal channels in a single build — so optical teams evaluate real-world lux distribution and beam patterns before committing to injection mold tooling.
PAINT-READY SURFACE
Direct to Primer — No Sanding Cycle Between Print and Paint
Show-Gloss CMF Models — Straight to the Paint Booth
The combination of 355 nm laser, fine variable beam, and vacuum recoating produces a surface that accepts automotive primer directly from the plate. Appliance shells, automotive trim, and consumer electronics housings come off the plate ready for primer — studios running CMF approval cycles skip the overnight sanding and filler-primer loop that adds 2–4 days per iteration on FDM-based workflows.
Dashboards & Interior Assemblies — Presentation-Ready
Instrument cluster housings, center console inserts, and complex interior mock-ups sit comfortably within the 1,450 × 800 mm envelope. Interior teams take full-scale models straight from the printer to the studio, evaluating ergonomics, CMF choices, and fit against adjacent surfaces with physical parts instead of renders — compressing approval cycles from weeks to days.
PRODUCTION MASTERS
Full-Scale Masters & Mold Patterns — No Split Lines
Sanitaryware, Appliance & Product Masters in One Piece
From full-diameter appliance housings to sink, toilet, and faucet patterns, the 800 mm Y-axis covers the widest standard forms in one piece. Ceramic manufacturers cast directly from 1450 Pro masters — eliminating the seam line and the 3–5 days of joinery and seam-filling that split-mold workflows add.
Shoe Molds & Footwear Tooling — A Kings Specialty
Kings 3D platforms are a fixture in footwear manufacturing across Asia — full-size shoe mold patterns and sole tooling print overnight with the dimensional accuracy mold shops need for direct casting workflows. The same workflow applies to consumer product tooling of similar scale.
BUILT LIKE A MACHINE TOOL
Marble-Stabilized Frame — Precision That Holds Across Long Runs
Marble recoater frame, marble elevator holder, and marble scanning system base — 2,550 kg of thermal stability. The last part of the day measures the same as the first, even in non-climate-controlled shops.
Top-Brand Optics, Closed-Loop Everything
Optowave laser from the US, Scanlab galvanometer from Germany, and closed-loop motion on every axis. The intelligent position vacuum recoating system distributes resin evenly across the full 1,450 × 800 mm surface, while variable beam and variable power switch automatically between fine detail and fast fill — with differentiated upskin/downskin parameters per layer.

THE FULL PACKAGE
Production-Ready Day One — Everything in the Crate
The 1450 Pro ships as a complete production cell, not a bare machine. One DDP price covers the equipment below, delivered and installed.
From First Build to the Hundredth — Without Babysitting
Intelligent vacuum recoating keeps layer depth consistent across the full plate automatically, and the parameter database adjusts exposure per layer thickness. Run full-envelope single pieces or batch hundreds of smaller parts in one build — the workflow is the same.

BEYOND PROTOTYPING
Showpieces, Sculpture & Architectural Scale
When the Part IS the Product
Event installations, retail displays, sculpture, and architectural models — large-format SLA delivers smooth, finish-ready surfaces at scales FDM can’t reach without visible faceting and days of bodywork. Sectioned builds bond invisibly because every segment comes off the same calibrated platform. Explore the full Kings industrial SLA lineup for envelopes up to 2,700 mm.

HOW IT COMPARES
SLA 1450 Pro vs the 1.4 m Industrial SLA Class
All three share the marble-stabilized frame, 355 nm Optowave laser, Scanlab galvo, and vacuum recoating. The decision is envelope shape, floor load, and budget — the 1450 Pro typically sits between the 1200 Pro and 1700 Pro on package budget, with the widest X-axis of the two mid-size machines.
