Large-Format SLA

2.1 Meters — One Print. No Assembly. No Seams.

The Kings SLA 2100 Pro delivers a 2100 × 700 × 800 mm build envelope — enough for full-scale automotive bumpers, door panels, and large industrial housings in a single run.
Full-Scale Output
Print Complete Automotive Parts Without Sectioning

Where traditional workflows require splitting large parts, bonding, and hand-finishing seams, the Kings SLA 2100 Pro produces complete automotive exterior components as a single continuous piece directly from CAD. A full bumper assembly, door surround, or fascia prints at 1:1 scale — dimensionally accurate to ±0.15 mm across the entire 2100 mm length — ready for fixture verification the moment it leaves the platform. The marble frame and closed-loop ball screw system maintain positional accuracy from the first layer to the last, regardless of part weight or platform position.

Machine Architecture

Full Marble Frame — Industrial Stability at 2.1 Meter Scale

Marble eliminates vibration and thermal drift. The 2100 Pro holds accuracy across multi-day continuous production runs.
Kings SLA 2100 Pro — machine structure and marble frame
Marble Construction
Granite-Hard Stability. Zero Thermal Drift.

Kings replaces steel with a full marble recoater frame, marble elevator holder, and marble scanning system base — a thermally stable, rigid structure that maintains positional repeatability across thousands of cycles. Ball screw rails with closed-loop servo control deliver ±0.01 mm repeat positioning regardless of part weight or ambient temperature variation. The Scanlab GmbH galvanometer scanner — sourced from the world leader in scan head precision — maintains consistent beam positioning at 15 m/s across the full 2100 mm span, eliminating stitch errors at large format.

Full Marble — All Three Structural Elements

Recoater frame, elevator holder, and scanning base are all marble — eliminating differential thermal expansion between elements, a root cause of dimensional drift in conventional large-format SLA systems that grows worse at longer build lengths.

Scanlab Galvo — German Precision

The galvanometer scanner is sourced from Scanlab GmbH, Germany — the global leader in laser scan head precision. Closed-loop galvo control maintains consistent beam positioning at 15 m/s, eliminating stitch error and beam deviation across the full 2100 mm span.

VarioBeam — Variable Spot, Maximum Speed

VarioBeam technology dynamically adjusts beam diameter from 0.08 mm for fine detail to 0.8 mm for bulk infill in real time. This delivers 20–40% speed improvement over fixed-beam systems without sacrificing surface quality or dimensional accuracy on critical features.

Industrial Applications

Built for the Work That Demands Both Scale and Precision

Automotive, aerospace, architecture, molds — wherever large and accurate matters, the 2100 Pro delivers.
Automotive
True-Scale Exterior and Interior Prototyping

Automotive design and engineering teams use the Kings SLA 2100 Pro to produce true-scale exterior body components — complete bumper assemblies, door surrounds, fascias, and interior console structures — directly from CAD at 1:1 scale. The 2100 mm build length eliminates splitting, bonding seams, and post-assembly alignment. SLA surface quality removes hand-finishing for concept presentations and design reviews, and dimensionally accurate output feeds directly into fixture and tooling validation workflows. Compare the Kings SLA 2700 Pro for the industry's largest build envelope.

Aerospace & Industrial
Large Structural Prototypes, Jigs, and Precision Tooling

Aerospace and precision engineering applications demand both scale and dimensional integrity. The Kings SLA 2100 Pro produces large structural prototypes, assembly jigs, and tooling aids at ±0.15 mm accuracy across the full 2100 mm build length. Marble-based vibration isolation maintains print quality in plant environments where floor vibration and temperature variation would otherwise introduce cumulative error over long builds. Closed-loop servo motion ensures the platform repositions to ±0.01 mm on every layer — critical when a 2-meter part must be within tolerance at both ends.

Architecture
Large-Scale Models & Site Layouts

Architectural firms print full building section models, structural detail mockups, and large-scale site layouts at 1:20 or 1:50 scale. The 2100 mm envelope accommodates multi-building campus arrangements in a single print run.

Molds & Tooling
Master Patterns for Casting and Forming

SLA surface quality makes the 2100 Pro ideal for master patterns destined for polyurethane, silicone, or vacuum-forming tooling. High-detail surface finish reduces post-processing before mold production, shortening tooling lead times significantly.

Sculpture & Display
Life-Scale Art, Props, and Cultural Installations

Museums, public art studios, and entertainment prop houses use the 2100 Pro to produce life-scale sculpture, cultural artifact reproductions, and large display installations impossible on any desktop or mid-size SLA system.

Competitive Analysis

Kings SLA 2100 Pro vs. 3D Systems ProX 800

How does the 2100 Pro measure up against the large-format SLA benchmark?

The 3D Systems ProX 800 has long been the widely-referenced standard for large-format industrial SLA. The Kings SLA 2100 Pro directly challenges that position with a substantially larger build envelope, comparable accuracy specifications, and a full marble frame architecture that eliminates vibration and thermal drift at industrial scale — all at a significantly lower acquisition cost. Rev1 Technologies provides US-based support, installation, and resin supply as an authorized Kings 3D partner in Auburn Hills, Michigan.

Common Questions

Kings SLA 2100 Pro — Frequently Asked Questions

Answers to the most common questions from engineers and procurement teams evaluating the 2100 Pro.
What industries is the Kings SLA 2100 Pro best suited for?
The Kings SLA 2100 Pro is purpose-built for industries that require large-scale, high-accuracy SLA output. Primary applications include automotive (full-scale bumpers, door panels, fascias, interior components), aerospace and defense (structural prototypes, assembly jigs, tooling aids), architecture (scale models, site layouts), mold-making (master patterns for polyurethane and silicone tooling), and large-scale artistic and cultural installations. Its 2100 mm build length makes it the right choice any time a part exceeds what a 1000–1700 mm machine can produce in a single run.
How does the full marble frame improve print quality vs steel-frame machines?
Steel frames expand and contract with temperature changes — a problem that compounds over 2100 mm of build length. Marble has extremely low thermal expansion and absorbs vibration rather than transmitting it. The Kings SLA 2100 Pro uses marble for the recoater frame, elevator holder, and scanning system base — all three primary structural elements. This eliminates the dimensional drift that accumulates in steel-frame machines over long builds and multiple production cycles. The result is consistent ±0.15 mm accuracy across the full 2100 mm platform, run after run.
What is VarioBeam technology and how does it affect print speed?
VarioBeam is Kings 3D's variable laser spot technology. The beam diameter adjusts dynamically between 0.08 mm (for fine surface detail and sharp edges) and 0.8 mm (for rapid infill of large cross-sections) within the same print job. Fixed-beam machines must compromise — either slow down for detail or sacrifice edge quality for speed. VarioBeam eliminates that tradeoff, delivering 20–40% faster print times compared to fixed-beam competitors at equivalent accuracy. The Scanlab GmbH galvanometer scanner provides the closed-loop control precision required to execute this at 15 m/s scan speed across 2100 mm.
What resins are compatible with the Kings SLA 2100 Pro?
The Kings SLA 2100 Pro is compatible with Kings 3D's own resin portfolio, including KS408A (the most widely used — high accuracy, tough, fine surface texture), castable resins, flexible resins, and engineering-grade materials optimized for automotive and industrial applications. Rev1 Technologies supplies Kings resin and can advise on material selection based on your application requirements. Third-party 355 nm photopolymer resins may also be compatible — contact Rev1 for qualification guidance before switching materials.
What does installation and commissioning involve?
The Kings SLA 2100 Pro is a large-format industrial machine requiring proper facility preparation — including floor load capacity, environmental controls (20–26 °C, humidity below 40%), electrical supply (200–240 VAC, 50/60 Hz, single-phase, 10 A), and ventilation for resin fumes. Rev1 Technologies coordinates installation logistics, on-site commissioning, and operator training as part of every 2100 Pro purchase. We will conduct a facility readiness review before delivery and provide a complete installation checklist. Contact Rev1 at (248) 707-2950 to begin the facility planning process.
