Our SLA printing capabilities are designed to overcome the most demanding engineering challenges, ensuring your projects move from concept to physical validation without friction or compromise.
Unrestricted Geometric Freedom: Break free from the limitations of traditional tooling. We effortlessly produce hollow structures, complex undercuts, and thin-walled enclosures that reduce overall assembly weight without compromising structural rigidity.
Exceptional Surface Aesthetics: The inherent nature of our stereolithography process yields parts with a buttery-smooth exterior. This eliminates the stepped, rough textures often associated with standard printing, making the parts immediately ready for high-end optical or aesthetic applications.
Agile Iteration Cycles: Concept modifications are executed swiftly. With our optimized workflow, revised digital models are transitioned to the print bed instantly, providing your team with updated physical prototypes in record time.
Scalable Production Volume: From a single, life-sized exhibition sculpture to a small-batch run of specialized mechanical housings, our infrastructure adapts to your volume requirements seamlessly, minimizing inventory holding costs.
Sustainable Material Utilization: Additive construction means material is only placed exactly where it is needed. Uncured resins are efficiently recycled within our closed-loop system, reducing environmental impact and driving down per-unit material costs.

Selecting the correct material is critical for the functional success of your components. We stock a comprehensive library of engineering-grade resins and polymers, each formulated to mimic the specific tactile and mechanical properties of final production plastics.
Standard Photosensitive Resin: Delivers exceptional detail resolution and a smooth, rigid finish. Ideal for visual prototypes, intricate jewelry casting patterns, and detailed anatomical models where visual fidelity is paramount.
High-Toughness Resin: Engineered to withstand significant stress and strain. This material mimics the impact resistance of ABS, making it the perfect choice for snap-fit joints, living hinges, and rugged protective enclosures.
High-Temperature Resistant Resin: Capable of maintaining dimensional stability under extreme thermal loads. This is indispensable for under-the-hood automotive testing, hot fluid routing, and aerospace environmental validation.
Transparent & Translucent Resin: Offers glass-like clarity after post-processing. Essential for fluid flow visualization, optical light guides, and premium consumer packaging prototypes.
Thermoplastic Alternatives: Beyond resin, we offer robust PLA, PETG, and Nylon for applications requiring high strength-to-weight ratios and superior wear resistance in functional mechanical assemblies.

Dimensional accuracy is the bedrock of functional prototyping. Our specialized equipment and strictly calibrated environments ensure that every printed layer aligns flawlessly with your CAD data, guaranteeing that your parts will fit together securely during final assembly.
Micron-Level Accuracy: Our Uniontech SLA printers maintain a strict standard tolerance of ±0.1 to 0.2mm across the build volume, ensuring precise mating surfaces for complex multi-part assemblies.
Ultra-Fine Layer Resolution: By curing resin at microscopic layer heights, we capture the sharpest edges, the smallest embossed text, and the most delicate surface textures with absolute crispness.
Design for Manufacturability (DFM): Our engineering team provides comprehensive design feedback before printing begins. We analyze your models for optimal wall thickness, ideal support placement, and proper hole sizing to prevent warping and ensure structural integrity.
Consistent Repeatability: Whether you order one prototype today or fifty identical parts next month, our tightly controlled thermal and optical printing environments guarantee that every single piece matches the exact specifications of the first.

A prototype should not only function like the final product but also look and feel exactly like it. Our comprehensive suite of in-house post-processing techniques transforms raw printed parts into showroom-ready masterpieces.
Flawless Painting & Color Matching: We utilize precise RAL and Pantone color matching systems. Our spray painting process applies an even, durable coat that resists chipping, giving your parts a premium, injection-molded appearance.
Advanced Metallic Coatings: Elevate plastic parts with our electroplating, chrome plating, and nickel plating services. These finishes provide a cool, metallic touch and enhanced surface hardness, perfect for reflective automotive trims or luxury consumer goods.
Tactile Enhancements: From the aggressive matte grip of sandblasting to the mirror-like gleam of hand-polishing, we tailor the tactile feedback of your components to match your exact ergonomic requirements.
Precision Branding: We offer crisp silk screening and permanent laser marking directly onto the curved or flat surfaces of your printed parts, ensuring logos, serial numbers, and instructional graphics remain legible and professional.
Protective DLC Coating: For parts subjected to high friction, our Diamond-Like Carbon (DLC) coating drastically reduces wear and tear while providing a sleek, dark aesthetic.

In modern product development, time is your most valuable asset. Our facility is structured to eliminate bottlenecks, transforming your digital concepts into physical parts with unprecedented velocity.
Rapid 4-5 Day Turnaround: Our standard production cycle ensures that custom orders are printed, post-processed, and prepared for dispatch in less than a working week, keeping your project timelines aggressively on track.
24-Hour Expedited Prototyping: For critical, time-sensitive projects, our agile production cells can rush sample creation, delivering a physical prototype in your hands within 24 hours of file approval.
Massive Production Capacity: Operating out of a 2000 square meter facility with over 50 dedicated staff members, our monthly capacity exceeds 1,000,000 pieces. We easily absorb sudden spikes in volume without compromising delivery dates.
Streamlined Workflow: From the moment your CAD file is uploaded, our automated slicing software and dedicated project managers work in tandem to optimize the build strategy, ensuring continuous, 24/7 machine operation.

Trust in your components is non-negotiable, especially when they are destined for critical testing or end-use applications. We implement a rigorous, closed-loop quality control system that monitors every stage of the manufacturing journey.
CMM Precision Testing: Our quality control laboratory is equipped with advanced Coordinate Measuring Machines (CMM). We probe complex geometries to verify that every dimension falls strictly within the agreed-upon tolerances.
100% Pre-Shipping Inspection: No part leaves our facility without human eyes and precision instruments verifying its integrity. We conduct full-size pre-production model inspections and comprehensive appearance checks.
Real-Time Process Monitoring: During the lengthy curing process, our technicians and automated sensors continuously monitor resin temperature, laser intensity, and layer adhesion to prevent microscopic defects before they propagate.
Strict IP Protection: We treat your proprietary designs with the highest level of security. We readily sign Non-Disclosure Agreements (NDAs) and utilize secure data servers to guarantee your intellectual property remains strictly confidential.

Transitioning from an initial prototype to functional end-use parts often requires multiple manufacturing disciplines. We bridge this gap by seamlessly integrating additive and subtractive technologies under one roof.
3D Printing Meets 5-Axis CNC: While SLA provides incredible geometric freedom, certain critical mating surfaces require the absolute precision of machining. We combine SLA with 5-axis CNC machining to achieve astonishing tolerances of ±0.005mm on designated features.
Comprehensive Project Management: We handle the entire lifecycle of your product. From digital model optimization and material selection to printing, precision surface finishing, final assembly, and custom packaging.
Material Versatility: Should your project evolve beyond resin, our facility seamlessly transitions your designs to SLS and SLM processes, allowing for the creation of high-performance nylon, plastic, and dense metal components.
Seamless Scaling: Because we control both rapid prototyping and precision machining in-house, scaling your project from a single test unit to a small-batch production run of non-standard industrial parts is completely frictionless.

Our high-precision manufacturing services provide tailored, physical solutions to complex engineering bottlenecks across a diverse spectrum of demanding industries.
