Precision SLA Resin 3D Printing for High-Detail Engineering & Aesthetics
Stereolithography cures liquid photopolymer resins with ultraviolet light to create injection-mold-smooth surfaces, crisp micro-features, and reliable snap-fit assemblies.
We check suction cups, drain hole placement, and thin walls before machine curing.
Affordable small batches for visual approvals and functional fit verification.
Why Stereolithography Delivers Superior Resolution
Unlike extrusion-based methods that deposit heated plastic beads, SLA cures liquid photopolymers layer by layer with pinpoint UV light for isotropic material strength.
Isotropic Strength & Watertightness
Chemical cross-linking during photopolymerization creates unified solid polymers without the directional layer weaknesses typical of FDM.
• Watertight enclosures and internal fluid channels
• Uniform mechanical behavior along X, Y, and Z axes
• No visible staircase layer lines on shallow curves
Cosmetic Master Models
Parts emerge with smooth, semi-matte surfaces ideal for investor presentations, consumer electronics housings, and silicone casting masters.
• Sharp embossing and crisp text down to small fonts
• Excellent primer adhesion for painted finish models
• Ideal for silicone mold patterns (urethane casting)
Functional Tough Formulations
Beyond brittle display resins, modern engineering resins simulate the elongation, impact resistance, and snap-back of molded ABS and polypropylene.
• Tough Resin for repeatable snap-fit interlocking clips
• High-accuracy mating features for electronic connectors
• Controlled post-curing cycle for mechanical stability
SLA Technical Process Specifications
In adherence to our engineering honesty rules, we verify fine dimensional requirements on a per-geometry basis during DFM evaluation rather than advertising generic tolerance claims.
