Stereolithography (SLA) 3D Printing Service

Atlas Precision offers professional Stereolithography (SLA) technology, delivering the highest resolution and smoothest surface finish among 3D printing processes. SLA is the preferred choice when you need precise, detailed, and visually superior prototypes or end-use parts.

Why Stereolithography?

• Ultra-high resolution (down to 25μm layer thickness)

• Exceptionally smooth surface finish comparable to injection molding

• Excellent dimensional accuracy and tight tolerances

• Wide range of resin materials (standard, clear, tough, flexible, high-temp, castable)

• Superior detail reproduction for intricate features

Key Advantages

• Fast printing for small to medium sized parts

• Clear/transparent parts with optical clarity

• Biocompatible and medical-grade resins available

• Minimal visible layer lines

• Ideal for post-processing (painting, plating, vapor polishing)

Common Applications

• High-detail product prototypes and design validation

• Dental models, surgical guides, and aligners

• Jewelry design and master patterns

• Consumer electronics casings and concept models

• Clear lenses, fluidics, and optical components

• Master patterns for silicone molding or casting

Our SLA Capabilities

• Industrial SLA systems with large build platforms

• Multiple engineering and specialty resins

• Advanced post-processing: support removal, UV curing, sanding, painting, clear coating

• Full dimensional inspection and quality reports

• Free Design for Manufacturability (DFM) feedback
