Capability decision data

Technical fit for SLA 3D printing

Use this capability summary to decide whether the process fits the part before discussing tooling, lead time or price.

Best fit: Detailed visual prototypes, small precision models and smooth surfaces where appearance matters more than long-term production properties.
Design focus: Support contact, trapped resin, drainage, orientation, wall thickness and post-curing affect the result.
Material direction: Photopolymer resins are selected by visual, stiffness, temperature or specialty needs and should not be treated as direct thermoplastic equivalents.
Volume and cost logic: No hard tooling is needed; build volume, resin, support, washing and finishing drive cost.
Inspection focus: Inspect fine features, support marks, cure, warpage, surface, dimensional fit and resin-specific aging limits.
Compare against: Compare with FDM for economical functional models, SLS for durable nylon parts and molding for production material behavior.

Product Description

Our SLA 3D printing service produces high-detail resin prototypes with smooth surfaces, sharp features and accurate appearance for design review and product validation.

SLA is suitable for presentation models, small detailed parts, transparent prototypes, fit-check components and master models that need better surface quality than standard FDM printing.

Manufacturing Capabilities

Process	SLA resin printing with UV-cured photopolymer materials
Strength	Fine detail, smooth surface and good dimensional consistency for prototypes
Finishing	Support removal, sanding, polishing, painting, clear coating and assembly
Use range	Appearance prototypes, product models, medical models, small housings and precision samples

Materials and Options

Standard resin for detailed visual prototypes.
Tough resin for parts that need better impact resistance.
Transparent resin for lenses, covers and fluid-view prototypes.
High-temperature resin for selected heat-resistant samples.

Typical Applications

SLA printed parts are commonly used in consumer products, electronic housings, medical models, industrial design samples, display models and pre-mold appearance validation.

Example Project

A customer needed a smooth prototype housing before injection mold development. We printed SLA samples, sanded the visible surfaces, checked assembly gaps and helped the customer confirm design details before tooling.

Quality Control

Drawing and requirement review before production.
First article inspection before batch work.
Dimensional checks for critical features and assembly areas.
Appearance inspection for surface defects, color variation and processing marks.
Protective packaging and final confirmation before shipment.

What We Need for a Quote

Please send 3D files, 2D drawings, material requirements, quantity, target tolerance, surface finish, color, application environment and any inspection standard. If the design is still early, we can help compare process options before production.

FAQ

When should I choose SLA instead of FDM?

Choose SLA when surface finish, small detail and appearance are more important than the lowest prototype cost.

Can SLA parts be painted?

Yes. SLA parts can be sanded, primed and painted for presentation models or appearance review.

Are SLA parts suitable for functional testing?

They can be used for fit and light functional tests, but SLS, CNC machining or injection molding may be better for stronger load-bearing parts.
