Visual prototypes
Models with smooth surfaces, defined edges and details for presentation or review.
Smooth surfaces and fine geometry
High-detail SLA 3D printing
Resin-based printing for precise small parts, visual prototypes and models where surface quality matters.
- Typical tolerance
- ±0.1 mm or ±0.05% (whichever is greater)
- Surface
- Smooth with fine detail
- Post-process
- Wash and UV post-cure
SLA forms a part by curing liquid resin with light. It reproduces small features and has less visible layering than FDM. Printed parts are washed, post-cured and inspected so the resin reaches its intended properties.
When SLA is the right process
Small precise components
Compact geometry, fine text and small features that coarser processes struggle to reproduce.
Master patterns
Detailed models for casting, form trials or subsequent manufacturing steps.
Detail depends on resin and orientation
Different resins prioritize stiffness, toughness, heat resistance or transparency. Choose according to the real application, not just a colour or material name.
Typical tolerance is ±0.1 mm or ±0.05%, but supports, post-curing and geometry affect the result. Identify visible surfaces and critical dimensions before printing.
- Mark cosmetic surfaces where support marks must be minimized
- Describe mechanical and thermal requirements
- Avoid closed cavities without drainage
From resin selection to finished part
- 01
Review geometry
We assess walls, features, cavities, orientation and support locations.
- 02
Print and wash
The part is printed in the selected resin and cleaned of uncured material.
- 03
Post-cure and inspect
UV curing develops intended properties before support removal and inspection.

SLA printing questions
How accurate is SLA printing?
Typical tolerance is ±0.1 mm or ±0.05%. Final accuracy depends on part size, shape, supports and post-curing.
Are SLA parts brittle?
Standard resins can be more brittle than many thermoplastics, but engineering resins can prioritize toughness, flexibility or heat resistance.
Why do some surfaces have small marks?
SLA needs supports that leave contact marks when removed. We plan orientation to move them away from important surfaces.
Can SLA produce clear parts?
Clear resins exist, but actual transparency also depends on geometry and finishing. Specify this requirement before quoting.
Can SLA be used for functional parts?
Yes, provided the selected resin meets the mechanical and thermal conditions. Describe loads and environment for assessment.
When is FDM a better choice?
FDM is often better for larger parts, a wider thermoplastic range and economical functional components where a perfectly smooth surface is not essential.
