Product Overview
GPT Precision provides SLA 3D printing for suitable custom prototypes, appearance models and detailed resin components.
Stereolithography uses a light-curable resin to build a part layer by layer.
The process can produce detailed geometry and smooth-looking surfaces, although the delivered appearance and performance depend on resin selection, build orientation, support placement and finishing.
Key Features
- SLA may be considered for concept models, appearance evaluation, detailed housings and components intended for selected fit or assembly checks.
- The process and material should be selected according to the sample's intended purpose.
- A visual prototype may not have the same mechanical properties or durability requirements as a functional production component.
Manufacturing Considerations
- SLA components commonly require support structures during printing.
- Support contacts can leave visible marks or require additional finishing.
- Before production, identify cosmetic faces, locating surfaces and areas where support marks are acceptable.
- The proposed orientation and support strategy should consider the part geometry and appearance requirements.
- Cleaning, post-curing and any additional sanding, polishing or coating can affect the delivered surface condition.
- Where a surface controls assembly fit, the final acceptance requirements should be based on the specified post-processed condition.
- Coating or material removal may affect critical clearances.
Quality Control & Inspection
- Appearance is evaluated according to agreed references and viewing conditions where specified.
- Critical dimensions and assembly fits are checked according to the approved project requirements.
- Material availability, finishing options and inspection scope are confirmed during project review.
Specifications to Confirm
| Resin grade | Confirm the grade and appearance requirements during project review. |
|---|---|
| Finish and post-cure | Specify the delivered condition and any surfaces that must remain uncoated. |
| Visual reference | Agree on the reference sample or drawing notes and viewing conditions. |
| Fit acceptance | Identify the mating component and check seating after the specified finishing. |
Assembly Considerations
Visible surfaces
Mark cosmetic zones and areas where support contact marks are acceptable.
Locating surfaces
Identify the faces that locate the part and any that require masking.
Finished fit
Check seating against the specified mating component in the delivered condition.
