SLA Capabilities
| SLA Capabilities | Data |
|---|---|
| Maximum build dimensions | Dimensions are unlimited as components may be composed of several sub-parts. The maximum build envelope is 1800 x 600 x 900 mm. |
| Standard accuracy | ±0.3% (with a lower limit on ±0.2 mm) |
| Layer thickness | 0.07 – 0.12 mm (material dependent) |
| Minimum wall thickness | 1 mm |
| Surface structure | Provide smooth surface finishes with a very fine line of layering that greatly reduces post-finishing. |
Available materials for SLA
Quality Resin White works with SLA 3D printing at DHtech3D. Known for its smooth surface finish, high resolution, and good toughness, it is ideal for artwork, consumer electronics, household items, and more.
KEY CHARACTERISTICS
- Biocompatible and ISO 10993 compliant.
- High tensile, impact and flexural strength.
- Very high dimensional accuracy.
- Max part dimensions: 1800 x 600 x 900 mm.
Post-Processing
Washing
Remove any excess resin from the surface of the parts using an alcohol or ether wash.
Curing
Post-curing the print with light and heat helps solidify its material properties.
Sanding
Mainly removes blemishes and residue while smoothing edges left by support marks.
Finishing for SLA
- Spray painting in 3D printing is used to enhance the aesthetic and qualities of 3D printed part. It applies a fine mist of paint using a spray gun or aerosol can.
- Spray painting provides a uniform and smooth finish and a wide range of color options based on Pantone color.
- Spray painting helps hide layer lines and minor imperfections efficiently and add protective layers.
