SLA 3D Printing Services

Stereolithography (SLA) is a powerful 3D printing technology that produces extremely accurate and high resolution parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping. It offers higher resolution printing than many other 3D printing technologies, allowing customers to print parts with fine details and surface finishes.

Pros & Cons of SLA 3D Printing

Advantages Considerations
Smooth surface finish Only resin / polymer materials
Can print clear/ transparent parts Limited resistance to UV light if you use resin as the printing material
High precision More expensive setup => more expensive smaller series
Fast: Xometry can deliver them in just 5 days Requires support elements

Build volume up to 736 x 635 x 533 mm up to 380 x 284 x 380 mm, while we normally recommend the maximum size of 356 x 280 x 356 mm up to 340 x 340 x 605 mm, but usually, we recommend the maximum size of 320 x 320 x 580 mm up to 914 x 610 x 914 mm up to 119 x 189 x 300 mm. Recommended size: Within 100 x 100 x 150 mm 250 x 250 x 325 mm up to 490 mm x 391 mm x 200 mm
Layer thickness min 0.02 ~0.08 mm ~0.1 mm and for water-tight parts 1.5 mm, when wall thickness is higher ~0.05-0.3 mm ~0.1 mm 0.02 – 0.08 mm depending on the material 0.004 mm
Minimum feature size 0.1 mm min 0.5 mm, 0.7 is recommended min 0.5 mm, 0.75 is recommended up to 0.2 mm min 1 mm is recommended 0.75 mm for cosmetic features, 1.5 mm for structural features 1.2 mm or greater for rigid. 2 mm or greater for rubber-like
Tolerance ±0.2% (± 0.2 mm) ±0.3% (± 0.2 mm) ±0.3% (± 0.3 mm) ±0.3% (± 0.3 mm) ±0.1% (± 0.1 mm). However, tolerances are not guaranteed on the first attempt at a new design. ±0.2% (±0.1 – 0.2 mm) ±0.1 mm for the first dozens of mm is typical, plus ±0.05 mm for every mm thereafter
