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.

Advantages of SLA with Xometry

Massive Capacity

Massive Capacity

We can quickly produce both prototypes and large batches thanks to the largest manufacturing network in Europe, with over 2,000 vetted partners

Fast Production

Fast Production

You will get your 3D printing fast delivered in as fast as 3-5 days.

Quality Assurance

Quality Assurance

We have strong QA procedures, controlled by an in-house team of QA engineers, which allows us to deliver high quality parts.

Engineering Check & Status Updates

Engineering Check & Status Updates

All designs are checked by engineers before they’re sent for 3D printing. After confirming your order, you will receive status updates on your production.

SLA Materials

  • ABS SL 7820 (Black)
  • PC heat (Translucent Amber)
  • True Silicone
  • Watershed XC 11122 ABS/PBT-like (Transparent)
  • Xtreme Grey Polypropylene/ ABS-like (Grey)
  • Xtreme White 200 Polypropylene/ ABS-like (White)

Pros & Cons of SLA 3D Printing

Smooth surface finishOnly resin / polymer materials
Can print clear/ transparent partsStructural strength is normally lower than with SLS, MJF, or FDM
High precisionLimited resistance to UV light if you use resin as the printing material
Fast: Xometry can deliver them in just 5 daysMore expensive setup => more expensive smaller series
Requires support elements
