Stereolithography (SLA) is a 3D printing technology that unlocks intricate design possibilities with precision and versatility. It's one of the most popular resin-based 3D printing technologies, combining low costs with advantageous mechanical attributes.
How SLA works
SLA works by utilizing the principles of photopolymerization.
​
The additive manufacturing process begins with a vat of liquid resin selectively cured by a UV light source, solidifying one layer at a time.​
The build platform gradually moves, curing and fusing each layer. This precise layering process produces highly accurate, intricate parts with smooth surface finishes.
SLA use cases
SLA is used in various applications, from product design and functional prototyping to end-use parts. This technology allows for thorough testing, validation, and design iterations. All this accelerates product development.
SLA by the numbers
Max Build Size: 2100 x 700 x 800 mm
Minimum Wall Thickness: 0.7 mm (depending on material and geometry)
Dimensional Accuracy: +/- 0.2%, minimum of 0.02 mm
Lead Times: Starting at 7 days

Available SLA finishes
Blasting
Fine particles, such as sand or glass beads, gently remove the outer layer of the print and achieve a smooth and uniform surface. This is especially beneficial for removing traces of support structures.
Prime and color spray painting
First, a primer is applied to create a smooth base. Then a range of colors can be added and intricate details, resulting in visually stunning and personalized prints.
Polishing
​Through careful buffing and smoothing techniques, SLA parts achieve a glossy and reflective surface that highlights the fine details of the print and offers good transparency.
UV-resistant painting
Protect your SLA prints from the damaging effects of the sun while adding a layer of visual appeal with UV resistant painting. This ensures prints retain their vibrant colors and structural integrity over time.
