SLA
Stereolithography

Stereolithography is a laser-based technology that uses a UV-sensitive liquid resin. A UV laser beam scans the surface of the resin and selectively cures the material. This is how the 3D part is built from top to bottom. The required support elements for overhangs and voids are automatically generated and later removed manually.

technology

In stereolithography, an ultraviolet laser is used to create the components, the radiation of which locally hardens the thermoset resin. What is specific to the stereolithography process is that support structures are required that support the part during the construction process and connect it to the construction platform. In a first step, these supporting structures are applied layer by layer, and in the next step the actual component is created. After a layer has hardened on the resin surface, the build platform is lowered and a next layer of resin is applied. This process is repeated iteratively, layer by layer, until the construction process is complete.

Advantages

Stereolithography is particularly notable for the flawless level of detail in the prints. Even the smallest details are printed precisely. This type of 3D printing is particularly suitable for visual prototypes, detailed small parts and patterns for mold production.

The printing itself is quick and efficient and requires little post-processing. SLA is therefore chosen for urgent and detailed projects.

Applications

Layer thickness

0.02mm - 0.2mm (depending on material)

Surface structure

Unprocessed components usually have visible build-up layers on the surface, but post-processing can achieve different effects, from high gloss to rough textures. Stereolithography components can be sandblasted, smoothed, colored/impregnated, covered or coated.

Minimum wall thickness

1mm - 3mm (depending on part dimensions)

  • High Temp - Photopolymer Resin

  • TOUGH - Photopolymer resin

  • Flexible - Photopolymer resin
