Xtreme is a resin with good all-round properties including high impact strength, high elongation at break and excellent surface quality. Xtreme is ideal for tough enclosures, snap-fit assemblies and replacing CNC machined parts. Owing to its surface quality, this material is also suitable for finished models with a high level of detail.

Technical Specifications

Standard lead time Minimum of 3 working days , depending on part size, number of components and finishing degrees (offline orders)
4 working days (online orders)
Standard accuracy ± 0.2% (with lower limit on ± 0.2 mm)
Minimum wall thickness 0.8 mm
Layer thickness 0.1 mm
Maximum part dimensions 500 x 500 x 600 mm (offline orders)

Surface structure Unfinished parts typically have visible building layers on the surface but post-production finishes can achieve different effects, from high glosses to coarse textures. Stereolithography parts can be sandblasted, smoothed, colored/impregnated, painted, varnished, covered and coated.

How Does Stereolithography Work?

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 hardens the material corresponding to a cross section of the product, building the 3D part from the bottom to the top. The required supports for overhangs and cavities are automatically generated, and later manually removed.
