NeXt is an extremely durable resin, suited for very accurate parts with high feature detail, and for tough, complex parts with good moisture resistance and thermal properties. NeXt is ideal for functional prototypes and end-use performance parts like snap-fit designs, impellers, duct work, connectors, automotive housings and dashboard assemblies.

Technical Specifications

Standard lead time Minimum of 3 working days , depending on part size, number of components and finishing degrees
Standard accuracy ± 0.2% (with lower limit on ± 0.2 mm)
Minimum wall thickness 1 – 3 mm (depending on part dimensions)
Layer thickness 0.1 mm
Maximum part dimensions 500 x 500 x 520 mm
Maximum part dimensions can vary according to the chosen material and the geometry of the part
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.
