Element, developed together with pattern makers and foundries, creates exceptionally flawless investment castings. An antimony-free material, Element is suitable for high-end alloy castings with titanium and other super alloys. Paired with our Mammoth Stereolithography machines, Element produces accurate, repeatable parts regardless of size. Its low viscosity contributes to rapid draining. Patterns created with Element have lightweight, easily removable trace amounts of ash after burnout. This makes for a cleaner void in the ceramic mold, resulting in faster mold preparation and reduced risk of inclusions.

Technical Specifications

Standard lead time Minimum of 5 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 0.8 mm
Layer thickness 0.1 mm
Maximum part dimensions 500 x 500 x 580 mm
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.
