ABSi (Acrylonitrile Butadiene Styrene – Biocompatible) is an ABS type thermoplastic with high impact strength. This material is stiffer and more durable than the standard ABS material, and appears translucent. That makes ABSi ideal for applications which require light transmission or flow monitoring, such as in the automotive industry or for medical device prototyping.

Technical Specifications

Standard lead time Minimum of 5 working days.
Standard accuracy ± 0.15% (with lower limit on ± 0.2 mm)
Minimum wall thickness 1 mm
Layer thickness 0.25 mm
Maximum part dimensions Dimensions are unlimited as components may be composed of several sub-parts. The maximum build envelope is 914 x 610 x 914 mm.
Surface structure Unfinished parts typically have a rough surface but all kinds of fine finishes are possible. FDM parts can be sandblasted, smoothed, colored/impregnated, painted and coated.

How Does Fused Deposition Modeling Work?

FDM is a filament-based technology where a temperature-controlled head extrudes a thermoplastic material layer by layer onto a build platform. A support structure is created where needed and built in a water-soluble material.
