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.

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.
