Prototyping of an Individualized Multi-Material Wrist Orthosis using Fused Deposition Modelling

Abstract

The paper presents design and manufacturing process of an individualized wrist orthosis. The patient’s upper limb was 3D scanned and the orthosis was design using a CAD system. Each part of the orthosis consists of two different materials, that fulfill different functions. By using the double-head Fused Deposition Modelling machine it was possible to produce theses parts in a single process without the need for additional assembly operations. The orthosis has been tested for mutual fit of parts, strength and comfort of use.
