Abstract

Three-dimensional (3D) printing is an attractive rapid prototyping technology for the fabrication of 3D structures by the localized deposition of a reactive binder liquid onto thin powder layers in predominantly technical applications. A practical limitation is often the low green strength ofprinted samples, which can lead to a collapse of large and fragile structures during removal from the powder bed and the following depowdering procedure. Fibre reinforcement may improve green mechanical properties of printed samples, which was investigated in this study using a range of different short fibres added to a matrix of cellulosemodified gypsum powder. Mechanical testing ofprinted samples revealed a bending strength increase of180% and up to 10 times higher work of fracture values compared to non-reinforced printed samples.
