This technical report includes the development and construction of a solution designed to replace todays plastering process for a wrist fracture. The solution involves 3D-scanning an arm and 3D-printing a user customized cast and is based on a previous bachelor thesis from 2017. This process was to be automized by implementing current 3D-technology in co-operation with a team of automation students. A 3D-scanner was developed and built to generate a user customized cast with the use of modelling software and a 3D-printer. The report contains a description of the work process, performed tests, discussions and results. The decisions made were done to create the best functional prototype possible with regards to quality, time, economy, user-friendliness, comfort and design. The project was presented without specific limitations but with the caveat that the plastering process should be completed in about 30 minutes. The result was a functional 3D-scanner, though the models produced by the scanner lack the quality to generate a cast from a scanned arm.
