Abstract:
This work presents the current development state of an automated algorithm for creation of knitting instructions for prosthetic liners directly from 3D scan data. This is a knitted medical textile worn by amputees, which on one hand mediates between the residual limb and the prosthesis and at the same time has to ensure appropriate protection and hygiene. Although the shape of the residual limb is very individual, liners have so far been manufactured in standard sizes. In the presented case, 3D scanning is used to obtain the geometry of the residual limb. The raw data is cleaned and adjusted manually and prepared for automated processing. The algorithms for slicing and preparing the intermediate knitting instructions are developed in Python language, using several functions inside of the open-source software Blender. The information for the loops of the knitwear is saved in intermediate bitmap (knitting chart), which is finally imported in specialized software for knitting machine design and used for the generation of the final program.
