Bolanos Arriola, J. (author), van Oudheusden, A.A. (author), Flipsen, Bas (author), Faludi, Jeremy (author)This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is an iterative process in which the part is analysed, redesigned,...book 2022
