Profile: Materialise n.v. offers a broad range of rapid prototyping, tooling and digital CAD software. Our RSM software enables the automated design and rapid manufacturing of hearing aid shells. This software reads a 3D scan of the ear impression and guides the operators step-by-step through the shell design process. The steps include fitting the raw impression to the correct instrument size, converting it to a shell, adding a venting channel, simulating the placement of components, integrating a wax guard and a faceplate and performing quality control tasks.
