You will be positioned at our office in Sint-Denijs-Westrem, we develop the Materialise Control Platform, a software-driven, embedded hardware solution that allows you to take full control of laser-based AM machines.
Thesis subject: A simulator for a scan head used in a 3D printer.
Scan heads are used for laser control. They consist out of two galvanometers; one for movement in the x-direction and one for movement in the y-direction (see figure). An incoming laser beam enters the scan head through an entrance aperture. It is deflected by the first reflecting mirror (the mirror for the x-direction in the figure) and irradiates onto the second mirror (y-direction) which on his turn also deflects the laser beam. The mirrors are attached to galvanometers that can rotate around a certain axis. This way the laser beam is projected onto an image plane, which is the build platform in the case of an additive manufacturing machine. A single galvanometer can only deflect a laser beam along a line in the image plane and over a certain restricted angle (±5° to ±10°). This angle restriction is what defines the maximum size of a scan field.
Qualifications & Experience
Your goal is to make a software model of a scan head. An analysis of the dynamics of a scan head will be needed to define an accurate model. The software model will be used in a LabVIEW environment in a SIL (Software In the Loop) configuration. The minimal inputs of the model are the x and y set points and a sample frequency and the outputs of the model are the x and y feedbacks. Also a set of configuration parameters will be used to characterize the dynamics of a different scan head type.
You will also make (or propose to invest in) a hardware platform that, in combination with the software model, can be used as a HIL (Hardware In the Loop) configuration.
