MSc. Kuipers, T.

Tim Kuipers is PhD candidate at the Faculty of Industrial Design Engineering.

Academic Background

I have been a software engineer at Ultimaker working on toolpath generation (a.k.a. 'slicing') algorithms for three years before the start of my PhD. My current research is into changing the toolpaths of desktop 3D printers so as to enable spatially graded object properties. One example of such a model property is surface color. Using an off the shelf dual extrusion FDM system I have developed a method to print objects with the appearance of full grayscale imagery, which is more detailed than any existing approach. Another example of heterogeneous model properties is density. Infill patterns which support different infill density can be used with flexible materials, so as to make certain parts of a model more flexible than others. Printability is the main constraint of my research.
