Abstract

3D printing is not one technique but many, depending on the used chemical principles for printing. One of these techniques is vat photopolymerization, in which light cures liquid formulations point-by- point and layer-by-layer, thereby creating 3D shapes. Such objects are currently manufactured of only one material. To increase their functionality, however, this research project aims to change the material properties within the printed object by changing the printing parameters. It will be possible to not only decide where the material forms but also what material forms. This will enable 3D printing of multi-material objects from one single print, in analogy to the advancement of black/white printing to colour printing.
