Olivier Van Herpt has been researching 3D printing technology for ceramics for about two years.  With his self-designed extruder, Van Herpt was able to experiment with textures, surfaces, shapes and sizes.  The result is a 3d printer that extrudes hard clay to create intricate patterns reminiscent of the artisanal work of yore.  Here is a collection of 3D printed ceramics by Olivier Van Herpt.
