KamerMaker - Demo

The KamerMaker was up and running. PP thermoplastic granules are melted and extruded along a monsterous 'bowden' tube to the print head. The tube is heated PTFE with steel braiding. The setup works surprisingly well. Only problem is PP is prone to warping and cracking. PLA should work well .... :)

The machine runs without a heated bed (currently), but woodscrews drilled into the first layers(!) are pretty effective anchors. At this scale, running repairs are quite easy with woodscrews and steel wire.


The KamerMaker (RoomBuilder), capable of 3D printing large architectural objects with an epic 2x2x3.5m build area!


Launch party for, a project by DUS Architects (, at Tolhuistuin, Amsterdam.
