On April Fools, our friends at FOC pulled a well executed prank on everyone by telling the world that they can 3D print in wood using sawdust. Well…it turns out you can 3D print in wood, using wood flour. Wood flour is aÂ fine sawdust like powder made from pulverized wood. A year ago Open3D student Meghan Trainor started doing tests on 3D printing in wood. Later on students Â Juliana Meira do Valle and Kate Lien took over the experiments and worked to improve the results. The team now 3D print in black walnut shell flour, pecan shell flour, wood bark flourÂ & wood flour. The team uses a powder based 3D printer which is basically a hacked version of a commercial system.Â In this case the team has used UF glue as a binder. The recipe for 3D printing in wood is to use 4 to 5 parts wood or nut flour and 1 part UF glue. The initial results are intriguing Â and prove once again that the Open3DP team is really pushing the envelope on hacking and improving 3D printers and 3D printing materials. The team is working on the AdderFab open source powder based 3D printer, 3D printing ice tea, 3D printing bone and now this. Thank you so much guys!
