3D printed wood now a reality

A research team at Columbia University has successfully 3D-printed a block of wood, complete with a realistic internal grain using a voxel technique. The digital wood replicates olive wood and has been 3D printed on a Stratasys J750 PolyJet printer, which is equipped to print multiple colours using voxels. A voxel is the pixel-equivalent in 3D printing. The sample wood block was first sliced to 27 micro-metres (0.027mm) in width using a CNC mill, following which the ultra-thin slices were photographed using destructive tomographic imaging. All 230 images were fed into the Stratasys J750, which allows the designer to specify the desired quality for every voxel; this particular printer allows up to a maximum of 760 billion voxels. Elaborating on the process and the outcomes, the research team comprising of Fabian Stute, Joni Mici, Lewis Chamberlain and Hod Lipson, says that the digital wood 3D-printed by the machines has […]
