This 3D printing system converts waste sawdust into stunning wooden lamps and guitars

[RV_]

Desktop Metal's sawdust-printing outfit allows individual designers and large manufacturers to print elaborate wooden objects.

Excerpt:

"The printhead simultaneously injects a water-based ink that mimics practically any wood grain you would want, including rosewood, zebrano, ebony and mahogany, among others. Deposits of the binder and injection of the ink is done layer by layer, as per the contours of the rendering dictated by the 3D software.

The print head can build up to a height of ⅘ of an inch per hour (called 'Z height' in 3d printing parlance) until it reaches the finished level (and shape). Waste sawdust in the box is then collected for the next project while the whole piece is suffused with a non-toxic, bio-epoxy resin to give it strength. These 3D-printed wood parts function like regular wood ones -- they can be sanded, stained, polished, dyed, coated, and refinished, and can also accommodate screws and nails."
