A new method for 3D printed surface smoothing wastes less material while achieving better accuracy:

Waseda University researchers have developed a process to dramatically improve the quality of 3D printed resin products. The process combines greatly improved surface texture and higher structural rigidity with lower cost, less complexity, safer use of solvent chemicals and elimination of troublesome waste dust.

[...] The Waseda researchers developed and tested a method called 3D Chemical Melting Finishing (3D-CMF), which uses a tool like a felt-tip pen to selectively apply solvent to particular parts of the printed piece which require smoothing. The new 3D-CMF method has major advantages over previous methods: removing less material to create less waste and achieve more accurate shaping; and using less solvent for better safety and lower cost. In addition, pen tips can be changed to further increase surface shaping accuracy. These improvements promise to move 3D printing into a much more attractive commercial position, as a realistic possibility for in-home consumer use.
