Use the reprap to deposit and sinter
Deposition volume is the vertical footprint (extrusion) of the model volume
Requires a head with powder jet and sintering laser
Not sure of the optimal wavelength for PA12 sintering. The DVD burner is 650nm.
From this example, [500mw, <2.5mrad divergence, TTL control], a fiber optic carrier would be necessary for the head and trimming the beam width. Given this, a cheaper solution would fit.
