Method

Use the reprap to deposit and sinter

Deposit

Deposition volume is the vertical footprint (extrusion) of the model volume

Sinter

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 / 0.14deg 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.
