Not much information here other than with a 250mW laser, a kg of plastic powder and 50ml of thermo-gel, Replaser has managed to laser sinter some basic polymer forms in a kinda 2.5D printing (not quite 3D) that are really quite strong. 

Check out the pull test at 5:40 and the comparison of how brittle the material is with and without the thermo-gel. 

Not as poetic as the Inkjet Printer to 3D Printer Hack but still very impressive.
