DIY Laser Sintering

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.

    Very cool.

    It wont be long before we see someone takes it further… assemble a blue hacked laser on a $50 X-Y CNC with an Arduino controller hooked to a laptop and taking orders :-D

    I am just wondering, let’s say we have an ultra-bright LED panel and a way to focus the light down to a point, would it work too? Or is a laser required?

      Cold LED light no matter how concentrated wont do it.
      Laser (even hacked DVD drive burner) can reach a temperature enough to sinter powdered plastic plus it’s beam is so thin .. perfect for the job.
