I have read the full article when I started the project. The time in which he did it and his result is commendable, but I never full agreed with his result and terminology.

He is not sintering, he is simply melting, resulting in extreme amounts of shrink. He uses lasers and drivers that cost more than this whole printer and somehow no-one can get a roller to work, even though all the industrial powder printers use this.

Having said that, it is my first goal to replicate his results before proceeding with plastics. I have ordered a ramps and am making final modifications to start printing again. That GlaDOS lamp project took a lot of my time.
