I'm doing a project on SLS, using a 20W CO2 laser. What king of feed rate
should I use for various materials (a range would be nice)..
I will be using an X-Y CNC table instead of scanners because the table is
cheaper/easier to control. I have calculated that my table is capable of
approx. 18"/min feed. I understand that could be WAY to slow, however, I can
turn the power down using the input power and gas pressure.
This is a very simple project, and I may only be able to draw a simple
square (because of time). I'm just looking to demonstrate the technique, and
perhaps play with it a bit, for my own enjoyment :)
Anyway, what would be suggested? A web page would be cool too.
Also, can anyone recommend any materials that would be cheap/plentiful for
demonstrating SLS? My dad suggested chocolate powder, so I'm up for anything
Thanks a ton,
