Looks like 3d printing is starting to gain some momentum. Ran across this in my travels on the WWW.
Personal Factory (tm) - design, make & build your own custom products
And a short You Tube video showing the basics.
YouTube - How to use Google Sketchup for Ponoko 3D printing
Seeing as how I cannot afford $10,000 to purchase my own 3d printer, looks like the above is the next best step. Not sure about a helmet as the file size for 3d printing may not exceed 20 Mb. However, this should come in useful for gaunts and small pieces.
Has anyone used this before and if so, your results please?
Thoughts and opinions please.
