• long overdue update

  After much delay i managed to get a powder coating gun and tried injecting some powder into a vacuum chamber.

  turns out any air stored in the powder expells the powder into a cloud as soon as it enters the chamber.

  So i would either need a very high velocity stream to reduce the divergence before impact or i would need to remove all air from the powder in an earlier chamber. i might be better off trying to use the cloud in the chamber to deposit powder. eitherway this project has fallen behind with other things on my mind. I'll hopefully get back on it later this year.

• the start of something wonderful

  I decided to write this before some patent trolls sit on it or some university research turns it into the next overpriced 3d printer.

  I'm super busy working on lots of other projects at the moment but I am actively trying to prove the concept.

  First, can i find a material that will stack up on itself reliably and is willing to take a charge.

  I need to make a test stand to fire the material out, i am thinking high velocity air jet or particle accelerator or maybe it doesn't have to be fast just accurately located and as it nears the base sticks to the nearest material. in which i could use a piezo injector. Could an electron beam be used to pre-charge the areas we want the material to stick to and then shoot a blind stream in the general direction, like powder coating.
