Re: [CAD_CAM_EDM_DRO] Ideal 3D printer?

Just as a side note:
I experimented with ( and ruined several) inkjet heads awhile back in
determining
what they would spray. This was in search of an inkjet PCB etch resist
attempt to no avail.
But, they will spray alcohol, so if a savy chem engineer has some way of
making
alcohol activate an adhesive agent with powder base, low cost
homebuild 3D printers could happen easily.?...

Just a thought...
