Re: 3D printing, powder spreading

Fernando, yes it was the leading zero causing the problem, I worked it
out but it was too late.

I use http://ep.espacenet.com/ for looking at patents its really good
and now allows pdf download.

Ballendo,

I've only been working on this a week really and I didn't even
consider looking at patents as the basic operation is just an inkjet
printer. I'm going to do the powder height adjustment with a pair of
pumps used for inflatable beds, the big syringe type. It will limit
my build size but provides two cylinders with close fitting pistons
for very little money.

For binder have a look in the patent, it mentions a few adhesives in
the recipes section. I'll be happy to wet plaster with ink or water
to start with just to prove it works.

The printer I have is a HP deskjet 1360. The gantry is now mounted on
some linear bearings, I'm going to use a dual cable drive (a la
photocopier) to get it moving, that way I can make the drive roller
the same size as the paper roller and its also much cheaper than belts
and pulleys. I'm using a 7 strand stainless plastic coated wire
bought from a tackle shop as the cable.
