Re: 3D printing, powder spreading

First of all thank you for sharing with us those great and detailed
informations !
I must tell you that I have read 2 or 3 times your posts and I have
printed them (I hope that I'll understand better because I'm not an
native english speaker and I have to find explanations for all
acronyms that you have been using).

I think that you had a good choice using thermal print heads in your
tests. Let me tell you why : on the market are several print head
producers for large format printers (like Xaar or Spectra). Those
print heads could be used with aggressive solvent based or UV curable
inks (I wonder now if uv curable inks could do the job of binder).
More than that those heads are working on a high speed and some of
them are built in such way as they can be heated up at around 60 deg
C. But all of them are using piezo technology. As you said thermal
characteristic it is probably very important otherwise I can't see why
the Zcorp did choosed this print head.

I'm playing now with a cnc (

) and you made me decide myself to put a print head on z axis and make
some tests. Unfortunately I'm living in eastern Europe and I cannot
find so easily this kind of special materials.

Could you give us links for a suppliers for -artistic molding plaster
and Elmer Brown Glue, which you have played with ?
