Hello, Andrew,

The leverage Z-Corp uses is voiding the warranty and maintenance
agreement for using non-Z-Corp materials in the 3D printer.
Note that I am seeing refilling kits in the stores besides the original
HP ink jet printer cartridges.

I think that the crux here is that Z-Corp has always stated that they
haven't the resources to do Research and Development
to improve their own product. The example I quote was when Mike Bailey
at UCSD/SDSC printed out a replica of the 3D Munsell color solid
<>, which he
sent to the Z Corp engineers, so that he could point out the specific
bugs in the printer software.

The idiotic nature of this situation indicates to me that Z-Corp is
practicing some kind of intellectual protectionism -- reserving all R&D
for either Ellie Sachs at the MIT 3D Printing Lab, or Tim Alexander at
Z-Corp (but, I don't think so.)

The obvious improvement I would do right off would be to substitute the
cheap HP print heads with the Epson, color-fast, eight-color process
print heads and inks.

There has to be some kind of I-P tug-of-war going on between MIT and
Z-Corp which prevents things like this from happening.
