3 d printer

[greg southerland]

This printer has the break away support material. I plan on making an offer this weekend and negotiating a price so i need to know how much we have promised please respond to myself or Roland with your pledge. My email is greg...@hotmail.com

Be sure to talk to someone who has experience operating one of those
printers before making the jump to buy it. Particularly about
sourcing plastic and support material (you can modify the machine to
use regular ABS plastic by emulating the chip in the cartridge), not
sure about the support material, which is PLA). The plastic costs
around $240/lb, and the support material slightly more. The support
material also requires a washing station, and a caustic chemical (lye)
to dissolve.

Also beware that the software required to drive them is
non-transferable (according to the license) and you may have to
repurchase it for thousands of dollars to stay within the legal bounds
of it.

They really arent much more capable than a modern makerbot. The parts
that come from a replicator 2 are almost indistinguishable from the
parts from a 1200. (we pass a part from each around when we do tours
of the hackerspace, and most visitors cant tell the difference) It
also prints significantly slower. The support material is about the
only good trick it has up its sleeve, but washing parts in the support
bath causes them to weaken, and be unable to handle any sort of
structural load. Think of it as a machine to make "models", not
"parts"

The 3d scanner is pretty cool! But beware of the same software
licensing issues. We are currently borrowing a nextengine 3d scanner,
and the software license costs as much as the hardware (around $3500+
for each), and the scanner has turned out to be minimally useful for
3d printing. Although its outstanding for any type of 3d modeling that
will remain on a computer, such as video games or 3d environments. If
you have a ton of experience with 3d modeling software, the scan can
get you a huge jump start, but they just require so damn much cleanup
that its not worth it without that skill. We have also found the
scanner to be useful for modeling parts that have to line up to other
parts. i.e. scanning the curve of a surface, so you can design a part
to fit that surface.

The is a break away support material the type that uses a bath. The polymer is expensive it is not a replacement for the printers we have it is for special parts requiring higher resolution. You don't run it for fun making keychains
