5 dollars for 236 cc (14.4 cubic inches) is actually pretty cheap. We pay ~$5 a cubic inch for our stratus (FDM) and We recently speced an Objet model whose model material is about 4.20, I think the Zcorp is a little cheaper 2.50 a cc but then you need resin... Were can you buy this stuff? Now the objet printer is interesting it uses an inkjet process to deposit a photopolymer and then UV cby ppeetteerr - General
We have a laser cutter at work and are told not to cut PVC, are there in other media that you know of?by ppeetteerr - General
First I want to start out by saying I don't mean this post to be inflammatory. I think Zach has contributed greatly to the project and that if he wants to leave and start his own company that's great. There are a few questions that need to be answered about his transition from a paid employ of RRRF to that of founder of Makerbot Industries. 1. There are several products in the RRRF store whoseby ppeetteerr - General

Laser cutting PVC is not advisable and I assume that expanded pvc would be the same. What are you planing on cutting you pcbs with?by ppeetteerr - Mechanics
I was wondering what the suggested tool (dremel, printer head, pin) mounting method for the laser cut Mcwire Cartesian bot was. Zach mentions something at the bottom of the assembly page. But I'm not really sure what he means. Should I just drill holes into the acrylic and mount to that?by ppeetteerr - Mechanics
I agree it probably would not be cost effective. Let's face it steel threaded rod is dirt cheap and pretty easy to use. But if one of the goals of the reprap is to have a 100% self replicating machine then it provides a means to do so. Instead of gluing the acrylic together you could screw it together (as done now in the laser cut version for the print head holder) or print it in sections and aby ppeetteerr - General
I noticed that there is a plethora of threaded rod on the reprap. If I understand this is to provide rigidity. Has anyone considered using a much larger polymeric tube? An example of this is a square acrylic tube of 20 mm width and height with a wall thickness of 3 mm could support the same as a 8mm diameter steel rod. The tube could be assembled by either printing it. Or if its a laser cut repsby ppeetteerr - General
