Mark,
The Dimension 1200 is an FDM machine, not an SLA, apples and oranges. If you wan't SLA quality and finishes, use an SLA machine.
Don't judge the quality of "hobbyist" based on that machine at the lab. It is poorly adjusted, badly maintained and based on a design and tech that is several generations old. I got to see a lot of prints from modern makerbots and others at the makerfaire and, frankly, I can't imagine that FDM prints could get much better than those, even if they were to be done on "professional quality" machines.
Greg,
Even assuming there are no software or contract licensing issues from the manufactuer, there is still the problem of operating costs.
Sure, we could save money by using the cartridge refilling hack you posted, but did you read thorough it? It looks like a lot of trouble to go through just to circumvent a "feature" that shouldn't be there in the first place. Besides, I've read that even with that hack you can't use the cheap filament without lots of clogs, you have to buy better quality, more expensive stuff. Is it still a "professional quality" machine if we have to hack it to make it useful?
Further, the filament isn't the only consumable, the build tables are also consumables and have to be replaced regularly, if not every print.
I'm thinking that, for the price, we'd be better served with a MakerBot Replicator 2X (for FDM) and a Form1 (for SLA). There's also the idealogical advantage of supporting a company (MakerBot) that was itself started from a hackerspace.
Don't get stuck thinking that just because something is big, shiny, expensive, and "professional" looking that it is really worth the cost.
