I looked at Makerbot and was REALLY excited! Makerbot is essentially
like an open source project. Should you happen to be succesful in
printing and then burning out what you print, I THINK they encourage
you to share your knowledge with the community.
I was tempted because I love to tinker, however, I saw myself
tinkering and troubleshooting the process more than I saw myself
using it to make jewelry.
I did some research into what they print with. Essentially it is ABS
Plastic (Weedeater Line). Unfortunately that material would be a pain
to get a clean burnout with.
Perhaps that is why you only found a blurb.
Around $2000 for one of the machines completely assembled OR buy the
parts and build your own.
