I have been teaching for 29 years and knew nothing about 3d printers. A local business offered to buy one for my class. Obviously I could't pass up the opportunity.
On advice from a fellow teacher I went with the MakerBot. Although my knowledge and experience are limited I am extremely satisfied with how easy it was to setup and begin printing.
I am also impressed by the support and help I have received from the company. Not only have they answered all of my questions, they email and call to see how I am doing. At this point in my experience I don't know what more I could ask for.
