Personally, I opted to buy a Makerbot out of my own money rather than
have the school purchase it. This allows me to use it in various
settings. I've had students design small parts in Sketchup and upload
them to the 3D warehouse or Thingiverse.
Converting the files to code is a time-consuming process, often taking
at least 5-20 minutes per part. Another bottleneck in using it in
class is the build time. I ended up limiting the size of the part to
keep them around 20 minutes or so. About two parts per 70 minute
period was the best I got in the first semester using it with middle
school students.
In Sketchup, some of the resulting student designed files had design
problems and couldn't be built. There are ways that you can make extra
lines in your design or that faces of the object can be missing. These
flaws result in essentially blank gcode in Skeinforge. I ended up
going over each design by hand and clearing out the errors. This
further reduced the speed of turnaround.
That said, the students who designed and got their parts made were
very excited through the experience.
