Or, is it? If you can get a matched pair there is a very good chance of being able to make at least one good one out of them. Some models are tetchy about setup and print reliability so it is worth doing some homework first. There are plenty of cheap lemons that jam part way through a print (and with monotonous regularity). Educational ones tend to be able to tolerate a bit more abuse than the cheapest home print ones. People find them harder to use than expected and so give up... Find one that suffered that fate and you are onto a winner. A 3D printer is nowhere near as simple to use as an inkjet printer (although it is getting better). > Is it worth playing with any of these?

We keep a couple running for the local library. Most of the problems stem from user error allowing things to clog up or get out of alignment or simply failure to set it up right at the start of a print. If you have any engineering aptitude they are mostly not too hard to fix, but it does take time and patience. If you want one to use for a specific task then you might be better off buying one from new so that you know it hasn't been dropped. -- Martin Brown
