3D printers are all the rage right now. There are people creating small models out of them, building houses out of them, and most recently, a whole car (most of a car) was built using a 3D printer. I've been interested in them for the longest while, but only in the past few years have they become affordable enough to gain traction with the hobbyist crowd, like me. You can pick up a relatively good one for less than 200 pounds, and the best thing about that is you can immediately (once you get it up and running, of course), start printing upgrades for the printer which further improves the quality of future prints.
With the huge reduction in price, this now becomes available as a tool for education. Yes, some schools probably already had 3D printers. However, they were most likely the kind that cost thousands of pounds, and no one was allowed to use it, cos it cost thousands of pounds. Now, they cost hundreds, so depending on the school you're in, they are well within the budget of single departments. So they can now feature much more widely in school curricula, and as department clubs and enrichment programs. This is exactly what this post or series of posts is aimed at, as it is way more fun if the students taking part already have an interest, and don't have to worry about the pressures of mandetory assessments and grading.
So how and where can this feature in your subject?
