makerbot - while the company that pioneered desktop 3d printing. Just aren't the brand they used to be.

Now one of the problems you will have putting a 3d printer in a school - is the health and safety.
I suspect you will need an enclosed print volume so that the kiddies don't burn their sticky little fingers poking the hot nozzle.

If I were you - and looking. I'd be looking at qidi.
As most of their printers are enclosed.
so machines to have alook at:
X-plus: https://www.amazon.com/Intelligent-I...s%2C699&sr=8-3

Or the slightly smaller x-pro - you could afford 2 of those :-) https://www.amazon.com/Function-Extr...s%2C699&sr=8-5

The makerbot sketch has a very small print volume: 150x150x150mm
The qidi x-pro by comparison is: 230x150x150mm
The x-plus is: 270x200x200mm

And if you really wanted to push the boat out and use the whole $1000 (well $977.50 anyway) the x-Max is:
300x250x300mm

All three are MUCH better machines that the makerbot. qidi has an excellent reputation for support, build quality and reliabuility.
And all their machines are fully enclosed.
