I am investigating the benefits of a Rapid Prototyper vs a large CNC router and would invite peoples thoughts. I currently have a Rapid Prototyper but find it slow to produce pupils work ie leaving it running overnight. However, as we are lucky enough to have a new school built I am told I can 'exchange' equipment as long as it is to the same value as we are not allowed to take any over, Therefore I thought about getting a CNC router so I can machine work instead of using a laser to cut out plywood as it doesnt always cut through and leaves a charred edge. This would mean sacrificing the Rapid Prototyper but based on how slow it is to build products this may not be a bad thing. Oh yes, I teach Product Design KS3 & 4.
