3D printing is rather useful in the research lab. For example, most biological research labs will have a piece of kit called an electrophoresis chamber. This is essentially a plastic, watertight box with two wire electrodes inside. These chambers will cost upwards of 800 dollars.
By the way, does anybody know of similar services that are even less expensive? Shapeways seem to specialize in making little trinkets and gadgets, so I suspect my rather large, bulky box cost even more than it needed to.
I drew up plans for my own electrophoresis chamber in Sketchup, uploaded it to Shapeways (https://www.shapeways.com/model/1240729/sds-page-tank-v6.htm...), and got it printed and sent to me for less than 70 bucks. Wiring it up cost less than a dollar.
