Re: Now this is more like it.
Not really. The cutlery set is only a part of the equation.
The difference between this uni project and a real 3D metal printer (one which you can actually use to print a gun barrel) is that you enclose the whole rig in an inert atmosphere. As anyone who has done some welding can testifiy a weld (regardless how good it is) always absorbs oxygen making its mechanical quality nowhere near that of solid metal. In other words - while it may "print" a sprocket, I am not putting that sprocket in my car any time soon as it will last only a couple of miles :)
So you need to add to it the argon bottles, pressurisation equipment, etc. You also need to make the whole rig tunable to accommodate for the infinite variety of "cutlery" sets you chuck into as well as detect what cutlery set was chucked in in the first place. That is rather difficult so you are likely to end up using pre-mixed pellets with appropriate flux and other additives mixed in too. That will not be 99p any time soon.
