It's not market share i'm thinking about..Tought i belive that 3d printers will be bigger than microwave..
My thoughts is only around the possibillities.
For an example.: I dropped my butterknife on the floor.. The dischmachine is full and your girlfriend is on the run..
No problem. Just press the button.
There is examples where budgetprinters makes parts thats glued together.
And..To do crazy triggers should'nt be a problem for todays cheap printers..
