I found that they already do make a 3d printer for wood, it's a spoogy plastic/mdf mix.
They're even developing a 3d printhead for my cnc machine. It'll work with plastic, mainly to repair mistakes in substrate that will save a fortune for fixing goofs. Up till now, if you make a bad cut or have a crash, a $300 piece of material goes in the garbage.
I enjoyed the
Burritobot. Yes, a 3d burrito printer.
