No wondering 3d printers price started to come down. there is more
people out there trying to figure out how to make one.
Dimension is about to releasy a 9.999 one.
But the build material is still cost alot.
I had a quote for a FDM machine and the starting build material kit
was something like 3K.
It's about 200 bucks for 1Kg of build material.
well, the last time I had to buy a regular printer cartridge for my
lexmark it cost me about the same as a new printer, the 3d printer
makers are heading the same way.
