1. A 3D printing system, comprising:
a vertical conveyor having a plurality of folding build plates;
a plurality of biasing devices, a biasing device, of the plurality of biasing devices, being configured to rotate a folding build plate of the plurality of folding build plates from a folded position to a substantially horizontal position when the folding build plate enters a print chamber;
cams to cause the biasing device to rotate the folding build plate from the folded position to the substantially horizontal position when the folding build plate enters the print chamber; and
a 3D print head inside the print chamber adapted to 3D print an object on the folding build plate in the substantially horizontal position,
wherein the folding build plate is configured to rotate from the substantially horizontal position to the folded position when the folding build plate exits the print chamber, and
wherein the folding build plate, in the folded position, is configured to allow the object to slide off the folding build plate.
