Vat for 3D printers handling high viscosity resins

A vat for a three-dimensional printer for handling high viscosity resin, the vat comprising:

• a first vat portion including a resin receiving space, and a piston member that is configured to push resin received in the resin receiving space upwardly through at least one hole formed in a cover portion;
• a second vat portion disposed on one side of the first vat portion and including a fabrication platform configured to support a structure fabricated using resin supplied from the first vat portion;
• and
• a blade portion configured to reciprocate between one side of the first and second vat portions and the other side of the first and second vat portions,
• wherein the blade portion includes a first blade and a second blade, the first and second blades including blade edge surfaces inclined at a predetermined non-vertical angle in a direction symmetrical to each other,
• wherein a digital light processing (DLP) focal length is fixed to a top surface of a wall disposed between the first vat portion and the second vat portion, and
• wherein the blade edge surfaces include a heating member extending along a longitudinal direction of the blade edge surfaces to heat said resin that is applied or recovered during a blading process of said blade portion.
