Abstract: A liquid resin composition comprising: a first proportion of acryloyl morpholine monomers; a second proportion of a photoinitiator exhibiting photodissociation into reactive subspecies responsive to selective exposure to radiation within a spectrum, the reactive subspecies polymerizing the first proportion of acryloyl morpholine; a third proportion of a radiation blocker absorbing radiation within the spectrum to limit penetration depth of incident radiation within the spectrum in the liquid resin; a fourth proportion of a polymerization inhibitor limiting an average chain length of acryloyl morpholine polymer polymerized from the first proportion of acryloyl morpholine monomers; and a fifth proportion of a temperature-stabilizer increasing the heat-deflection temperature of acryloyl morpholine polymer polymerized from the first proportion of acryloyl morpholine monomers.

Abstract: An apparatus for hybrid manufacturing comprising a frame, a build plate that is adapted to move relative to the frame, a material pump that is adapted to pump one or more materials, a mixing head that is adapted to mix the one or more materials, a mixing hose that is in fluid communication with the material pump and the mixing head, a vacuum pump that is adapted to remove air from a mold, a vacuum hose that is in fluid communication with the vacuum pump and the mold, a vat that is adapted to retain a liquid, and a radiation source that is disposed adjacent to the vat. The apparatus prints the mold and fills the mold. A method comprising printing the mold with one or more mold materials, removing air from the mold, filling the mold with one or more primary materials, and dissolving the mold.
