Abstract
A three-dimensional printed structure can include a photocurable resin, a sinterable material, and a plurality of elongated particles. The elongated particles are distributed within the printed structure. The elongated particles are shaped and distributed to promote porosity control (e.g., improved densification) within the structure.
Claims16
A printed structure, comprising:
- a three-dimensional printed structure comprising a photocurable resin, a sinterable material, and a plurality of elongated particles, the elongated particles being dispersed within the printed structure, the elongated particles being shaped and distributed to promote out-gassing of the printed structure during a burn-off step for the photocurable resin, the elongated particles configured to at least one of collapse or enter a glassy phase at a temperature above the burn-off step.
A green-state structure, comprising:
- an object comprising a photocurable resin, a sinterable material, and a plurality of elongated particles, the elongated particles being dispersed within the object, the elongated particles being shaped and distributed to promote outgassing of the object during a burn-off step for the photocurable resin, the elongated particles configured to at least one of collapse, shrink, or enter a glassy phase at a temperature above the burn-off step.
