Assignee: INKBIT, LLC
Field: Other special machines (Mechanical engineering)
Classification: CPC B  C | IPC B  C

Claim 0:
1. An apparatus for use in carrying out additive manufacturing of an object, said apparatus comprising:
an ink that comprises a material and an optical enhancement component, said material being capable of undergoing cationic polymerization in response to illumination thereof and comprising an epoxy functional group and a photoacid generator,
a platform upon which said object is fabricated,
a printer that receives said ink and deposits said ink on said platform,
a lamp that triggers curing of said material on said platform on a layer-by-layer basis,
a motion actuator that causes relative motion between said printer and said platform, and
a controller configured to carry out non-contact feedback control over said additive manufacturing based on non-contact inspection of said object during fabrication thereof while said ink is in a partially cured state and while said ink is curing, wherein said curing of said ink takes place only via cationic polymerization, whereby said object is cured only by cationic polymerization, and wherein said non-contact inspection comprises determining geometry of said partially-fabricated object.
