Abstract: A method of additive manufacturing for creating an item, comprising (a) forming a flow bed (FB) comprising a flowing stream or layer of a carrier fluid and/or fillers; (b) depositing a layer of a precursor matrix fluid on top of the FB or below the FB to create an interface layer comprising a mixture of the precursor matrix fluid and fillers; (c) delivering a light beam patterned to a current layer of the item being added through the FB and into the interface layer to cure a portion of the interface layer in a shape of the current layer of the item being added; (d) moving the current layer of the item above or below the interface layer; and (e) repeating (c) and (d) for each successive layer of the item.

Abstract: A two-wavelength, single-camera imaging thermography system for in-situ temperature measurement of a target, comprising: a target light path inlet conduit for receiving a target light beam reflected from the target; a beam splitter installed in a splitter housing at a distal end of the target light path conduit, wherein the beam splitter divides the target light beam into a first light beam and a second light beam; a first light path conduit emanating from the splitter housing comprising a first aperture iris installed within the first light path conduit for aligning the first light beam; a first band pass filter installed within the first light path conduit for regulating the first light beam to a first wavelength ?1 and an optional half waveplate installed within the first light path conduit to modulate a polarization ratio of the first light beam of ?1 wavelength; a second light path conduit emanating from the splitter housing comprising a second aperture iris installed within the second light path conduit

Abstract: A system for single photon absorption based vat photopolymerization additive manufacturing with photoinhibition induced curb and photoexcitation induced cure (SPA2CurbCure), comprising: a build chamber; a two-wavelength projection irradiation unit delivering a patterned photo-curbing exposure mask and a patterned photo-curing exposure mask, respectively, to create a curing legion of initiating chemicals surrounded by a distribution of inhibiting species; wherein a curing light beam comprising light having a first wavelength and a curbing light beam comprising light having a second wavelength from the irradiation unit are manipulated into adjacent complementary exposures, combined by a dichroic beam splitter and collimated into a target resin material in the build chamber.
