Patent number: 11117361Abstract: The present disclosure relates to a method for performing a three dimensional (3D) printing process. A primary light beam having a wavelength sufficient to initiate polymerization of a photoresin is generated and patterned into a patterned primary beam. The patterned primary beam is directed toward an ultraviolet (UV) or visible light sensitive photoresin to initiate polymerization of select areas of the photoresin. The photoresin is also illuminated with a secondary light beam having a wavelength of at least one of about 765 nm, 1064 nm, or 1273 nm. The secondary light beam stimulates triplet oxygen into singlet oxygen, which controls oxygen inhibition in additional areas bordering the select areas, to enable controlled polymerization inhibition in the additional areas bordering the select areas.Type: GrantFiled: April 9, 2020Date of Patent: September 14, 2021Assignee: Lawrence Livermore National Security, LLCInventors: Ryan Hensleigh, Eric B. Duoss

Patent number: 11072160Abstract: The present disclosure relates to a system for forming a three dimensional (3D) part. The system may incorporate a beam delivery subsystem for generating optical signals, and a mask subsystem that receives the optical signals and generates optical images therefrom. A first one of the optical images activates a polymerization species of a photo-sensitive resin in accordance with illuminated areas thereof, to thus cause polymerization of select portions of the photo-sensitive resin to help form a layer of the 3D part. A second one of the optical images causes stimulated emission depletion of subportions of the polymerization species, simultaneously, over various areas of the layer, to enhance resolution of at least one subportion of the select portions of the photo-sensitive resin.Type: GrantFiled: August 23, 2016Date of Patent: July 27, 2021Assignees: Lawrence Livermore National Security, LLC, The Regents Of The University Of CaliforniaInventors: Ryan Hensleigh, Bryan D. Moran, Julie A. Jackson, Eric Duoss, Brett Kelly, Maxim Shusteff, Hayden Taylor, Christopher Spadaccini
