A method for manufacturing a deflection member is disclosed. The method may include the step of incorporating a monomer, a photoinitiator system, a photoinhibitor, and/or a reinforcing member. A further step includes blending the monomer, photoinitiator, and/or photoinhibitor to form a blended photopolymer resin. Further steps may be emitting a first wavelength and emitting a second wavelength. A further step may be polymerizing the monomer to form a resinous framework comprising protuberance locked-on to the reinforcing member.

A process for producing an object from a precursor comprises the steps of: I) depositing a free-radically crosslinked resin atop a carrier to obtain a ply of a construction material joined to the carrier which corresponds to a first selected cross section of the precursor; II) depositing a free-radically crosslinked resin atop a previously applied ply of the construction material to obtain a further ply of the construction material which corresponds to a further selected cross section of the precursor and which is joined to the previously applied ply; III) repeating step II) until the precursor is formed; IV) treating the precursor obtained after step III) under conditions sufficient to at least partially trimerize to isocyanurate groups NCO groups present in the free-radically crosslinked resin of the obtained precursor to obtain the object.

Systems, methods, and devices to fabricate one or more device components are disclosed. An example method includes fabricating one or more subject specific device components generated from receiving one or more images of one or more features of the first eye of the subject; designing a three dimensional virtual geometric model of the ophthalmic device using the one or more images; generating a plurality of virtual cross-sections of the three-dimensional virtual geometric model, wherein the cross-sections are defined by a set of physical parameters derived from the three-dimensional model; and fabricating the one or more subject specific features using the plurality of virtual cross-sections of the three dimensional model to direct an additive manufacturing method.

Described is a high throughput machine for manufacture of large size 3D objects. The machine uses a combination of a large size main material dispensing head with a satellite lightweight material dispensing head. A motion system could move each material dispensing head along a path identical to the other dispensing head path or move it along a path different from the path of the other material dispensing head. Such complementary movement supports increase in machine throughput.

This invention relates to printable high strength/toughness polymerizable material systems for making dental products such as artificial teeth, dentures, splints, veneers, inlays, onlays, orthodontic appliances, aligners, copings, frame patterns, crowns and bridges and the like. A DLP, stereolithography, modified or their modification and combination based printer is used to cure polymerizable material in several different methods of this invention to build-up the object. The resulting three-dimensional object has good dimensional stability.
