摘要： Methods, systems, and/or apparatuses for making an object on a bottom-up stereolithography apparatus that includes a light source, a drive assembly, optionally a heater and/or cooler, and a controller. The light source, optional heater and/or cooler, and/or the drive assembly have at least one adjustable parameter that is adjustable by said controller. An example method comprises (a) installing a removable window cassette on said apparatus in a configuration through which said light source projects, said window cassette comprising an optically transparent member having a build surface on which an object can be produced, and with said optically transparent member having at least one thermal profile associated therewith; and then (b) modifying said at least one adjustable parameter by said controller based on said at least one thermal profile of said optically transparent member; and then (c) producing the object on said build surface from a light-polymerizable liquid by bottom-up stereolithography.

摘要： An improved method and apparatus for adding a new layer to a stack of previously processed layers. In an example, a method is provided for mounting the previously processed layer on a build platform, mounting the new layer on a substrate, aligning the new layer with the previously processed layer, moving the new layer and the previously processed into contact with one another, and applying energy to the new layer from an energy source through the substrate to simultaneously process the new layer and bond the new layer to the previously processed layer to form a bonded processed multilayer stack on the build platform. A flexible compliant pressure conveyance media is moved into contact with the substrate to apply pressure to the new layer while the energy is being applied.

摘要： Systems and methods for using a non-stick conductive material to automate tool touch-off in an additive manufacturing process are provided. A substrate comprises a first conductive layer, an intermediate binder layer, and a second non-stick conductive layer. The non-stick conductive layer may comprise perfluoroalkoxy alkanes and carbon nanotubes. An electrical connection may be made between the first conductive layer and the second non-stick conductive layer. When used with an additive manufacturing device, when the nozzle of the device contacts the substrate, a circuit may close resulting in a detectable voltage drop. When the voltage drop is detected, a reference point for the additive manufacturing device may be set.

摘要： An apparatus and method for shaping double-network hydrogels into customized 3D structures. A one-pot prepolymer formulation containing photo-cross-linkable acrylamide and thermoreversible sol-gel κ-carrageenan with a suitable crosslinker, and photo-initiator/absorbers was used. The formulation was polymerized using a TOPS system with heating stage to photo-polymerize the primary acrylamide network into a 3D structure above the sol-gel transition of κ-carrageenan (80° C.). Cooling down then generates the secondary physical κ-carrageenan network to realize tough double-network hydrogel structures. Printed 3D structures had superior lateral (37 μm) and vertical (180 μm) resolutions and 3D design freedoms (internal voids) that exhibit ultimate stress and strain of 200 kPa and 2400% respectively under tension, and simultaneously exhibit high compression stress of 15 MPa with a strain of 95%, both with high recovery rates. The apparatus and method can be employed with other double-network hydrogels to make multifunctional soft devices for a range of applications.
