Abstract: In some variations, a polymer-based microlattice structure includes a plurality of intersecting micro-truss structural elements each comprising a thermoset first polymer, and a continuous coating layer (with a second polymer) that substantially encapsulates each of the micro-truss structural elements, wherein the second polymer in the continuous coating layer bonds the thermoset first polymer to a substrate. The micro-truss structural elements preferably are architecturally ordered and the coating layer is uniformly distributed within the microlattice structure. The polymer coating layer may be present over the entire microlattice surface area, thereby increasing bond area to improve toughness. The microlattice structure may also have higher glass-transition temperature and chemical resistance, compared to a microlattice structure without the coating layer. Methods of forming a polymer-based microlattice structure are also disclosed.

Abstract: Systems and methods are provided for designing and fabricating contact-free support structures for overhang geometries of parts fabricated using electron beam additive manufacturing. One or more layers of un-melted metallic powder are disposed in an elongate gap between an upper horizontal surface of the support structure and a lower surface of the overhang geometry. The powder conducts heat from the overhang geometry to the support structure. The support structure acts as a heat sink to enhance heat transfer and reduce the temperature and severe thermal gradients due to poor thermal conductivity of metallic powders underneath the overhang. Because the support structure is minimally or not connected to the part, the support structure can be removed with minimal or no post-processing step.

Abstract: A method of manufacturing a three-dimensional object facilitates the removal of support material from the object. The method includes moving the object to a position opposite a microwave radiator and operating the microwave radiator to change the phase of the support material from solid to liquid. A controller either monitors the expiration of a predetermined time period or a temperature of the object to determine when the microwave radiator operation is terminated. The microwave radiation does not damage the object because the support material has a dielectric loss factor that is greater than the dielectric loss factor of the object.

Abstract: Plastisol compositions having a two-resin interpenetrating polymer network (IPN) are disclosed. The compositions begin with blocked isocyanate grafted acrylic polymer, blocked isocyanate urethane prepolymer, plasticizer, optionally pigment, and optionally thixotropic agent. When subjected to a thermal cure, the isocyanate groups on the acrylic polymer and urethane prepolymer both become unblocked and both react with the crosslinking agent to form an interpenetrating acrylic-polyurethane network. The two-resin IPN offers improved storage stability, hand-feel characteristics, and processing properties for textile printing among other uses. Preferably these plastisol compositions are essentially free of polyvinyl halides and phthalates restricted for regulatory reasons.
