A method of fabricating an object from a heat curable polymer such as silicone is provided. The method is carried out by using additive manufacturing to fabricate a portion of a mold and filling the portion of the mold with the heat curable polymer. The polymer is then heated and the steps of mold fabrication and filling are repeated until the object is fabricated.

A method of making a thermoplastic gel prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an open proximal end, a closed distal end, and sidewalls comprising an inner layer of molded thermoplastic gel. The thermoplastic gel is molded over a mandrel that has been sandblasted using #36 grit and, optionally, #320 grit at 100 psi so as to form microcraters and reduce the coefficient of static friction.

A method including inserting into a mold a first tool having a first surface. The method further includes printing a second tool from a polymer material and inserting the second tool into the first tool. The second tool having a smaller wall thickness than the first tool and including a second surface opposing and in contact with the first surface of the first tool and a third surface formed on an opposite side of the second tool than the second surface.

Provided is a method for manufacturing a microneedle array, which enables efficient and stable manufacturing of a microneedle array including a needle-shaped protrusion having a constricted shape. The method for manufacturing a microneedle array includes: a first cutting step of forming a needle-shaped protrusion by cutting a base material by a first cutting tool; a second cutting step of forming a constricted shape in the needle-shaped protrusion by cutting a part of the needle-shaped protrusion by a second cutting tool different from the first cutting tool; a mold forming step of molding, from a plate precursor manufactured through the first cutting step and the second cutting step, a resin mold having a needle-shaped hole which has an inverted shape of the plate precursor; a first array manufacturing step of filling the needle-shaped hole of the resin mold with a drug solution and then drying the drug solution; a second array manufacturing step of filling the needle-shaped hole with a base material solution and drying the base material solution, after the first array manufacturing step; and a peeling step of peeling, from the resin mold, a microneedle array manufactured by the resin mold.

One embodiment is an apparatus including a mold configured to manufacture a composite structure at a heated temperature. The mold includes a first mold tool configured to mold a first portion of the composite structure, wherein the first mold tool comprises a plurality of strands of a fiber-reinforced thermoplastic material, wherein the fiber-reinforced thermoplastic material comprises a thermoplastic embedded with a plurality of reinforcement fibers, wherein the plurality of reinforcement fibers is aligned within each strand of the plurality of strands; and an anisotropic thermal expansion property, wherein the anisotropic thermal expansion property is based on an orientation of the plurality of reinforcement fibers within the first mold tool; and a second mold tool configured to mold a second portion of the composite structure.

A method for manufacturing a bowl and a glass bowl are disclosed. A high borosilicate glass bowl is manufactured with high borosilicate glass, which has characteristics of high hardness, high light transmittance, high chemical stability, cold and hot shock resistance, and the like. A radian of a bottom is measured by a laser scanner, so that an accurate molding die can be manufactured by a numerical control machine tool. A solid rubber compound is mixed by a mixing mill, and then a vulcanizing agent and a silica gel masterbatch are added to obtain a silicone rubber raw material. The silicone rubber raw material is taken out according to a preset weight, then put together with the high borosilicate glass bowl into a molding vulcanizer. Vulcanization compression molding is performed to obtain a high borosilicate glass bowl with an anti-slip silica gel bottom.

A method includes obtaining image(s) of a dental device, determining file(s) including at least one of a first model of the dental device or a second model of a mold, determining an intended property for the dental device based on at least one of the first model or the second model, and determining an actual property of the dental device from the image(s). The method further includes determining whether a cutline variation, an arch variation, and/or a bend of the dental device is detected between the dental device and the first model and/or the second model by comparing the intended property with the actual property. The method further includes determining whether there is a possible defect in the dental device based on whether the cutline variation exceeds a cutline variation threshold, the arch variation exceeds an arch variation threshold, and/or the bend exceeds a bend threshold.

A method of forming a model of a porous structure includes three dimensionally printing a mold of the porous structure using a polycaprolactone mold material, filling the mold with a polymer mixture, and heating the filled mold at a temperature above a melting temperature of the mold material to cure the polymer mixture, where the cured polymer mixture forms the model of the porous structure.
