A method for manufacturing an artificial elastic implant for restorative and reconstructive surgery includes two casting steps performed in a casting mold. The mold has at least a cover that is optically and UV transparent. In a first step, a first layer of a first photo-curable material or of a second photo-curable material is cast while forming a meniscus. Using one of two photo masks, the mold is irradiated with UV light to cure the first layer. In a second step, a second layer of either the first or the second photo-curable material is cast onto the cured first layer while forming a meniscus. After irradiating the mold again with ultraviolet light, unhardened photo-curable material is removed from the product by dissolving in a suitable solvent. After additionally irradiating the product with UV light, the product is soaked, separated from the mold, placed in isopropyl alcohol and then vacuum dried.

PLA polymers that can be expanded into microporous articles having a node and fibril microstructure are provided. The fibrils contain PLA polymer chains oriented with the fibril axis. Additionally, the PLA polymers have an inherent viscosity greater than about 3.8 dL/g and a calculated molecular weight greater than about 150,000 g/mol. The PLA polymer article may be formed by bulk polymerization where the PLA bulk polymer is made into a preform that is subsequently expanded at temperatures above the glass transition temperature and below the melting point of the PLA polymer. In an alternate embodiment, a PLA polymer powder is lubricated, the lubricated polymer is subjected to pressure and compression to form a preform, and the preform is expanded to form a microporous article. Both the preform and the microporous article are formed at temperatures above the glass transition temperature and below the melting point of the PLA polymer.

A wagon (90b) Includes a plurality of horizontal support bars (91f). A separator roll (12b) is stocked while the horizontal support bar is inserted into a core of the separator roll (12b) around which core a separator is rolled. This can prevent deformation and roll misalignment of the stocked separator roll.

A cured elastomer golf ball component is made by heating an elastomer compound containing an ethylenically unsaturated elastomer, an ethylenically unsaturated monomer, and first and second free radical initiators to a first crosslinking temperature T.sub.1 in a compression mold and partially crosslinking the elastomer, then heating to a second crosslinking temperature T.sub.2 and curing the elastomer component of the golf ball. Either: (i) the first initiator has a half-life of about 0.2-5 minutes at T.sub.1, the second initiator has a half-life of about 0.2-5 minutes at T.sub.2, and T.sub.2 is higher T.sub.1 by at least about 30° C.; or (ii) the second initiator's one-minute half-life temperature is at least about 30° C. higher than the first initiator's one-minute half-life temperature, T.sub.1 is within about 20° C. of the first initiator's one-minute half-life temperature, and T.sub.2 is within about 20° C. of the second initiator's one-minute half-life temperature.

Methods for fabricating fiber-composite truss structures comprise a) individually molding multiple unit cells of a given size, and subsequently fusing them together in a repeating pattern, b) cross members are consolidated with longerons while maintaining continuity of fiber in the longerons, and c) compression-molded truss components are unioned to continuous fiber beams by means of mechanically interlocking joints.
