Methods for manufacturing three-dimensional objects using an additive manufacturing technique, methods for forming dye-infused feed material for an additive manufacturing technique, and vehicles including additive manufactured components are provided. An exemplary method for manufacturing a three-dimensional object using an additive manufacturing technique includes solubilizing a dye into a medium in the form of a supercritical fluid and contacting a feed material with the medium to infuse the dye into the feed material to form dye-infused feed material. The method further includes locally melting the dye-infused feed material in selected regions of a layer corresponding to a cross-section of a three-dimensional object being formed and solidifying the dye-infused feed material into a solid layer of dye-infused material. Further, the method includes repeating the local melting and solidifying steps to form the three-dimensional object made up of a plurality of solid layers of dye-infused material.

The laminated film is characterized by: the base film being a semi-aromatic polyamide film that has been at least uniaxially stretched; the resin layer containing fine particles; the thermal shrinkage factor in the longitudinal direction S.sub.MD and the thermal shrinkage factor in the width direction S.sub.TD of the film measured under conditions of 250 C.5 minutes each being 1.0 to 1.5%; the tensile elongations at break in the longitudinal direction and in the width direction each being 70% or more; and the haze being 3% or less.

Methods and systems are provided for forming a molded foam article. An example method may include molding a plurality of separate pieces of closed-cell foam by exposure to a temperature cycle within a sealed mold to soften the plurality of pieces sufficiently for physical bonding; and forming a molded foam article with the pieces bonded together without an adhesive, wherein, during the temperature cycle, the mold is unsealed at least once to release gases and/or pressure. In another example, a method includes exposing a filled, sealed mold filled with a plurality of pieces of foamed material to a heating cycle; at a threshold temperature, unsealing the filled, sealed mold until a pressure reduces to within a threshold of atmospheric pressure; and, following the unsealing, cooling the filled mold prior to removing a molded foam article.

This document discloses a process for manufacturing recyclable injection molded microcellular foams for use in, footwear components, seating components, protective gear components, and watersport accessories. The process includes the steps of providing a thermoplastic polymer which comprises at least one monomer derived from depolymerized post-consumer plastic, inserting a fluid into a barrel of a molding apparatus. The fluid is introduced under temperature and pressure conditions to produce a super critical fluid. The process further includes mixing the thermoplastic polymer and super critical fluid so as to create a single phase solution, and injecting the single phase solution into a mold of an injection molding machine under gas counter pressure. The process further includes foaming the single phase solution by controlling the head and temperature conditions within the mold.

A conveyor roller tube (1) including a plurality of co-extruded polymer layers (2, 3). The tube (1) includes an inner layer (2) and an outer layer (3), and an optional intermediate layer. The inner layer (2) is formed of a first polymer material. The outer layer (3) is formed of a second polymer material. The outer layer is formed to have high wear properties and is also formed to be of a different color to the adjacent layer (2) thereto so that a visual indication of the wear of the roller tube (1) is provided.

The present invention relates to a process for producing a shaped body by selective laser sintering of a sinter powder (SP). The sinter powder (SP) comprises at least one semicrystalline polyamide, at least one nylon-6I/6T and at least one polyaryl ether. The present invention further relates to a shaped body obtainable by the process of the invention and to the use of a polyaryl ether in a sinter powder (SP) for broadening the sintering window (W.sub.SP) of the sinter powder (SP).

A method for preparing a bionylon having triple shape memory effects comprises generating amino acid containing a biomass-derived pyrrolidone group using itaconic acid and a diamine; and generating a nylon copolymer by reacting the amino acid containing the pyrrolidone group and an ,-aliphatic amino acid. The prepared bionylon has triple shape memory effects and is capable of shape deformation, fixing and recovery through two steps. Shape recovery temperature can be adjusted to a desired level by controlling the content of a reactant.
