The present disclosure is drawn to material sets for 3-dimensional printing, 3-dimensional printing systems, and 3-dimensional printed parts. A material set can include a powder bed material of composite particles including glass beads coated with polyamide-12 polymer. The composite particles can have an average particle size from 20 m to 200 m, and the polyamide-12 polymer can include greater than 80 meq/g carboxylic end groups and less than 40 meq/g amino end groups. The fusing agent can include an energy absorber capable of absorbing electromagnetic radiation to produce heat.

A system for depositing a composite filler material into a channel of a composite structure includes an end-effector configured to extrude a bead of the filler material into the channel. The filler material can comprise a first group of relatively long fibers, a second group of relatively short fibers and a resin. A drive system is configured to move the end-effector relative to the channel, and a position sensor is configured to detect the position of the bead relative to the channel. A controller is configured to operate the drive system in response to the detected position and to operate the end-effector to heat and compress the filler material so as to orient the longer fibers in a substantially longitudinal direction relative to the channel and the shorter fibers in substantially random directions relative to the channel when the bead is extruded into the channel.

Insulating molded part having an upper part and a bottom part. The upper part and bottom part are formed as an integral injection molded or die-cast part. Further, cavities, between the upper part and the bottom part, are arranged as chambers separated from one another in an air-tight manner and the upper part and the bottom part are formed in respective cuboid manners, and the upper part is offset in a diagonal direction in relation to the bottom part.

Insulated packaging is provided including an inner substrate and an outer substrate attached to the inner substrate to form an air gap therebetween. An expandable material including expandable microspheres is provided with the expandable material disposed between the inner substrate and the outer substrate. An adhesive material different than the expandable material is disposed between the inner substrate and the outer substrate to attach the inner substrate to the outer substrate. A method for forming the insulated packaging is also provided.

The invention relates to a composition that includes a polyolefin, hollow glass microspheres, a polar semicrystalline thermoplastic additive, and at least one of an impact modifier or a compatibilizer. Articles made from the composition, a method of making such an article by melt processing the composition, and the use of the composition are also disclosed.

Sports boot element comprising all or part of a wall designed to form at least part of a lateral and/or frontal and/or rear and/or lower wall of a sports boot, characterised in that all or part of its wall comprises a material (10) comprising a polymer (11) and a hollow microball (12) filler.

The present disclosure relates to a process for preparing of high thermal conductivity and high heat capacity oriented ultrahigh molecular weight polyethylene (UHMWPE) product. The process includes feeding UHMWPE through rollers to obtain a pre-laminate which is further hot stretched to obtain the oriented UHMWPE product having high thermal conductivity and high heat capacity. The temperature of stretching is maintained below the melt temperature of the UHMWPE throughout the entire process. There is also provided a high thermal conductivity and high heat capacity oriented UHMWPE product prepared by the process of the present disclosure. The oriented UHMWPE product is characterized in the axial thermal conductivity in the range of 70 to 200 W/mK, transverse direction thermal conductivity in the range of 0.022 to 0.045 W/mK and heat capacity in the range of 6 to 25 MJ/m.sup.3K.

A thermoplastic composite structure is produced by extruding a bead of composite material to a desired cross sectional shape. An extruder extrudes the polymer bead containing reinforcing fibers, using a low compression first extruder stage where the polymer is mixed and de-gassed, and a high compression second stage where the polymer is consolidated and extruded. The cross sectional profile of the polymer bead may be altered using a variable extruder gate.
