A polymer bond abrasive article is formed of a continuous photocured polymer matrix having abrasive particles retained therein. The photocured polymer matrix includes at least one of an optical brightener or a light absorber, and the polymer bond abrasive article has a three-dimensional shape. An abrasive tool includes the abrasive article affixed to a shaft or a pad. Further, a method of making the polymer bond abrasive article includes a) obtaining a photocurable composition liquid dispersion; b) selectively curing a portion of the photocurable composition; and repeating steps a) and b) to form the polymer bond abrasive article. The dispersion contains at least one photocurable component; abrasive particles; a photoinitiator; and at least one of an optical brightener or a light absorber.

A particulate build material for three-dimensional printing can include from about 80 wt % to about 99.5 wt % of a polyamide particles, and from about 0.5 w % to about 7.5 wt % of thermally conductive particles including cubic lattice structured particles of carbon, cubic lattice structured particles of boron and nitrogen, or a combination thereof.

A fiber reinforced composite component may include interleaved textile layers and ceramic particle layers coated with matrix material. The fiber reinforced composite component may be fabricated by forming a fibrous preform and densifying the fibrous preform. The fibrous preform may be fabricated by forming a first ceramic particle layer over a first textile layer, disposing a second textile layer over the first ceramic particle layer, forming a second ceramic particle layer over the second textile layer, and disposing a third textile layer over the second ceramic particle layer.

A composition includes an infrared reflective additive having one or more infrared reflective colorants and a thermally emissive filler. The infrared reflective additive can be melt processed in a polymeric matrix.

A method of fabricating a polymer composite material by mixing a polymer material with a planar material, depositing the mixture on a substrate, and stretching the resulting thin film, is described. Polymer composite materials produced using said method and ballistic resistant materials comprising said polymer composite materials are also described.

Three-dimensional printing kits can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer build particles and cellulose particles. The cellulose particles can be chemically and thermally stable at a melting point temperature of the polymer build particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.

A heater for a cigarette-like electronic cigarette and a method of manufacturing the heater are provided. The heater is provided with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin.

A slurry composition for forming an article using additive manufacturing is provided. The slurry composition comprises a carrier having a viscosity of at least 0.001 cP at normal temperature and pressure. The carrier is adapted to be flowable through a nozzle. The slurry composition further comprises a material selected from the group of a metal-containing material, a ceramic-containing material, an inorganic carbon-containing material, a silica-containing material, and combinations thereof.
