Abstract: A method of selective sintering additive manufacturing comprises employing a powder comprising composite particulates comprising a first thermoplastic polymer and a second thermoplastic polymer interspersed with each other. In a particular embodiment, the first thermoplastic polymer and second thermoplastic polymer have differing absorbance of the irradiation used to sinter the particles when performing the additive manufacturing method. The first and second thermoplastic polymer may be continuously intertwined in within the particles or one of the polymers may be a discontinuously dispersed in a continuous matrix of the other polymer.

Abstract: A method of additive manufacturing is comprised of providing a material comprised of a ethyl cellulose polymer having an ethoxy content of 43% to 52% by mass and a plasticizer. The material is heated and dispensed through a nozzle to form an extrudate deposited on a base. The base, nozzle or combination thereof is moved while dispensing the material so that there is horizontal displacement between the base and nozzle in a predetermined pattern to form an initial layer of the material on the base and successive layers of the material are adhered on the initial layer to form an additive manufactured part by repeating the aforementioned steps. The article formed of the ethyl cellulose polymer may be used in many applications such as those related to the pharmaceutical and food industries.

Abstract: A three-dimensionally printed article is comprised of a hydroxyethyl methylcellulose (HEMC) having a DS of 1.7 to 2.5 and an MS of at least 0.5, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxyethoxyl groups. The HEMC may advantageously be used as a support material when making a three-dimensionally printed article using a build material such as a different thermoplastic polymer such as a poly(acrylonitrile-butadiene-styrene), polylactic acid, polyethylene and polyprophylene. When the HEMC is a support material it may be easily removed from the build material by contacting the three dimensionally printed article with water, which may be at ambient temperatures and a pH that is neutral or close to neutral.

Abstract: A composition which is suitable for extrusion molding comprises a) a ceramic-forming material, and b) a cellulose derivative that has a median particle length of from 110 to 300 micrometers. Advantageously a cellulose ether is used that has been obtained by providing a moist cellulose derivative having a moisture content of from 35 to 90 percent, based on the total weight of the moist cellulose derivative, and drying-grinding the moist cellulose derivative in a gas-swept impact mill to a median particle length of from 110 to 300 micrometers.
