Abstract: A three-dimensionally printed article comprises a build material and a support material, the support material comprising a hydroxypropyl methylcellulose having a DS of at least 1.0 and an MS of at least 0.6, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxypropoxyl groups. The support material can be removed from the build material by contacting the support material with water.

Abstract: The inventions is directed to a method for recovering support materials used in an additive manufacturing process. The method comprises exposing a precursor additive manufactured article comprised of a water soluble support polymer and an insoluble material to water. The water soluble support polymer is dissolved in the water. The remaining article is then removed from the water. The dissolved water soluble polymer is precipitated from the water. The precipitated polymer is separated from the water and any remaining water removed to recover the water soluble support polymer. The recovered water soluble support polymer may then be re-used to make further additive manufactured articles.

Abstract: A process for producing a water-soluble cellulose derivative of a reduced content of water-insoluble particles comprises the steps of a) reacting cellulose with an alkaline material to produce alkali cellulose, b) reacting the produced alkali cellulose with one or more derivatizing agents to produce a water-soluble cellulose derivative, c) washing the produced cellulose derivative with an aqueous liquid once or several times to provide a moist cellulose derivative having a water content of 25 to 85 percent, based on the total weight of the moist cellulose derivative, d) subjecting the moist cellulose derivative to homogenization to form the moist cellulose derivative to a paste, and e) pressing the paste through a filter of a pore size of up to 200 μm.

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.
