description 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.
