REMOVABLE SUPPORT MATERIAL FOR ADDITIVE MANUFACTURING

A support material for use in additive manufacturing includes greater than about 30 weight percent up to about 70 weight percent of a C12 to C18 fatty alcohol ethoxylate and about 30 weight percent to about 70 weight percent of a C16 to C22 fatty alcohol, a transition temperature measured as the tem...

Beschreibung
Zusammenfassung:	A support material for use in additive manufacturing includes greater than about 30 weight percent up to about 70 weight percent of a C12 to C18 fatty alcohol ethoxylate and about 30 weight percent to about 70 weight percent of a C16 to C22 fatty alcohol, a transition temperature measured as the temperature immediately before phase change, based on viscosity measurement, is less than about 65 °C. A system for additive manufacturing includes such a support material and a build material, the ratio of C12 to C18 fatty alcohol ethoxylate to C16 to C22 fatty alcohol is selected for property matching of the support material to the build material. A method of additive manufacturing includes providing such a system and printing via an inkjet printer the support material and the build material to provide a precursor to a three-dimensional printed article.
