摘要: The invention is directed to a process of manufacturing a three-dimensional object by—providing a support structure comprising polyvinyl alcohol (PVOH) to—depositing and solidifying a molten thermoplastic polymer on the support structure to form a three-dimensional preform characterized in that the support structure consists of a mixture of polyvinyl alcohol (PVOH) and at most 20% by weight of at least one plasticizer according to formula (I), (II) or (III): —R1-C(CH2—OH)3 (1); —[R1-C(CH2—OH)2CH2]2O (11); —(R1)C(CH2—OH)2CH2—O—CH2C(CH2—OH)C(R1)CH2—O—CH2 C(CH2—OH)2R1 (III). With R1=H, CH3, C2H5, C3H7, CH2OH. The support structure can be dissolved to from the three-dimensional object.

摘要: A process of manufacturing a three-dimensional object includes a step of depositing and solidifying molten polyvinyl alcohol to form a support structure; and a step of depositing and solidifying a molten thermoplastic polymer on the support structure to form a three-dimensional preform. The support structure has a mixture of at least 50% by weight of polyvinyl alcohol and at most 50% by weight of at least one polymer of polyvinyl butyral, polylactid acid, ethylene-vinylalcohol-vinylacetate terpolymer, vinyl acetate-vinyl pyrrolidone copolymer, acrylonitrile-butadiene-styrene terpolymer, polycaprolactone, vinyl acetate-vinyl caprolactame copolymer, and polyvinyl alcohol having a degree of hydrolysis DH of 30-65%. The support structure can be dissolved to form the three-dimensional object.
