摘要：
A method for manufacturing a three-dimensional object includes steps of: a) providing a digital description of the object as a set of voxels； b) sequentially creating an actual set of voxels corresponding to the digital set of voxels； wherein at least one voxel comprises a composition comprising between about 35 and about 100 wt. % of a polymer selected from the group consisting of nonionic PEG homopolymers, PEG copolymers, and mixtures thereof； the polymer having an average molecular weight of between about 1,000 and about 95,000 AMU； and between about 0 and about 65 wt. % of a filler, wherein the filler is a solid at a temperature of above about 75 C, wherein the composition has a Melt Flow Index of between about 0.1 and about 50 g/10 min when measured at 70 C under a 1.2 kg load using a half-die according to ASTM D1238-13.
