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. |
