A polymer composition suitable for manufacturing of isotropic three-dimensional printed articles, the composition including: a matrix phase including a propylene-based polymer or copolymer; and a dispersed phase in the matrix phase, the dispersed phase including an ethylene-based copolymer having a C3-C12 comonomer, wherein the dispersed phase has a different composition than the matrix phase, wherein the matrix phase has a crystallization half-time of less than 60 minutes.

Polyolefins having improved dimensional stability in three-dimensional printing, articles formed therefrom, and methods thereof

Polymeric compositions may include one or more adjunct polymers selected from a group of an ionomer and a polar polymer; and an intelligent additive, wherein when exposed to the external stimuli, the intelligent additive triggers a color change in the polymeric composition. Polymer compositions may include a nonpolar matrix polymer; one or more adjuncts selected from the group of an ionomer, a polar polymer, a metal salt, or combinations thereof. Polymer compositions may also include an intelligent additive, wherein when exposed to the external stimuli, the intelligent additive triggers a color change in the polymeric composition, wherein after at least 17 hours of exposure to the external stimuli, the polymer composition exhibits a &#x394;E of at least 8 or more, maintaining the &#x394;E of at least 8 or more for at least 5 days after the exposure to external stimulus is ceased.
