摘要： A composition for three-dimension (3D) printing, a method for 3D printing, and a resulting article having porous structure are provided. Such a composition includes from 50% to 100% o by weight of a base polymer comprising polyolefin (such as ultra-high molecular weight polyethylene), from 0% to 50% by weight of a glue polymer (such as HDPE or PP), and optionally additive. A composition can be applied in a layer, and the base polymer and the glue polymer each has a predetermined size or size distribution. The composition is sintered in a selected area to form a layer of a solid article, which has a predetermined pore size or pore size distribution. The predetermined particle size or size distribution for each of the base polymer and the glue polymer is determined through computer simulation based on the predetermined pore size or pore size distribution in the layer of the solid article.

摘要： Disclosed herein are ethylene-based polymers generally characterized by a density from 0.89 to 0.93 g/cm3, a ratio of Mw/Mn from 3 to 6.5, a Mz from 200,000 to 650,000 g/mol, a CY-a parameter at 190° C. from 0.2 to 0.4, and a reverse short chain branching distribution. The ATREF profile of these polymers can have a high temperature peak from 92 to 102° C., and a low temperature peak from 18 to 36° C. less than that of the high temperature peak. These polymers can have comparable physical properties to that of a metallocene-catalyzed LLDPE, but with improved processability, shear thinning, and melt strength, and can be used in blown film and other end-use applications.
