The present invention is a composition for making a three-dimensional object. The composition comprises a plasticizer and a base polymer, where the base polymer comprises a carboxylic acid, where the composition is soluble in an alkaline solution.

Soluble material and process for three-dimensional modeling

The present invention is a method () for manufacturing a three-dimensional object. The method () includes receiving () digital information of the three-dimensional object over a communication line and building () the three-dimensional object based at least in part on the received digital information, where at least part of the three-dimensional object is built by rapid manufacturing, and where the three-dimensional object comprises an exterior surface. The method also includes vapor smoothing () at least a portion of the exterior surface of the three-dimensional object.

Transactional method for building three-dimensional objects

A process for three-dimensional modeling in which an alkali-soluble thermoplastic material is used in an additive deposition process to form a soluble support structure ( ) for a three-dimensional object ( ) under construction. The alkali-soluble thermoplastic material includes a base polymer of carboxylic acid and a plasticizer. Following formation, the object ( ) is placed in an alkaline bath to dissolve the support structure ( ). The alkali-soluble material can be used to form an alkali-soluble three-dimensional object ( ).

The present invention relates to a fibrous material which includes a plurality of polylactide containing fibers. The plurality of polylactide containing fibers can be considered low shrinkage or high shrinkage. The plurality of polylactide containing fibers are considered low shrinkage fibers if they provide a boiling water shrinkage propensity of less than about 20%. The plurality of polylactide containing fibers are considered high shrink fibers if they provide an average fiber boiling water shrinkage propensity of greater than about 10% and a heat of fusion of less than about 25 J/g. The invention additionally relates to the use of an extrusion process to provide low shrinkage fibers and high shrinkage fibers. The invention further relates to the use of these fibers in desirable products.
