Build material for forming a three dimensional article

摘要

The present invention provides a three-dimensional article formed from a build material comprising a solution of a resin having a hydroxyl number from about 5 to 1000 and a molecular weight greater than about 500, dissolved in at least one primary aromatic sulfonamide. The present invention also provides a method for making a three-dimensional article based upon article defining data. The method comprises the step of dispensing a meltable build material comprising a solution of a resin having a hydroxyl number from about 5 to 1000 and a molecular weight greater than about 500, dissolved in at least one primary aromatic sulfonamide in a plurality of droplets toward a platform and which solidify after dispensing to construct the article in successive layers based upon the three-dimensional coordinate data.
