Abstract:
A binder, and a method of using it in conventional powder metallurgy processes and solid free form fabrication including metal powder, or combinations of metals and ceramics, in which the binder contains at least one carbohydrate as the active binding compound. The carbohydrate generally contains between 6 and about 900 carbon atoms and may be selected from various categories including but not limited to: 1) monosaccharides; 2) disaccharides; 3) trisaccharides; and 4) polysaccharides containing the base sugars identified in 1)-3) above; and 5) hydrolyzed starches in which the hydrolysate contains between about 6-900 carbon atoms, including dextrins such as limit dextrin, hydrolyzed amylose, and hydrolyzed amylopectin. The amount of carbohydrate in the binder solution is generally on the order of about 5-50 grams carbohydrate per 100 ml of carrier solution, more preferably 5-30 g/ml, and most preferably 15 g/ml (or comparable amounts on a dry basis).
