Abstract: A method for processing a three-dimensional object formed by solid freeform fabrication from a build material having a polymer component to alter the appearance of the object. A fluid medium carrying an infiltration agent is applied to the object at a temperature above the glass transition temperature of the polymer component for a desired period of time wherein the infiltration agent penetrates the three-dimensional object. The infiltration agent can be a dye that can alter the color of the object.

Abstract: A chemically-amplified, negative-acting, radiation-sensitive photoresist composition that is developable in an alkaline medium, the photoresist comprising: a) a phenolic film-forming polymeric binder resin having ring bonded hydroxyl groups; b) a photoacid generator that forms an acid upon exposure to radiation, in an amount sufficient to initiate crosslinking of the film-forming binder resin; c) a crosslinking agent that forms a carbonium ion upon exposure to the acid from step b) generated by exposure to radiation, and which comprises an etherified aminoplast polymer or oligomer; d) a second crosslinking agent that forms a carbonium ion upon exposure to the acid from step b) generated by exposure to radiation, and which comprises either 1) a hydroxy substituted- or 2) a hydroxy C1-C4 alkyl substituted-C1-C12 alkyl phenol, wherein the total amount of the crosslinking agents from steps c) and d) is an effective crosslinking amount; and e) a photoresist solvent, and a process for producing a microelectro
