ABSTRACT:
A process for molding plastic parts includes the steps of providing two or more colors of pigmented powder particles of thermoplastic material; casting the particles against a heated surface to form non-patterned layers of particles with voids therebetween; heating the layers to form color blended fused fringe zones between the particles which fill the voids to form a solid, multi-colored, three-dimensional article while each particle retains its discrete particle core which maintains each particle's central or original color concentration and which cores have discernible light transmissive properties.
