Stereolithography is usually fine for evaluating product form, but the cured polymers aren't (usually) functional. Fused deposition systems (from Stratasys) produce functional parts from ABS, similar in strength and workability (for drilling/tapping holes, finishing surfaces, etc.) to injection molded parts.
