1. Description -
Focus on more advanced and complex methods used throughout the model-making industry. Students will develop skills in using computer-aided design and manufacturing equipment and software to fabricate models. Designs will be created on three-dimensional solid modeling software and transferred to a three-dimensional computer aided manufacturing software for coding and post processing. Students will fabricate parts on a variety of equipment which may include CNC mills and lathes, laser cutters, and two and three-dimensional rapid modeling equipment.
