Student Learning Outcomes -
  • Select proper materials to construct simple models and forms and justify selections.
  • Create three-dimensional sketches by drafting simple primitives and applying proper line conventions.
  • Interpret and use industrial specifications and engineering standards for the safe selection and application of appropriate model making techniques and equipment.
Description -
Introduction to the principles of three-dimensional design as they relate to model making for 3D printing and rapid prototyping applications. Students will develop forms and shapes using a variety of materials and model-making techniques, with an emphasis on plastic and metal processes. In addition to modeling with basic materials, students begin to develop skills using quick, visual model-development materials, including foam core, cardboard and clay.

Course Objectives -
The student will be able to:
  1. Generate drafting designs of simple primitives including cubes, spheres, cones, and cylinders utilizing standard techniques.
  2. Select and apply proper line conventions to create three-dimensional sketches.
  3. Create thumbnail and concept sketches using various digital visual communication techniques.
  4. Interpret and use industrial specifications and engineering standards while completing laboratory case studies requiring selection and application of techniques and equipment.
  5. Select proper materials for optimum application and safely setup and use basic wood, metal, and plastic forming equipment to construct models.
  6. Build simple clay and plaster molds and develop quick shapes and forms by utilizing paper and plastic sheet materials.
