2 part 3-D print

3-d Manufacturing Description

Students will learn how 3-d objects are made, molded and cast by hand and manufactured. Students will Utilize software to make 3-d objects on the computer. Use a 3-D printer to manufacture those objects. Everything from artistic sculptures to mechanical parts will be made.

Outcomes:
  • Students will develop problem-solving skills
  • Students will develop their own 3-d objects and make clay prototypes
  • Students will make single and multi-piece molds of their clay objects
  • Students will cast their objects in resin or other materials
  • Students will use an injection mold machine
  • Students will make their own molds for the injection mold machine
  • Students will be introduced to industry-standard 3-d software and vocabulary
  • Students will understand elements of planning and design
  • Students will develop mechanical and artistic 3-d pieces on the computer
  • Students will utilize a 3-d printer to turn their computer files into real-life objects.
  • Students will make multi-piece prints that fit together for final assembly

    • Using CAD software, Students are to make at least two objects that fit together. These must be made from scratch, not with pre-made "connectors" or "shape generators" or "bricks".

    Some Examples:
  • 2 gears
  • Puzzle pieces
  • Clip and knuckle
  • Chain links
  • Axel and bearing and wheel


    • The teacher illustrates how to use negative shapes or "holes" to produce pieces that fit together perfectly.

    Students' work will be printed to proof the fit of each part.

    Evaluation:
    3 points -- Complexity (don't make it too simple)
    4 points -- Parts fit nicely (loose or tight according to application)
    3 points -- Printable (no closed hollows, nothing too thin, ect.
