UPDATED JULY 24

Have you been thinking about 3D printing something for your classroom, lab, or just for fun but don’t know how to get started? There are a plethora of easy to use and inexpensive online services to help with that! Here are some we have found to help send you on your way to 3D printing bliss.

HOW CAN 3D PRINTING BE USED FOR  CLASS?
Here are a few ideas for how 3D printing could be used in class:
1. Anthropology or history faculty could use 3D printed artifacts for examination and discussion prompting.
2. Engineering students could print out inexpensive draft prototypes of their designs to demonstrate part reliability.
3. Instructors could print complex models of things like mathematical concepts, chemical compounds, topographic structures, city or architectural pieces for classroom demonstration and discussion.
4. Art students could produce printed art for class and shows.
5. Theater students could print costumes and set pieces.
6. Oceanography faculty could print a bathymetry dataset model to use for demonstrating current flow.
7. Culinary students could print out molds for food products for advanced presentation techniques.
8. Biology students could print cell structure, viruses, organs and other artifacts as a demonstration of their knowledge or for study aids.
9. Education students could design age-specific learning products to teach their future students.
10. Music students could use 3D printers for augmenting existing or creating new instruments as part of their thesis project.

PRINTABLE MATERIALS INCLUDE

• plastics: flexible, strong, detail, frosted, translucent, elastic
• metals: steel, sterling silver, brass, bronze, gold, platinum
• others: castable wax, sandstone, ceramics & more!

DESIGN CONSIDERATIONS

There are some important rules of thumb you will need to keep in mind when creating a 3D model. Always look for tutorials and tips from your printing service, as they will be able to best advise on the design for specific materials.
