3D Printing for Instruction

3D models produced on TLT’s MakerBot printer.

What is 3D Printing?

While there are several methods of 3D printing, Fused Deposition Modeling (FDM) is perhaps the most common in educational settings. FDM printers are similar to classic inkjet printers in that both have print heads that deposit material onto a medium. In the case of an inkjet printer, it’s ink on paper. For a FDM printer, it’s plastic on a print bed. Aside from the different print materials and media, the main difference is that 3D printers can go beyond the X and Y axes and are able to print upwards in thin layers, on the Z axis. This results in detailed, three-dimensional objects.

Our 3D Printer

TLT has a MakerBot 5th Generation Replicator to help faculty create models, manipulatives, and artifacts to enhance instruction. It uses Polylactic Acid (PLA) plastic which is made from cornstarch so it is both biodegradable and renewable. Click on the video below to see our printer in action!

Getting Started

Let’s say that you want to print a topographical map of downtown Charleston to help your students visualize elevation in relation to flooding. How do you get started? Well, we condensed our four-page 3D Printing Policy and procedures into five, easy steps listed below. If you have any questions or concerns, please contact tlt@cofc.edu.

Print Reference Sheet

There are several variables that affect print time and plastic use–most notably the size and resolution of your print. Click on the chart below to see the of an example of an actual print.

Resources

The design software and apps listed below are for experienced CAD users and are not supported by TLT. Please refer to the tutorials listed on the publishers’ websites for support.

Don’t forget to export 3D objects as .OBJ, .STL, or .THING files.
