Compression

Subject Area: Engineering

Learning Objectives: Students will learn about the compression of different types of materials.

Materials Needed: One computer, one Micro or Micro+ 3D printer, at least three spools of 3D Ink in different materials and weights per 2-5 students.

Brief Description: Students will print out test models in different materials and measure their compression.

To Prepare: Students will need a computer that has the M3D software on it. We recommend one printer per every 2-5 students. The Micro or Micro+ 3D printer will need to be plugged into both the wall and the computer. Each printer will need to have a spool of 3D Ink feeding into the external port. A spool holder is also recommended.

If you need assistance with any of the above please see our guides at support.printm3d.com.

Lesson Plan:

1. Divide students into small groups. 2. Students will go online to https://www.thingiverse.com/thing:13601 and download the lattice cube. 3. Each group should print one cube in at least three different types of materials. 4. Once they have their models printed, students should place weights on the cubes and measure how much weight it takes to compress the model 1mm, 2mm, & 3mm.
