Summary

This activity includes a “hands on” strategy that mixes the use of two different digital fabrication tools (laser cut and 3D printing) and silicon mold, to produce replicas of animals threatened with extinction. The activity explored in this lesson raises students’ awareness about animal conservation and preservation.

 

 

What You'll Need

Materials for 5 turtles:

  1. A 3D Printer (FDM);
  2. PLA or ABS: aprox.200g;
  3. White or Blue Silicon: 1.250kg;
  4. Cardboard (Thickness = 1mm): a 540 x 300mm sheet for each kind;
  5. Play dough: 45g for each shell.

 

The Instructions

FDM 3D print the five different kinds of turtle shells;

Using a FDM 3DPrinter, print the 5 turtle shells, in PLA or ABS, any color and the two guides (a cross shape), one for the body and the other for the play dough shell.

Make a paper or mdf box that fits each kind of shell;

Using a simple paper (300g) ou 3mm MDF make boxes that can fit each shell individually.

Make a silicon mold from each kind;

Place each shell in the box and fill it out with blue or white silicon, occupying the whole box.
