Prompt: Today, we’re going to learn how to learn about 3D printing and create our own 3D keychain with our name on it. Here’s one that has been printed already [pass on the 3D printed keychain that you’ve printed in advance as an example].

Video: Show the 3D Printing video from the slides.

💡: Don't hesitate to briefly stop at key moments in the video to allow for students to react and integrate. Example: stop when you see the 3D printed shoes, "Wow! Does anybody want those shoes??"

Discussion: Ask the class about their feedback and any other object they’ll like to create.

Showcase: Gather everybody around the 3D Printer and explain the basis of how it works.

⚠️: Make sure to cover:

• Vocabulary: Filament (or food), Extruder, Printing Bed. (see full list in extra ressources TODO)
• What material is used: PLA, biodegradable. You can have the students touch the filament. For the Toybox 3D printer, it's called food.
• How the materials is deposited on the printing bed: filament placed layer by layer after being heated to 200°C via the Extruder.
• Highlight some of the challenges like Over-Hanging, etc.

💡: It'll be easier for students to grasp the 3D printing process if they is something printing while you showcase it.

Activity (35m)

Set-up: Send each student back to their computer and make sure they’re logged-in the Age of Makers Game.

Quest: This unit is linked to the first Quest of the Game in the 3D Valley.

Tips: You can use your own screen that you’re projecting with the game to guide the students.

Steps: The quest will guide the students to do those steps

• Login in Tinkercad using social provider Google

Warning: It’s important here to guide the students to log-in with their Google account and not create a new account. You can guide by sharing your screen.

• Follow the 4 Learning Modules from Tinkercad:
  • Learning the Moves
  • Learning the Camera
  • …
• Print their creations!

Wrap-up (5min)

Share: Call all the class attention, and ask to share some of their learnings & exciting aspect of designing in 3D.

Print: start a print for one of the students that have a finished design to show the students how their virtual design is becoming real.
