Summary

This project will promote learning digital fabrication using the constructionist learning theory, providing students space to learn through open-ended project-based experiences and helping students understand the real world value of digital fabrication.

What You'll Need

Materials List 

3/8ӠDowel Rods

Size 64 Rubber Bands

Protractor

Computer with Internet Connection

Tinkercad Online 3D design application

3D printer with Computer Assisted Manufacturing (CAM) software

3D printer filament

Ruler

Digital Fabrication Equipment Details

 3D scanning and printing

Design Files attachment:

2 STL models for connectors to build triangular pyramid and cube

ConnectorCube.stl
ConnectorTriangularPyramid.stl

The Instructions

Step 1: Design and print 3D connectors

Build excitement by showing students examples of what the 3D printer can do while the machine prints a new object. The examples will be more than just static toys. Many 3D printers are formed from 3D printed parts, and seeing this application can help students think beyond sculptural 3D printing.

For Next Steps covering the 3D design and print prompts and instructions, see facilitation/procedure further documentation attachment.

Step 2: Engineering Design Cycle

Explain the Engineering Design Cycle and how each aspect of the activity fits into the cycle.

PROBLEM – Need a sturdy shelter to cover one person that can be quickly assembled and disassembled.

DESIGN – Determine what shapes will be used to construct your structure

BUILD – Construct a prototype structure with dowel rods and rubber bands

TEST – Test the structure to ensure you can fit inside, and it will not fall over.

IMPROVE – Measure, design and print couplers to replace rubber bands to create a structure that can be easily taken apart and reassembled

Step 3: Form groups and distribute materials

  • Split students into groups of 3-5.
  • Each group will receive 20-30 dowel rods and a handful of rubber bands.

Step 4: Demonstrate building basic structures

  1. Show participants how to connect dowel rods.
  2. First, take a rubber band and hook it over one dowel.
  3. Then, wrap the rubber band around a group of dowels.
  4. Once the group of dowels is snugly wrapped, hook the rubber band back over a single dowel.

Step 5: Group Build Challenge

Share activity prompt- use the rubber bands and dowel rods to build a structure large enough for a person to stand beneath.
