Recycled Plastics & 3D Printing Workshop

Switch your perspective on plastics and waste and equip yourself with the practical skills and knowledge needed for a sustainable future. In this innovative fun, one-day workshop, you’ll learn how to process recyclable plastics and transform them into something new & useful, through shredding, molding, design and 3D printing. Designed to be accessible to everyone, the course explores plastic types, circular economy principles, and includes hands-on 3D printing activities.

Who Should Attend

- Makers, tinkerers, and DIY enthusiasts interested in sustainability
- Educators and students exploring recycling and digital fabrication
- Anyone curious about plastics, 3D printing, or the circular economy
Note: Participants aged 12–17 must be accompanied by a guardian.

Workshop Content

Understanding Plastics & the Circular Economy

- What are plastics?
- How plastics are classified and sorted
- Material properties and recyclability
- The role of plastics in a circular economy
- Activity: Sort plastic samples and test their recyclability

Plastic Processing Techniques

Explore key methods for transforming plastic waste:
- Shredding – breaking plastics into reusable flakes
- Extruding – melting plastic into filament or mouldable form
- Moulding – shaping melted plastics
- 3D Printing – turning filament into new objects

Activity: Operate a shredder, observe extrusion, and explore moulding firsthand.

Designing for a Circular Economy

- Cradle-to-cradle vs. cradle-to-grave: lifecycle thinking
- The role of product design in reuse and recycling
- Localised and small-scale approaches to plastic reuse
- Activity: Design, make, and take home a product from recycled plastic

Introduction to 3D Printing

- How 3D printers work
- Turning plastic waste into 3D printing filament
- Overview of slicing software and printer setup
- Activity: Prepare a simple print file and assist in a demo print

Making and Remaking: Real-World Applications

- What can be made from recycled plastics at home or in shared spaces
- Examples of open-source designs and community reuse
- Safety tips for home plastic processing
- Activity: Group discussion and Q&A with real-world recycled objects

What to Bring

- PPE: face mask and safety goggles (provided or bring your own)
- Lunch (or purchase from nearby cafés)
- Old clothes, closed-in shoes, and tied-back hair
- Avoid jewellery and loose accessories
