Lesson Plan

• Describe the principle and key steps of each redistribution manufacturing method.
• Compare the advantages, disadvantages and typical applications of the eight processes.
• Evaluate which process best suits a given design brief using material, geometry, volume and cost criteria.
• Apply selection criteria to propose an appropriate manufacturing route for a sample product.

• Projector and screen
• Whiteboard and markers
• Handouts with process comparison table
• Sample material specimens (sand, resin, metal alloy chips)
• Short video clips of each process
• Worksheets for group analysis
• Access to a 3‑D printer (optional demonstration)
• Safety goggles for handling specimens

Begin with a quick poll: “Which manufacturing process do you think is best for making a complex metal bracket and why?” Connect this to prior lessons on material properties and product design. Explain that today’s success criteria are to identify the key steps of eight redistribution methods, compare their strengths and limits, and justify a process choice for a design brief.

1. Do‑now (5') – short quiz on casting vs moulding concepts.
2. Mini‑lecture with slides (10') – overview of the eight redistribution methods and their key steps.
3. Group activity (15') – each group creates a flow‑diagram poster for an assigned method.
4. Gallery walk & peer feedback (10') – groups present, discuss advantages/disadvantages.
5. Whole‑class synthesis (10') – fill in the comparison chart on the board, highlight selection criteria.
6. Exit ticket (5') – write which process you would choose for a given product and justify in two sentences.

Summarise the key take‑aways: each method’s principle, typical materials, and where it excels or falls short. Collect exit tickets to gauge understanding and assign homework: research a real‑world product, identify its manufacturing route, and write a brief justification linking the product’s requirements to the process selected.
