What this dot point is asking
CCEA Unit 3 expects you to know the new and emerging technologies changing engineering and manufacturing - robotics and automation, additive manufacturing (3D printing) and new materials and components - and to weigh their benefits and impacts.
The answer
Robotics and automation
Additive manufacturing (3D printing)
Additive manufacturing, or 3D printing, builds a part layer by layer from a CAD model, adding material rather than cutting it away. It can make complex and hollow shapes that are hard to machine, wastes very little material, and needs little setup, so it is excellent for rapid prototyping and one-off parts. It is usually slower than moulding for very large quantities.
New materials and components
Engineering also advances through new materials and components: stronger, lighter composites (such as carbon fibre), smart materials (such as shape memory alloys), and ever-smaller, cheaper electronic components and sensors. These let products be lighter, smarter and more capable than before.
Worked example: choosing an emerging technology
Examples in context
- Example 1. A car factory
- Welding and paint-spraying robots do the repetitive, hazardous work consistently and tirelessly, improving quality while reducing the number of manual workers.
- Example 2. A product prototype
- A designer 3D prints a complex housing overnight straight from CAD to test fit and form, far faster and cheaper than machining a one-off.
- Example 3. A modern appliance
- Smaller, cheaper sensors and electronic components plus lightweight composites let the product be lighter and smarter than earlier versions.
The pattern is that emerging technologies bring speed, accuracy and new capability, but raise issues of cost and employment that engineers must weigh.

Exam-style practice questions
Practice questions written in the style of CCEA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
CCEA style4 marksDescribe how robots are used in manufacturing and give one advantage and one disadvantage of using them on a production line.Show worked answer →
Robots are programmable machines used on production lines for repetitive tasks such as welding, spraying, assembly and moving parts (for example welding robots on a car line).
One advantage: they work accurately and consistently, fast and without tiring, and can do dangerous or dirty jobs safely, lowering labour cost over time.
One disadvantage: high cost to buy and program, and they cause job losses for manual workers; they are inflexible if the product changes often.
Markers reward a correct use of robots (named repetitive task) plus one valid advantage (consistency, speed, safety, no tiring) and one valid disadvantage (cost, job losses, inflexibility).
CCEA style3 marksExplain what additive manufacturing (3D printing) is and one situation where it is more useful than CNC machining.Show worked answer →
Additive manufacturing (3D printing) builds a part layer by layer from a CAD model, adding material rather than cutting it away. It can make complex shapes, including hollow or internal features, that would be hard to machine.
It is more useful than CNC machining for making a one-off prototype or a complex shape quickly and cheaply, because there is little setup and almost no wasted material, whereas CNC needs more setup and removes material as waste.
Markers reward the layer-by-layer adding description and one valid situation (rapid prototyping, complex/hollow shapes, one-offs, low waste).
