Step 1: Present students with an overview of what additive manufacturing is.

Step 1: Ask students to autonomously research the different additive manufacturing systems and take note of their main features.

Step 2: Ask students to provide a chart for every system found (the chart should be provided in advance and include: the name of the system, how the system works, how it is used by industry 4.0, what are the pros and cons at the industrial level).

Step 1: Divide the students into groups

Step 2: Ask groups to share the information found at the individual level and to prioritise the most used additive manufacturing systems.

Step 3: Ask groups to create a presentation for the different additive manufacturing systems.

Step 1: Ask students to discuss together as a whole group to create a list of additive manufacturing systems used by industry 4.0, describing their main features. The teacher guides the discussion and provides extra information if needed.

• K1 To describe what additive manufacturing is and how the different systems work

• K2 To recognise the advantages, opportunities and benefits of the different systems of Additive Manufacturing
