Presentation of the teacher:

Step 1: Students get an overview of 3D printing systems like FDM printer, Resin Printer and Lasersinter machines and the most popular printers and its use in industry 4.0.

Step 2: Students get an overview of different slicing tools to produce G-Code and pictures for the printers to finally produce a 3D object out of a 3D design.

Step 3: Students summarise the most popular 3D printers and slicers and its use for industry 4.0.

Step 1: Teacher presents two popular slicers for FDM printing - Cura and Prusa Slicer (30 minutes)

Step 2: Teacher demonstrates the slicing with Cura with different settings (45 minutes)

Step 3: Teacher demonstrates the slicing with Prusa Slicer with different settings (45 minutes)

Step 4: Pupils get a stl. file and try to prepare a printing file by choosing either Cura or Prusa Slicer (3 hours)

Step 5: Teacher helps the students to get the file preparation right and sums up again what has to be taken into account before starting the print (1 hour)

Step 1: Teacher presents how to prepare a file for resin printing (30 minutes)

Step 2: Pupils prepare the files for resin print (2,5 hours)

Step 3: Teacher helps the students to get the file preparation right and sums up again what has to be taken into account before starting the print (1 hour)

Step 1: Pupils present their results and discuss the problems, difficulties, or smooth running of their file preparation (1 hour)

• S1 To prepare and manage the files for printing

• K3 To describe the sequence of process step

• K4 To describe how to prepare and manage the files for printing
