Step 1: Present the students with an overview of the quality standards and indicators of the additive manufacturing products; maintenance indicators and diagnostic techniques and the more appropriate printing material for the specific 3D printer to the specific field of application.

Step 1: The teacher presents to the students how to prepare and set up the specific additive manufacturing system, which materials have to be used, do’s and dont’s and how to do the calibration and change of filament, etc (1 hour)

Step 2: Guide the students in setting up the printer. The teacher will guide the process by following the steps below, i.e. setting up bed leveling and axis travel, setting up coordinate origin positioning, extruder control, and loading the print material. (4 hours)

Step 3: Ask students to share any difficulties encountered during the activity. The teacher will guide the discussion and will provide useful tips if needed. (1 hour)

Step 1: At least one Ultimaker and one Prusa Printer have to be organized

Step 2: Each student should have the possibility to start a print by himself, transfer files to the printer (SD Card, USB Stick, WLAN ), change the material of the printer, do the calibration, check the smooth running of the print and remove his print on both printers - so everyone can do the whole process of starting and removing a print. (11 hours)

Step 3: Presentation and discussion on the results - difficulties, problems, what went well, what did not work (1 hour)

Step 1: Teacher presents the preparation of a resin printer and explains the materials used and the do’s and dont’s (1 hour)

Step 2: Students sum up and describe what they learned (30 minutes)

Step 1: At least one Resin Printer should be organized

Step 2: Each student should have the possibility to start a print by himself and clean the printed object and the printer after the print (11 hours)

Step 3: Presentation and discussion on the results - difficulties, problems, what went well, what did not work (1 hour)

Step 1: Students share their results and their learning with each other (1 hour).
