3D printing-modern available technology of the future (LS-PL-105)

“3D printing-modern available technology of the future” lesson took place in the Complex of Technical Schools In Grudziądz, during the operation of machines and electrical devices – LAB in the 3rd class.


The role of the classes in conducting 3D printing consisted of presenting technical youth from high school with a wide range of modern vocational subjects. The learning scenario was implemented in a class of students aged 16 to 20 years old. To increase the attractiveness of lecture and laboratory activities, ICT techniques were used to introduce professional issues. In order to evaluate the students, models of various things, from simple elements such as a keyring to models of complicated mechanisms and human internal organs (ribs, hip, wrist) were presented. For this purpose, the Europeana portal and own materials related to the lessons from the teacher’s website were used.

3D printing with Europeana

In the first part of the course, Europeana was described to the students. The teacher explained how to use its resources and the basic functions of the platform were shown. Next, STEM and robotics items were found in the Europeana platform, using the search engine. These were various materials, ranging from the 3D printer construction through diagrams, to specific implementations in the industry, such as the Prusa i3 in modelling.

Programming together

In the second part of the class, the students and the teacher started programming together in the Repetier_Host program. The correct program code was saved and sent to the real 3D printer. Programming was carried out as 23 laboratory instruction from the teacher’s website.

In the third part, the students independently programmed the model environment. Then, they tested the program code and sent it to the 3D printer. In this part of the class, the teacher supervised the pupils’ work only. It reinforced the students’ independent, as well as their creative and innovative thinking. The teacher became only ‘an advisory voice’ and helped with some incomprehensible issues. The last task was for each student to create a report on the work carried out with the placement of the program code and the conclusions from the work.

After the lessons, the students learned or explored knowledge, such as:

  • STEM;
  • Vocabulary connected with the topics of mechatronics & robotics;
  • Cartesian system;
  • Use ICT tools.
