Students of the second grade of primary schools. Primarily 6th and 7th graders.
Basic orientation and skills in the Tinkercad program. Available at www.tinkercad.com
For the actual printing of the 3D tool, the basic skill of operating a 3D printer is sufficient, such as preparing the mat (cleaning), inserting and removing the filament and starting the print from the attached .gcode files.
When using a different material or printer, knowledge of working with the PrusaSlicer program is required to prepare the .gcode file for the printer.
Alternatively, it is possible to use and modify the 3D models themselves in .stl format
Physics is generally an unpopular subject among students, but it is possible to get students excited about this important science through various experiments. For a better understanding of the principles and phenomena, it is necessary for the student to go through the entire experiment from the very beginning. Based on the information obtained, students will create their own shape of a boat with which they will continue to work and verify theoretical knowledge.
The goal of the project is to create an own didactic tool that will better demonstrate the experiment with the surface tension of liquids to students and the ease the understanding of this phenomenon through the experiment.
Thanks to the creation of their own experimental tools, students develop the following skills and competences:
3D printer
Account at www.tinkercad.com
Detergent (a common one for dishes or something similar)
Dropper or a syringe
Container filled with water
Internet access
100% scale, infill 15%, layer height 0,2 mm
| Name | Boat_(0-5)_0.2mm_PLA_MINI_1h7m.gcode |
| Description | Printing – 6 pcs of various boats |

For printing with standard PLA filament using Prusa printers, it is easiest to use the attached GCODE files.
The method of using the didactic tools in lesson is described in the attached presentations.
