3D-PRINT-AIDED PRODUCT DEVELOPMENT OF A MECHANICAL DEVICE
Students worked on the design of a rather simple mechanical device such a vise or a hand drill and executed 3D-prints of the unfinished designed parts every now and then for visual aid.
- Period of implementation: 42 Hours
- Country where the practice was developed : Finland
- Provider of the practice : Salpaus Further Education - Lathi
- Targetg group: EQF level 5
How to implement the practice :
Teacher assigns to the students an exercise of a mechanical device of which parts are not too complicated to 3D-print.
Students design and 3D-model the device from scratch.
When several 3D-models prototypes of the device are available, students export them to a 3D-printing slicer. Notice temperature settings must be according with the 3D-printing filament material type. Monitoring the 3D-printer while working is recommended, at the very least the success of the full first layer.
The 3D-prints provide visual aid and can simulate assemblies with decent accuracy. Based on them product development is more clear and teamwork is easier.
In addition to having a deep understandig of the 3D-modelling programs, the teacher has to learn the correct use of the 3D-printer available and be able to solve personally/with service support common errors and difficulties of 3D-printing.
Main learning outcomes from the practice :
Students get familiar to the 3D-printing technology in the engineering and production aspects.
Needed/Suggested digital tools:
- - Mechanical 3D-modelling program
- - 3D-printing slicer
- The practice was carried: : Hybrid online/classroom
Critical points to shift towards STEM learning and solutions:
Nowadays 3D-printers can be available in any design office, so it is really advantageous for the students to have 3D-printing experience.
Positive aspects of participatory learning :
Students get 3D-printing experience.
Negative aspects of participatory learning:
Students may avoid 3D-printing just to get ready earlier.
Included green education (if any):
3D-printing has minimal material waste compared to machining technologies.
