Charpy Impact Test Specimen (Charpy V-Notch)
Print Profile(1)
Description
A 3D printable Charpy V-notch impact test specimen designed according to the ISO 148 geometry. This set is ideal for educational purposes, laboratory demonstrations, and comparing the impact behavior of 3D-printed materials with different internal structures.
Features
- ✅ Designed according to ISO 148 specimen geometry
- ✅ Standard V-notch
- ✅ 10 specimens included
- ✅ Each specimen has a different infill percentage (10% to 100%)
- ✅ Ideal for demonstrating the influence of infill on impact strength
- ✅ No supports required
Included Models
The download contains 10 individual specimens, each with a predefined infill level:
- 10%
- 20%
- 30%
- 40%
- 50%
- 60%
- 70%
- 80%
- 90%
- 100%
This allows students and makers to directly compare how infill density affects fracture behavior and absorbed impact energy.
Printing Recommendations
- Material: PLA (recommended)
- Layer Height: 0.2 mm
- Supports: Not required
- Print orientation: Flat on the build plate
Different materials such as PLA, PETG, ABS, or ASA can also be used to compare the influence of material properties in addition to infill density.
Applications
- Materials Science
- Mechanical Engineering
- Engineering Education
- Laboratory Demonstrations
- Charpy Impact Testing
- 3D Printing Research
- STEM Education
Note
The specimens follow the ISO 148 geometry. While the geometry is standardized, the mechanical properties of FDM-printed specimens differ significantly from conventionally manufactured metal specimens. Therefore, the models are intended for educational purposes and comparative experiments.
The infill percentage on the print as seen in the image is not on the actual modell, as it might change its strength distibution
