Introduction
The ESA Teach with Space Online Training – 3D design in education with Tinkercad. 19 and 26 Jajn 2022. 16h30 - 18h30 CET.
Catia Cardoso
Materials and processes for space. Challenges for space materials and procesesses.
- Low mass (when launched from Earth)
- Small production series
- Very high reliability
- Limited manufacturing processes (automation)
- Small to large geometries
- Very high performances
- Challenging material procurement
- On-demand manufacturing (exploration, repair)
- Efficient use of material.
Additive manufacturing: 3d CAD model, slicing, layer-wise assembly, complete part
- No tool
- Design freedom: any shape is possible(?)
- Many materials can be used
Not that simple
- End-to-end process: several steps
- Design: Design limitations (angles, overhangs, thin walls). Need for support structures
- Material supply: Powder is not perfect. Contamination: effect all the way to the end product
- Processing
- Post processing: Surface polishing, cleaning.Heat treatment to improve strength, remove defects
- Testing/ qualification
- Challenges at every step
What can it do for us
- Lower mass: put material only where is is needed.
- Fewer parts: less manufacturing steps
- Very large parts
