Design Constraints
- Support a 1000 N central load with minimal deflection.
- Withstand a 1000 N off-center load and 100 Nm moment.
- Reduce mass from a 4000g baseline while increasing stiffness.
Key Engineering Takeaways
- Simulation vs. Reality: PETG flexibility led to higher displacement than SolidWorks predicted.
- Design for Manufacturing: Hollow sections required supports; solid design would improve accuracy.
- Material Selection: PLA offered better precision for small cross-sections than PETG.
- Trade-off Management: Balanced mass reduction with stiffness through iterative simulation.
