TPU

Pros:

• Highly flexible and elastic: TPU is extremely bendable and can absorb shocks well, making it ideal for parts like bumpers, tires, or mounts that need to flex or cushion impacts.

• Excellent impact resistance: Unlike brittle materials, TPU can take hits without cracking or shattering, which is great for off-road or crash-prone RC environments.

• Good wear resistance: TPU holds up well against abrasion, so it's suitable for components that experience friction or repeated contact.

Cons:

• Challenging to print: TPU requires slower print speeds and fine-tuned settings to avoid issues like stringing or clogging. Not all printers handle flexible filaments well.

• Low structural rigidity: TPU is not suitable for load-bearing or structural parts. Its flexibility means it can deform under stress, which is a disadvantage for chassis or suspension arms.

• Moderate heat resistance: TPU can handle moderate temperatures (around 80–100°C), but it’s not ideal for parts near motors or electronics that get hot.
