Whether TPU is better than PLA or vice versa depends on the specific requirements of your project and the properties you are looking for in a 3D printer filament. Here are some key points to consider when comparing TPU and PLA:
Flexibility: TPU filament is known for its flexibility and elasticity, allowing for the production of objects that can bend and stretch without breaking. PLA filament, on the other hand, is a more rigid filament and lacks the same level of flexibility.
Impact resistance: TPU is generally more impact-resistant than PLA. TPU 3D printer filament can withstand impacts and deformation without cracking or breaking, making it suitable for applications that require durability and resilience.
Printability: PLA filament is generally considered easier to print with compared to TPU. PLA has a lower printing temperature, less warping, and requires fewer adjustments to the printer settings. TPU filament, on the other hand, requires more precise settings due to its flexible nature, making it more challenging to print with.
Strength: When it comes to tensile strength, PLA is typically stronger than TPU. PLA exhibits higher rigidity and can handle greater tensile forces before deforming or breaking. TPU, while not as strong, offers superior elongation at break, meaning it can stretch further before rupturing.
Ultimately, the choice between TPU and PLA depends on the specific requirements of your project. If you need flexibility, impact resistance, and durability, TPU filament is a better option. However, if you prioritize ease of printing and rigidity, PLA filament may be more suitable.
