TPUs are flexible filaments known for their elasticity. They are materials that can be stretched and bent easily. TPUs are popular in 3D printing because of their elasticity and ability to produce flexible, resilient objects.
Why TPU?
TPU filaments offer excellent inter-layer adhesion, favoring print quality, while their flexibility makes them ideal for prototypes, shoe soles and other components requiring resistance to deformation. They are also highly effective in terms of impact and wear resistance. This adaptability in 3D printing further broadens the scope of TPU applications, making it the material of choice for projects requiring both strength and flexibility. The degree of flexibility will depend on the hardness of the filament used, indicated in shore A.

Questions / Answers
Why is it important to adjust print speed when printing with TPU?
It's important to reduce printing speed, as TPU's flexibility can cause it to bend during rapid movements, leading to clogging in the extruder.
How does printing temperature affect TPU printing?
TPU has a unique melting temperature, so adjusting the printing temperature when switching to TPU is necessary to ensure correct melting and adhesion.
What do I need to bear in mind about the temperature of the building platform for TPU?
The tray temperature needs to be adjusted as different materials have different glass transition temperatures, which affects the way the TPU adheres to the tray.
What are the shrinkage parameter challenges for TPU?
Shrinkage requires careful adjustment with the TPU; too little shrinkage causes threads and too much can lead to clogging due to the filament's flexibility.
