One object is flexible whereas the second object is not, as the design for flexibility is based off of an individual who bends 🤸 but is being created in a 3D format.

When you want to make an object work with less flex, sometimes the only feedback you receive is that your object feels soft. Your object will function, as the geometry is correct, but when under load it bends too much compared to what was expected.

When you get to this point, the limits of PA12 have been met. The unique properties of PA12 make it a mid-performance material; however, this same performance level cannot be achieved in high-stiffness applications.

If the intent is to reduce the flex in your object, then the best option to use is usually PA12GB due to its properties:

• Higher stiffness
• Increased geometric stability
• Less deformation under load 🧱

In many cases, you may not need to create a new design – rather, you may need the right material.
