TreeD's Flexmark series combines good printability with high flexibility. Thus, not only rubber-like objects can be printed, but you can also create almost indestructible components with it.

The lower the specified Shore hardness number, the more flexible the material. However, as the flexibility increases, the printability also deteriorates. Nevertheless, even the TreeD Flexmark 7 can still be printed well with a little experience.

• Mark7 = 70 Shore A, the most flexible, but requires the printer to be perfectly calibrated.
• Mark8 = 80 Shore A, a good mix of flexibility and stiffness that's also easier to print.
• Mark9 = 90 Shore A is the stiffest of all flexes and allows printing as usual.
