Amazing elongation at break and impact strength for a wide variety of prototyping, functional testing and low volume production applications. This durable and flexible material produces the toughest 3D printed parts with the look and feel of molded polypropylene.

FabPro Flexible BLK is a flexible and exceptionally durable material that allows the production of polypropylene-like parts with amazing elongation at break and impact strength. In fact, in unnotched Izod impact strength testing to ATSM standards, the FabPro Flexible BLK material did not break. With FabPro’s accuracy, this robust material provides outstanding flexibility for a wider variety of prototyping, functional testing and low volume production applications.

Note: FabPro Flexible BLK requires 3D Sprint 2.11 or higher. A software database update is also required with 3D Sprint 2.11 and can be downloaded here. Additional information on this material is in the Customer information bulletin found here.
