Summary:

Elastomeric materials can provide increased heat resistance and flexibility to parts 3D printed by fused filament fabrication (FFF). There are a few points to consider when performing FFF with an elastomer, such as buckling of the filament, the amount of friction created within the system, avoiding curing the filament in the system, and ensuring adhesion between layers. Controlling the amount of friction in the system will prevent hang ups and buckling, if the filament is properly supported. The filament should also avoid being exposed to too much heat to prevent premature curing inside of the hot end. Once the rubber is extruded by the system, it is important that the extruded filament is encouraged to fuse with other layers before being cured.
