Flex Seal

The 3D printer flex seal is a teflon plate that is located at the bottom of the print head. Heated filament does not adhere to the teflon seal, so it ensures proper filament guidance and prevents filament from going in the wrong direction.

To ensure proper adhesion to the 3D print bed, it is advisable to clean the glass print bed before each print.The dddrop 3D printer bed cleaner is the recommended choice.
