Fiber does not adhere well to the part


  1. Ensure the plastic loaded in the machine is MarkForged nylon. 
  2. Ensure that the proper filament type is selected for the print. Different filament materials have different print settings.
  3. If the fiber is still not adhering well, or does not look like it is properly filling on the first layers you will need to re-adjust the fiber nozzle height. Please see the "Adjusting the height of the fiber nozzle" routine in the Mark One user guide section.
