Abstract
A system, method and computer program product for detecting filament jams and filament runout conditions on Fused Deposition Modeling (FDM) 3D printers, including a filament feed sensor configured to detect feeding of a filament by a filament drive motor and provide a feeding status thereof; a filament drive motor sensor configured to detect movement of the filament drive motor and provide a movement status thereof; and a processor configured to compare the feeding status and the movement status to detect at least one of a filament jam and filament runout condition on a Fused Deposition Modeling (FDM) 3D printer.
Claims18
A system for detecting filament jams and filament runout conditions on Fused Deposition Modeling (FDM) 3D printers, the system comprising:
- a filament feed sensor configured to detect feeding of a filament by a filament drive motor and provide a feeding status thereof;
- a filament drive motor sensor configured to detect movement of the filament drive motor and provide a movement status thereof;
- and
- a processor configured to compare the feeding status and the movement status to detect at least one of a filament jam and filament runout condition on a Fused Deposition Modeling (FDM) 3D printer.
A method for detecting filament jams and filament runout conditions on Fused Deposition Modeling (FDM) 3D printers, the method comprising:
- detecting with a filament feed sensor feeding of a filament by a filament drive motor and providing a feeding status thereof;
- detecting with a filament drive motor sensor movement of the filament drive motor and provide a movement status thereof;
- and
- comparing with a processor the feeding status and the movement status for detecting at least one of a filament jam and filament runout condition on a Fused Deposition Modeling (FDM) 3D printer.
A computer program product for detecting filament jams and filament runout conditions on Fused Deposition Modeling (FDM) 3D printers and including one or more computer readable instructions embedded on a tangible, non-transitory computer readable medium and configured to cause one or more computer processors to perform the steps of:
- detecting with a filament feed sensor feeding of a filament by a filament drive motor and providing a feeding status thereof;
- detecting with a filament drive motor sensor movement of the filament drive motor and provide a movement status thereof;
- and
- comparing with a processor the feeding status and the movement status for detecting at least one of a filament jam and filament runout condition on a Fused Deposition Modeling (FDM) 3D printer.
