Abstract
An apparatus, a system, and a method for improvements in fused filament fabrication (FFF). Characteristics of a filament may be measured during production of the filament and the characteristics stored in a memory for retrieval by a 3D printer. The 3D printer adjusts print settings as necessary based on the measured characteristics, thereby resulting in better print quality.
Claims10
A method of producing a filament spool, the method comprising:
- extruding a filament and measuring a filament material characteristic of the filament exiting an extruder, wherein the filament material characteristic is ovality of the filament;
- winding the filament onto a spool marked with an indicium;
- and
- storing the filament material characteristic measured and linking to the indicium in a memory for retrieval by a 3D printer that modifies a print parameter based on the filament material characteristic.

A system for producing a print material filament, the system comprising:
- an extruder including a sensor to measure a characteristic of the print material filament exiting the extruder, wherein the characteristic is ovality of the print material filament;
- a spooler configured to wind the filament on a spool, the spool including an indicium;
- and
- a memory that stores the characteristic of the print material filament and the indicium and links the characteristic of the print material filament and the indicium for retrieval of the characteristic of the print material filament by a 3D printer, wherein the 3D printer is configured to modify a print parameter based on the characteristic of the print material filament.
