Apparatus, system and method of process monitoring and control in an additive manufacturing environment
Apparatuses, systems and methods capable of controlling an additive manufacturing print process on an additive manufacturing printer. The disclosed embodiments may include: a plurality of sensors capable of monitoring at least one of an input of print filament to a print head of the printer, and a temperature of a nozzle of the printer, as indicative of a state of the additive manufacturing print process; at least one processor associated with at least one controller and capable of receiving sensor data regarding the monitoring from the plurality of sensors, and comprising non-transitory computing code for applying to the sensor data at least one correct one of the state of the additive manufacturing print process; a comparator embedded in the non-transitory computing code for assessing a lack of compliance of the print process to the correct one of the state; and at least one modifying output of the at least one controller to revise the compliance of the print process to the correct one of the state.
1. A system capable of controlling an additive manufacturing print process on an additive manufacturing printer, comprising:
a plurality of sensors capable of monitoring at least a dependence between an input feed, including a feed rate, of print filament to a print head of the printer, a temperature of a nozzle of the additive manufacturing printer, and number of hours of use of the print head, as indicative of a state of the additive manufacturing print process;
at least one processor associated with at least one controller and capable of processing a print plan and receiving sensor data regarding the monitoring of the print plan from the plurality of sensors, and comprising non-transitory computing code for applying to the sensor data a correct one of the state of the additive manufacturing print process;
a comparator embedded in the non-transitory computing code for assessing an upcoming lack of compliance of the print process to the correct one of the state per the print plan via application by the controller of a coded checklist comprising correct states for each input to the sensors; and
at least one modifying output of the at least one controller to revise the compliance of the print process to the correct one of the state by modifying at least the dependence as dictated by the coded checklist.
2. The system of claim 1 , wherein the correct one of the state is a current state.
3. The system of claim 1 , wherein the correct one of the state is a future state.
4. The system of claim 1 , wherein the correct one of the state includes one or more tolerances for the print process.
5. The system of claim 4 , wherein the one or more tolerances comprise at least one of a melt temperature and a trace size.
6. The system of claim 1 , wherein the revision to the compliance comprises one of modifications to the print process or cessation of the print process.
7. The system of claim 1 , wherein the revision to the compliance comprises a modification due to a characteristic of the print filament or the temperature of the nozzle.
8. The system of claim 1 , wherein the plurality of sensors comprise one of: discrete sensors; line scanners; cameras; time of flight imagers; and parallel or combination implementations thereof.
9. The system of claim 1 , wherein the lack of compliance comprises at least one of an over- or under-temperature, a non-print, a crimping of the filament, and a catastrophic failure.
