Abstract
Various implementations include a method of printing and curing of thermoset resin. The method includes outputting a thermoset resin from an outlet of a feeder and directing a stimulus from a stimulation source toward a portion of the output thermoset resin that is downstream from the outlet of the feeder. The stimulus is configured to heat the portion of the output thermoset resin to fully cure the portion of the output thermoset resin.
Claims21
A device for printing and curing of thermoset resin, the device comprising:
- a feeder having an outlet for outputting a thermoset resin;
- a stimulation source structured to direct a stimulus toward a portion of the output thermoset resin that is downstream from the feeder, wherein the stimulus is configured to heat the portion of the output thermoset resin to fully cure the portion of the output thermoset resin;
- and
- a computer numerical control (CNC) machine for moving the feeder and the stimulation source,
- wherein the device is configured such that a feed rate of output of thermoset resin from the outlet of the feeder and a movement speed of the CNC machine are determined as a function of a rate at which the thermoset resin fully cures and an amount of heat being added to the portion of the thermoset resin by the stimulus such that the outlet of the feeder remains a predetermined distance from a curing front of the output thermoset resin.
