摘要
Technologies are generally described for controlling fabrication of a 3D printed article by monitoring a temperature of an active growth region during a 3D printing of polymer material. A polymer material may be doped with one or more fluorescent molecules, which may be excited during a 3D printing of the polymer material. An intensity of light emitted from the fluorescent molecules may be determined to create a fluorescence intensity map, which may be converted into a temperature map in order to monitor a temperature of the active growth region, and generate one or more instructions based on the monitored temperature. One or more characteristics of the active growth region may then be modulated based on the instructions provided. Modulating characteristics of the active growth region based on the monitored temperature may allow better process control, which may be used to enhance a speed and resolution of 3D printing systems.
