Abstract
The present disclosure describes a device used to determine the optimal post-curing exposure time for 3D printed products and methods of using the same. The disclosed device is a self-contained multi-chamber radiometer for continuous monitoring of electromagnetic radiation transmitted through 3D printed objects during a post-curing process. The device includes multiple detector ports, including a control port and one or more sample ports. The detector ports may preferably be photocells configured to generate a voltage proportional to the intensity of the incident electromagnetic radiation at specific wavelength(s). The transmittance is directly correlated with the voltage and may be measured using the determined voltages. The disclosed device may further comprise a microprocessor, a memory module for storage of data obtained by the sensors, and one or more communication modules configured to enable wireless communication with a data storage device such as a computer.
