Abstract
This article describes a method of in-situ process
monitoring in the digital light processing (DLP) 3D printer.
It is based on the continuous measurement of the adhesion force between printing surface and bottom of a liquid
resin bath. This method is suitable only for the bottom-up
DPL printers. Control system compares the force at the moment of unsticking of printed layer from the bottom of the
tank, when it has the largest value in printing cycle, with
theoretical value. Implementation of suggested algorithm
can make detection of faults during the printing process
possible.
