To achieve digital light processing or DLP printing, start by using a DLP software. In the parameter settings, set the exposure time of the first single layer to the threshold time. Calculate the exposure time of curing 10 micrometer thick materials according to this equation and subtract the threshold time to obtain the real exposure time for curing a single layer.
In the software's parameter settings, set the time interval between adjacent layers to zero seconds. Start the printer by clicking the start button in the printing software. When the printing process ends, finish printing by clicking the stop button.
This protocol demonstrates that the continuous DLP printing method can accurately calculate the theoretical working curves of different materials. A high degree of coincidence was observed between theoretical predictions and real printing results for three distinct materials. Compared to the traditional DLP printing method, this method showed improvement in printing efficiency, with decreasing printing layer thickness.
Furthermore, a tenfold increase in curing efficiency was observed compared to traditional DLP printing, showing that the continuous DLP printing method can simultaneously achieve high efficiency and high fidelity.
