Hello printers!
I have a question about a setting for the exposure time of the first layers. So as far as I know you set the duration of exposure for the first few layers, then the exposure is shortened for all following layers.
Now, I have seen numerous posts on here by people who have printed their parts directly on the build plate, without supports, mentioning a clearly visible border of where the switch from long to short exposure happened. Mostly the suggested solution for this is to print with supports and the part lifted off the bed. But I have another idea and would like to know if you think it could work or if it may even already be implemented in some slicers.
In Slicers like Cura for FDM printing, print speed can be gradually increased from a slow speed at the first layer to faster speeds thereafter. I wonder if a similar approach would also help with DLP printers like the photon. Choosing long exposure for the first one or two layers and then a gradual decrease until the following short duration is reached. For example:
Layer 1 - 50s, 2 - 50s, 3 - 40s, 4 - 30s, 5 - 20s, 6 - 10s... n - 6s
Do you guys think this could work? Is this already a function that I can find in some slicers? Am I trying to reinvent the wheel and making a fool of myself? I'd very much value all your input.
Thanks a lot
:)
