Can you change resolution for the Peopoly Phenom

I am new to the resin printing and using Chitubox for slicing. I just purchased the Peopoly Phenom and have good prints with the settings for .05 can I change the setting to .02 and if so do I need to change any of the other settings? Like the 12 s exposure and so on?

I’m not sure whether peopoly has recommended times for 0.02 and so on, but as with most MSLA printers, you should be able to find a combination that works at lower heights. Jumping from 0.05 to 0.02 on smaller machines I normally recommend about ~60-80% of the exposure time as the 0.05, though you might need to do some tests.

Good luck

The short answer is don’t print layer height 20um on MSLA printers and not just larger ones like Phenom. Stick with 50um. It is the best combination for resolution, speed, and print success rate.

The longer answer is that the 20um is the layer height and is a lousy indicator for resolution. Layer height affects o resolution on Z-axis but could have adverse effects on x/y resolution, which is determined by resin and panel. By printing at 20um, the effect of crosscuring (UV light curing previous layers while printing current layer) is much higher than at 50um, and that lowers x/y resolution. Also, your print time is increased by at least 70% as the exposure time does not reduce linearly with the reduction in the layer height. It is often a loss/loss proposition. Additionally, many resins do not resolve well under 30um, so you are unlikely to gain anything there. There is a reason why we only showed a 50um profile.

Some pros do make 70um or 80um profiles to speed up printing without losing much on z-resolution.

And your exposure time for initial layers is likely way off for 20um (too much time).
