3D Printing Forum

ok... sooo... I really want to get into resin printing (already on FDM) but I am about to throw the towel. I got the Elegoo mars and after many prints never got any right, always sticking to the FEP. After many tries unfortunately I returned it and got the photon. (Thinking it may be defective) but Same problem. I’m wasting a lot of money on the overpriced FEP. Not even the test prints. (Test prints does not stick but don’t come out right) And yes. The plate is well tightened and I believe the Z axis is well set. Also is on a sturdy cabinet. Watched many YouTube videos and I’m doing everything “right”. Or not, but I can’t find the answer please someone help me is this resin printing that complicated? Thanks all

The part you are trying to print is very particular as it's very thin.
I had a few bad prints to start with but got my photon working.
It is different to FDM, you just need to know a few rules.
It the built plate level and set correctly.
Is the print orientated correctly for resin printing.
Are the setting for the resin correct, I had to increase the exposure time for the base layers a bit.
Below is a list of resins and setting.

I was having trouble with a Anycubic Maroon (red), it's a difficult one to use.
I now use Elegoo LCD ABS-like resin.
When I got a few good prints and found the correct set-up I have not had any problems, I've done 100's of prints.

Try something easy to start with, then build on that.
I use PrusaSlicer for orientation and supports and Chitubox for slicing. The software with the Photon is a bit basic, but it works.


I hope this helps.

Thanks a lot! I will try those settings

I've asked a friend who has this model printer to chime in .... hopefully he can offer some advice too

To start off what resin are you using and what settings? Is this the included pre-sliced test file or one you sliced yourself. Prints not sticking to the build plate is often due to not enough cure time or bad bed level/Z-height. Prints failing like your picture are often due to not enough cure time on standard layers, resin/ambient temp too cool, or lifting speed too fast. More information to start will help.
