Rubbery Prints - CMD1970 - 09-14-2022 Hey all, Coming here for some help as I am having an issue with my Elegoo Mars Pro. Lately all of my prints have been coming you like wet noodles. What I mean is that after they print I can bend them all over the place without breaking. This is pre curing of course but not normal. I have replaced the LCD, FEP, leveled and releveled, bought new resin (just in case of a bad batch). In addition, I have played with the exposure times and settings to try and see what I could find. Here is my findings. I Have to now increase my bottom exposure time to 70 and Exposure time to 16 to even get a file to print at all and they come out super soft. I am worried that my bulb/lens is going out. I looked at the light when doing the test and cannot really tell if it is dim or not. I don't have holes or blank spots and it doesn't look like it dims at any location. I have had the machine for 2 years and have used it somewhat frequently. I couldn't tell you the number of hours. I use ELEGOO 3D Printer Resin LCD UV-Curing Resin 405nm Standard Photopolymer Resin for LCD 3D Printing Translucent 1000g Any suggestions? Thanks for any help.

(I assume you are shaking the bottle well) The only time I've seen anything similar is when I was experimenting with dyeing the resin , excessive pigment/ink softened the resin. Can you see if all the all the UV LEDs are actually alight? (or the whole of the cob is alight, if single device) I suppose it could be the LEDs dying , they do have a finite life or maybe the driver is failing ? (anything obviously hot on the driver board?)

I have tried multiple bottles to see if the resin was bad but it is happening with both. To me it looks like the entire build surface lights up but I can't really tell if it is full strength. I have not noticed anything overly hot on the driver board but will check again. Not sure how much a replacement UV lamp costs and I can't seem to find one online either. RE: Rubbery Prints - billtodd - 09-16-2022 This might be a good one for Grant at 3dmusketeers.com and his youtube channel show called 'print fail Friday ' (he is genuinely a helpful and knowledgeable guy) What temperature is your print room/area? Cold ,i.e below 20'C can cause failed prints and so, I suppose, can very hot temperatures. Might be worth experimenting with an exposure test print like the 'test cones' (I'll have to look up the name) or similar. https://www.reddit.com/r/resinprinting/comments/sxyz8y/the_cones_of_calibration_from_tableflip_foundry/ RE: Rubbery Prints - billtodd - 09-17-2022 Another thought, Is there any chance you might have spilled resin onto the machine and it found its way onto the lens? Ut would only need a thin film to absorb a considerable amount of uv light RE: Rubbery Prints - CMD1970 - 09-27-2022 (09-16-2022, 11:58 AM)billtodd Wrote: This might be a good one for Grant at 3dmusketeers.com and his youtube channel show called 'print fail Friday ' (he is genuinely a helpful and knowledgeable guy)I will check out Grants channel thanks for the info. I have messed with the temp of the room and have made sure it was around 23-24'C/75'F. I am adding attachments of what the test exposure looks like for my bulbs just to see what you all think. Thanks again. (09-17-2022, 04:44 AM)billtodd Wrote: Another thought, Is there any chance you might have spilled resin onto the machine and it found its way onto the lens?
