Basically I am getting voids in what should be solid prints. Thin outer edges of the print are printed but sections of the interior that should be solid are completely empty, leading to a failed print. This seems to occur sporadiacally and it doesn’t depend on the geometry of the print file because sometimes the same files will print successfully. I’m not sure if it tends to occur more in a particular part of the build volume.
I have been using clear resin V4. I don’t know if the issue occurs with other resins, I haven’t tried. I haven’t tried all the standard troubleshooting steps yet, so apologies if this post is considered to be premature - I just wanted to check if others (besides @armstrongc93 ) have noticed this issue and know of the cause.
I have filtered the resin, checked the clarity of the bottom of the tank (LT) and checked for any obvious debris or smudges on the optical window. I have also updated to the latest version of preform.
Does anyone have ideas about what might be causing this?
Still having major reliability issues. I have repaired all STLs and scrolled through the layers to make sure there are not unintentional voids in the design - that is not the issue. Designs are essentially tiles with some surface texture. They print just fine on an Elegoo Mars 3, so I don’t think it is an issue with the part design.
Form2s that are still in service now were probably made well over a year ago (closer to two maybe). So any that haven’t been taken apart and cleaned are probably in need of that preventative maintenance task… And it looks like your printer’s optics need cleaning, to me… You can find instructions for doing that in the support section, I think.
Thanks @Randy_Cohen. Support suggested the same thing so we have gone in and cleaned the galvos and main mirror. Trying some new prints today, hopefully that will have done the trick.
I have just started using a Form 2 that has been cold storage since to has been bought in 2016. After some setting up, managed to get it working for white resin from that period as well. (had to clean the electrical contacts as well as slit the discharge rubber cap below the cartridge). 1st couple of small prints worked. After that, large prints (USS Enterprise, etc) has holes. Smaller prints more likely to be complete. Tried shifting model around the platform and checking for debris in tray but no joy. Progressively the print got worst and so I put that down to age of resin. However, I drained the resin completely and it actually looked ok.
Anyway, I change to a different tray, different Grey resin (also from the same era) and printed. 2 of 3 work, 1 partial and I had to fish out debris from the tray.
My question is how can adjust exposure settings in Preform for Form 2 (all latest versions) to account for the old age? I can’t find Form 2 templates to work from, only Form 3 onwards and Fuse 1 onwards. Anyone has Form 2 templates that I can adjust from?
After contacting support and followed through a complete cleaning of galvo mirrors, main mirror and main window, test print works. A reprint of a previously failed print works. Now printing a bigger job to see if printer is really working fine now with old Grey V2 resin (which I have another two bottles). For info.
