    I have an Anycubic 3D printer I bought a couple of years ago and haven't yet had the chance to use. While I'm experienced with 3D printing, particularly with the FDM process, I don't yet know much about resin printers.
    I want to print some supports for a platforn canopy somewhat like those shown in the photo of Saginaw's Potter Street station below.

    My question is: What is the minimum wire size and wall thickness for parts made with this material/process?

    There's so much that depends on that it's hard to answer. I have wires that I've printed at around .34mm (about 2 real world inches) but that's pushing the limits. Your LCD panel has a resolution of .047mm so the limitation isn't with the screen, but more of what forces can your print withstand while being ripped off the FEP on each layer without getting pulled apart. And that is dependent on geometry, resin, exposure, and orientation of your object. For rolling stock shells I use a wall thickness of .8mm - 1.1mm.

    To get your going, I'd recommend starting with a print that isn't as delicate as those supports just to get a feel for your Photon and the process. Then once you've got it leveled and exposure times dialed in, start experimenting with finer detailed items. Feel free to ask more questions and share results.

    Good luck! -Mike

    Thanks much, Mike. For us old dudes who still live in the inch system (yeah, I'll probably keep converting to inches at least until I die), .34 MM is about .0134", just over an HO scale inch. I will keep in mind that is pushing the envelope (pun intended), but I would regard it as excellent compared to other processes. I was thinking of using a somewhat less lacy design with a wire of about .020" (roughly .5 MM). I do have another somewhat more robust part that I will be starting with first. Will post results when I get them
