New system enables faster production, greater optical quality and design flexibility
I am fed up with resin slicers.
Chitubox is about as stable as a drunk on a tightrope, Lychee is bad for engineering models and over-priced if you just want some basic support functions and PrusaSlicer is under-developed. All of these solutions work for different things based on the goals of the user. (For some, Lychee is an excellent value so my distaste is likely not universal.)
What really pissed me off is that support painting shouldn't be a paid feature. You hold the mouse button down and drop a support at specific distance from the last. It doesn't take massive cloud computational clusters or huge storage requirements but yet, money. Fuck. That.
I want a completely FOSS tool that is stable and includes functionality for auto-positioning models and has a full set of knobs and levers for support generation, support painting included.
So, I spent the morning getting a dev environment setup for PrusaSlicer to use as a base for resin-only tools. Over the next month or so, I'll take some time to strip out all the FDM support and get the slicer into a bare-bones state with only the existing resin features. Of course, it'll be on GitHub.
Back to the main subject. I was hoping that y'all had references in regards to anything resin printing: Support placement methods, model rotation optimization, resin strength data, FEP peel force data or anything that could be coded and implemented into a slicer. Hell, even discovering different methods for hollowing an STL would be nice.
Data and strategies for various tools would be nice to have at this point to at least start forming a roadmap for development. (One of the first goals is to integrate UVTools as a snap-in, somehow.)
FDM tools are plentiful because of wide spread adoption. Resin printers still seem niche so printer manufacturers naturally gravitate to writing their own tools for their own hardware in their race to the bottom.
With all of that said, I am actually curious if others would even want to see a project like this kicked off.
Spinner shows while thumbnail is being shown after upload and thumbnail is being generated, but not when actually uploading. (I am attempting to attach gif to this post, but not sure if upload has failed, still going or just not possible.)
I am mobile while I am creating this post, so uploads are laggy anyway.
Search is fine, but there have been several cases where I have wanted to manually enter a community name and instance.
Search can be odd at times and being able to have connect at least attempt to jump to a community would be a nice to have.
Edit: I can now post and view cat pics. Yay!
Searching for "cat" or "cats" yields cat@lemmy.world with Connect, but not from web. "cat" is an invalid community.
cats@lemmy.world should be correct community and listed in search results.
I am simply on a quest to find an effective non-distillation method for purifying isopropyl alcohol used for rinsing resin 3D prints.
I have seen some elaborate systems for curing and then filtering resin that is suspended in the isopropyl by running it through standard carbon water filters. That just seems a bit over-complex and does a poor job of removing dyes. In some cases, the filters are not fine enough and the isopropyl will eventually get "sticky".
It seems to me that a finer filtration system would work much better. Carbon and celite should catch most of the monomers and oligomers, but I am not sure about the photoinitiators and other additives.
Distillation is obviously the best method for purity, but there may be a worse cleanup and a higher fire hazard risk.
Are there better materials that I could use for filtering besides celite and carbon? IPA is tiny compared to the rest of the molecules I am dealing with so filtration seems viable.
(I should note that I would bulk develop the used IPA in clear plastic containers in the sun for a day or two first.)
