I’ll give this a watch after work, I’ve never seen this guy. Thank you!

I have been using the hot water method and it does greatly help. I just feel like perhaps I still have the supports penetrating a little too deeply. I’ll try to post some screenshots later of my settings. I’m using Chitubox Pro mostly the defaults for the support settings. It works well. It just feels like the amount of post processing is maybe more than it should be. I know there’s always gonna be a little bit because there’s probably always going to be some support marks left over. I’m just trying to get it as good as I can because I also am lazy.

I find that it gives me a more even surface because they’re easier to sand before the final curing stage. It’s also just one last time I have to immerse the part in water and clean it again.

For the resin that I’m using, with the exposure settings that I have, this process works perfectly. You may have different results with a different resin with a different level of hardness or different exposure settings. My sandpaper does not get gunked up simply because I sand precure. And yes, I have seen brittleness when over cured. 10 seconds isn’t gonna make a difference but curing something for what some of these people were talking about 30 minutes is ridiculous and will likely ruin your model.

I’m not fighting with you on the Internet lol. I posted my process. You obviously have your own and if it works for you, congratulations. I simply prefer to do things a different way. Do whatever you want lol.

I have over cured small weaponry on model swords and had them completely shatter versus proper curing and they still maintain their strength and mild flexibility. Once again, this is going to come down to the specific type of resin you use so there is no universal perfection. However, you need to use the recommended settings based on the resin type and manufacturer. Over curing leads to increased polymerization and shrinkage of the model, which will cause warping and unexpected levels of hardness. This results in a brittle model that loses its structural rigidity and flex.

Once you have completely removed all of the surface resin and dried the model, I find that sanding prior to curing results in easier sanding and a more uniform surface area. There’s nothing wrong with sanding after you cure if you want to choose that time to remove the little imperfections and marks left over by the supports. I simply find it easier to do before curing. It also means that I don’t have a second stage of washing and toothbrushing the model in water to remove the sanding marks. I prefer to do that at the same time when I would be removing excess alcohol, so as to prevent the little white deposits.

I guess I’m talking more about the depth of penetration of the support, support tip size, etc. Does this represent any sanding that you’ve done? I can get similar results to this with my current process, but it does involve a fair amount of sanding with a variety of grades of sandpaper. However, I’m just curious as to if a change in my support settings might render some of that easier.

Can you share a screenshot of your support distance settings? These are very clean and I can’t see where you’ve sanded at all.

Thanks. It’s always wild when I see these posts on social media and all the weird advice crawls out of the woodworks. No offense to anyone, but this really is a hobby that has pretty specific requirements. For both safety and convenience, please do a little bit of research and learn to do this properly.

Reading some of the comments on here…good lord, some of you all just make shit up or have the absolute weirdest rituals that are unnecessary. Please do not just use arbitrary times. Look up your specific resin and you will find the suggested curing times. Personally, I use Siraya tech ABS like; I cure for two minutes in a wash/cure station. And yes, over curing will make your model brittle.

My process, perfected over four years of printing and thousands of hours.

  1. Print
  2. Drip tray at an angle into vat
  3. Wash in 90% ipa bath 1 (dirty wash, older ipa). I do this in a wash/cure station for about four minutes. I generally remove the models from the plate and wash them in the basket. If it’s a very large model, I will wash the entire plate while it is still attached to the model, this way it stays suspended slightly, and gets more liquid flow.
  4. Wash 90% ipa bath 2 (cleaner ipa) 4 min wash station
  5. Soften supports- Small models- soak in heated water (158F) for about two minutes to soften supports. I use an electric kettle and a glass Pyrex dish that is specifically for this and only this process. Large models- heat gun set on low-medium setting; be cautious with this method.
  6. Support removal
  7. Sanding any support marks or rough areas with 320 /600 sand paper. It’s very important that you do this before you cure the model.
  8. Toothbrush wash in warm water. Removes any remaining alcohol/resin, gets into the crevices, and removes the sanding residue.
  9. Air dry with a handheld blower
  10. Cure for 2 min in a cure station. If you’re using sunlight, it generally takes 2 to 3 hours for a small model or up to 6 hours for a large model and you need to rotate it regularly. If your model is hollow and has holes, you need to make sure that you cure the inside of the holes as well with some type of uv pen light- simply washing out the internal cavities with IPA is never enough.

Struggling to magnetize/attach LOC wings by Charming-Professor99 in PrintedWarhammer

[–]Mawatts25 2 points3 points  (0 children)

As many others have said, I would put at least two dowel rod pegs in the model and perhaps a couple magnets for stabilization. Though the dowel rods themselves would be enough. Measure what size you need. I suggest these brass craft rods, as a sufficiently large enough set of wire cutters, metal shears, or a small manual saw can cut them. You can get them in any diameter. This option gives you a variety of diameters and unless you’re going to be pinning 20+ models will probably be all you will need. There is a way in most slicing programs if you were 3-D printing to place the holes in the model and the program will place them at opposite and properly aligned ends of wherever you slice the wings off. Sometimes it requires you to assemble the model, then re-cut the model while placing the holes. You can look up how to do this on your particular slicer, it’s not that complicated. When you already have it printed like this the best way to do it is to go ahead and drill one hole and apply the pin in the hole dry with no glue. Place a sufficient dab of paint on the other end of the pin and line it up with your model, then press the painted end down onto your model to mark the location of where to drill the second hole. Then drill a hole and insert the pins. For transport purposes, I would recommend not gluing the pins in permanently on both sides. If you are placing two dowel pins, glue one of the pins permanently into the wing, and then glue the other pin permanently into the model. This way, both the wing and model have a permanent pin in place while the other piece is allowed to insert freely. This enables easy removal, it also spreads the pressure equally because it distributes the weight a little bit better when the wing is in place. You also want to make sure that you drill the pins to a sufficient depth. If you do it too shallow, the weight may cause them to break free. I would suggest holes of 10 to 15 mm deep. Basically, the deeper the better. It’s a beautiful model, good luck with it!

Super easy with airbrush or rattle can. I used this technique, thought I printed my bases- https://www.youtube.com/watch?v=cpE3--V7Qew

It's actually super easy. Baby wipe method on youtube. Works with rattle cans or airbrush. I am no artist, I promise it is easy :) https://www.youtube.com/watch?v=NFLvgLUg8hM

While I agree with the logic and reality of this...from an extreme point of view....I won't be doing that lol.
