Clean and Cure Your RESIN 3D PRINTS the RIGHT WAY!

[@marklafferty5319]

In addition to a uv light inserted into the hollow model, I’ve had great success curing parts in my cure station submerged in water as the water reflects the light through the drain holes.

[@blueckaym]

That's interesting! I was wondering if optic fibers with uv source light won't be convenient to get inside smaller holes (if not too expensive)?

[@Desmo904]

The first print I ever made (Mandalorian about 12" tall) I didn't know about drain holes...until several months later during hot weather when the base platform broke open and liquid resin poured everywhere on my desk! Lesson learned. I mean it POPPED that base wide open. Huge cracks. 😦

[@wkdpaul]

Just started a month ago, I went 1 level above "ghetto" ; got a free broken microwave, removed the transformer and the microwave "canon" and put my UV led power brick in it's place (the transformer is supplied 120v), so I simply punch some time on the microwave, hit start, the plate rotates and the UV LEDs turn on ... And I get a nice "beep" when it's ready 😂

Another thing I do that has really reduced resin in my IPA is airbrushing the outside of model before wash. I was shocked how much came off onto paper towels. I use the same battery electric airbrush you tested on the channel to do it. Also just to be on the safe side for resin inside the model I bought a little uv flashlight and I shine it in the holes. Better safe than sorry. Thanks for the vid.

[@TheCreativeCollector]

Good idea! I might have to try that!

[@monastery4090]

Curious how do you manage the spray of resin? I airbrush off the IPA after rinsing, makes a huge difference

[@InterstellarModeler]

your tips have been very helpful. I had some prints crack on me, particularly when I used water washable resin. Now I'm wondering if the issue was due to the walls being too thick and not using the infill technique that you have demonstrated in your videos (vs it being the actual product). Thanks again for sharing this great info. Will let my subscribers know of your channel when I get a chance.

[@TheCreativeCollector]

Thanks. I've found that thick walls can lead to cracks unless you cure the inside separately. With thin walls you don't have to

[@marblemolly2454]

can you cure inside the printer itself? take off the fep and use the clean tank option on Saturn, for instance.

[@TheCreativeCollector]

I guess technically you could but it would burn out your screen quicker

[@Jayy8Bit]

One thing I have noticed that no one seems to talk about is the actual cure time and how much it can change depending on the resin type. For example, I was using the Elegoo 8k resin and for a 6 inch figure, it would take almost 20 minutes to fully cure. Now I use Sunloo Standard Grey, and it takes about 10 minutes to fully cure. (using the Elegoo Mercury Plus station)

[@TheCreativeCollector]

Yes it varies depending on the print and the resin. Might make for a good future video. 🤔

[@Jayy8Bit]

@@TheCreativeCollector I believe it would! I did a comparison test print on the same Goku model on two Saturn 2's and was amazed by the difference in quality and cure times. Also an FYI in case you ever do a follow up video on supports, Chitubox Pro (not sure about the free version) removed "Support Density". It is now called "Middle Distance" and instead of lowering the number for less of a support jungle, you increase the distance amount.

[@dontknow3949]

Yes!!! I keep seeing everyone saying to cure for 90 seconds to 6 minutes MAXIMUM. That amount of time has no effect on my 2-6 inch prints. Finally I tried for 15-17 minutes and they come out PERFECT. No discoloration or brittleness. Seems perfect to me. But it’s taken me a lot of digging to find anyone saying anything about 10-20 minutes curing, nearly everything I see says over 6 minutes will overdo it and ruin your print.

Absolutely necessary to wash the prints in alcohol unless you're using water washable resin, then you use water. Your best bet is to get a separate tub or container to wash in.

My prints after I wash them on 99% IPA and cure them they feel a bit sticky to the touch. After I clean them on IPA I use an air gun to air spray and dry them well before curing. Could this be caused by the IPA be dirty? I have an 8 litre tank that I've cleaned about 20 prints there.

[@TheCreativeCollector]

Might be a good idea unless you're printing them solid.

[@musashidanmcgrath]

Just wondering why you don't use the cure function on the Anycubic? Have you tried acetone? Much better than IPA or alcohol imo. Large prints with broad detail are fine for IPA, but when you're printing 32mm minis with lots of tiny details the acetone definitely makes the difference. You also get a lot more prints out of it before you have to toss it. IPA/alcohol gets muddy after just a few prints. Acetone is good for around 30 prints.

[@TheCreativeCollector]

I dont use IPA. Instead I use denatured alcohol. It's a clean burning fuel that doesn't leave any residue. A gallon costs $20 and it cleans about 50 large prints for me. Acetone is good but some primers and paints don't like it after it's dried on resin. It can leave a tacky feel. I never have any issues with details plus it's rare I print minis.

[@musashidanmcgrath]

@@TheCreativeCollector Yeah, it was more for your viewers. A lot of people don't know about the acetone. The trick is to swish it in boiling water for about 20 seconds after the 30 sec acetone clean. Prints come out perfect. I work as a miniature and 1:12 scale collectible sculptor so I test print all sizes. I tried everything including the alcohol and found acetone best for my needs. I think it's important that beginners experiment with all the options. It's very daunting for people just starting out in resin printing, especially if they have no background in 3D software.

[@jamestoomey7127]

Thanks for this video Henry, I've been FDM printing for a while but am getting a Saturn S for Christmas and this is exactly the information that I needed. One question: Right at around 5:59 - 6:05 you are going up and down along the hollowed model and it looks like that tab on the back for connecting the cloak pops in on the inside of the model at a place where the infill isn't hitting it. Is that supported okay or will that need more support? Like I said, I am new to resin so maybe I'm missing something but I would think that part would fail until it met up with the larger piece, is that not right?

[@TheCreativeCollector]

So that infill isn't meant as a support really. It's mainly used to maintain the structure of the print. I've never had any issues with prints having pockets. It's rare. And a lot of that is based on how the artist designed it. Fixing that is a whole other thing.

1-drain holes are not just for drainage, it is important to think about where a vacuum/pocket will form between the resin pool and your partially printed object... the holes are not for drainage in this case, they are a way for air to escape, so you can't place holes all willynilly.... if you don't have a way for air to escape in the right places, you'll be deforming the print on every layer. 2- regarding infill to avoid inner support, i thought that was what the 'platform' vs 'all' button is for. 'all' will create internal and external supports. 'platform' is just for what the platform can access.

[@TheCreativeCollector]

You forgot about proper orientation has a huge part in suction too. So yeah....you can place the holes all willy-nilly in this case. Because if you've angled a piece the right way rather than print flat, with drain holes on those angled areas, it doesn't matter where you put them. The lift will compromise any possible deformity. And the all vs platform has no relevance with each other when you're putting or removing inner supports. The grid function serves as a support function and knows not to put inner supports on top of already placed supports. Chitubox has confirmed that.

Gotta say, man, every time you show hollowing and talk about how you don't support the interior, then you preview the layers up and down a few times, you can clearly see that there are islands that are not supported. In one case, you even showed the print after and casually pointed out that the print errored for some reason the peg cavity but that you could fix it. THAT was due to not supporting the inside of the model. Lot's of great info in your vids. I'm totally not a troll. But this makes me crazy every time you show your hollowing.

[@TheCreativeCollector]

Well thanks for the feedback, but the infill isn't really meant to support anything other than the structure. Just to make it more stable if you will. And I'm not sure what islands you're referring to. Maybe its camera angle? But I've never had any resin pockets or islands in my models by doing this. I've printed well over 100 models in the past 2 years and I had only 1 issue, and that's the one in the video. Nine times out of ten when there are fails, it's due to something minor with the printer, resin, or my error, but usually never the hollowing process.

It refers to the inner surface of the print since some artists don't clean the inside and the print can be rigid. This helps when you have to punch a drain hole on an uneven surface.

There is a REASON supports are generated with 0% infill. Your drain holes are all in the wrong places for the wrong reasons. I cannot stress how wrong this video is.
