[@ryantakahashi9130]

There was a recent post in the r/SFFPC subreddit where a user 3D printed molds instead. Then used regular hardline tubing and used heat to fit them to the mold. Was able to achieve something super complex but without having to go resin and print the full tubes. It would work great for an SI when they have fixed configurations, they could just premake all the tube runs with ease.

[@boxhead6177]

Custom Scientific Glass Blowing has a similar process where they use regular tubing and stock glass to form custom pieces for laboratory and manufacturing use which has to be of a high standard for professional use to withstand heat and pressure tolerances fit for purpose. Or if you think of it as a prototyping route, make a model test fit... and then go completely over the top and follow an artistic route glass blower/sculpter to make the final product. The looks you could pull off like go full glass crazy straw, mad-scientist labratory glass kit, abstract art like a glass knot or klein bottle, or waterflow sculptures.

[@sykesmcenzie]

If you don't want to resin print you can fdm print casings to hold softline tubing, you just thread the tubing through the printed casing and you have your shaped tubing

Every week? Eh, if the capacity is like common loops, several times a day to once every hour or so running an i9 with load on it. You'd have to demineralize the loop once or twice a day or your pump won't make a full day without seizing. Realistically you'd have to automate refill based on some level point or you'll cook stuff or have auto shutdown due to thermal alarm constantly. Think of it this way, would you want a 100w+ air humidifier?

I didn't realize there was a scanning spray that cleaned up with sublimation. I was only aware of ones that required manual cleaning. Going to have to give it a try.

[@Sirotaca]

I use it all the time in my job. It can take quite a while to fully sublimate, but even if you end up having to clean some of it off manually, it's still a lot less messy than dealing with the non-sublimating stuff.

You could also 3D print the reservoir, distribution block, and fittings with O-ring grooves. Plus you could vary the width of tubes, adapt between sizes without fittings, and make structural or decorative components that are part of the loop. Even FDM prints can be water tight, though it depends on material and print settings.

[@Waldohasaskit210]

You can add a bit of adjustability into the tube as well by adding extra bends that allow some 'squishiness' in certain directions, depending on the rigidity of the plastic used.

[@DarthPoyner]

The resin is usually very rigid. And putting more bends in it than necessary could lower your efficient fluid movement. You can't just heat bend it like the plastic or the glass.

You absolutely can use FDM printing to produce watertight objects, I have done it myself using PETG and even in vase mode (where the wall is just a single continuous extrusion). You just need to have well tuned settings. PLA isn't good for watertight objects but most other materials are absolutely fine. Yes prints have layers but if your settings are right then the layers should be fused enough that there isn't any gap.

[@tronosgamingwizard]

[@hed420]

Oh it will. I thought about doing this almost 6 years ago. Turns out that resin prints dissolve in water. Hope that the resin they used resolves this issue.

[@Konigstiger]

@@hed420 There are plenty of resins that aren't water soluble. In fact, can you guess what kind of technique dentists use nowadays? Surprise! Resin 3D printing.

[@MaethorDerien]

Well resin has been known to be water tight for years. Most of the resins for hobby use don't stand up well in water. That said there are plenty of ones that are water safe. Some of the new ones that you can thermal cure on top of the UV cure so you don't end up with the uncured internal resin issues although it is absurdly expensive and I don't think I have seen clear.

[@RylTheValstrax]

Resin toxicity varies dramatically depending on the formulation - and there are low toxicity formulations that are dramatically safer to use, but be aware that to achieve low toxicity tradeoffs in cost, mechanical (ex, tensile strength, glass transition temp), printable (viscosity, curing wavelengths, curing time, etc), optical (coloration, UV stabilization, opacity), or chemical (water sensitivity, ozone sensitivity, etc) must be made, so do your research on what you need to make the print actually function in its intended role and its compatibility with printers/curing lights/etc. I personally work with a very low toxicity PMMA/acrylic formulation for most of what I do personally, but while its got pretty decent mechanical and cost properties, it does make notable tradeoffs in chemical (high water sensitivity causing hydrolysis of the plastic before being fully cured), optical (low clarity on "transparent"/translucent prints), and printable (high viscosity) properties

4:04 means your settings are not correct, although it's less relevant because you can coat the stuff in epoxy. I printed a part in petg for a hydrolic tank and it is indeed water tight. There is a alternative where you fill the part with sand and put it in a box of packed sand then heat it enough to somewhat melt which will also seal the print.

[@the_undead]

Maybe on a high-end printer I would agree with you, but on a lot of the extremely low quality low-cost consumer models, I would not expect those prints to be water tight. And yes, there are solutions for that problem but coding an entire tube in epoxy at that point, why don't you just use traditional hardline methods because it's impressive enough for way less manual labor
