@CPSdrone have you considered using "Corrosion X HD in all the stepper motors and connectors. Also, pour the silicone in smaller/thinner layers and it will dry better. Also maybe consider your layer smash/ thickness. With the print happening under water maybe you want the tip of the nozzle to "dig in" to the previous layer to get better layer adhesions. Maybe. At this point everything is trial and error.

The only thing that would be the problem is as the plate goes down making sure the water stays level. I'm sure that could be figured out though... gravity, siphoning, something.

@dapz 7 ай бұрын

I wonder if instead of submerging the entire printer completely you could have a small secondary nozzle that shoots a stream of water at the recently cooled part. You wouldn’t have to deal with as much insulation or waterproofing, nor the heatbed losing a lot of heat to the water. You could have the jet of water be cooled by an ice bath or water chiller, allowing potentially more water cooling ability and stiffness for overhangs, and then switch to hot/no water for the parts that need better layer adhesion. Kinda like the equivalent of flood cooling on cnc mills but for printers

This generally has an interesting application for semi-cristalline materials. Given their crystallisation rate is basically -x² with both points being y=0 (y being the cristallisation rate, x the temp) the tg and the melting point. Given cooling down to tg isnt possible for some filaments (POM having one of -80°C) you could keep the liquid temp just below the melting point of the filament. For this application a non-oil based liquid with a boiling point of over 200°C would be needed. But if you can get that liquid, the rest would be pretty easy given the Hotend basically needs no insulation Basically by keeping the material just below its melting point and easing gravity with a liquid you could keep the crystallisation rate at almost 0 making warping bc of crystallisation insignificant

@conorstewart2214 7 ай бұрын

That would maybe reduce warping but it would also make it pretty much impossible to print, if the whole print volume is just under the melting point the plastic won’t cool fast enough and will deform, on top of that most 3D printing materials go soft well before their printing temperature so would deform because of that too. With heated chambers and beds you want to have the temperature below the heat deflection temperature or glass transition temperature to reduce warping but also to stop the print melting or deforming.

Your fluid would have to be the same density as the filament so the parts dont sink or float and be thick enough to not be pushed around and deform your part. Anyway the same issues exist, having the part heated to much higher than its glass transistion temperature would make it very easy to deform, with a fluid even the currents caused by the hot end moving might cause it to deform and gravity definitely still will.

What if you'd attempt to build a printer that would use a belt system to move the gantry underwater but keep the steppers in the air. (Something like an inverted Ultimaker S3, where you don't see any stepper motors at all) You'd still have problems with isolating the nozzle, one way that maybe would do this, if you'd have an unlimited budget would be aerogel, sadly that's not a realistic option currently. I didn't see if you have pulled a vacuum on your red nozzle bath, if you would suck all the air out before letting it cure you won't have gas bubbles that will form later on. One way to stop the plastic from collecting moisture would be to attempt to enclose the whole filament system so that no water gets inside. But then you could encounter problems with the water trying to get into the nozzle from the bottom which could create weird things.

I see massive advantages regarding cooling when printing under water. for example that water has a similar specific density to PETG, meaning that you need almost no support to support. PLA has a higher density, but not bad. you will need some sort holes as an opening to the infill to drain the water. and since you will probably not be able to change the nozzle, I'd suggest the diamond nozzle, it is practically not degenerating when using it, it might outlast your printer.

you could use 2 component silicone for the nozzle bath. It doesn`t need air to cure and should cure all the way through

there are also high temp ones which should be able to handle the nozzle temparature

I work in HVAC and have a passion for engineering that spawned out of that career. I started programming as I could use micro controllers to replace hard to find or ancient logic boards in systems. I decided to get into 3d printing because of the need for industrial parts. I heard about the problems of moisture and have been watching video after video and just came to this thought... These people are looking for quality. If you print under water than why am I worried about humidity lol. I'm making industrial parts that will never be seen. I'm very lucky in that way actually. Long as I can bash it on the ground without it breaking I am good to go. Also gives me the ability to print on low end printers.

You need to provide two things. cooling speed and you can use instead of water oil with a density similar to that of PET-G, i.e. approx. 1.3g/cm3, then the print will not sink to the bottom. you will get a perfect bridge without rust :)

Pretty much exactly what I was thinking.

You might want to do what we used to do to protect locking hub assemblies from moisture intrusion in our off-road vehicles: Add a fitting and pump air into the stepper. The air exiting through the small gaps tends to keep water from coming in, and will also push water out.

Now I'm wondering what the overhangs would be like with a more viscous liquid than water.

Pretty monumental guys. Awesome job.

If you used a core xy it would have been alot easier since everything could have been outside of the liquid and only the print bed gets lowered in the fluid. or just add better aircooling
