i print soap dispensers, 1.2mm thick single wall vase mode, .6 nozzle. and 5 base layers. ive been using 1 of my prints for a good 2 months now for hand soap in the bathroom and its still watertight. ive used over 15 different types of colors/filaments and i dont have any leak at all. its 70g in filament and a few hours of printing for each one. EDIT: forgot to mention, the default infill overlap is 25%, i set it to 50% in order to make the bottom layers overlap the wall slightly more, completely sealing the bottom so that there is no leak in the transition of complicated geometry

Another thing to take into consideration is the material you print with. PLA is porous and it was recommended to me not to use it for watertight objects. PETG is very similar to PET, the same material used in plastic water bottles. Not that you couldn't use PLA without success, but some materials will work better than others.

I printed a scaled down vase in purple PLA and it still holds water 3 years on, but the VRM blocks I printed for a chinese mainboard for shits and giggles a year ago were done in Creality branded PETG, but had to go real slow with the fan off.

@@DevilbyMoonlight Why didn't you want the fan on? Was it necessary for the extra heat-melt?

It's hard to make assumptions about whether the complexity of the object influences water tightness when you yourself say that pressure is greater in your larger vessels. You need a single wall thickness "cup" with the same volume as your larger, more complex walled designs. THEN if the large cup performs better wrt. water tightness, you can make a claim about surface complexity and layer adhesion affecting water fastness.

@oceanic8424

It would be much more accurate to make the larger cup taller in height, not just simply larger in volume only; since the fluid pressure is greatest at the bottom of the container. As a real world example, those very large welded steel plate cylindrical oil storage tanks commonly found at oil refineries use much thicker steel plates at the bottom than in the higher up plates. The wall thickness diminishes the higher up they are in the tank (reservoir).

Unfortunately you didn't mention your nozzle size, what material settings or band and most importantly your slicer settings.

I've been 3d printing surfboard handles that have to be water tight. Using 100% infill and ASA, what's nice about ASA is i can use acetone to smooth the surface finish so the layer lines all merge together as an extra but of insurance.

the key ive found to watertight prints is increased extrusion multiplier. 4-5 perimeters with anywhere from 110% to 125% extrusion rate

for me i dont have problems with the walls, i have problems with the bottom. Just need to up the flow rate in my experience. Another way to make sure the walls are good is to make it print the outer walls first, then the inner wall with a higher flow rate so it fills any gaps between the two outers.

I have been able to make some prints water tight by increasing the Extrusion Multiplier in Prusa Slicer to 1.5 (150%). It even works on some simple vase mode prints

Thanks this was very helpful ...Can you please do fastening load test on filaments? or whats the best filament for say metal fastener strength inch pounds etc ..?

What microcenter filaments did you use gor these two containers?

i 3d printed a little watering can out of PLA+ and left water in it for over a month with no sign of leakage. I was impressed, this was before i knew it wasn't common for 3d prints to be water tight.

If the prices for a purchase and a print are very similar, you should add the electricity costs. That's not to be neglected!

Holy poop, fusion finally made a dark mode?! That’s awesome!

Seems like the cheapest and easiest fix to this would be epoxy and baby powder brushed layer.

I've been using a 3d printed waterpot to rinse my brushes from mini painting for years now. Never really had a problem, even with ridges and other corners it works very well

I want to say thanks for making these videos. To say that they are helpful is an understatement. As a new, rookie 3d printer user,I have no idea about how to make my own designs. BUT I do want to learn. I have subscribed to your channel and will be taking ur masterclass to learn how to use fusion 360. But I have a question regarding 3d printed cups. Are they safe or have any of the filaments been tested to be safe to drink ANY liquids from whether they be hot or cold if u were to use the right filament for either hot or cold liquids? I ask because one of the goals after taking your masterclass is to 3D print my gf a coffee cup if its safe to do so.

If you use PETG it is food-safe, and that is the same material water bottles are made of

Is it possible the first one just leaked at the seam lines on the outside?

When you gave an estimate for the printed cost you never mentioned the price per kg. May I ask how much your filament cost per kilogram?

Lead in nozzle problem, any good solution?

I think a unique selling point for 3d printed products is that you can't buy them at a store, you can only print them. Their cost is secondary.

Nope. Heat is used to soften the plastic for printing. Hot water will soften it just like the 3d printer did. Keep your prints out of the dishwasher/engine compartment.

The golden container hold water well 💦 3:52

Physics says no. You can buy chemicals that try to make it waterproof but still the water is absorbed into the print itself. If you can find a strong enough microscope you can watch the water being absorbed. Just measure the water, leave it for two days and measure the water again. Hint, there are holes in the material you have just printed. Any voids will be full of water, say like a model of a submarine and you can shake it and hear the water inside, even if you print it solid it still absorbs water.
