Are 3D prints water tight?

[@xXP1ZZAxD3MONXx]

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

[@xXP1ZZAxD3MONXx]

@@gotmilkbutt yeah it's holding soap, and other soap containers may not have layer lines for bacteria to hide in, but do you ever wash the inside of your soap bottles? Cuz I sure don't

[@hunszaszist]

​@@xXP1ZZAxD3MONXxIf a bacterium can survive in a soap bottle it deserves the comfort of my mucus membranes as a consolation for that torture. Besides, it's not like washing my hands would've done anything to prevent it from entering my body.

[@xXP1ZZAxD3MONXx]

@@hunszaszist uhhhh yeah sure we can go with that

[@3DPrinterAcademy]

very cool!

[@denisflorian2431]

@@xXP1ZZAxD3MONXx soap kills bacteria. Why are people misinformed about this lol. If it didn't kill bacteria we wouldn't have needed it.

[@lajoyalobos2009]

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.

[@Retro-Future-Land]

What about ABS plastic?

[@DevilbyMoonlight]

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.

[@Retro-Future-Land]

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

[@johnheartmarcos967]

Can we use uv resin and some sanding to make it water tight? we use pla+ in our 3d printed water filter as an experiment, please give some advice I'm a beginner on 3d printing

[@FrostyDeagz]

Yes u can ​@johnheartmarcos967

[@KieranShort]

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).

[@KieranShort]

@@oceanic8424 good point 👍 PSI

[@noktrnl123]

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

[@AndrewWorkshop]

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.

[@xIsouLcruSHca]

How do you get ASA to stick to the bed reliably? I tried with vision miner adhesive but still comes loose very easy and warps like hell

[@AndrewWorkshop]

@@xIsouLcruSHca Glue stick or a slurry of ASA (acetone with some scrap ASA dissolved in it).

[@AdamWebb1982]

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.

[@dougwinning449]

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

[@leibi]

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

[@3DPrinterAcademy]

true!

[@2QRh6g1I]

We should amortize the cost of Amazon Prime membership too! Or factor in the cost of shipping.

[@pavelperina7629]

Bambulab A1 consumes like 80-100W during print and 180W during initial bed heating. Even in Europe it's quite negligible - tens of cents for 10 hours.

[@htpkey]

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.

[@3DPrinterAcademy]

100% (and its fun haha)

[@gutrali]

Why can't you buy them in a store? Maybe Walmart doesn't but there are plenty of other places that sell 3D print and 3D print commissioning service. Etsy is probably the biggest one

[@htpkey]

@@gutrali You are correct, there are people who sell 3D printed stuff on Etsy. I was thinking about mass produced products when I said "buy at the store".

[@AndrewAHayes]

I made a few self watering plant pots and placed some plants in them and gave them as gifts, I was concerned about the water reservoir leaking and so I ordered some very cheap photo resin and a small UV torch and coated the inside of the water reservoir with resin, they were water tight although I only had a few drops of water appear on one of three plant pots before the resin.

[@danielhastings3167]

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

[@Tizzandor]

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

[@arnotschmitt8986]

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

[@hobonickel840]

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 ..?

[@jonatanboy]

[@FreedomFishing]

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

[@debrasam5525]

What microcenter filaments did you use gor these two containers?

[@dwang085]

[@stefanhauser2804]

[@posxd3865]

Is it possible to make airtight prints as well? I need a specific pneumatic valve, I'm I able to just print hem?

[@3sotErik]

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?

[@IbnBahtuta]

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.

[@kiiiddd]

Need a bigger nozzle with thicker line width

[@gilsoutherland3562]

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.

[@mkhjensen]

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

[@anticorporatists9959]

What about very hot water

[@bradleyj.fortner2203]

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.

[@aaronalquiza9680]

"very hot water" can also deform some of the PET/plastic products sold in stores no?

[@Curtis_lee]

hey so i just got a new ender 3 and im new to 3d printing and my printer is printing more like mesh then a solid piece. do you know how i can fix this?

[@3DPrinterAcademy]

Could be a lot of things: 1. Make sure the temperature is set correctly for the material you are printing. 2. The nozzle could be clogged: 3dprinteracademy.com/blogs/basics/clogged-nozzle 3. Could be heat creep: 3dprinteracademy.com/blogs/3d-printing-basics/heat-creep-jammed-hotend
