- With Tangled Filament officially launching in the VERY near future, we are fully on The Road to $10 Filament and our goal is to bring you along the entire way! Our first pit stop on this exciting journey, is designing a 3D printed water dispersion attachment to address turbulence challenges in our filament cooling tanks.
Turbulent water flow in the cooling tanks can cause inconsistencies in filament diameter, which is detrimental to our vision of producing HIGH-QUALITY $10 filament. To fix this issue, we have designed and printed a hose attachment to relieve some of this turbulence. This attachment is designed for optimal print orientation and features unique geometries only possible with Mass Production 3D Printing. We go through the principles of 3D printing mechanical design and how it can revolutionize even age-old machinery. So join us, as we showcase the advantages of design for 3D printing by achieving in-house solutions that were never possible before.

About Slant 3D
🏭 High-Volume 3D Printing: Scalability Meets Flexibility
Slant 3D's Large-Scale 3D Print Farms utilize 1000's of FDM 3D printers working 24/7 to offer limitless scalability and unparalleled flexibility. Whether it's 100 or 100,000 parts, our system can handle it reliably, while still allowing for real-time design updates, ensuring products evolve with the times. This adaptability is key in today's fast-paced world.
🌿 Sustainable Manufacturing: Eco-Friendly Efficiency
Embrace a system that drastically reduces carbon emissions by eliminating carbon-intensive steps in the supply chain, such as global shipping and warehousing. Our approach minimizes this footprint, offering a more sustainable manufacturing option.
⚙️ Digital Warehouses: Parts On-Demand
Think of print farms as a "Digital Warehouse", meaning we can store your parts digitally on a server rather than physically on a shelf. parts are available on-demand, reducing the need for extensive physical inventory.

Great engineering design discussion.
With fish tanks, the pump mechanism is often located in a isolated chamber in the tank, or in a separate tank, to reduce turbulence, and then over-flows into the main tank as a laminar steam. A horizontal divider in tank between the water inlet and filament (if positioned between the two at different levels) could help ensure a laminar water stream, further reducing turbulence acting on the filament.
Great practical application example. These engineering vids you guys do are great! They have been helping me tremendously. Keep it up!
I can't quite grasp how making certain geometries angled turns islands into loops in the slicer.
Pause the video when he shows them, then use the right and left arrow keys to go frame-by-frame though it and you can see what he's describing.
@@glabifrons I'm not getting it... Looked frame by frame and I don't see what's special at all. Maybe someone can explain it...
I think it's something like this:
Normally, a side view of a slot in the print looks like this:
pppp
pppp
_____
pppp
pppp
The _ are the hole
When the hole is slanted, this happens:
pppp
__pp
p__p
pp__
pppp
There is still a hole through the part, but every layer has something to print. Therefore, the printer doesn't have to stop jumping from one side of the hole to the other, it can just keep printing.
theres a video about a smoke detector in the same channel showing various examples
IT's probably not a big deal for your application, but i doubt that hose connection is not leaking. furthermore since you have it tapered the forces (although also probably not a big deal due to low pressure) will be pushing the hose off the connector. A classic hose barb has smooth circular surfaces for the hose to seal and then a barb to keep the hose from being pushed off by the pressure (secured by a clamp that is not very elastic) The clamp also pre-loads the gasket surface (hose to smooth surface of barb) to seal the connection. Such things can also be overcome by an appropriately elastic hose over an appropriately sized barb within a pressure rating. I'm a mechanic professionally and your hose connection has got me a bit rankled, even though your very sub par design is probably just fine for your application. Although, if you're using a pvc hose the connection probably will become loose enough to push off eventually.
I always learn something new watching your videos.
I clicked on the video expecting a quick update on your filament manufacturing process and was very pleasantly surprised by an excellent tutorial on engineering design for additive manufacturing, and a great example of how 3D printing makes parts that couldn't be made any other way. Sure, you could have machined a water diffuser but it would have been much more expensive and wouldn't have worked as well.
Even when a part can be manufactured via different methods, with machining, there is a large cost to complexity because it greatly increases the machine time and operator labor for each part. With injection molding, complexity adds to the design cost and the mold cost ($$$), but after that it's free. With additive manufacturing, complexity adds to the design cost only, and I'm an engineer who is working for peanuts in my sole proprietorship. 🙂
One thing that would be interesting: over at another US manufacturer they sell "transition rolls" for a very reasonable price. These are the gross rolls of filament they don't toss, but rather package up when they're changing colors and they sell them for a discounted price. This is another simple way you could help reduce waste. Especially if users don't care about color for functional parts.
In the works. Spooling transition filament onto other manufactures leftover spools from our print farms.
Awesome!
I actually did something with the exact same principles a couple weeks ago for some gardening equipment. I also used diagonal slots for a grill -- something I learned about in another video from this channel.
I couldn't quite figure out how to get the grooves in the thing without it needing some nasty supports when printed sideways, but I think the hexagonal shape might help with that.
Thanks for the inspiration!
tips if you would want to design the perfect bath for cooling. probably overkill, but i like the brain exercise.
1 make the area where the filament first gets into the water as stable as possible, as long as the water is below boiling point, you can even use a wall to compartmentalize the area. leaving a gap at the bottom and surface to have some flow.
2 put the water spout at the end of the filament line where the filament is probably cool enough to not warp anymore.
3 more holes, lower flow rate. over a larger area creates less turbulence
4 use a heat exchanger to cool the water without any turbulence.
also if you make a video about something, make good before and after shots so we can see it in action.
Very intriguing!
yessss excited for the two kilo spools
Could some type of laminar flow system be used? The disturbace could probably be directed in a particular way or none at all.
Is this the process used by most filament manufacturers? If so, then could this be the reason I’ve been receiving water-logged spools of filament from even the major manufacturers?
Interesting!
My first thought would've been an adapter for an irrigation line, spreading water across a distance is right in that stuff's wheel house.
Re: impossible geometry, is the closest you'd come to this with other processes, two injection-molded parts ultrasonically welded together?
3D printing with metals is also taking off, especially in firearms and automotive engineering rn. You are now getting suppressors for rifles 3D printed to take full advantage of the geometries it allows, as well as unique designs for radiators, engine blocks, etc. that casting just can't accomplish.
- Ocagonal spout for printability
- Round inner diameter
Smart
Ok but hear me out:
A sprinkler hose (hose with a bunch of holes in it) along the bottom left side of the basin?
Maybe even coil it if the flow rate is not enough
That would work. Although it's not a big deal for them to 3D print something, being they are already a 3D printing business and it's only a few cents of filament to print something like that.
@@logicalfundy I'm sure the time designing it cost more than a soaker hose.
@@logicalfundy But the hose solution would also disturb the water far less.
