There is MORE to this HOOK than you think! (Multi-Material 3D Printing)

- เผยแพร่เมื่อ 2 มิ.ย. 2024
- These simple coat hanger hooks nicely show what multi-material 3D printing can achieve, by overmolding a PLA part with foaming TPU. This generates a nice and sturdy part with an internal soft padding to not scratch the paint off my railing. Let me show you how I did this and what challenges I had to tackle!

Polymaker’s pa6-gf dropped by 40USD on Amazon for 2kg, could be a good time to get it for a future video.
Nice Wanderschuhe!
is your cad softwere free
After watching your video, one head that I think should work *VERY* well is a spindle that is specifically for travelling along the outside walls, trimming them to final size. That wouldn't take much power, yet would remove surface blemishes/over-extrusion/etc. You could even *deliberately* over-extrude a little just to have a smoother final finish. Does that make sense or am I missing something?
@CNC Kitchen Recently i wondered if there is a list of 3d printing materials for multimaterial 3d printing. Like which plastics stick to which, which ones should not be used in combination or something like that.
Multi-material with variable density TPU? What a flex!
Great joke, do you write down your MaTeRiAl?
Sounds like printed shoe (soles) might be a good thing.
Weird, but ok
@@Jacksparrow4986 plenty of them in the market -> Adidas 4D
@@thomasfeix7979 buying is boring :)
Actually PrusaSlicer offers the option to extend the skirt up to the last layer to prevent oozing for multi-extruder (advanced mode, under "multiple extruders --> Ooze prevention --> Enable). By setting the correct number of loops, you do not need a purge tower because the nozzle will purge on the skirt. I have used this with E3D Chimera hotend and it works quite well!
Overengineering practical parts is definitely a "weakness" I can relate to, because it's fun! Looking forward to a multi-nozzle printer for the same reason: being able to mix materials.
Its a great way to master CAD though.
excellent design of the hook Stefan and very well explained process 😊
Thank you! Cheers!
Wow, the quality of this video is off the charts!
Thanks. That's always great to hear.
When you know in the first few seconds that it is going to be an awesome video
This seems like a simple coat hanger, buts it’s an auto sear lol
No way.. how??
@@raam1666 nah, that’s a meme, there was a guy printing auto sears and selling them like coat hangers lol
I like how this is the only comment here that acknowledges this haha
Yankee Boogle time.
I was looking for your comment LMAO
I absolutely loved this video style where you also show some tips in fusion. This is excellent for learning new tricks and I will definitely apply them
I would have added two ridges that would snap to the underside of the rail.
Exactly what I thought! 👍
As a German you gotta overengineer stuff, you know?
Was ich an deinen Videos liebe:
Dedaktisch und qualitativ Spitze!
Ich lerne immer was dazu und sehe neue Dinge!
Die Multi-Tool Maschine ist sehr cool. Gerne mehr zu diesem Thema!
Statt over-engineering sag ich gerne "Optimierung", diesen content lieb ich besonders.
Dein neuer Style, dein Auftritt am Ende des Videos wirkte sehr frisch und glücklich das freut mich!
One of the most interesting 3d printing videos I've seen so far. Its great to see the e3d toolchanger in action. Wonderful job!
Actually this just demonstrates the beauty of material science. Composite material from steel to fibreglass have always show superior properties than natural material and this also elegantly demonstrates that.
I've used this technique as well in a few of my projects very clever, the mechanical interlocking of dissimilar materials!
Love our e3d toolchanger! Thx for the video.
It looks like it's foam tape on the part from afar, but when you come closer, it's much more.
For an ooze shield in PrusaSlicer you can always increase the number of skirt layers. So that the skirts works as ooze shield
Great project Stefan, I especially like the tips on blending the 2 materials to help adhesion.
Very excellent use of multi-material!
Way too over-engineered for just a coat hanger, I wouldn't expect anything less 😂 I love it 👌👌
Yeah... Shrink tubing over hook is same product, only made five times faster.
Please explain that to my wife...
German engineered!
A tool changer is really useful for changing tools
Awesome! I am in the middle of building a Jubilee tool changer (based of E3D tool changer). I planned on doing the same thing (multi material prints), but with fiberglass filled nylon and TPU.
love that OmniaDrop! and, as always, wicked cool video!
This video really hypes me up for my IDEX printer! The possibilities are endless!
Finally someone who does more than just multicolor prints or soluble supports! My most useful multi material print - yet - was a cable entry for a 2U rack frame with PETG front plate and flexible TPU fingers towards the cables.
Love the editing style!
Thank you!!
Guten tag Stefan! I love your channel, very well worded and informative. Thank you for the knowledge👌
I like using a toolchanger to have different nozzle sizes, even for the same material. I have a volcano on one tool and a regular e3d on the other. Still planning to use flexibles some day like you've done, so this video was very cool to see.
I cant wait for bambu lab to release a printer like this. The X1C just blows my mind every time I use it. Even when things go wrong, its amazing how easy it is to take it apart to fix the issue. Incredible job by the Chinese.
Variable density TPU!?! Wicked cool. Thanks for sharing Stefan, superb video jam packed with insightful info... You rock!
AWESOME video!
I tried printing a PETG backing with PLA letters on top (chosen because I had black PETG & white PLA) but the PLA didn't stick, however I did find that TPU & PETG stick well together to create unique properties, giving a combination of TPU flexibility and PETG rigidness when changing filaments between layers because I don't have the MMU setup.
Super cool ! Cant wait to get multi head printer into my hands :D
Hallo Stefan. Amazing project! Súper fan of your podcast too
I don't think I've ever seen so much e3d in one video. Nice!
I am in awe! I am a pre-beginner, meaning I have a Dreamer NX sitting on my desk but I don't have a clue on how to use it beyond turning it on. I was unaware that it could be versatile to make useful things. My husband's gift to me is looking interesting. Thanks for sharing. 11/5/21
that look soo cool!!
Nice video! I can relate to "over-engineering"!
Another great video!
FYI You can export as a single STL and inside PrusaSlicer split into parts, or objects just to save time and keep the parts together in a file.
Fantastic project
Thanks for sharing :-)
First rule when you build a complex part : make only one instance !
Making multiple instances is only worth if you want to increase you production flow...
I was thinking the same, but: he got away with only one purging tower. This might have saved him a lot of material.
@@FireStorm81318 But also I heard it can help with cooling, when printing small parts.
I usually find mixing materials like tpu and pla don't adhere well but nice to see a setup handle that. I'm going to try again.
Nice! I've got tool 4 spare on my Toolcanger waiting for the Hemera to come back into stock and might try these as one of the first flexible projects.
Good choice! Hemera will be back tomorrow. The toolchanger seems to handle direct driven tools quite well.
Gorgeous design and video as always :-)
Thank you! Cheers!
I'm too envious to watch until the end.
It could be used for anatomical models / surgical training models. Pla for bones, TPU for muscle. Other ideas: Sandals. Mechanical buttons or keypads, maybe even including conducting filament as variable resistor. And of course, food printing would benefit from having multiple effectors. Deposit sugar paste in a layer with one toolhead, then flame it up with a heat gun.
Loved it... I would love to see this possibility on other multi-Material tools like the MMU2! As usual.. Great end results Stefan! 👏👍
Like he said, multi-material printers that use a single hotend are only good for printing multi-colour of same material. I did some tests on my MMU2S and found the same results www.antalife.com/2020/07/project-just-how-multi-material-is.html
Thanks for the great video, Stefan! One thing you should know, I had originally watched this on Lbry and there's no way to Like or comment, naturally I subscribed.
So jealous of all your snow!
There is more to come tonight! It's currently really winter wonder land right here 😀
Awesome! I would like to use a 3d printer with a tool changer!
I've never thought of using overmolding techniques to get incompatible filaments to stick, I'm definitely going to try this using my chimera with PLA and TPU, as well as PC and nylon.
This is one of those things that first appears to be a solution in search of a problem because foam tape would be easier however like you point out this could be used to do way more complicated things that would be difficult to do any other way.
Well done
Thanks.
It'd be interesting if slicers could create an "Material Interface" setting that allowed you to weave layers instead of manually having to create a draft to lock it in.
Basically you could configure the depth the weave extends into each material, in a case like this you could have it 0 into TPU but have it go a few mm into the PLA, and then when it goes to print it alternates which material prints each layer in the zone created.
The layers would probably have to be solid in those areas but I bet it could give a very tight bond by the end and decrease the need for manual modeling.
Might be a neat feature in PrusaSlicer if Prusa will really release a Toolchanger as well.
I never thought like this way to make a hook before
We need a video testing interface strength/compatibility of different materials! :)
I can't wait until Prusa makes cost optimized tool changer. It really feels like the way forward in additive manufacturing.
Awesome! More tool changer content! Would be awesome to know which materials do, and don't work together in this process.
Great video Stefan! I really enjoy the parts where you talk specifics on slicer settings for projects. I just did a video on the same little Among Us dude in multicolor haha XD Thanks for sharing footage of your tool changer in action!
Super video
The new Cura has a feature of blending materials into one another so they adhere just perfectly! Even stuff that totally doesn't stick at all, like PLA and PETG!
I think there are many things to think about with a toolchanger. I would love a tool that goes around a 3D print in an exact way, removing stringing and maybe even support material. Just one thought.
That's cool. Great
For the palette, I was able to print TPU (75A) and PLA but I had to change the spring on the palette for the TPU since the spring the unit came with was too stiff. It then worked fine.
I clicked on this video when I saw it in my recommended. I still have no idea what is it’s about but I feel so much smarter now
Happy to hear that 😉
I'd be very interested in seeing some experiments with laminate/composite test hooks. exploring whether two or more plastics with different mechanical properties could complement eachother.
Multi Material, and dissolvable supports!
and of course some aesthetic things, because why not. (=
The tool changer is not only great for multi color/material prints. Even when using just one material; swapping ABS for PLA or another lower temp. material is not always as easy as I would like. Sometimes swapping materials results in clogs during printing. Also for production cases a tool changer is great. The ability to just grab another tool and then clean the clogged one while you are printing the part with another tool is great.
Time to geek out!
🖖
Guten Tag!
a toolchanger in my opinion is primarily useful for "not minding the amount of filament left on the roll" - if the software allows to automatically switch over to the next extruder if the roll is empty.
i personally do not like "stehrümchen" in questionalble design, but i need a lot of PLA for technical mockups.
I also noticed the "avoid crossing perimeters" doesn't really work in PrusaSlicer. I will try Cura next, somebody on forums suggested Cura does a better job at routing in general. It should make the stringing easy to remove by making moves outside the part, not just avoiding perimeters. I am happy both PrusaSlicer and Cura are open source projects and they are available on Linux.
This is dope
Lovely over engineering at it finest ! Nice Wanderschuhe :D
Try Superslicer. Enabling Ooze Prevention in Expert mode creates a 1 wall "skirt" around the parts. I think that's what you're looking for. Your profile for Prusaslicer should import since it's a fork. More settings to tinker with as well.
During the last days I tried to work more with SuperSlicer due to those additional options. I'll see if that helps!
If you design the PLA and the TPU model to be overlapping then Cura will generate an interspersed pattern which makes the two hold together with a lot of friction. In the future some other patterns will be automatically generated to afix two models of incompatible materials.
I'm creating a revolving hotend for my cr-10 to be able to do stuff like this, as well as having a layer of expensive material for the outer wall and cheaper same material on the inside.
It would be really cool to see one toolhead used for laying continuous carbon fiber like markforged. So it gets embedded within pla or nylon
In cura by using only two perimeters and adding an "extra infill wall count" you can have 3 tiered speed control to your perimeters adding a lot of strength and if you lower infill percentage to 10% or bellow one can reduce print time to 2 perimeter speeds and almost the same material usage and using my calibrated fingers and forearms seemingly no strength strength loss.
Printed spheres sound like golf balls hitting the concrete
Fyi, if you make a skirt as tall as the part you can get an ooze shield in PrusaSlicer. Uses a bit more material, but still works great for one part. Glad you got the purge block working, it didn't work well in 2.0 ish but ended up not mattering for my IDEX as parking the inactive nozzle over a silicone rubber pad stopped any oozing when inactive and PrusaSlicer sequences retractions during a tool change correctly. (something Cura fails at for some reason...)
this would be brilliant for making RC tires in the same way. I'm currently making wheels from 98A TPU and casting softer silicone rubber onto them with 3d printed moulds and this method would save me a lot of time
Dang - isn't this the usecase for the router tool? Could have been cool to see that used.
I did something similar with the creator pro and its dual nozzles.
Nice!
That printer and the variable hardness TPU gives me an idea for custom insoles for people with foot problems. hard PLA or PETG for the arch support, TPU for the padding... im sure some company is already doing it, its too good of an idea.
Please show more of this E3D machine! Also I thought hemera was ideal for flexible because of the shortest extrusion path. Why not???
It's working great for flexibles just had a couple of extrusion problems from time to time with TPU and that's why I changed to the OmniaDrop.
I have both the Henera and Omniadrop and I never had jam or failure with the Omniadrop, but the Hemera did have some issues. Plus the Omniadrop is easy to maintain and the whole extruder assembly much lighter than the heavy-as-a-mercedes Hemera.
I would love to do that to print objects that work like clothes hanger. One part is solid and another one springy to make it move or robot legs with tendons attached
@CNC Kitchen have you done any other videos on the e3D toolchanger at all? I'm curious to use it as an experimentation platform for multi-material printing with TPU and also introducing inserts
I look forward to more projects like this once the multi material becomes more common with the XL
This looks very interesting. I am curious, I have a printer with dual extruders and dual nozzles. could I do this with that printer?
An awesome thing to do with a tool changer printer is maybe make a more intricate design of conductive print.... would it be possible to make a print with a pcb integrated into the print, or maybe use conductive filament traced inside of a print... I thought about doing something like that with an hour device to prevent tampering and misuse.
Have you heard of self folding 3d prints? It works using a PLA layers and a TPU layers, that when placed in hot water, creates a bend. Look up Thermorph if you want to learn more. I would love to see you try it
Edit: Looking up Thermorph might not work anymore so I posted a better link in the replies
that sounds really interesting. I think that would be a great video :D
Never heard of it. Can you share some good links?
@@Audio_Simon Unfortunately the official research page was owned by square space and got removed but this hackaday article has the link to the paper. hackaday.com/2018/08/27/self-folding-origami-from-a-3d-printer/
@@arvindmahadevan9337 I’m pretty new to 3D printing but I was thinking along similar lines this past week. I kept having a print in PETG fail after the first couple of layers... but these 2D junk pieces that were left over were very flexible, quite strong, and decently transparent. There must be some really nice use cases for even that.
After watching your video, now, I really want to get and build a tool changer...
For this, I may use rubber and some addhesive :)
could bonding without the purging of the inner nozzle improve? Oh great video I hope you got some time off for the family bits. Worth it.
Hmm. Did you try wrapping prints in kydex? I just made a little bicycle bashguard from kydex n rubber. I imagine a flexible or crash structure from 3d print below kydex could be interesting
Wouldn't you get something like the ooze shield if you ask the skirt to be as high as your print and maybe 2 perimeters thick? Or the shield that goes around all the parts including the wipe tower does not do what you need?
PrusaSlicer may not have an ooze shield option yet, but a draft shield (under Print Settings > Skirt and brim > Draft shield) is somewhat similar, but a little less material-efficient
Tried that, but that unfortunately goes around all parts in a convex shape, which doesn't really help a lot.
It makes more sense to me to use multiple tool heads to drive large nozzles for fast printing while retaining a small nozzle for fine details on the exterior.
It could, but tool changes take so long that a lot of time is eaten by it.
^^ ohhh da hat jemand aber ordentlich Kehrwoch gmacht! xD
Haha stimmt
look up the enraged rabbit carrot feeder its a great multi material project that is actually propperly thought out unlike things like the prusa mmu
Additive technique is what used at stratsys where three d laser fusing powders
