My recommendation: Thunder Below! by Eugene B. Fluckey
VarioShore TPU contains a blowing agent that will foam up this 3D printing material during printing. This leads to a lower density of the material and also a significant increase in softness. Let's find out how well this material really performs and how it's hardness compares to other 3D printing materials.

While I liked the subscribe in this video, I think you missed out on a perfect "smash that like button". Lol
Ich habe eine Idee zum Drucken!!!!
Und zwar ein Volume Spacer den man in eine Federgabel einsetzt.
Ich würd gerne jeweils 3stk von von jeder Temperatur bei dir Kaufen um dich auch etwas zu unterstützen, selbst wenn ich keinen 3D Drucker besitze oder gerade deswegen =)
die Zylinder sollten 30mm im Durchmesser und eine höhe auch von 30mm haben. Infill so wie in den Video gezeigt/ verwendet. Ach und in der mitt eventuell ein 5mm Loch hindurch
Bitte Antworte mir auf den Kommentar wenn Du Interesse hast, dann schreib ich Dir eine Mail nochmal =)
you should try the lay-fomm 40 filament! it seems very similar to this, and i'm curious as to which one would be better.
Hi! Maybe you can test and review Facilan C8 and HT? Quite interesting materials out there :D I am glad that I found your channel, a lot of interesting stuff.
Perhaps also very interesting for thermal insulation in a print.
Good idea. Just beware that decomposition/burning polyurethane creates highly toxic gasses.
Could be a nice idea. Just don't forget that it's still a thermoplastic and doesn't have the same thermal characteristics as regular PU foam
@@henrymach I am also wondering what the thermal properties are. Of course for lower temperatures (below 100c). Then you could incapsulate the soft foam part into harder parts depending on the print temperatures.
Very good point. The closed porosity should give you great thermal insulation properties.
@@CNCKitchen Doesn't Regular TPU not already have a pretty good insulation property?
Perfect pronunciation of "al dente". Thumbs up!
Mille grazie! 😃
excellent insights, as always, excellent video Stefan! 👌😎
I like your short vids!
Same!
Hey i'm subbed to both of you!
@@antonrickert9427 they are both amazing, right?
You are marsgizmo i am big fan
0:12 - Mitutoyo tools. This guy is not fooling around.
Sometimes it's good to know certain people 😅 I only want to generate the best results for you.
@@CNCKitchen I use a Mitutooyo dial caliper that is almost as old as me, my dad got it around '85. Still as accurate as day 1
I have a Mitutoyo too. FYI it reads exactly the same as my Harbor Freight calipers 100% of the time.
This guys got calipers that cost more than my printer. I like it!
Worth every penny and I'll probably be able to hand them down to my kids at some point.
Make a paper airplane or a glider with the "lightest" version of the foaming TPU.
From the way he describes it, sounds like it's getting close to being 3D printer Styrofoam.
I love the benchy thrown into the bowl of water floating sideways haha
Perfect Storm in a water glass 😁
I’ve been using Varioshore TPU for a bunch of projects. It’s an amazing material, love the soft touch feel. Stringing / oozing is definitely a pain compared to other flexible filaments.
hey, do you change the temps during the print ? and if yes, i assume the temps can only be changed layer-wise and not for specific areas, i guess ?
@@mm-hl7gh the only way to achieve that is to use dual extruding printer with varying Temps in hot ends.
Mate this type of videos are so useful! I'm grateful that this kind of content is available for free. Keep it up!
I bought some of this about a month ago and havent gotten to use it because I wasnt ready to do a bunch of testing. Thanks for doing all the work for us and recording the whole process!!! Hahaha
Pretty amazing how the filament companies keep coming up with more and more interesting stuff. Great video!
I really appreciate the extensive and careful testing.
Good job Stefan as usual ;). This material is the best that we have found to build the big tundra wheels for our next rc bush plane project, not only because it is light but also because its softness provides a great shock absorption which is ideal to absorb the energy of hard landing.
Another great video, Stefan! As a mechanical engineer from a research institute I just love your scientific approach!
This investigation... was awesome! Thank you
I bought this filament because of this video. This video was so helpful. Thank you!
I DON'T EVEN OWN A 3D PRINTER, WHY HAVE I WATCHED ALL YOUR VIDEOS?!?!?!
You will own one soon
It is a sign
@@tobylofmark1084 I wish. Tiny apartment, single-dad... Some day, but not quite soon.
mood, also m o n e e e e (especially of all the filament i'd use)
Also just this channel's d a t a (so many nice graphs, and materials science tests)
This could be a good choice material for printable replacement headphone pads.
That is BRILLIANT! I was looking for some way of doing a 3D print with one end harder (for mounting) and the other softer (for application.) Now I can simply print each end at different temperatures.
Cool video! I appreciated the side by side comparison.
Excellent as always!
Its so good and informative i love it thank you
The black foam looks very nice to me!
Can you "post expand" the fillament? Eg: use a heat gun or soldering iron or oven to expand the TPU only in spot locations after the object has been printed?
That could be interesting for gaskets
I doubt it because the plastic melts at a lower temp than the foaming, so to prevent the structure of the part from being ruined you would need to enclose it but then there'd be nowhere for the gasses caused by foaming to go.
I thought about that as well. I'll see if I can find an interesting application for that.
Yeah, so there is potential risk that high temp. conditions will impact initial part hardness properties over time ?
I think perhaps a CNC laser might be appropriate :)
This is pretty good concept
Cool stuff. Thanks for video!
As soon as I heard it's closed-cell, it made me think of the perfect application: custom storage insert for breakables.
I love to see innovation.
Smart. This is what I consider innovation.
Weren't you the guy to help me bump the ability of my X1? And now I'm still learning from you? Fuck yes.
That's crazy how it foams up with different temperatures! I've been experimenting with printing TPU in vase mode with some great results, most useful print was some transparent TPU grips for a mini desk vice, printed on-end. I figured if you make the object 0.8mm thick then it can be printed entirely in vase mode.
This guy made the hardware stores sell a whole lot more concrete slabs than ever. I bought mine before even the printer!
I wonder how this TPU would adhere to a harder material like PLA.
I'm thinking about variable shock absorption between hard layers.
I've had reasonably good success making two-part designs with a PLA base, a filament change to TPU, and finishing with the TPU. I've also used PETG - in that case, I had to change filament at a point in the model where I could maximize the contact between PETG layer and TPU layers above it. While changing the filament, the temperature has to be lowered quickly for the TPU or else it is very stringy. Some custom gcode similar to that used in temperature towers was sufficient but I still had to wait before inserting the TPU so that the printer didn't resume printing until the nozzle temperature was lower. Not an ideal way to go, but the parts worked OK.
Genius stuff, thanks
Super interesting! I've been able to print original NinjaFlex, which is 85A, on my CR-6 SE, but need to obviously go incredibly slow (15-20 mm/s), and need to completely disable retractions. Intrigued to give varioShore a try based on this, as it could theoretically give even softer results but be easier to print. Thanks for taking the time to do proper testing and publishing the numbers, incredibly helpful.
FINALY SOMEONE WITH SKILLS
See's Maker Muse's video on the CR-30. See's this... and the portion on "does it act like a sponge" and my first thought is "why do I want to print a pool noodle?" Glad that of all the channels that looked into Varishore and LW-PLA, it was this one. Better then "hey, it's pretty cool. Look at this model!" and to have actual methods and data behind the tests.
Awesome idea!
Great video Stefan. I like the look of the colorfab temperature gradiented test print you show. Where can I find that?
Very interesting !... Could you do a strength test at different temperatures too ?
I'm curious about layer adhesion with all these bubbles...
I'm going to print me some coaster for my glasses with this filament
only CNC kitchen would actually have friends at Mitutoyo! They make great stuff and I am surprised at their generosity.
Cool! Ordered two spools… 😅
Yess finally too print a personal "flashlight"
Stefan, another amazing review. How do you print multiple models at different temperatures? I understand how to change temperatures at height/layer. Do you pause at height/layer, manually adjust the nozzle temp, then resume? Or is this a custom script? I apologize if this has been asked and answered already.
Hey Stefan, thanks for your videos! I've learned a ton from you. Question: Do you have a calibration process that you go through when setting up a printer or new filament? For example, how do you make sure that a .4mm width, .2mm high line actually comes out of the printer at those dimensions?
Have you thought about using the plaster used in metal casting to remelt printed parts?
That indeed looks promising, especially the buoyancy. Guess I'll get me a roll of that stuff and then let's see what kind of stuff I can come up with that I could use for e.g. kayaking. I also wonder if you could use it for applications where you'd normally use rubber, like a holder that slightly grips on to things like e.g. guitar picks. Pretty interesting, indeed! Thanks to checking it out in your usual, very thorough way
That slap scared me
brilliant!
Great video!
Awesome! First use case? Built in hinges in a single print without swapping filament? Second? Sturdy box with soft outside or inside?
Warmest belated congratulations on the birth of your child! I wish you guys the best!
Thank you so much!!
Super helpful. Thank you! Were you varying flow rate at all? What flow rate were you using with 220 degree nozzle?
where is the sub model ? just asking :D nice video this was really informative. again!
Red Storm Rising is an amazing book.
WOOOOW thats cool
I'm wondering if you're onto something with the bubbles deflating with the hotter temps - but I would say it's probably on the external surfaces of the filament, because I run production parts with ~1-1.2mm widths and they get softer right up to about 245c - so maybe the extra volume vs surface area plays a part there - maybe try it on a larger nozzle and see if you fair the same.
And yes, definately a closed cell foam, I've used it for outdoor/wet applications for 12 months or so, no problems.
Im suprised how far 3d printing has come.
Hello Stefan. First, thank you for this test/tutorial. Is very useful! :)
I want to please you if can you explain me how did you change Extruder multiplier in the same print on Prusa MK3?
As somebody who has stuck to PLA because Ender 3, this is really exciting stuff
This could make some really cool soft body fishing lures.
Higher temps will not increase bubble formation, but it does reduce surface tension, allowing more air to escape and off gas. Therefore, if you print too hot, it becomes less foamy.
hello back, shtefan. I feel welcomed.
A silly question, perhaps, but would the ~60 Shore D of your cutting mat have affected the measured results of the test pieces? Shouldn't they have been tested on a hard surface?
I printed a handle that I wanted to be soft using TPU at 220 C. There was some softness, but the handle was about 6 cm thick.
Dude i print Filaflex A60 Tpu with a standard predator and it works real good
would you say this could work for prosthetic props instead of needing silicone?
Do you think this would be a good material to print a water tight gasket or O ring of sorts out of? Looking to pair a 3D printed gasket with some dielectric grease to seal something and I feel like this printed at around 65-70A would work great
I've been fooling around with loose infill patterns to make ordinary PLA quite "spongey". Just varying the different degree offsets on Cura's "zig zag" to something like 0,60,120,30,90,150 leaves you with a mesh that doesn't overlap with itself very much. It also makes the material blob and then string at crossover points, which seems to make it even more pliable. It looks like lace.
Bet this is great for making compliment mechanisms by turning the temperature up in certain areas to bend
*compliant
Schande über mein Haupt ... ich hab den Tip mit dem Infill beim ersten schauen überhört 🙈
Aber wie immer ein super informatives Video, mach bitte weiter so. Danke!
Mitutoyo is probably disappointed you didn't use a firm surface to begin testing with. But since your cutting mat was used for everything it's acceptable.
Damn, good point. Though I'm 99% sure that it doesn't matter for shore A at least.
Hello Stefan,
It is very interesting. TPU material is hyperelastic material which is non-compressible when it is in this bulk form. This property is obviously lost when add air bubbles inside. It could be very interesting to use tour universal tensile machine to investigate this !
If one thinks in term of small strains (and not finite strains) it means that it is not only the shore value (and thus the apparent modulus) but also the value of the "Poisson coefficient" even if this is improper in finite strains. So the applications could vary as incompressibility is often and advantage or a drawback. I think it could be nice to investigate !
I hope I will find some time to investigate tensile test on this !
Best regards,
Thanks for the comment! I'll keep that in mind. There is still a bigger TPU test outstanding.
Fantastic video! Stefan makes super videos all the time but this video had to be made by colorfabb year ago... most of the filament manufacturers just push out a new product without giving enough information sometimes they forget to provide proper data on how to use the product.
could one use variable softness within a print to create improved sound-dampener-thingies since the different densities would absorb different frequencies - I'd assume.
For example 3d printed acoustic panels or speaker stands
Or feet for a 3d printer
you need to do a mechanical test for this, i need to know how much it stretches and what layer adhesion is like
Do you think this product could be incorporated with prosthetic creation? Looks promising.
Interesting material. :)
Well, whether you got a direct extruder (please, dont' mix up with "direct drive" !) or a bowden extruder, I guess it should print if the filament path is constrained all the way.
Something "special" about this filament is the relationship between extrusion temperature, extrusion multiplier, and final surface look. Number of print profiles can be pretty daunting.
This material is so special you shall have very specific demands to use it. If something has to float, it's the way to go, though.
Hello Stefan,
i have just seen your video about the varioshore TPU from colorfabb. do you think this could be the right filament to print grips for sim racing steering wheels?
As a fan of Colorfabb, unfortunately, I had to abandon them since they have restricted their shipping to DHL which means that a single roll of filament + shipping costs me around $70. Switched to Esun recently since I simply can't go with ColorFabb anymore.
On-topic, awesome breakdown Stefan!
could something like this be used for a 3d printed textile? like modify it into open bubble foam to increase air permeability and make the print "breathe" better?
Can you vary the hardness mid-print to get movable parts like hinges or something similar?
We use it for custom gaskets all the time.
I wonder how the flexibility degrades the life of something that flexes a lot. Bend a 3mm plate 100 times and analyze the physical properties. Does this material absorb moisture or does it need to be dried. I could see making ink stamps with such material.
How well does it burn? Thinking lost foam aluminum casting 🤔
But if you squeeze the print underwater, will it absorb water? Even if the bubbles are separate they must be able to absorb water because the bubbles open up to release the air when the print is pressed.
Would be interesting to test it on a CHT Nozzle and see if the cutting allows even more softness
At what speeds did you print? Did you set one speed for all types of motions since the whole system is speed dependent?
I would really like to see if its possible to print shoes with this filanent that is atleast a lil comfontable
How bouncy can this material get? I'd love to see energy return measurements.
Interesting!. I've just picked up a small hardness indicator, that has a 2mm ball indenter made for soft materials .it is marked B.S. hardness RABRM meter . It functions the same as the analogue mitotoyo shown. Anyone know what it was used for?
I would love additive foam pattern making for lost foam casting. Not sure TPU would work.
can cura by itself change its temps (and maybe even speeds) during the print ? best would even be not only changing by layer, but also by area (?) is that possible ?
What nozzle diameter did you use? I just printed with .8mm at 230C, however the result was not very soft.
Maybe it's not related to the nozzle size, and I just had too thick walls and too much infill for the small part I printed though.
It's a shame Mitutoyo only let you borrow those hardness testers. :P
Although, I can understand why- guessing just one of those probably cost more than most of your printers. haha
He has an e3d toolchanger with 4 extruders that costs about 2500€ ... just how expensive are those tools?!
I was curious about their prices and there's some for 400€ so less expensive than expected but tbh there's also some over 800, and I have no idea what the difference is.
Edit one of the ones used in the video is 487€ and the other is 838
@@imnota hm, that can actually get you a decent 3D printer.
If I ask kindly and you guys have interesting project ideas, I'm quite sure they'll lent me those a second time.
@@CNCKitchen While I'm not sure these, or any other tools are really made for it, I'd be SUPER interested in creep testing on various materials.
It's one property that has actually caused me problems with functional prints.
Would you make review of colorfabb brand new LW-ASA, and compare to LW-PLA?
I m curious, if RC models printed with LW-ASA will become more impact resistant. What are benefits of each ?
Just have seen that yesterday. Looks pretty compelling!
LW-ASA is more brittle in an Impact, there is a video on youtube were a guy compared to 3d prints in LW-PLA and LW-ASA. The LW-ASA shattered as it was glass, the big benefit is UV resistant and temp resistant.
Using the optimum foamed TPU and low infill how low could you get the hardness?
Excellent video!! 🇦🇺🤜🏼🤛🏼🍀🍀🍀🤓
I
i wonder if water logged TPU would have a similar effect. I know if gives terrible finish and pops and bubbles a lot.
What happens if you print at a low temperature, then heat the part up? Does the part brake or expand? Can you leave this stuff in a hot car?
