Please correct me if i got something wrong. Ask if you have some questions.
I made the same exact ring. I used a old handheld mirror from the late 1800's. It was warped and not worth fixing so i melted it down. A pure silver mirror from that era. So i said why not and came out with alot of silver. I did everything by hand and used a Dremel tool. Also poured the silver into a handmade moulding. Pure silver is definitely more softer than than sterling or any other cut/non pure silver. So i made the ring thick not quite as wide as this one in the video. But very similar and it turned out perfect.
just perfom FEA calculation and you get the results
Only possible if you know exactly which type of CF and resin they used. Otherwise it’s a guessing game and the results will be off.
whats the thermal expansion ratio of carbonfiber tubes compared to linear rails? I thought Titan is the jack of all trades cuz its lightweight ,stiffer and hast nearly the same thermal expansion rate.

I don't have a Voron but the machining is beautiful. Who did you make the Graubünden edition for?
Thanks! I grew up in Graubünden (east Switzerland) and we needed a name for a gray edition. Graubünden can be roughly translated to english with: gray alliances / gray unions. That’s why it got that name ;) We made it for people who want to set an accent in their printer with a secondary colour while saving weight on the gantry.
@@premiumbasics I'm also from Graubünden. I don't know many who have printers here, that's why I was asking😅. Really cool project. I'd love to build a voron but I haven't used my ender 3 enough to justify it.
Nice! Building a Voron is a fun project, even if you don’t use it all that often :D Mine is sitting around mostly waiting to print packaging material…
@@premiumbasics yeah the building part is the most fun. My FPV drones are expensive enough tho...
Damn, I already purchased one from you directly, but having a blue version, where it's written lac léman ?! I am on the edge of buying a new one ! just to make sure, is there another difference with the other version ?
The chamfers are a bit different and text is now laser engraved, threads are still at the same position.
too much jitter-jitter for my taste. I remember the first videos as this development started, and for something that's supposed to be stiff, a shaky video is kinda antithetical :)
I asked myself: “How many effects do you want?” The answer was: “YES!” I know the use of so many effects is probably polarising, but it was a fun project to do for me :)
words, words help
Where to get?

Although strength will be reduced, weight will be reduced if the linear rail is machined to reduce the weight ; the outside edge are the main parts ??
Ok, thank you, was about to post the obvious fakery in this video, but you admitted the aluminum is already deflected at the beginning of the 81c test. BUT this still doesn't make up for trying to mislead by showing '0' deflection for the alu beam at the start of the 81c test. You know you should have zeroed it against room temp. 'bed leveling' isn't an excuse, if it is 1) WHY do these tests at all then?? 2) as you know it's a wildly imperfect solution at best, no printer is going to perfectly compensate for a complex catenary shape, you know this too.
I'm not an engineer or expert but hands on. There are high temperature resin systems and that tube didn't use them. A part that would pass this test could be made with pre-preg materials and standard industrial practices for them, within the Aerospace industry. You'd need an autoclave, data logging, refrigerated storage and a bunny suit clean room to get it done with consistent results over any significant production schedule or period of time.
Hy. How can we get in touch with you?
Discord, Username: premiumbasics#0 hope that works for you.
Excellent Job. Just one cmment: You are measuring deflection of the beam + the linear rail in the z axis. As the weight of the printhead is more or less fixed. I don't see the importance if this piece of data. Also, the printhead can be as light as 200 grams. What would be nice to see is the deflection in the Y Axis. This is because in that beam the load will vary depending on the acceleration and deceleration. The linear rail should be also much stiffer in the Y axis than in the Z axis.
Super short/generalized explanation for the creep with the CF tube: In static loads metalls, up until the yield point, behave pretty much linear elastic, meaning that the deformation only depends on the internall stress and will reset to its original shape when the load is removed. So temperature (within reason) doesn't affect the deformation. Polymers are fairly different in this regard, they behave in a visco-elastic fashion, meaning that the deformation depends on the internall stress, time the stress is applied for and the temperature of the material. The deformations occuring because of the time and temperature effects also do not reset, this is what you call creep.
So the epoxy, which is a polymer, behaves in a visco-elastic fashion? But what about the graphite fibers?
@@mckenziekeith7434 not a 100% certain but since carbon fibre is basically just thin strands of Graphen they should also behave in an linear elastic fashion. This doesn't really have an affect on the part strengt since the fibers need the polymer to transfer loads from one fiber to the other. Especially when its anything else than straight pulling. (you can't really push a rope)
@@swisshoumi in a composite, and assuming that the load is aligned with the fibers (which is not always the case) the fibers bear the load, both for compression and tension. The binder (resin, in this case) mainly just holds the fibers in place during compression loading. The compression strength of epoxy with graphite fiber is much greater than the compression strength of epoxy alone. And the compression strength of epoxy with graphite fiber is much greater than with glass fiber, also. In the case where composites are subjected to load aligned with fibers, I am not sure if the visco-elastic properties of the resin can explain creep. However, if the load is not aligned with the fibers then it would make sense, because the fibers would be trying to displace the resin matrix as they are loaded.
Your work is excellent and I am very grateful to you, but I have missed the third contender, the original kits aluminum bar
Heating CF tube to unrealistic value of 80+ degrees knowing that it's resin can handle as much as 85 degrees at most is basically a misleading marketing, absolute majority of printers will never exceed 65 degrees chamber temp
Heyho, I am curious about the status of these ultralight beams. Do you have an estimate of when we can order them? I am just waiting for one of those to rebuild my V2.4 😅
Hi, thank you for your interest in this Beam! Mamabot and I make them during our free time and had some busy months… Right now I am focusing on my Granite CNC project. Please don’t wait on our beam with your rebuild, I can’t promise any date since the upcoming months look busy too…
@@premiumbasics Ahh alright, thanks for the reply. Don't stress yourself too much. Take time and make it perfect :)
Are you (a fellow) Swiss? I think I might hear a slight accent there... ;)
Yes :)
Have you considered putting holes for the Lightweight Labware extrusion backers on these? I'm sure that would drastically increase the stiffness while keeping the part lighter weight than just a 2020 extrusion.
I’m hoping there’ll be a MGN12 version
The resin that is used with most commercially available carbon fiber is not meant for high temps, basically it's a plastic that impregnates the fibers and plastic doesn't like heat in general. There are high temp pre preg and epoxy resin options available but cost more. Are more difficult to work with and in general are not going to be found unless special ordered. Also, probably would help to have unidirectional carbon fiber but they never do that cause it doesn't look as cool ie the 2x2 twill pattern
Did you do any finite element analysis on the xbeam design.
Yes, but the results were way different on the FEA, maybe I made some mistakes with the parameters there…
Is this using continuous fiber or chopped fiber?
Continuous woven CF as far as I can tell..
Nice to see some more swiss youtubers ;D And great work :)
Thank you :D
CF is more expensive then Aluminum
yes you should do a test with 60C on that CF tube. The main reason why it deforms - its resin, and resin become soft in 80C like pla in 40C (its just a similar point, these are different materials and resin is not thermoplastic like pla, so just keep that in mind) also, the problem with high accelerations and direct extruders are: heavy top, lightweight bottom, so not only deflaction but also twist comes to the game and things are worse and worse. best idea <yeah that hurts me too> is a thing like bambulab did. motor between rods with reduce twist (yeah I gladly see that test on 2 steel rods becouse some guys might be suprised!)
I'm sorry but these tests are no valid because the different structures of the beams!Try with a square aluminium tube as the CF one and the results will be way different or make a sophisticated shape as the AL beam with the carbon fiber one.
Regarding the deformation of the composite, aluminum hard points are typically embedded in the layup for bolted connections. In this case where the part has been manufactured, you should slide in aluminum spacers and use longer screws to grab both sides of the tube at each bolted connection. I expect you'll see slightly less deflection although it comes with a weight penalty.
A lot of carbon Fiber stuff is done with Epoxy resin as binder for the fibers. Most of the epoxy resins are only stable up to 60 Degrees celsius. Starting at that point, Epoxy resin starts to decompose. Cracks can be formed. There are some type of resins that are more stable to higher temperatures, like water based Epoxy resins. Which go up to 90 Degrees. But water based ones do have a lot more pores. Not the best choice if you want to have high strength. And other High temperature resins are quite expensive. For a heated chamber you should know to which temperature the resin is resitant .
***laughs in SR-71***
@@CaptnWaffles sorry... I don't get the SR-71 comment.
the next step could be an extrusion in which the track is an integral part of the extrusion, perhaps made of 7075 aluminum and hard anodized
It would have been interesting to see how it would behave after heated an weighted and just let it cool down with the weight still on.
I actually am an engineer and during my college internship worked with carbon fiber composites for the aerospace industry for about a year. The main problems that stand out to me unless I am completely missing something is the resin used in the carbon fiber tube. When laying up carbon fiber there are two types of resin used thermoset and thermoplastic (think heat activated epoxy that permanently sets and 3d printer filament). Both have uses, benefits, and negatives associated with them but in this application it seems clear you would want a thermoset so that the temperature would have little to no effect on the tube. It seems that this company used thermoplastic probably because of cost, layup, and curing which all tend to be lower and easier with thermoplastics.
Thank you for sharing your knowledge and experience with us :)
Seems kinda biased if the seller of a high quality product compares his own product to a low quality product. Aöso the Temp is somewhat strange. At 80°C no "normal" Filament benefits anymore from it and its to cold for performance stuff like peek. But at 80C you already get problems of demagnetization, lubes not working properly anymore, electronics gettign to hot... But its the temp where Carbon made with normal resin looses stiffness the fastest. mysterious.... Maybe next time you should take a same quality carbon fiber tube and a reasonable temp for comparison. In this form it just looks like an advertisment amde to look like a objective test
Thanks for showing! 2 things I’d like to see: a comparison to the stock 2020 extrusion, and input shaper results for each one. I tested the FYSETC aluminum lightweight x beam agains the stock one in a similar fashion as you did. I found the stock x beam deflected about half as much as the FYSETC lightweight beam. The inputs shaper results of the FYSETC were also worse.
Interesting results, do you happen to have the numbers when compared to just a standard aluminum extrusion profile?
Not yet, need to get my hands on one and will report back once I tested it :)
i wonder whats the price of alu x beam?
The 350mm anodised version will be around 100$
@@premiumbasics thats a nice price to be honest, what do you think of adding holes on the back for titanium backers for more stability?
At first i see that the cf tube very much outperforms aluminum but as people here said, the flatness can be weird? So if we could find a way to machine carbon flat and use it in this way, it could be used reliably. Edit: carbon is actually a machinable material. I assumed coolants (or heat) could screw up the resin but i don’t know much about real cnc.
THere is a very wide range of carbon fiber products, with a wide range of material properties. This tube is likely a cheap mass produced extrusion or sleeve molded part, using low quality (probably polyester) resin. Hand laid and vacuum cured carbon fiber using the appropriate epoxy will be significantly lighter for the same stiffness, and will be more resistant to temperature (100-300 degrees C typically I believe, depending on the epoxy), and can made very flat and straight, but you're looking a hundreds of dollars instead of 20. And yes, real carbon fiber is easily machinable with teh right tools, and will resist most coolants pretty well.
Have a look at e3d toolchanger x axis. They put a lot of work and time just for that.
Most cheap CF tubes use resin which can withtand temperature up to 60C. More expensive use higher temp resin.
I am so humble! We do not deserve this great information for free. (of course it won't be free - when I order a beam when it's back in stock). I have been doing a lot of CF. And the resin has a lot to say. The "optimal" Carbon fiber tube would be a molded (could be made flatter than a beam is machinable), prepreg tube with a high temp resin matrix. This is absolutely doable. And it would not get the same sag, and the modulus of stiffness would also be higher over the temp-range. But is it easily available - no. Is it worth the hassle over buying your beam - probably not. But doing as above, gluing the rail with a high performance 2K glue and removing the mounting HW afterwards. It would be possible to achieve lighter weight, the stiffness would still need to be tested though. Awesome work!
Thank you for sharing your experience with us! :)
You and the team put quiet a lot of effort in this video. Thank you! Can't wait to hold the first 2.4 beam in my hands.
Well, this is one aspect. What about the ringing shown by anyone that has recorded a before and after adding these alloy lightweight gantrys? Any i have seen doing input shaping and accelerometer results with the alloy gantry has been considerably worse after the change and removed the ‘upgrade’ cf will show much better damping as well.
I don't think "damping" is what we need on a gantry because it mean we are loosing accuracy. Due to the damping you will introduce smoothing inside your move that will result in loose of precision.
@@hman72y that sounds like a thought bubble … not only was the fact it has some damping at high frequency an aside at the end of my comment. Having some damping is a hell of a lot better than having uncontrolled resonance …
@@hman72y if you think damping = bad, better not build a voron. The gantry connections and hotend/extruder mount design is specified to be built from abs with 40% infill. Plenty of damping there.
And input shaping is literally electronic damping
@@jeremyglover5541 I admit I'm more following VzBot than Voron ;) Did not know their using damping on voron as on VzBot they try to use Aluminium part
Would love to see the results with the linear rail on the side vs the top.
Awesome video! fantastic demonstration and very rigorous approach! I love it! One thing I would like to see is how behaves the Carbon Fiber tube in a 50-55C environment which is where most desktop printers with enclosure will operate. Oh, and also cost should be factored in the equation I think. Kudos to you for this great video! Thank you!
Thank you! Love your Videos btw! Yes most will print at 60° max chamber temperature, maybe I do a test in the future with these temperatures. The CF tube is around 34$, our X-Beam will be around 100$ for the anodised 350mm version. As said, the CF tube is probably the better option for most.
try it again when the rail is horizontal
You discovered something important. Principle shear stress is in the +45 and - 45 direction. In the first design you have 90 degree members in the shear web that can't transfer any shear force, other than through their own bending stiffness, which is very small. Make sure all the members intersect at the same point where they come together. It looks like you have some off set. I think a lot of the deflection in your beam is from the diagonal member flexing inward, not the whole beam flexing. Your screw mounting points should be located at nodes if the truss structure, not a middle of the members.
Nearly all the force on the beam due to acceleration is in the horizontal direction so you could design the beam to have more stiffness in that direction and less in the vertical.... or just less in the vertical to make it lighter....
