@@properprinting this looks very promising for light gantries (with carbon rods?) and yes you should definitely carry on with the project. Towards Open source/commercial frame-robot type things? Regarding the speed-boat-race me (and the mrs) were watching and talking about engineering principals. On a core-xy printer, surely the Gantry and head need to be light but the Frame as rigid as possible regardless of weight? Some people literally bolt their frame to the nearest brick wall ;) also... . I can see the benefit of triangles for maximum strength for the mass but could frame components be square (with internal triangular reinforcement?) for greater simplicity where weight is less critical? You'd only need 1 corner model :) xx

Now, this might not be the fast printing revolution - but it could bring us closer to a stable and economic 3d printed 3d-printer frame, which I'm all for. I'd love to see you pursue this idea further!

[@ButByAI]

Yes! It might become a cheaper alternative to exstrusions

[@bubblodetechmore5512]

Aren't extrusions already cheaper than that? It would be a different story if those blocks are injection moulded tho.

[@scienceguy8]

Even if this doesn't work as parts for a high-speed 3D printer, I can see this being useful as a structural component for building things like boxes and enclosures. I could see this making for a very interesting looking PC case, or as a replacement for those expensive aluminum extrusions you see on some printers (less cutting and drilling).

[@letsgetsteve]

Is it 100% the only solution? No, not even close, but it is pushing design and a new approach. I think it is incredibly interesting and think there is a ton of potential here. I would say keep working on it until you hit a dead end. It is a great way to work those engineering muscles and shares a new perspective approach with the community! Great work!

[@clabrop]

Hi, this is a great idea. Here in my country (Paraguay), it's really difficult to buy v-slot to make 3d printers, then you only can laser cut mdf or something like that. This idea can really have a great potential for smaller countries to promote building stuff. I would really love to see a full 3d printer frame made with this idea.

Great idea! The tetrahedron is the most rigid structure from geometric principles. However exploring the unknown means that a few failures are to be expected and this is part of the learning process. They usually allow to generate new ideas. Two things though: - for smooth movements you need smooth surfaces. - things that assemble will be heavier than something in one part as you need to generate extra loads to keep the parts together. I'm eagerly awaiting next episode.🤩

Things break, designs don't work out, unexpected problems out the wazoo, smacking my head at the wall for hours, days, weeks.

[@Rein-hg9in]

I think this is a great idea. You could build a "3d printed 3d printer" with this concept. And yeah, it looks freaking cool. Just imagine a printer built out of those. You just have to figure out a way to put a belt in there for xy and for z.... Well, you just put 4 of those rails vertical. Nice job man!

[@gyulaorszagh8403]

it's awesome to see someone finally utilize the triange. i just cannot for my life find out why everyone use square tubes and stuff, when the triangle has the best strength of every simple geometry.. but i'd make it simpler, less modular, and i'd make it with only 2 smoothrods at 2 edges along the triangle. also i'd print it in one piece so you don't have to tighten the modules together. can't wait to see how you'll advance with this project

[@leftaroundabout]

Well, it's not hard to guess, is it? People use square-everythings because it makes everything so easy to design in a CAD with a big cartesian raster. But you're right, that is not ideal. (And it's not like more sophisticated geometries would put the software to its limit!)

[@TalkingGIJoe]

you have to use what is available... lightweight triangle extruded shapes are hard too find...

[@littlesnowflakepunk855]

the other major reason people use squares in 3d printers is that triangular t-slot extrusions aren't nearly as common or available in as many sizes, therefore they're more expensive - and a truss like this would be even more expensive to mass manufacture

[@zeendaniels5809]

12:30 You look completely thrilled there! And I understand you completely: There's a satisfaction looking at your idea as something real, something you can touch, something you can use... No words for it 😁👌🏼

[@doughnut1107]

If you went with the hollow tubing, you could thread it on the inside to provide extra support at the ends.

[@mitchellstrobbe7779]

I definitely agree, smooth rods in the linear rail portion would definitely be better

[@timlong7289]

Or, you could loctite in some threaded standoffs (like the ones used to mount PC motherboards). I'm taking my inspiration from archery arrows - hollow tube with a threaded insert epoxied into the end.

[@tinyfluffs]

Definitely should try a carbon fiber tube on a micro-sized track roller. I love the direction this is heading in as a concept. Sure it's not the most rigid frame in the world, but it's definitely a cool exploration!

[@burgle66]

Your tenacity with these designs is completely insane... and sincerely inspiring. Plus yes, I would love to see you make a printer out of this system, or at least a working gantry.

[@lukassembol7542]

Yes, please, continue! When you ditch the thread, the printed wheels with pressed bearings should be enough for it to run smoothly. This could very well be the next iteration of reprap project. Just use 6x1mm ALU tube and tap for internal thread, and you're golden 🙂 The beauty of it lies in the minimal required tools - just tubing cutter, sandpaper and tap. This way you can eliminate the need for any saw or dremel with cutting disc...

[@OneLiterPeter]

So right off the bat I said to myself... Stainless Hypo-tubes instead of threaded rods. For reference, I've been a design engineer in the medical device space for the past 30+ years. As for lightening... Maybe a triangular beam that is not skeletonized but has gyroid infill, printed with one side on the build plate. That'll already make it as flat as the built plate, if it doesn't warp. I like this subject and I think you're on point thinking about the next step in 3D printing. As always, Awesome work! Thanks for sharing.

[@thorgersbach698]

Keep going with this idea, smooth hollow rods (carbon fiber, titanium or similar) with smooth bearing would make all the difference

[@thorgersbach698]

I also had the thought, for people who want formula one levels of performance you are looking at X price range but for others who are happy with the weighted version, the price is X

[@247printing]

How can I "...throw more Input Shaper on it..." - I want that, I need that, I love round corners :-D

[@eukaliptal]

Looks cool, I like that it's modular Ideas, use the hollow steel tube: 1) at the end use a long screw and glue with J-B Weld original(or your glue of choise) 2) use one of those ball joints used in RC for the stearing, insert the side of the ball into the tube, form the tube ends to make them hug the ball, add glue if posible. The threaded side should stick out and allow you to apply tension, you can choose from steel, brass or alum.

[@jasonwhite2775]

Try designing the segments to use 1 threaded rod through the center. Make the end segments a little more stout or a plate of some kind to allow more torque from the single rod and connecting points for the joint. For the corners, make them interlocking and completely round or what ever mating shape you want the rollers to be. OR 2 corners interlocking and 1 corner designed to hold a hollow tube for the linear rail.

[@jasontrauer]

This is a win win for everyone. It's entertaining, there is much to be learned through this iterative design process, and it's inspiring for everyone to see someone think differently and to approach problems in this manner. I highly recommend you continue.

[@digitaldragon72]

I would definitely like to see you pursue this idea/concept as this has great potential. It may ultimately prove to not be suited for fast 3d printing, but it will drive innovation in the industry and others that rely on motion systems.

[@BrilliantDesignOnline]

I might suggest rather than an enclosed triangle ⛛ , an equilateral Y shape. Tubular roller shafts (rather than threaded) should give a better weight to strength ratio; the receiving cups could be much smaller, and use CA glue for bonding lengthways. Have the wide of triangle down on flat surface, apply CA to upwards facing leg 'cup', drop in tube, which could be held down with a milled jig to ensure straightness and uniformity of pressure while curing. Ends of tubes can be tapped as needed. Not sure about the rest since I am only a lowly Ender 3 V2 use, but fascinating to watch your design progression.

[@ZeFoxii]

I would do this as a drop in replacement for a voron gantry. That way people can scale it up or down depending on their printers needs. I think a hollow steel tube would be best as you can then tap them and screw in standoffs. Keep going and make this a full build

[@sl_st]

Well done. buddy. The result is impressive. Really modular and very interesting, just like you told me earlier =)

[@kofferkulli]

I like the design! If it doesn't work out as a linear rail, I think this has potential for robotics as a frame. Similar to the currently often used aluminium extrusions. As you already suggested, tubes instead of threaded rods might be a good alternative. If the wall thickness of the tube is thick enough, an inner thread instead of an outer thread could be used to tension the stacked modules. This has the benefit of using a smaller thread than one would need for an outer thread. (Hope this makes sense) However, the tubes then need to be shorter as the stacked modules.

[@PhotonCast]

Yes! Watching your thought process and progression will be excellent!

[@EaSImpact]

Love, how it looks like! Thanks for the video!

[@MartinDanilo-mk7on]

This is my first comment ever. I think there might be a misunderstanding with light as possible. The static parts should be as heavy as possible. Different materials should help with dampening the vibration. Only the moving parts should be light and stiff.

[@properprinting]

True that! This reminds me of a video Tom Sanladerer once made where he filled his extrusions with sand. Maybe I can make closed segments which you can fill up xD

[@MartinDanilo-mk7on]

Yes, I always thought Tom is called SANDladerer ;) he should have left out the moving parts.

[@tslee8236]

​​@@properprinting You can refer to X1C's implementation for inspiration. It may save you some time. By the way, Winston Moy did the same with a Shapeoko CNC 3 years ago. You can find it on his channel.

[@tslee8236]

Yes. The static structure must be able to absorb the forces generated during acceleration and deceleration. A heavier structure will reduce the magnitude of any vibration. I vaguely remember someone suggest using magnets as dampeners. The generated force can be minimised by reducing the weight of moving parts in the first place. Another thing to watch out for is the natural resonance frequency of the moving parts. The printer's frequencies of speed changes should not overlap with it.

[@kittrelleberwine]

Id love to see this scaled up. Doesnt seem like the best option for going fast but still could make building large printers much cheaper. For example a 500mm sized printer, would be great to see.

[@timkn6147]

Don’t get discouraged! There is no innovation without frustration. I personally enjoy watching your progress.

[@ChrisHarmon1]

This is an awesome idea with excellent implementation. I think instead of buying 100% threaded rod we should try to find some smooth steel rods(think Prusa style linear rods) that can easily be threaded with a DIE. Ideally sizes that can threaded directly or by just removing the surface finish/chrome with a file/grinder/belt sander. I'm picturing some sort of bearing harness that allows you to rotate it easily to get an even finish for threading with the DIE. If it catches on I'm sure China will eventually sell cheap pre-threaded rods but until then I personally would prefer stronger smooth rods over 100% threaded. They would likely be more concentric as well.

[@alexhills8149]

it is amazing how fast you have grown! Congrats! you earned it! Keep the cool projects coming!!!

[@ericblenner-hassett3945]

YES! More Videos!! You are on the right track, for the scale look at how to make the trusses with hollow tube without becoming breakable. I believe you are on the right direction by making them like Lighting trusses.

[@JernD]

I like this idea, but I don't think that printing them in small segments makes much sense. The printed pieces are probably heavier and less stiff as a result of being small segments. I would recommend that you create a parametric CAD version that generates some unit length printed truss (if you haven't already). I also think that using advanced vase-mode techniques can get you maximum strength to weight ratio. I recently released some advanced vase-mode cylinders on printables for model rocketry that have built-in strengthening ribs as part of the CAD model and are printed purely in vase-mode. I can't post the link here unfortunately but the model name is "Advanced Vase-Mode Hollow Cylinders (model rocketry related)" if you search it should come up.

[@ledocteur7701]

I think even if it doesn't turn out to be any better, it's still a really cool modular building system. what I would personally do is not prioritize weight, and try to focus more on improving modularity and ease of use. modular systems are jack of all trades, unless extremely specific condition, a purpose-built system at equal cost will always perform better. if you want to make it lighter you might want to look into topology optimization for your 3D printed segments.

[@MichaelMacGyver]

Really cool idea, the customizable frame design seems like it'd be really useful for things like enclosures, hope you keep iterating to see where you can go with it. Another idea would be instead of trying to start from scratch and designing your own linear rail system, maybe you could look at an existing linear rail and see what the bare minimum that you could add to it to turn it into a gantry, combining the best of both worlds (a proven effective rail design and a cheap yet lightweight extrusion to attach it to).

Please continue this! I'd absolutely love to learn from what u end up doing so that I could maybe make a whole printer that's light and easy to bring around someday!

[@nathanb62]

[@coderentity2079]

Do it. Speed of one isn't important. Just do one, print the next one with it, boom double speed. Have two nozzles on the same gantry, have two gantries with two nozzles, check their combined speed. Have 1+2. Use 0.6 for filling, 0.2 for outer shell plus a 0.2 water soluable. Lower the number of corner kinds by using a square. Make the interconnecting plastic parts lighter (no extra holes) and longer (less work to assemble). Have a version of interconnecting parts that don't expose the rods - only the gantry needs that, and would make the rest stiffer. Awesome project!

As you say at the end, maybe scaling it up would do the job As it guest bigger it gets lighter in comparison with the linear rails since they are entirely made out of stainless, where getting bigger means more still while this in the other hand have all that empty spaces

[@timfalken3886]

Have you ever seen the Positron? It's also got some clever ideas to print even faster--the most important, I think, is printing upside down to keep the print head as low as possible, reducing the wobble of the frame. The bed is then upside-down, which seems to work just fine. Maybe some of the concepts used there could serve as inspiration for your project? Combine an ultra-light frame with a low center of mass, and a low printhead that can dash back and forth without shaking the frame apart.

Finding that a solution doesn't work, back to design for it , or perhaps finding a lightweight metal solution to replace it with, etc.

Smooth titanium rods are definitely the way to go. As far as filament goes, here are some things to things to think of. For Stiffness, from most stiff to least, there is (Carbon Fiber Filament, HIPS, PLA, Poly Carbonate and then everything else). For Density from lowest to highest ( Polypropylene 0.9 g/cm3, HIPS 1.03 g/cm3, ABS 1.04 g/cm3, Nylon 1.06- 1.14 g/cm3, ASA 1.07 g/cm3) and then everything else). For Strength from strongest to weakest (PVA, Polycarbonate. Nylon, PLA, ASA, PETG and then everything else). For Durability from most durable to least, (Nylon, Polycarb, ASA, Polypropylene, ABS, PETG, HIPS, PVA For a part that needs to be stiff and light but not necessarily durable (Carbon Fiber Filament) For a part that needs to be light and durable but not necessarily stiff (ASA or Nylon) For a part that needs to be stiff and durable and light (HIPS) You can find more material info on Simplify3d's resources page.

[@knucklehead83]

Did you ever do a comparison of the assembled portals? It seems that the truss would have a more uniform stiffness. The base gantry is going to be stronger in the wide plane than the narrow plane by a large margin. I would like to see some strength tests done on your trusses. I considered something similar for building a 4' x 8' CNC router gantry. Only using MDF instead of printed plastic. I think you should(maybe you already have) keep going on this idea. Even if you don't make something revolutionary, you might come up with something that could make building homebrew 3D printers more accessible.

[@luke_fabis]

Look into Arris Composites. They specialize in conformal, compression molded carbon fiber composites. The performance of parts manufactured with their technology is honestly ridiculous; light, stiff, and resilient as hell. And since they're mostly carbon fiber, they're also electrically conductive, so parts can behave as their own strain sensors. I've never seen anything like it. The only drawback is tooling. But it could be a game changer for high performance FDM printers.

[@donrozwick7367]

Please continue investigating this design. It is really cool.

[@michaelschaub]

I love the idea. I was considering something similar once. However, it is not a reasonable way forward: Tests with 3D Printed parts show, that the stiffness of any printed material is not sufficient. When you upscale it or you try to go for higher speeds, it will introduce wobble. Now you add some stiffness with your metal rods, but this again adds weight. Way easier: Buy a 2cm x 2cm carbon fiber pipe and mount a linear rail to it. The endproduct is lighter. The stiffness is increadible - even if you upscale to a large format printer. These pipes are standard parts, meaning they are affordable. What you get is greater stiffness, less weight, less effort and a concept that works for every printer size.
