if it ever breaks, then you know where a weakness is and can redesign a replacement piece thats stronger. thats whats so good about 3d printing.

[@miranda.cooper]

Yeah I'm going through this with a thing I made to hold my flight sticks to my chair. I keep kicking them accidentally because my room is too small... and I'm most definitely finding their weak spots xD

[@onewa712]

Ohhhhh yeah 🙌🏽👌🏽

[@noonez190]

love your channel ! finally someone talking metric!

[@clypeum5063]

Everybody is talking metric lol hes Not living in the US but in Europe. So yeah...

[@vincentguttmann2231]

@Barbara Stamm Some americans would like to disagree, but you get what you're meaning. A decimal measurement system is super useful.

[@dineshvyas]

Metric and no loud music, so much fun to watch.

[@sedatminer4489]

:D

[@JJShankles]

Now I wish I could buy things in metric in the US so I could follow along without all the conversions.

[@flymypg]

About Alexandre's concerns about long-term strength and stability: 3D printed parts tend to work better in compression than tension. Which parts of the chair are under the most tension? That would be the parts from the inner star down to the middle of the legs. Does the design minimize the tension and maximize the part strength? No. Minimum tension on the 3D printed part would be normal to the leg (minimum torsion/torque), meaning the bottom star would need to go below the leg attachment points, not above. Which would hurt the design aesthetic. Another approach would be to share the tension across more 3D printed parts, such as by adding horizontal dowels uniting the middle of the lower legs. A box structure connecting the legs could provide this, with the parts to the lower half of the inner star being kept for extra strength. To retain as much of the design aesthetic as possible, I'd design the side supports to look like the supports under the seat for the back, with rounded ends exposed to the front (and optionally to the rear). The front and rear supports may also need to be exposed, as putting them in pockets may make assembly impossible. One beneficial effect of this approach is that it may make the chair stackable. But would anyone want the resulting chair? Would it be too chunky or beefy to retain its current elegance? To maximize the strength of a 3D printed part under tension, we want the tension to be applied along layer lines, not across them. Which can be done by proper part orientation on the print bed. It may be the case that ensuring this for the current design will provide enough strength to meet the need.

[@MrUltramove]

I love how your analysis is detailed, but your are talking about theoretical values which would increase strength. There is a limits of strength in real world, that can be applied to the chair, in general use, sitting, standing on it, things like that.. Your idea of increasing strength by changing design can and will work, but will it be noticable in use? If this design is good enough for sitting of average user, there is no need of increasing its strength past this point.

[@BrennanLetkeman]

@@MrUltramove totally this - of course you can make something stronger but if it's already strong enough, if it's a chair that successfully does chair things, then it already wins. it is sufficiently elegant.

[@dineshvyas]

@@MrUltramove that is not correct. PLA parts fail quickly under tension.

[@GetHandsDirty]

I’ve been watching a bunch of your videos lately and they are so good! You always come up with interesting projects and the filming and editing is awesome too. Keep it up!

[@achappel]

Hey thanks for the kind words Cristiana:) I'm pretty sure I've watched all of yours too✌️

[@matyassveceny7573]

can we agree on that hardly anyone would build this on his own(or at least me), but we LOVE to see this man making these things... Incredible creativity !!!

[@rama3njoy]

cool design but dumb idea.

[@BLBlackDragon]

I don't know. My daughter loves when I do 3D printed things for her. I could see making a little reading chair for her room.

[@jukees3658]

i would do this if i had a place to do woodworking

[@ImKittyCow]

@@rama3njoy dumb idea? who pissed in your cereal

[@novicemak]

I don’t usually comment on KZbin videos but I just wanted to throw this out there and express my sincere appreciation for your work, Alexandre. After only watching a couple of your videos last night, and subscribing since it was a no-brainer for me, you helped me pull the trigger on purchasing my very own 3D printer and entering a world of exploration, learning, and curiosity. I’d wanted to buy one for years, but somehow I never understood it’s full potential, and more importantly, I never realized my own potential. You enlightened me to both. Keep being yourself, Alexandre, from one creator to another ❤️

[@grahamserle7930]

I understand exactly where you're coming from. I'm a woodworker/creative guy who bought a 3D printer in July. It takes time to get your head around 3D printing and there will be some failures along the way but it's an amazing tool for making all sorts of bespoke parts etc that are gratifying beyond words. Just do lots of research before choosing your printer. Good luck.

[@luisfernando55]

Novice Mal, which one did you buy ? Thanks

[@novicemak]

@@luisfernando55 Prusa i3 MK3S kit :)

[@luisfernando55]

@@novicemak congratulations, what's the first thing that you are gonna print ?

[@novicemak]

@@luisfernando55 Thank you so much!! Technically, the first thing I printed was the stock Prusa logo while testing the print quality and a Benchy. But the first print that I created myself is a tiny tiny lug to fix my dad's old Casio watch which is still a work in progress! Working on more projects atm

[@jonathan-gb4ok]

I would love to see a 3D printed shelf combined with wood. Great video!

[@jncodegen]

I would love to see *how* you design something like this and talk through your thinking process! Something like your storage-chair video, but with commentary on the problems you are solving, how you think through them, and how you are solving them. EEVBlog does this with PCB analysis and I learned a whole lot from that channel!

[@LogHouseFarm]

It's like a spiderweb of broomsticks - I love it!

[@Bluefleur_]

Can you make a video about your process of 3d modeling and what softwares are you using, please? I like how you 3d design and the detailed plans that you make and I want to see how you make them and the thought process that goes into them. I'm new to 3d modeling and printing and your way of doing it is what I strive to do in the future. Thank you for sharing your creativity with us you inspire me a lot.

[@markgagnon28]

That would be a cool video to see how much weight the chair can hold in PLA vs in PETG.

[@Enginehearth]

Very nice! I would like to see a CAD designing timelapse too :)

[@lucacianchette9570]

I love how happy he is in all of his videos!

[@JanosKehl]

watching this while my printer is working on additional inserts for my DIY living room wall. There were speakers, which I don't need anymore. now I print little inserts where I can connect some plywood as a small shelf. Your Videos give me some creative ideas to just try and build things. Thank you so much! Keep it up!

[@ryanvargo4907]

There’s nothing more satisfying than a clean removal of support structures

[@dr.sawdust4278]

I love the design!

[@MFM_Gaming]

I love to see updates of this and like I don't know like actual weight testing and stuff.

[@paolo_mirko]

[@jerrylittle7797]

Fun! I enjoy your designs and the enthusiasm you have building them. Your video production is excellent!

[@jonathanhernandez90]

Tip : if you rotate your part in the slicer on the xy plane you can get the support to come out like an accordion. Which is much easier to peal away

[@paulolange3462]

This is something i'm up to. I'll design some forniture, print some joints, see how will hold over time and work for it. Love your channel!!! It's such an inspiration

Nice work... Thanks for the video.

[@abdullahfehmi]

Alexandre keep up good work, you really produce very insightful and high quality content!

[@flymypg]

While I also plan my prints to minimize supports, Alexandre's use of wedges is insanely ingenious. Gonna steal this and run with it! Edit: Just realized you don't need to design the wedge as a separate part! Slicers will let you push the part into the bed, and print what remains above. So the process is this: 1. Put the part on the bed. 2. Orient it for minimum supports. 3. Push it down into the bed to get a good base. 4. Copy/duplicate the part. 5. Mirror the copy vertically to create the wedge. At least I *_think_* that's the way to do it. May need a 180 degree horizontal axis rotation instead of a vertical mirror operation. Will need to give it a try to know for sure. But the general idea is sound.

[@nrdesign1991]

It's much easier than that. Design the part as needed, then use the slicer to cut them in half at a specific height. The slicer can then flip over the part you want as the wedge.

[@JelleVictoor]

this is incredible, nice job!

[@james_snook]

I downloaded your files, printed all the parts and after some labor I finished my chair today! I´m so stoked on your design! The chair flexes a little but after one day of use it's still intact. Cheers!

[@ImpatientTurtle]

Can I ask how much pla you used in total? Hows the chair going after a year? Im thinking of making this haha.

[@jcb0trashmail]

@@ImpatientTurtle It's still in one piece after a year but honestly I'm keeping it as a decorative thing not really as as its intended use. All in all it took me about 1,2 kg of PLA due to some misprints. Next time I would rather choose PETG which I think would work way better in this application.

[@ajmckay2]

Another great video! To be honest most of your printed parts are a bit advanced for me right now (and big!) but I think your use cases for 3D printing are very good. You really have some great ideas on how to incorporate traditional with modern manufacturing techniques.

[@BenKDesigns]

I just started 3D printing, but recently discovered the "tree" supports in Cura, and I love them so much. You can set it to use the print bed only, so there's literally only the point where it's supporting your model to remove them, and generally no pliers or cutting required. Just pop them off everywhere. ;)

[@Knatte_Anka]

One tip use support enforcer block only on each side of the holes in the slicer then you get less support and comparable print because i can do bridges on the rest

[@mrpropermrproper]

I really like your videos

[@xremming]

Yet another amazing design, hats off to you, this really seems like something one might find in IKEA.
