- I tested the effect of infill pattern, infill density and shell thickness on the strength of 3D printed parts! There is too much superficial knowledge around, so I approached it a little more scientific.

I love the scientific approach to testing! Definitely one of my favorite things about your videos.
Would you mind to share your figures/graphs? I feel a bit lazy.
It's the filament sellers that dislike 😂
You are the man! I love your videos because you face the 3d print as a science, not like others that only print stupid things without any sense or objetive, good job Stefan! keep doing that amazing job!

Final Conclusion is INCREASE SHELLS AND DECREASE INFILL. How the hell unlike this video? This is awesome.
This is not universally true. Very dependent on loading case.
What are shells, please?
over time you also have to account for cats jumping up on the keyboard and clicking dislike on a video, 1 out of 100.
The ones who would dislike the video are working for big-infill. That industry has a lot to lose because of this video. They want to silence the truth! Also, as stated above, cats.

Being a mechanical engineer by profession I can say that this is what moves 3d printing forward. Thanks!
I need to make high strength, light weight parts and this video definetly got me thinking about my design. Especially the possibility to make dual walls at high stress points to add strength while keeping the weight down. More of this please :-)
I know this might struck your ego and sense of self entitlement, but "being a mechanical engineer by profession"(whatever that's supposed to mean) doesn't give you any extra capability to evaluate what moves 3d printing forward. Any 3D printing hobbyist can do exactly the same, but you had to come to the comments writing something to make yourself feel special, I understand, some people are insecure like that 🙃
@AlexandreG And you seem to enjoy interpreting comments ungenerously. Most money spent on 3D printing is by industry, not hobbyists. Mechanical engineers play a significant role in choosing printers and designing parts. Suggesting the perspective of a mechanical engineer is no different than the perspective of a hobbyist is silly. Both perspectives have their value. While you may not like @Meglification 's tone, devaluing their perspective to justify calling them insecure is excessive. And an unreasonable reach.
@@ericmanternach2340 As you might have noticed, I didn't say I'm a mechanical engineer to give value to what I said but apparently the guy is right, some people will just take your word for what it is if you take crtedentials, thanks for showing me. A year ago, me as a mechanical engineer boughta a 3D printer and it was my hobbyist friends who introduced me to it in many ways I didn't even think about, they knew much better than me. And surely they know just as much as me what might move 3D printing forward. Me being a mechanical engineer doesn't make me more entitled to what moves 3D printing forward compared to a person without a degree. Hope you were clarified
8:24 15% Full Honeycomb, 2 perimeters is stronger than 75% and 30% infills (same pattern, same perimeters) wow, that's impressive. I'm already using from 5% up to 20% only for really sturdy prints. Great video!
Wonderful analysis! It is refreshing to see a TH-cam video with solid engineering/scientific methods and result presentations. Well done.
I love the rigor with which you do the testing. Varying only one parameter at a time. And thoroughly analyzing the results.
Great job !
You have one of the best hardcore engineering of 3D printing. Keep it up!!!
At this point I’m thinking Stefan has more hooks than Ikea’s curtains and upholstery section.
Thank you for the great test results, this is well worth the watch because as a new user this type of testing would have taken weeks, but now I'm convinced that I have a new approach to printing.
First time watcher and subbed right away. I love how you get right to the point and appreciate all the work you do in your tests. I just got into 3d printing and was messing around with shells a few days ago on a very small part but it had to be strong so i set shells to 1000, just to insure a solid part. To my surprise it worked great but took a long time. So this video taught me new things.
Man I love your videos you really go in depth at what your explaining, Keep up the good work!!
That was a very nice test, your video are always of a great quality from an engineering point!
Proper tests with proper usable results. Thanks!
Fascinating, I’ve just started 3d printing and have only fiddled with the settings a little, this gives me an area to work on, many thanks.
Great analysis Stefan! I really appreciate your rational scientific approach in a world where too often speculation is king. Keep up the good work!
Great video! Thank you for taking the time to do and share this experiments! The results are in some cases quite unexpected. Thank you again!
I just found this and it's very good. Thank you for your scientific approach, it really determines what works very quickly without opinion or conjecture.
Your systematic approach is really refreshing. Nice work!
Thankyou and what a surprising result. I'll be using this information in my next functional prints. I like that you explained the result and why.
Just found your channel, thanks to a shout-out from Angus. Really like your detailed test and measurement approach.
On this particular topic, I'd be interested to see how the cubic etc infill patterns in Cura perform - they claim to achieve more consistent strength as they move layer to layer by building a three-dimensional internal lattice. I can see they should be stronger under compression in all directions overall, but I imagine the layer adhesion for the infill itself is significantly weaker when under tension.
I think you make great videos, thanks for that! I almost only print stuff that I use on my car, drone or in my home. So strength is number one prio for me. This video helps alot. I did allways print with 2 perimeters and 100% infill before. Now I use more shells instead and lower infill :)
Excellent video once again! I appreciate your scientific approach and your willingness to share results.
Excellent and clearly time consuming tests. Your work is appreciated! Thank you!
Thank you for sharing this knowledge. Your videos are helping me to learn as I enter the world of 3D printing as an old school sculptor.
Awesome work Stefan. You hit this one out of the ball park. Best Yt channel out there.
That was very useful information, thank you for saving me time on doing this on my own
Best video on the topic. Super easy to understand.
I’m going to look to see if you made a video with the updated infills mentioned at the end of the video.
Very great work. I didn't know your channel. This video was the perfect answer to my question about infill.
Thanks a lot
Thanks for the analytical approach!
thank you a lot, this is what i am looking for,
i hope you can do more video about the filament's use and testing the object not just in traction but also in torsion and fatigue
Great quality of video and information. Straight to the point amd very well explained. Subbed 👌
Great video. Love your content!
I would add a comment/reminder regarding part orientation as the biggest factor (before even looking at infills, perimeter layers etc... whenever possible). It might be obvious, but understanding the load path of your designs and orienting the part on the print bed so that the load paths are in the XY plane (continuous filament) is likely the most efficient way to get strength for a given weight. I know it's not 100% the point of the video but it's still a good reminder. You have shown us how anisotropic printed parts are.
Learning a lot from your studies.
agree, and I've found that layer cooling is huge too, particularly when I am printing multiple parts together like these hooks were, and the slicer is making decisions on travel with parts that are being build up side-by-side.
Great engineering approach while still being practical....keep 'em coming!
Very insightful video! Thanks for putting in the time effort and material into this thorough investigation. A look into the cura settings would be very interesting to see as well.
Got into 3d printing not too long ago. Your channel has helped me a lot! Thank you. Subscribed! :)
This is an awesome video that's exactly what I needed to know!
thank you for taking the time to do this much needed research
More please! The infill orientation relative to the load vectors will also make a difference but that is a more advanced topic.
Just sub'd. I couldn't click fast enough when I saw the title to this video. Iv'e been hoping someone would do this very same test for a long time as I print almost exclusively end use mechanical or mounting parts. Very thorough, answered all my questions.
dein Kontent ist echt Top. Ich bin mehr oder weniger gezwungen 3d Druck zu betreiben und Deine Videos befriedigen meine Neugier sehr. Danke für die viele Arbeit.
Nice work! And very informative. I would live to see the same structured approach regarding the wrapping and the surface quality .Thank you
Dude, I am new to this hobby. Thank you. I needed to find this I’m glad I did. The settings in CURA offer so many options and variables. So much to learn. So little time.
This appears excellent! Cannot simply wait to see the same as this. Great job.
Another awesome video from you. I really like the content and the quality of your work. I will try to help you keep growing. You deserve many subscribers. Cheers Roy
This guy is awesome, I agree!!!
Thanks for sharing Stefan, I love the video. I think a good follow-up video to this would be to see how the same approach to perimeters and infill works when printing in a Z axis.
Thanks stefan ..old video but really useful to learn something from this channel. Alot better than others! :)
Wow that was impressive!!! If possible, how about you test the strength of the specimen when using different nozzle diameters?
Excellent work Stefan! You have a new subscriber 😀👍
This is really great and useful video! Want to see much more such content. Layer adhesion (printing other orientation) and comparing different filaments would be great.
Very informative video. Your analysis is very helpful. Thank you for sharing.
As has been said your videos are the best when it comes to actually seeing how strong a part or material actually is. I would definitely like to see a test of the 3d infill pattern as that is what I use when I want a part stronger in multiple directions, but I'm not sure how effective that actually is.
Fantastic video! Not just speculation, tons of real data collection and actual science! Very thurough! Subscribed!
Awesome video! This is something beneficial considering I am starting to print parts that need to be strong.
Thanks so much for this research, Stefan. I'm designing a 3d printed C-clamp, and the first iteration would break quite easily if tightened even slightly too far - I increased the number of perimeters from 2 to 4 for version 2, and when I attempted to test it to destruction, it actually crushed a small indentation into the underside of a particleboard table before I chickened out.
It took some time, but I got there in the end. Now, I understand exactly what is meant by this video. Not because of its production. It is extremely well made and explained. It is that up until now I did not NEED to understand it. I have been firefighting one problem after another with the belief that if it ain't broke don't fix it. That of course was down to confidence in what I was printing. Now I can experiment knowing if anything goes wrong I can fix it. CNC kitchen has played a big part in building my confidence and I will always be grateful. Thank you, Sir
Awesome video! Just the right amount of info to deal with real pragmatic situations.
Nice job testing this out. I've found that if you want strongest part, you have to determine outside forces nature and enviroment first, then select corresponding material (PLA is fragile, so you wont go with it for impact-proof things, for example), then orient your part so that force goes parallel to the shells in most critical part, and then select infill and shells amount.
Thank you for this very useful video. I'm just getting into 3D printing and videos like this are very useful to help me learn :D
Super informative and presented perfectly. Thank you so much. :D
Just what I was looking for, thanks so much
Using all of your tests, you should combine your findings and print a set of test hooks. I would love to see how strong a hook you could make
all roads lead to a solid hook lol
Thanks - this was an excellent analysis! I would suggest trying "Stars" in Slic3r. It's my current favourite infill as it's strong in many directions, and also prints quickly as there are no direction changes mid-pattern - the direction changes only occur at the perimeter.
most useful video I have ever found in 3d printing.=)
Thank you very much for this video, it helped me a lot
thanks for doing the science! Great job. Very informative.
This is very useful. I'm in the process of making a helmet for a costume so finding out the strength of each pattern was useful. Also, this could be very useful when printing out props as well.
Awesome. Finally there is a great video on this topic I can share to all those infill fanatics.
Big thanks
very useful!!! thanks so much. Love the scientific approach. your explanation is good and easy to understand. Not to technical. thanks
Great, informative video.
Thank you
Damian
super clean prints! thanks for doing this!
This was incredibly useful. Thank you !
Thank you very much for the data! Great video!
This is wonderful material testing and very well done. Infill and shell (but not perimeters-- how interesting!) were settings I was thinking maybe would help improve my prints but I didn't want to go through each combo myself ;)
Really good video, intelligence and creativity a great mix!
I'm new to 3D printing. Great video and methodology. I subscribed to your channel.
You are wise to choose a good model to test both compression and tension stress at the same time. In fact in one of the slow motion video, the crack happened on the compression side first rather than on the tension side as many people would expect. If you could test torsion stress as well then it would be a more perfect experiment. Thank you for your contribution to the 3d printing community. There had to be a lot of effort you gave.
Super Video! Du hast dir wirklich sehr viel Mühe gemacht und dein Englisch klingt auch sehr gut! Daumen hoch & weiter so!
I always have to think about bird bones in this context, mostly hollow with "struts" on the inside. Maybe we need bird bone infill.
Google for lattice optimization. e.g. Autodesk is working on these things, but they are not optimally usable in FDM at the moment.
If you do a topology optimization simulation you will get a result similar to the bird bones structure
Concentric seems to do this depending on your density
By intuition I was already doing that not to put too much filler but to put more outer layers. now I confirm that I was doing well.
Thank you very much for uploading this video
Your videos are the best! I'd like to point out that in Cura 100% infill will actually make as many perimeters as needed to fill the surface, instead of using paralell lines like S3D, so you would get Pisces a lot stronger with 100% infill in Cura.
Amazing video! So in depth, felt very complete, you’ll blow up on YT I’d bet
Fantastic video. Always wondering about the effect each print setting has on time/strength, and now I don't need to do my own experiments!
Very neat. I'd love to see follow up with Cura's cubic etc. 3D infills. My current approach is to print cubic infill at about 33% and 2 perimeters as the default strong part, and using the gradual infill function to bump up the infill to 65% for the last few layers to get a good roof support.
This video confirms my own research on the perimeter shells. I sliced in S3D and print 3D boat parts for some low load rigging parts and some other areas. They work fine when the part is correctly drawn, load vectors are aligned, rounded edges (sharp edges brake sooner), 20-50% infill (usually triangular), Number of shells (5 is good for this application), material and color (black seems to be the most U/V weather resistant in any one material). Good work.
Awesome video! Extremely informative
Wow, great Video... lot of work done here.
Nice, your approach to the problem does a very nice job of quantitating this and also explaining why it should be the case. I came to similar conclusions that the rigidity of a part is mostly coming from the wall thickness, as long as there is *some* infill to brace the walls. Even parts that have to withstand significant crushing force don't need a lot of infill. I am usually using between 1.2mm walls and 10% infill, to 2mm walls and 25% infill. That's between 3 and 5 outer walls (with a 0.4 mm nozzle), and an infill grid size of between ~7mm and ~3mm. I prefer the grid type infill based on speed. I also use the "connect infill lines" option in Cura. This reduces visibility of the infill lines on outer surfaces, and also helps adhere it to the inner walls, while giving them even more thickness/strength.
Excellent and informative. Thank you.
amazing job!!! well done!!! I loved what u did :-)
Excelent! Few technical videos like this one congratulations!,,
I really loved this test ! Did you consider making an updated one with the infill available in Slic3r PE, like gyroid ?
Great info man! Thanks!
Awesome info brother! I see so many people cranking the infill up to make stronger parts when they should just increase the wall thickness a tiny bit
Beautiful analysis, well done sir :)
Finally! you answered my question, I wondered why my parts were weak even when I printed at 100% infill or with higher outer wall and why my prints failed when the infill and outer wall were too high. For a while I've been printing with 15% to 20% infill and with an outer shell/wall thickness =
Brilliant video, great work.
great technical info. Much appreciated.
You could probably publish a research paper with this information! Great work. Thank you!
Great work with very useful information!
