INFILL pattern and SHELLS - How to get the maximum STRENGTH out of your 3D prints?

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.

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 :-)

@AlexandreG Жыл бұрын

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 🙃

@ericmanternach2340 Жыл бұрын

@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.

@AlexandreG Жыл бұрын

@@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

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.

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.

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.

@racketman2u 2 жыл бұрын

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.

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.

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.

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.

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.

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 =
