PLA vs PLA+ vs PETG: Testing Eryone filaments from mechanical strength aspect

In this video I am testing Eryone filaments from mechanical strength aspect. PLA vs PLA+ vs PETG, which is best for 3D printing different mechanical parts. This is a comparison test, but I will try to keep these tests as some kind of standard, so they are comparable with each other.

Dr. Gaspar, I truly appreciate your testing approach, you’ve saved me so much time and filament. I’ve recently had a lot of fun printing and testing roller bearings, some have even been used in functional parts. I’d love to see your evaluation of the popular designs, and how material selection affects performance. Thanks for your work!

Thanks. Those roller bearings, where did you used it? I will use them in rotating spool holder, video in few weeks... works great.

Nice testing, and I really appreciate the effort, but it's not a full picture and I still think PETG is not given enough credit. While PLA is OK for some decorative prints I think PETG should be the first material of choice for some functional prints because of it's great layer adhesion (one of the main weaknesses of FDM printing). Being water and UV resistant the PETG is also a great material for outdoor use.

This is where i'm struggling with the results of this video. I'm not saying anything is incorrect, just not sure what to think. While I did not do any real tests, my pla+ prints seem to be much stronger than PLA. To the point where I don't want to use regular PLA for much.

@@rickybobbyracing9106 PLA+ Performance can vary from brand to brand, there is no set recipe or definition what what makes PLA+ as such, your mileage may vary. My personal fav. is the eSUN PLA+ filament particularly because of the higher elasticity. In the end the best course of action is to decide on filament based on your own needs and tests.

Great video, I am glad I found your channel. This is really valuable info. There is so much talk about differences in materials that you have to sit down and really test the assumptions. You are showing there is no magic. I wonder about the consistency of material from spool to spool. I learned early that dimensional stability over time for PLA was fairly low. Pieces I printed a year ago will have loosened up due to long-term shrinkage. I learned to temper my expectations of engineering tight tolerances. I am just now trying the higher temp materials.

I was thinking of trying PETG but I can say from this testing that it would not benefit fit me. I Can say after many years from moving away from PLA to PLA + I can clearly say PLA + is my favourite for making functional parts for proto typing before 3d printing in metal. Also I can say Parts are made very accurate and can be printed with less supports and doing it so reduces the clean up

I really liked your double shear test. You might consider a cross screw to set and hold the gap for each test. I suspect that some of your deviation was caused by the varying gap in the plates as the test started. A simple upgrade to the twisting test might be to use a t handle instead of a ratchet to avoid bending movements. You could also add a bubble level to the t handle to monitor your motion. Nice work, it looks like you are having fun with this.

@MyTechFun 3 жыл бұрын

I agree to adding cross screw (only I need longer plates, these are too short, soon..) I also agree with twist test suggestion, but I belive that the difference will not be significant.

PETG can absorb water vastly easier than PLA. Thus you will have issues with PETG long before PLA due to being loaded with water. Dry the PETG and see the difference.

I don't trust my textured sheet for prints longer than 1-2 hours because a corner or area will always detach and effect the print. Thanks!

In most cases, textured is for PETG and smooth for PLA. Sometimes I am lazy, and left textured for PLA. In that case, clean with IPA when it is cold. And pay attention to live-Z, if it doesn't stick good, you may need to lower it.

Hi Igor. I would really like to see you test and compare different brands of PETG for their heat resistance and for their strength, etc. And it would be awesome if you could include Geeetech PETG, because that's the one that I always use since I started using PETG. The thing is, I don't really know if the Geeetech brand one is really the best suited for my applications, and I can't find good information, especially about the cheaper brands, like Esun, Eryone, Geeetech, etc., so a comparison of these would be great to have.

Do you think the PLA was annealing while it was softening? It would make sense that PLA+ would have things to inhibit crystalline growth (crystals are usually a little more brittle). It would explain why it started to deflect and then slowed down.

@eddiemauro.design 4 ай бұрын

Esun has so many good materials, but what I'm sure is that PETG is mostly harder (elongation) material than PLA+ (better with higher temperatures and higher UV levels)(but anyway leaving the elongation, PLA+ is overall fine). Your video is super, probably comparing it with other brands, could be better (PLA+ is different than Esun, and probably, Eryone has a not so good PETG). Greets!

@@MyTechFun it's relatively new, within the past year. It's from Sandoz. I ordered a couple spools by accident but have been playing with it a bit. It's supposedly solves the warping issues with ABS and is easier to print, while being stronger and higher heat resistance than PLA. I'll admit I'm new to 3d printing so I wouldn't know how to compare it as I pretty much started with PLA-F instead of PLA. Aside from some weird stringing, it seems to be as advertised. Stringing could just be my own inexperience too

Using pla, if any of those chairs fall to the ground, at least 1 leg will break right away. The PLA+ chairs, I can throw on the ground Andy Samberg style and they are fine.
