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!
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.
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.
I'm really enjoying your channel for the last couple of days, thanks for another great video, it exactly answered the question that I had about PLA+ vs PETG. Thank you 👍
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 think this video is very good and you have done a fair test with some nice equipment to give an accurate result So thank you for putting a lot of hard work to show us the advantages and dis advantages from these filaments. 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
The biggest advantage of PETG is chemical resistance. In most industrial environments there are always chemicals such as harsh cleaning chemicals, solvents in lubrication etc where PETG shines compared to PLA+. That’s my experience using it in industrial environment.
These real life material tests are awesome. I was hoping your website had a page dedicated to the Excel/GoogleDocs/PDF data for all the tests results side by side for all the filaments you have done.
So far I don't, but you can collect them from mytechfun.com site, in most cases, there is a downloadable file on bottom of each video page: www.mytechfun.com/videos/strength_test
Loving the testing methodology used here and the results reporting. From looking at the view looks like your up a few floors. When those pieces go flying from the test, I wonder if the people below or on the street wonder where is this plastic rain coming from? lol
Every video has it's own page on mytechfun.com website. In near future, I will add results to those pages too, so you don't have to watch the video to find and compare them.
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.
Eryone filaments my go to ! outstanding INTEL . The torque test should be done in a single sweep with our reposition as the molecular structure of material will change if rebound giving inconclusive test results ) Thanks
Nice Video. I used for age PETG but I replaced it with PLA+. Sometimes PETG deforms under loads, sometimes it is brittle and I do not know why (same roller same parameters). I am more confident with PLA+. Moreover it is easier to machin PLA+
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 stopped using PLA for usable prints because of PLA creep ... that means it can bend and deform under constant load. PLA is fine if you just make prototypes and fitment test before you print the part in PETG.
@@pizzablender In my country by local seller, PETG is a tad bit more expensive than PLA or almost same price. For you or wherever you are buying is cheaper ... but not for me xD
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.
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.
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. Thank you for your content👍
Good video! Like PLA because is eco friend. No smell. No warp. The process temperature is slower. I use petg only in external pieces. Ow... I like nylon too. I have open ender 3.
Every video has it's own page on mytechfun.com website. In near future, I will add results to those pages too, so you don't have to watch the video to find and compare them. That will be useful to me too.
Thank you for this video,where is the cheapest place to buy esun pla+,ebay has them for $22 and free shipping and Amazon is give or take same price but when shipping is added it's almost $30
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!
All filament type are sensitive to moisture. With that said, the regular pla that you have unpacked and exposed to the humidity in the air will negatively affect the test results.
Thank you for all the effort you put into your videos. I use Eryone PLA+ quite often. Not related to this video, but what do you do to keep your prints stuck to the Prusa Textured Sheet? 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.
Great video! Have you had any experience with PLA-F? The PLA/ABS hybrid filiment. I have seen a few videos comparing these 3, but no comparisons with PLA-F! Would love to see PLA-F included in this type of comparison!
@@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
@@davidmuller1958 i print mostly with petg now lol. Keeping it dry isnt too difficult right now because of winter and i have a portable oil heater. For minis i would wgo with pla or pla+. You cannot print with petg on glass unless you use glue stick. You need a bit metal heatbreak or all metal hotend to print petg. Any printer can print pla out of the box just not the other filaments without killing birds
@surchaufeur4601 gotcha thanks. I was leaning towards pla plus since i just bought 3 spools a few days ago for my 3 printers. I was testing my calibration with a leftover petg spool and it went pretty well so i guess ill just stick to pla plus. Im just worried a little.about fumes. Tryna build an enclosure with exhaust to the outdoors. At least it aint abs lol
Пережарил Pet-G, это было видно, когда ключом с манометром ему башку сворачивал, он раскололся, как стеклянный. Температуру нужно до градуса выводить, а не 5 туда, 5 обратно.. Для PLA температура не так критична, а вот Pet-G очень капризный в этом плане. Неправильный обдув также мог навредить. Ну а так Молодец, видно, что старается человек и ему это нравится.
This is weird - and I could be miss-understanding the results. In my 100% not scientific experience, when printing the 'chair game' for example. 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.
Dr. Gaspar, I truly appreciate your testing approach, you’ve saved me so much time and filament.

Thanks. Those roller bearings, where did you used it? I will use them in rotating spool holder, video in few weeks... works great.
Overall, I think PLA+ is my favorite material to print with since it prints so clean and has so much strength in many areas. What a great material.
Have you tried PLA meta?
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.

Are there many situations where a fragile(ish) 3d printed part would be used long term in an industrial environment?
@@zybch doesn't even have to be long term. The prototypes often need to withstand various chemicals.
ive been using eryone pla+ for a few months now it works great.
Thank you for making this video. Fantastic testing methodology and review.

They have already complained about the noise from chain hoist (neighbors below me), but never about plastic rain :-)
Thanks for the testing and time!
It would be good see the testing result compare to the other filaments you've tested before!

You are supposed to break the pins inside the temperature towers to se how "strong" each temperature is

I like to mention the same (PLA bend and deform under constant load). That's the most importent disadventage of PLA in my mind.
I'd love to see you test their dual color PLA for strength/impact

PLA is one of the strongest materials BUT only at room temperature. Just a little above it creeps
@@MyTechFun ahh makes sense. Thanks!
I liked test PLA vs Petg but price diferent here.

Where is the best to high temperature filament ???
