[@Austin1990]

Awesome video, as always. I have some analysis that people may find helpful. Toughness is the area under the stress-strain curve at 7:12. Based upon this, the significantly higher impact energy of PLA+ at 9:48 is expected. However, for most practical applications, the part is considered to have failed once it permanently deforms. This is where resilience comes in. Resilience is the area under the linear portion of the stress-strain curve. Looking at the graph unmodified PLA is significantly more resilient. Moreover, it has a larger strain before permanently deforming. This makes the unmodified PLA significantly better for the vast majority of parts. From these numbers, an easy rule of thumb is to not even consider PLA+ unless the part you are making is intended to be permanently deformed, like a bumper that needs to absorb impact energy.

[@bengtr7352]

I could not have said this better my self. A part is broken once it have made a permanent deformation. And it will probably be completly broken if you bend it back so it can perform the function it was made for. This is relevant when comparing PLA to other materials also. I always see a trend where everyone want ABS-like materials. But ABS is weak crap, but just because it have impact strenght people think that is all that matters.

The main benefit of PLA+ seems to be less warping and better bed adhesion, two of the things that discourage beginners often. I feel like these companies need to market it as beginner friendly instead of as an upgrade to PLA or a "tough" version. Most people starting out are printing nick-knacks and vases, so tensile strength and impact resistance are much less of a concern over printing properly. As people progress into functional parts they can move into pure PLA, PETG, and ABS depending on their needs.

You should test materials for creep, it's probably the greatest weakness of PLA other than low heat deflection temperature (but that can be fixed with annealing, seems like creep can't). I've had some PLA parts fail with stresses under half of the tensile strength, just over a long period of time.

[@victortitov1740]

+1, have had quite a few crack apart after some months or years of continuous or regular brief loads. The continuous loads were really small. I am abandoning PLA because of this. I also noticed, the older the spool - the worse this problem gets.

[@NinjaForHire]

bro this was very informative, the very first filament I used was PLA+ it just seemed like a good starter option for a beginner and it was a good brand on sale. I was told it performed ever so slightly better but I have been unable to compare it to know the facts thanks for all this information. BTW it was only 21.99 that was 1 dollar more then its cousin of the same brand. I would say the material stress factor was way better all around on the PLA+ because it stretches and I like the more of a matte finish, but in all honesty this preference kind of comes down to what you are printing and its use case. I don't think the one dollar more is too much to ask for a higher print success rate either.

[@iskandartaib]

I first got a 3D printer in 2017, and like everyone else, got a roll of PLA and a roll of ABS. We were warned not to use the PLA for functional parts, but ABS was a major pain in the rear - it warped, it wouldn't stick to the bed, etc. etc. etc. A local company was selling something called "CPLA" which they claimed was tougher than regular PLA, so I got a roll and... well, it was like a totally different material. It was really easy to print, and and it was NOT brittle like PLA. It was tough, like ABS, with none of the warping issues. I was so impressed I used it almost exclusively until, unfortunately, it became unavailable. I was quite disappointed (though I had a half dozen rolls of it on the shelf). Sort of got out of 3D printing until recently (printer needed a new nozzle), and was wondering why no one on KZbin was doing reviews and tests on modified PLAs. Eventually I found a few - mainly involving eSUN's PLA+ - the consensus was that it's tough and easy to print - just as I had experienced. I've just recently got a roll of the eSUN PLA+, and another Chinese modified PLA called PLA-F (which comes really neatly wound on the spool - no more tangles). The former is expensive if bought locally, but is cheap from China, the latter is VERY cheap, as cheap as I've seen for PETG, though not as cheap as some regular PLAs. The company that was selling CPLA is now selling something called PLA-Max, which I'm going to try soon, too. I've got a roll of PETG and will give that a try eventually. I mainly use the CPLA/PLA-F/PLA+ for making accurate tools, patterns, guides and jigs, for which it is totally adequate - this is where I think the power of 3D printing lies, not so much in functional parts (though I also plan to make some of those as well).

I've seen this EXACT behaviour from eSun PLA+. 0.6mm nozzle: No bubbling, at 0.8: Un-usable, it bubbles like it's designed to do it.

[@juststeve5542]

I usually use eSun PLA+, but during lock down I tried some SunLu PLA+ (as I couldn't get eSun), I just could not get on with it. I bought a 3 roll pack of 3 different colours (3D printer stock was getting rare). Each colour sent me back to basic tuning every time, and I never found a setting for any of them I was completely happy with. The silver being the worst. It was like printing with rubber, continual oozing and stringing which left the nozzle empty for the start of the next layer. I couldn't print anything that had long travel moves. Changes in retraction made little to no difference. I don't know what their formula is, but completely parts were noticeably more flexible than I was used to. I might as well have been trying to use PETG! (I have a non-bowden machine for that!). I was so glad when eSun came back in stock. I pulled up my previously saved profile and everything was great again.

[@marcokunz9715]

Had the exact same experience, usually use Esun PLA+, tried SunLu PLA+ - it was the first filament I have used of any kind that absolutely required bed adhesion help. Could not get it "dialed in" to good print settings. The Esun PLA+ "just works". no bed adhesion problems, no warping. Bit of fine stringing that can't be "tuned out", especially on the black, but I just give prints with strings a very quick "flame treatment". I would also like to see how Esun does on the "CNC Kitchen standard tests".

[@69hytek]

I find it funny you mentioned about the difficulties with the silver filament. I have been battling my way through 2/3 of a roll of eSun silver PETG trying to get a decent print. It prints exactly as you say, like rubber. I tried it on both a direct drive printer and a bowden. Just before pulling my printer apart to fix a problem that didn't exist I tried a roll of black then a roll of red. All at the same settings & with the same pre-treatment. Both printed perfectly. Guess I won't be printing silver anymore...

[@arcadeuk]

SunLu used to be really good. Since "Corona" they have massively reduced their quality and I have ended up sending several reels back. It looks like they are extruding it in the cheapest and fastest way possible now, as it used to be a high end filament, and not it a tangled mess of inconsistent width junk

Thanks for doing these tests! I'm a semi-retired mechanical engineer and have been doing my own testing on various PLA+ filaments.

CC3D PLA Max is almost as tough but significantly lower cost; I tend to use that for the majority of my prints. eSun, IMO, is good in that they have a wider selection of colors but is noticably less tough than the CC3D.

I've left eSun PLA+ prints in my car in the Texas summer heat for days and they never warped at all whereas the normal PLA prints I left in there were super warped. You have to print it at a significantly higher temperature which is a good indicator.

[@Waltkat]

Modified PLA is all I've been using for over a year. It's really hard to go back to regular PLA at this point. My favorite is Filacube PLA 2 at around US$24/kilo and second is eSun PLA Pro at about the same price. Stringing has never been an issue. The best thing I like about the modified PLA is that it's not brittle like regular PLA. I can drive screws into it without it cracking and breaking. Any post print work such as sanding and cutting/trimming is much easier too. Almost like ABS. Takes paint well including water based like Acrylics.

Thank you for this. It was one of my Concerns when i switched to PETG full time. This has really enforced my decision. I just wish we had all the Pretty stuff like PLA does.

[@jc-zh9kl]

We need to make a gear tooth strength test and see if the plus is better in that application. Your videos are awesome!

Herzlichen Glückwunsch und Willkommen im Club! 😁

Dankeschön!

Congratulations on the new addition to the family! Don't worry about your schedule, that little one dictates it now :)

[@JohnOCFII]

Congratulations on your baby! I tend to prefer PLA+ over regular PLA for the main reason you show - it is less brittle. I also find PLA+ changes shape less than regular PLA when annealing.

[@darren4392]

I use eSun PLA+ and I'm very happy with it.

[@Zerial48]

I used eSun PLAs, and now using their PLA+s. Along with your differences, PLA+ is stronger against moisture. If PLA absorbs moisture it became brittle, and breaks before extruder, making it impossible to use for print, and printed parts are also way too brittle. PLA+ does not break at the same condition, maybe because it is less brittle.

Congratulations 🎉🎊🎈🍾. Don’t leave the channel please 🙏🏻

[@CNCKitchen]

Thank you - and I won't ;-)

[@Inventorsquare]

Many comments mention the PLA acting brittle. It’s brittle because it is hard, which can be more useful in certain situations. Is there any way you can test wear, penetration, scratch, etc. resistance? That is my use case versus PLA, PLA+, and PETG.

[@4thWardTechnology]

Do an esun pla+ test. This filament is frequently called the best when it comes to printing parts for firearms.

Hope momma and your humanoid analog 3D print are doing well. Just joined your channel. Came here from suggestions by KZbin after watching a Makers Muse video on the Ender 5 which is on its way from Creality as I type. Have an Ender 3 Pro that I'm learning on now. Had a little extra cash from a sale so I'm investing in tools and knowledge.

[@toastinat0r]

If you go to polymakers website, under industrial you should test the PolyMide PA6-CF, it’s strength numbers show higher then anything else I’ve seen including PC.

[@covertpluto]

So you have a child now! Congratulations 🥳

Tbh, I have never used regular PLA. When I bought/build my 1st 3d printer I ordered a spool of PLA plus (made by cctree) which proofed to have absolutely sufficient thermal and mechanical properties for "everyday use". Still use it to this day.

[@AlexDreemurr]

While watching this video I had a bit of a eureka moment as my hobbies and work experience came together to make me have a realization. I used to just watch these videos for fun but now that I'm seriously getting into printing and now know what I'm printing it makes videos like these even more interesting. I'm an ironworker (Steel Beam / Rebar Guys) And right now I'm learning about rigging and cranes, so right now mostly about different fiber and metal wire ropes. For many things Ironworkers use steelwire ropes to pick things up with cranes. they're reliable and can be constructed in different ways to have better bending or wear resistances. (This comes back to 3D printing I promise) Another option that exists out there is using chains instead of steelwire ropes. Chains don't stretch, they're strong as hell, easy to hook shit up with, they're really great. But they're rarely used. Why? Because whereas wire ropes will show signs of weakening before they fail, giving you ample warning to replace them, if chains fail they suddenly and violently snap and drop loads which is dangerous as fuck. So even though chains may be "Stronger," the physical properties of wire rope are better because they give gradually instead of at once, much like PLA (Chains) vs Wire rope (PLA+) This made my search for the right filament click because the objects I will be printing will undergo many shock loads and I'd much rather have my part show signs of failing rather than looking fine until it suddenly explodes when I need it the most.

[@3DJapan]

I bought some PLA+ today for the first time. I haven't used it yet. It was the same price as the PLA.

[@ZeroPointAlpha]

I've printed a few parts with Amazon Basics "Premium PLA", which was surprisingly nice stuff. Printed well, nice and shiny finish, flexible rather than brittle, and it wasn't all that expensive. Sadly they don't seem to sell it any more. :(

[@nerd1000ify]

I got some grey PLA from Aldi (of all places!) that was remarkably good, best filament in my inventory for printing miniatures. Pity they no longer stock it.

[@reeceisaac556]

Congratulations on your new family addition.

[@DarkDekieon]

congrats on the new little maker in the family!

[@Tarex_]

Herzlichen Glückwunsch Stefan! now for the tests of materials suitable for junior haha

[@mrclown7469]

Honest and hopefully constructive feedback: Testing only expensive and hard to source (from a worldwide perspective) filaments greatly reduces the value of the data.

[@3dprintingscience528]

True, however I think Polymaker may be the most widely available brand in the world.

[@nocommentate9017]

@@3dprintingscience528 yeah I would agree, except polymaker is a Chinese based company with one of the heaviest international presences that I know about

[@mrclown7469]

​ @3D Printing Science ​@NoCommentate Point taken. To be honest I've never paid much attention to Polymaker and have always assumed it was a European brand, solely because it tends to be in a higher price bracket than other common filament brands. Learn something every day I guess.

[@KentAsplund]

@@mrclown7469 I always assumed it to be American as it was so overpriced.

[@nocommentate9017]

@@KentAsplund They work with covestro (plastic pellet supplier) to make a pretty diverse additive package to help with printability. That's where some of the cost comes from

[@Hunterstoneking]

I'd like to see a comparison of the eSun line. They're the cheapest and closest in price range to each other, and one that I use. CONGRATULATIONS on your newborn

[@zigmar7]

Looks like a good material for printing FPV drone parts, especially protective bumpers.

[@leoads]

I think that I saw a baby. Congratulations Stefan! You should have done a comparison between esun PLA vs PLA+. Perhaps next time. Great video, like always.

[@maximedesmarais-laporte]

Very nice vidéo :) first time I saw your video and now i am a subscriber ;) Very nice job

[@CapnCoconuts]

Considering that eSun is very inexpensive compared to other PLA+ brands, I'm disappointed it wasn't featured in the video. More people might buy it considering the price point.

[@dannyash3805]

Congratulations!!! You're one of, if not the best 3DP channels out there. I hope you're able to keep it up, but we'll understand if you have to step away a bit.
