Hi DrVAX, I'm following your channel for about a year now and I like this video. I'm in the polymer business for 26 years now, working on a polymer laboratoy as an application specialist. My job involves figuring out problems with polymer applications for customers. Looking at your video, your test setup is a basic tensile machine. I'm sure you must have a technical background because of the topics you mentioned like anealing, glass transition temp, orientation etc. Of course the speed of which you are pulling to the test specimen must be constant. To be sure: this is not critique. Because of my job, of course I have a 3D printer and using it frequently. Your videos helped me a lot in mastering the 3D printing issues. At our lab we you injection molding machines and presses for preparing test specimen. The main advantidge of inj. molding is the homogenious distribution of the molecules. And also with inj molding, the 'infill' is 100%. Using a hot press there is no movement on a molecular scale and the mechanical properties depend on the intrinsic flow properties of the material. We use PE, PP, ABS, PA (Nylon) and PET. To finish: I really love those videos, keep making them.
So what did we learn, there is no shear strength benefit. That it is an expensive alternative to PetG. Perhaps some comparisons with PetG would be the next test, as I'm not sure if we learned as much as you would have liked from this one.
Quick suggestion ... adding another camera with a telephoto lens for close-ups . Along with a remote . I’m assuming that nylon would be the most durable . If looking for addition strength .
Yes you are correct. I should have reshot. I often use a DJI as a closeup camera. In this case lighting was also an issue because my basement ceiling was to low. While I have defusers on my lights I really need to try putting reflectors on the low ceiling and bouncing the light off the ceiling. When shooting in locations with more space I use umbrellas which produce a beautiful light with less glare.
DrVax, may I request you to make a video on Klipper firmware, advantages and installation? Your way of explaining is unlike others, so thanks in advance.
Nice experimentation. For a distributed load, you could try to set some square stock on top of the test specimen bracket, and lasso over it with your pulling test rig. You may also want more samples to eliminate fluke miss-prints not seen with the eye. Your remark in conclusion about tough PLA deformation in hot car may not be true for a functional part under load.
Awesome video. I inadvertently went through some similar testing buying very expensive, locally made PLA right here in Ohio. I spent $35 for 1kg only to find out it severely under performed in strength compared to the $19 PLA from my local Microcenter , shipped from China. However, their Silk PLA is very very weak, but looks nice. I've come to use PETG for anything that needs strength and PLA for anything that will not be stressed. So interesting how different these can be from one company to the next. Thanks for doing these tests!
Yes I also use a lot of PETG. I am away from my home lab for the next few weeks but when I return I expect to do a number of addition tests using my testing rig. I will compare PETG and PLA and also look at fill factors and number of walls.
I am American but all 3D printer temps are in metric so I got confused when you said you annealed at 200 degrees. I had to convert that to 93C to relate it to what others have said about annealing.
You are making very interesting videos. Thanks for the tests. But a little question. I come from the German-speaking area ... Why are German subtitles not available in your Videos? Thank you, all the best!
question, I just started out 3d printing and i currently am using PLA+ from Esun. I print at 210C but i want to test it out with a temp tower. Problem is all the ones i see start at 190 and go up from there. According to Esun PLA+ range is 205-225 degrees. is there a temp tower out there for that, or is this something i can just do in prusa?
Normally, when i want tougher, functional prints i use PETG instead PLA, but haven't tried pro, performance or PLA+. Edit: just came to my mind, should test PETG as well! PETG is nowadays one of the most popular materials!
CNC Kitchen has extensive tests on his channel. Lots of different brands, different materials, different printing orientation, different use cases (like bending vs impact vs pull strength). His channel might be more your speed and might satisfy your curiosity
Hi there , I really need ur help , I’m new to 3D printing , my problem is don’t matter what I do , anytime I pause my prints to swap filament, the nozzle don’t rise up , it stays on the print , i have the new ender 3 with 4.2.2 board
Problem I'm having problem with my printer ple give me sotution I can't find any My printer is printing edhision layer then it goes up in air about 2- 3 mm and start printing what is the problem
Hard to say without more information. But I have a place where over 1,000 DrVAX viewers hang out and answer questions. I have started a new discussion forum at forum.drvax.com where we can all have more elaborate discussions and share pictures on our prints and printers. Check it out. This would be a great place to get your question answered. Irv
Hi DrVax, no need to apologize for the glare on your glasses or your mechanical terminology :)
Your videos are very helpful as always
Your videos are so informative! Thanks for doing these tests.
Thank you!

Quite interesting. Thanks for the comment from a professional.

I agree. Not every experiment produces the results you expect. I will be doing more testing of filaments over the summer.

We re-learned that twigs snap. :) :)

Thanks Dr. Can you do a cold-flow test on different filaments. ABS PETG & PLA?

Hi, can we somehow raise PLA glass transition temperature by painting the print or some other post processing ?
Good video.
Also mention how many fumes come out of the strongest filaments and bad brands. People need to know this things.

Problem
I'm having problem with my printer ple give me sotution I can't find any
My printer is printing edhision layer then it goes up in air about 2- 3 mm and start printing what is the problem
I have an ender 3 max this is my first printer
