I tested with my tensile testing machine how the printing temperature changes the strength and properties of your 3D printed parts.
I printed almost 50 specimens at temperatures between 180°C and 270°C to investigate exactly that!

Fun fact: 9 out of ten times I print with ABS, but a week ago I accidently ran a batch of parts with a spool of PLA loaded but on my black ABS profile: 240 deg C nozzle and 105 deg C heatbed. It was the best and strongest PLA I have ever printed. This is a great systematic channel, keep it up!

@ThatJay283 Год назад

based on that bed temp i reckon you would've gotten some nice elephants foot on those parts too lol

@hegedusrp 5 лет назад

You should make video similar to this but with fan speed. It efetcts both layer adhesion and print quality so it is very important to get it right!

@MrChangCJ 6 лет назад

interesting! thank you for taking the time to perform these tests!

@JamieBainbridge 7 лет назад

It was known before that higher temp gives better layer adhesion, so parts are stronger against the layer direction. However the difference printing with bed on and off is pretty amazing. Now one can choose between stronger parts which snap at failure, or slightly weaker parts which stretch more before failure. That's really cool! I'd also be interested to see the effects on compression strength and bending strength perpendicular to the layer direction.

I'll do that. Just need to organize some proper filament. Just have crappy Hobbyking ABS at home.

@habiks 7 лет назад

Maybe do a different layer-height vs layer strength comparison as well? Also I was complaining to local pla manufacturer other day that the black filament is coming too transparent / bit purple on in bright places and he said he doesn't want to add more pigment as the strength would degrade.. transparent vs pigmented one?

For the temperature tower you can use the temperature settings in Simplify3D instead of processes, i.e. by setting the temperature changes depending on the active layer number. I used this approach when printing some temperature towers to change the temperature from 230° to 170° in 3° C. steps.

@zentriceggofficial 6 лет назад

Good investigation! I had terrible bed adhesion a week after building my Prusa mk3 i3. None of the forum advice or manual suggestions worked. It was by chance that I downloaded a user made calibration model for the mk3 and that had a print temp of 235 for the pla. Bed adhesion was perfect. So I started setting 235 for the first layer on my own designs and the bed adhesion is perfect. I should also say that the bottom layer of my models showed separate filament lines and the detail was always bad on first layer regardless of how many times I recalibrated. Since setting 235 for first layer the bottom of the print model is perfect.

@uint16_t 5 лет назад

Mysterious MrX have you tried cleaning the bed with isopropanol or acetone?

@zentriceggofficial 5 лет назад

I was using isopropanol at the time. I now use acetone and noticed an improvement. I set the first layer print speed lower as well. Much better results these days. :)

I tried some of the PolyMax PLA and it is super durable, a bit too durable...trying to remove supports was a failure. I doubt it is much stronger than regular PLA, but it does deform more before breaking. Good job on your tests and thank you for doing this.

I've already had overheating issues while printing at 195°c on my monoprice mini delta. If I need a very strong part, I think I'll print at 210 degrees with a fan blowing on the print and the printer runing very slowly. I'll also anneal the part. For now, I don't need such a part, but this video has provided very valuable info in case I do ever need such strength in a 3d print.

@BrentSimpsonEnhance 6 лет назад

@meky0 7 лет назад

ive done same testing and chosen 220 for e3d v6 for max layer bonding and overhangs also. also the hotter it is the easier it flows, so less stress on the e-motor i approve of your findings. PETG is my go-to filament now please do the same test like 99999 people have asked.

Hallo Stefan, vorab, meinen dicken Respekt zu dem wohlverdienten und hart erarbeiteten Erfolg deines Kanals. +200k Abonnenten in 3 Jahren, echt beeindruckend. Ich habe selber auch einen (ganz) kleinen RU-vid Kanal, und kann mir vorstellen, dass der Aufwand, alles in dieser Qualität zu dokumentieren, filmen, schneiden, vertonen, illustrieren...bestimmt ähnlich groß ist, wie das eigentliche Thema, dass du fachlich beleuchtetst. Ich bin ähnlich wie du, auch gerade dabei, Zugversuche durchzuführen, allesamt ausschließlich auf die Layer Adhesion abzielend. Ich schätze auch sehr deine systematische und wissenschaftliche Vorgehensweise. Ich hätte einen Themenvorschlag für dich: wenn man sehr große Teile druckt (Zeit pro Layer

@jimax2039 3 года назад

@donaldlightfoot7968 6 лет назад

I might take a look at the infill pattern some day. Also the 100% infill is usually not realistic. I will try to come up with another test there.

@IchBinBartlos 5 лет назад

you can also ramp up the temperatur at specified layers within one process, so you can accomplish a heat tower within one process

@xXxZystxXx 5 лет назад

In symplify3D you can set temps for each layer in one process, no need to make 6 of them for 6 temps, I do this to print the first layer hotter for better platform adhesion.

@TheNitroG1 5 лет назад

2:30 Tip about simplify 3d you can actually figure out the height steps by clicking on view>cross section. the slider will show you in preview the exact height of each slice.

@TheNitroG1 5 лет назад

I use multiple processes all the time. it's a major time and material saver if you know what you are doing. Now I just need the ability to select specific sections of a model to change properties. it would be amazing to be able to have different wall thicknesses or infill on different sections of the same model.

@swengross46 6 лет назад

That's actually nice to see, that PLAs tensile strength peaks at aprox 230 degrees. Im looking for a stressable, more eco-friendly type of material that works with HIPS (230°C) to support structures (ABS and HIPS are the commonly - if not the only - mentioned combination). The printing results, as shown, are quite good also. Valueable information that brings me closer to a buying decision. thanks

I know this video is 2 years old, but I recently got a MK3s and measured the temperature with a laser thermometer while printing. The heated bed also showed ~5° more on the display than it actually was

@alang6402 7 лет назад

Very good and informative video - thank you. With the annealing test could you comment about dimensional stability and warping. For warping I suggest comparing say a plain rectangular prism with a long end 8-10x the other longest side as a control and a similar sized piece with a semi-circular notch half way along reducing the cross section by 50%.

@CNCKitchen 7 лет назад

Very good idea!

@trischas.2809 7 лет назад

I strongly wish to hear more about the annealing/sintering: how much can I increase the layer adhesion between Z-Layers by baking it?

@tareql1906 7 лет назад

The varying strength results on the z axis are probably due to the adhesion surface area. Printing upright vertical reduces the surface area hence reduces the strength. Nice work :)

If you're only varying temperature, you can go to the "Temperature" tab and simply set multiple set points instead of making whole new processes altogether :)

@ironfitz8626 6 лет назад

@frankfnhallukhall4520 6 лет назад

Hi There. Love your videos! I'm a bit of a scientist at heart and your methods for testing the tensile strength of printed plastics is much better than I was expecting from a simple youtube video. I'm very interesting in the annealing process and I've watched loads of videos but no-one tests the strength of the plastics like you do. Would you mind doing a follow up video to this one where you print a number of PLA specimens and anneal them under different conditions with the aim of finding the best conditions that yield the maximum strength.

@frankfnhallukhall4520 6 лет назад

Would you mind also testing pieces printed with different fill directions and increasing the number of skin layers so that all print lines are in line with the test direction (effectively leaving zero fill). Printing with different nozzle sizes would also be interesting to see if this effects the strength of the part. I've actually got a suspicion than when annealing, the part becomes thicker and deeper, but loses some length. Of course it's the cross-sectional area that determines the strength so factoring this in might effectively reduce the strength per area but until we some some hard numbers it'll be difficult to say.

@CNCKitchen 6 лет назад

The temperature only really changes the rate of cristallization. Low temperature: longer annealing process, high temperature: shorter time.

@frankfnhallukhall4520 6 лет назад

CNC Kitchen . So the data you present for "Annealed" is the best strength that PLA can obtain? How long did you leave your pieces on the print bed for, at 60°C? Edit: And have you got data for annealing pieces that are stood upright?

@CNCKitchen 6 лет назад

I put the pieces in the oven. You should go well above 60°C. Strength is not necessarily better. They are stiffer and stronger but more brittle. Your choice, what's more important for you. Have no data at the moment about upright ones, but the layers don't fuse together during the process.

@aaronevan4065 7 лет назад

In simplify3d control k will bring up a menu where you can find where the heights are so you can do it all in one program.

@JamieBainbridge 7 лет назад

If your temperature readings are inaccurate, tune your PID values. The ones in the firmware are probably pretty accurate but every printer is different and every environment is different, so best accuracy is gained by PID tuning. Tom Sanladerer has a good video about it.

@CNCKitchen 7 лет назад

+Jamie I know what you mean. My first video ever was actually about that. But PID tuning will not make the temperature readings more accurate it only improves the control loop to make them more stable. The calibration table for the thermistor in my opinion is not perfectly right.

@drewpickard554 7 лет назад

with s3d you can use the cross section view to get the heights fyi

@cosmicrdt 7 лет назад

Great video. Did you also consider ambient temperatures and humidity? In my city it ranges from 0 degrees in the winter up to 40 degrees in the summer.

@CNCKitchen 7 лет назад

This should actually only influence the moisture content in the filament which would reduce the usable temperature region and make it more brittle. Even though the filament was already open for 5 months and I stored it in open air it was winter, so usually low humidity and temperature. I'm planing to make a video about material aging where I want to exactly test that.

@hexane360 5 лет назад

Do you have the full stress-strain curves for each condition?

@MidnightGazebo 7 лет назад

Really interesting work! Are you considering writing a paper of your own based on your study?

@CNCKitchen 7 лет назад

I might do that, but unfortunately the machines and the number of specimens I use might not be scientifically enough. But if I have enough results I might write everything together and publish it somehow.

@marcoguada42 5 лет назад

Nice video man, I managed to print with my 16€/kg eBay PLA some good Zstrength things but I'm sure that a good PLA would print the same thing but with at least 10°C less, that's were a good PLA spool differ from mine. Also turning off the cooling did the trick, did you have any video test or chart about that? Keep up the good work.
