Solid comparison video, appreciate how straight forward and to the point it was, thanks for the info.
Thank you for the simple yet educational video. Great to see how the PLA did in a real situation rather than a theoretical experiment. I couldn’t believe how much the PLA disformed in such a short amount of time. I really enjoy your practical 3D print videos so please keep them coming!
Thank you, I really appreciate it!
This video just answered a question iv been trying to search for about 4 days now in 3 mins. Thanks lots
I don't doubt the effect of the heat but I cannot see how the PLA one sagged to a level below the pet version, the lamp housing was in the way. It would have to force its way past.
That’s exactly what happened. Meanwhile the PET version has now been in my yard for going on 3 summers and still looks like new.
@@ALLYOURTECH3DP this update helps a lot
I was going to say that too. Glad someone else realized there was something fishy going on in this “test”
Love it! So cool to see the real-world expeirence! Been having PETG issues, will check out your other videos too! :)
Awesome! Thank you!
prob one of the simple yet easy as pie to understand the difference without a 10 min video saying who sponsored their vid! awesome video man, clear as day now for me the difference! thanks!
Very kind of you to say that, i'm glad it helped!
Thank you so much for the differences between the to materials. Please keep doing what you are its awesome.
New with this 3D stuff ......It's March now and it should be fun to see what happens out here in the Phoenix AZ sun this summer.
Just got my first roll of PETG
Thanks, I design and print things for my motorcycle and found that if I print in white or silver PLA I have no melting issues, Even here in a HOT LA summer.
Hey BLOVE, great vid and channel. Exactly what I was looking for. Do you think 100% infill would have made any difference in the PLA performance? Maybe slightly less warping. Lol
Thank you for the information. I had been disformed previously.
I'm printing large long fins for outdoor in Florida.
What PET or PETG would you recommend for fast printing with low or no shrinkage?
It also has to survive the Florida sun (painted).
Great video man! Thanks for sharing!!! I actually learned this the hard way when I printed a cover for my diy quadcopter. After an hour in the sun it looked like melted icecream. lol
Did you reprint with petg?
Great video mate!
Glad you enjoyed it
Use ASA filament when use outside it´s UV protection and can handle hgh temperature
It's kinda crazy to me how inconsistent results seem to be across videos, vs my own experience. Makers Muse showed a video of a number of PLA prints, 1 wall vases, lasting over a year and the main things that hit his were discoloration due to UV. I'm in the pacific Northwest and have had my prints out for 9 months (3d models/lawn gnomes) but they've been primed, and they went through snow, rain, and now 85 degree days for spring and part of summer with no warping. I'm researching before my next video to see what others see, and so far it seems like everyone's seeing something different. I wonder if it has to do with it being non-primed/painted, or if it's because it's functional, or the brand PLA, etc. Thankyou for this video it's a great data point..I'd definitely recommend PETG for functional prints outdoors. I am just wondering if I got lucky on my PLA prints or if possibly priming/painting is affecting the temperature resistance that greatly.
Don't forget PLAs weakness is heat. Black obsorbs light and converts it to heat. A different colour of PLA would of had a better chance.
Ty for sharing this video I was wondering how well petg would hold up and it did really well. Now I need to buy some
very good video explanation, thanks so much.
Hi, would it have been better in white
To reflect the sunlight. Cooler
last week i have print a mirror holder part from petg. sadly it melted in the car and lost its functionality. i will try abs.
By the way your videos are great, totally underrated channel. subscribed! :)
Hey BLOVE what infill did you use?
Excellent experiment. In my previous projects, every time I
tried to machine PLA, it turned into mush because of the heat. That’s why I prefer PETG for the functional
parts. Always good to see the real thing happening before your eyes. Great
video. It proves the point.
Well black obsorbs sunlight and converts it to heat. A different colour PLA would of held better.
'preciate it!
To clean up the experiment, a good suggestion for folks would be to have the PETG by itself and to recreate the comparison with the two beside each other, but on the other side.
Thanks for the tips!
Hey Brian, Will a Prusa Mini suffice for functional prints? I've been looking at your channel and see that you've printed a few great functional prints. Have they all fit under a 7 in cubed sized?
For most prints a Prusa mini would be fine. It’s a great printer!
BLOVE thanks! Keep up with the uploads Brian! You are goals 👍🏽
I do not find the links you mentioned for getting started with PETG.
PETG starts to melt and bend around 80 degree celsius. Due to its ease of use, it is the preferred option for those who need to print outdoor objects. Still, ABS or ASA are the best filament options when the goal is to withstand high temperatures. ABS and ASA begin to deform only above 120 degrees. The flexibility of PETG is also an undesirable characteristic in certain types of use.
I'm curious what the differences would be if you used a lighter color that wouldn't absorb as much light and heat. Would the PLA last longer? Would the differences between it and PETG be less-stark?
Sounds like another experiment is in order.
Yeah I just commented the same before seeing your comment.
Maybe a gray color instead of full white of pitch black
Nice video! I'm still trying to master PETG
I enjoy 3D printing too, but I'd have made those brackets with two chunks of cedar fence board and a couple nails. 2 min with a hole-saw and done. A fraction of the cost and time and a better fit for the all wood gazebo. Sometimes I think we try too hard to find uses for our 3D prints.
Hello Brian, did you leave the petg part outside since the video and how has it been doing since then?
I have been using those parts outside since shooting the video. The PETG hasn’t sagged at all. It looks just as good as the day I put it out there. Really happy with the performance
That's good to know, petg is cheaper per 1kg as of the time I checked. Holiday sales, across most online retailers.
From other heat filament experiments, it showed ASA being even more heat resistant - by a large margin, than PETG.
Good demo video
Was this regular PLA or PLA plus?
Hey there Blove! Love your videos! Currently building the Not A Flamethrower, and I was wondering whether I could purchase a printed Boring Company Logo from you? Don’t got a 3D printer, so I would truly be eternally grateful :D
Send me your shipping info and I’ll send over a couple (brian.c.lovett@gmail.com)
BLOVE Oh God bless you! I’ll do that promptly, could not thank you enough.

i want to make AQUARIUM DECORATIONS that will contantly be under water in FISH WATER... Can i safely use PLA without concern of dissolving in the water..
Good question. I haven't tried that personally. I have used PETG for both flower pots as well as hydroponic systems, so I believe it would handle the water just fine. PLA tends to leak, but that wouldn't matter for your application.
I realised black PLA always warps. However white PLA almost always have little to no warping. A simple experiment, touch a black PLA cube under summer sun and it will hurt to the touch while a white PLA placed beside it feels almost neutral to cool. The black colour literally absorbed so much heat it melts itself.
Exactly. White reflects heat, Whereas black absorbs it. I have placed my parts under sun for 3 days and most of them are good. Except for a few smaller components. They deformed a bit. But the infill and wall perimeters matters. In my prints when I tested, Prints without infill deformed more than the ones with infill. 3 walls and 20% infill is strong enough for mine.
Yes. I noticed it too. Black PLA gets kind of soft when being warmed while other colors stay solid. I think it has something to do with the color the manufacturer adds
PLA is better used to produce indoor, figure, modelling, PETG much more is used for outdoor and closer to ABS industry prototype modelling.
Hey, do you know the concept of creep (deformation)? Because that seems to be the case here. PLA has this biggest downside of creeping that's why it is not advisable to use for functional parts or any applications that are subjected to stress. And they don't even have to be in a hot environment to creep.
How's the petg sconce holding up after a year? Or is it broken?
It has been about a year now, and all 4 sconces look as good as the day they were printed. We had record heat all summer and they didn’t move at all!
@@ALLYOURTECH3DP nice. Thanks for reply
Weird... I made an object to hang, using PLA+, it has a couple of tabs maybe 4mm thick and a hole for a wire, and this supports the object below (100g maybe) - I decided to strength test the loop, but only succeeded in pulling the screw out of the wood that was holding the apparatus up. So I mounted it outside, with 10kg of rocks in a bucket hanging from the loop. Its still there 8-9 months later, no warping/sagging, through an entire Australian summer too..... Other PLA+ parts in the garden have held up well too....
Pla+ does seem to hold up to higher temps better than pla. Curious what color your print was as well? I am going to run a similar test with lighter color filament.
@@ALLYOURTECH3DP Its a tan colour, light brown...
I've had mixed results in the sun with PLA+. Some smaller, more rigid and higher infill parts (like RC car axles, wheels, hubs etc) seem to hold up fine after days and days , but larger panels and body sections of PLA+ (with less infill, granted) will deform quickly.
Have you thought of anealing your prints for outdoor or practical use for the extra rigidity?
So far I haven't needed to do anything extra outside of selecting the proper material. I may need to give that a shot though just to see what happens.
@ALLYOURTECH3DP thanks for the response!!! This was a pretty old video so I appreciate that!! Also I've just had a lot of bad luck printing ABS. had to buy a new extruder assembly since the last one was swallowed by a 1 days worth of filament lol.
Gotta wonder how white or a print painted a lighter color or metallic would do. The problem here was pretty clearly the heat gain from direct sun exposure which is going to have a bigger effect on black colored objects.
Sounds like something I need to test :)
@@ALLYOURTECH3DP FWIW, I made some little T-beam test objects and put them in the Arizona sun to see how they'd melt. None of them warped a bit. Black PLA - just fine in 110F July sun. OTOH, my bike helmet visor melted in 10- 15 minutes in direct sunlight. How well a part deals with the heat from the sun is going to depend on how its shape absorbs sunlight and how it sheds heat. My little T-beams had a lot more radiant surface on the lower side to radiate heat and not as much on top to collect it. They were also solid, so the heat collected on the top could pass through to the lower surfaces. There was no insulating air gap that would isolate the top surface.
So my bet is that your torch supports had relatively thin walls and light infill - like my visor. If instead the back of that part was made of a few vertical rails that were solid or nearly so and that allowed for air to pass up and through, the warping might go away or be reduced.
PETG that I left on my car dash became floppy - almost like it was cloth. That was probably at a temp of around 160F. ASA and ABS, OTOH, withstand being dipped in just-boiled water. PETG goes limp in that almost immediately.
Anyway, like you have shown, PETG is clearly more heat resistant than regular PLA. But it is also pretty easy to run into its limitations in hot environments.
and PLA+?
In black it get very hot with direct sun light...
Just ordered 8 rolls of PETG.
Should try with pla+
Painted ABS FTW on functional outdoor prints.
I haven't made the leap to ABS other than with my 3d printing pen. Fortunately, after redoing these sconces in PETG, they have held up the rest of the summer through 100+ degree days.
@@ALLYOURTECH3DP That's awesome, I live in Florida and it's good to know PETG will survive outside. 👍
Wow, that's quite a lot of warping!
With petg you should spray some kind of uv products
Maybe i've been lucky, but i've never had discoloration issues or anything else with PETG. My wall sconces have been up for going on 3 years, and I have a dozen or so orchid pots that are also PETG/.
ASA is a really good material, to use for this
I need to try a few prints with ASA. I've been meaning to give it a shot.
It's also toxic?
You didn't link anything.
Good test though.
The black color was either a horrible choice or a good choice.
I wonder how much different would the results be for a white color, since it's not going to heat up as much in the sun.
Going on 3 summers with the black PETG prints outside through summer and winter and they still look like new. I just don’t trust pla to hold up, and PETG is easy to print.
Wow good to know I printed a part for gold prospecting in the desert. Good to know ahead of time that it's gonna fail in Arizona desert...
Yeah, chose your material wisely!
So sad that battery died on time lapse.. :(
80% of my filaments are PETG!
I know, died right as the print started to sag. I need to get an external battery I guess haha!
BLOVE yeah... or usb Charger, that’s what I use..
Okay…the whole time I’m watching the prints trying to see if they are solid or hollow with bones….hmmmm…(my OCD is showing…sorry for obsessing during your great video…I went back and watched for fun AND information..
Haha! Thanks for watching
I'm absolutely agree that PLA is worst choice to print something for outdoor usage. But why you used just two screws? Not four. I understand that it could not help but...
I used 4 for the permanent installation of the PETG pieces which have now been outside in the heat for over 3 years.
Would petg be functional inside a car?
It is, it's actually ideal for that application because of the higher melting point. PLA will likely only last a few hours on a hot enough day.
I think your 3 inch screws were clearly too short. Maybe go for 4 inchers next time.
exactly
Nice t-shirt
Ethereum!!!
What about ABS?
Abs would work as well. It handles high temps well, and has great mechanical properties. I didn’t use it because I didn’t have a printer at the time that was able to print it.
PETG is hands down superior for this kind of task, but to be fair, you used black when testing against the sun.
Sure, but also to be fair, the black PETG has held up fine :)
@@ALLYOURTECH3DP Because PETG can withstand higher temperatures. I doubt white PLA would of warped though.
ASA is best for outdoor!
I haven't printed with ASA yet since PETG has been holding up well, but need to try it out! Thanks for the tip
"Squirrel!"
Damn squirrel! lol
Dude, why on earth did you print in black something that staying under the sun and soften from 60°C ... ??
PLA is weak against UV and outside environment. However, it gets better mechanicals results.
As I said in the video, at the time, I was out of PETG. After a full summer in the hot sun, the PETG has held up great and looks as good as the day I put it out there. It's an example of why material choice matters.
@@ALLYOURTECH3DP I would have ordered a New filament in tour shoes, but let s say it is a nice illustration of what works or not, supplying your content 🙃
80-85° is damn hot!
Like, water boils at 100, right?
Should have specified, it’s Fahrenheit since I’m in the United States (the only backwards country that doesn’t use metric)
My europeran ass was like "85 DEGREES?!"
1st
Algorand is better mhm ditch the 0 and get the hero and that's ALGORAND ! boom baby !
i can not for life of me print petg
I have a couple other videos on the subject that cover settings and such. I can almost guarantee it will get you successfully printing petg, and then you will print with nothing else :)
I call BS on the battery dying on the camera
Go test it for yourself. I’ve also done the same test with pla plus on the channel.
