So we have some seriously hot days out here. Enough to deform PLA in the morning hours.
I’ve experimented with ABS and PETG, I intend to avoid ABS in the future though. Them fumes are no joke.
I have heard of PLA+ and many people recommending it as a replacement for PETG. I need to know if it can handle the heat (ideally 80C-100C).
So my real questions:
Do people prefer PLA+ or PETG for this temperature range?
Which brands of which are ya’ll’s favorites?
PLA+ requires annealing in order to properly be heat resistant.
PetG does not.
PetG is more difficult to print though.
I tend to use more PLA then PETG but do get in spurts of petg prints.
Matterhackers filament FTW
Oh yeah, protopasta almost exclusively has pla+ (HTPLA) and an amazing beautiful array of colors to choose from. great quality.
they even have a subscription that every 2 months you get 3 different unique one time colors i signed up for recently.
Unfortnaly the shippingcost to Germany would be very to high for me 
bummer, it is really nice stuff
found two spools on amazon each about 90 Euros 
I looked at protopasta’s sub. Unfortunately I can’t justifying 75$ for 1.5kg of plastic. I’ll give matterhacker petg a go this time around.
How about: Prusament ASA | Prusament
Haven’t tried this particular one but all of their others are top notch.
They’re Czech so shipping to Germany shouldn’t be a problem.

From the Department of Total Overkill:
If you have a rich uncle die suddenly and leave you a pile of cash, I think this stuff is (just barely) within the printing capability of the Snapmaker: DSM Arnitel 2060-HT High Temp TPC Filament - Black - 1.75mm | Filaments.ca (you’d want a different supplier, of course). Good for sustained use at 190C, according to the manufacturer.
Ok, maybe I’m weird for not jumping to conclusions immediately. What kind of deformation are we talking about? What are you using the parts for? They deform just by standing in the shadow indoors. Because you place it behind a window in the sun? Because it’s a functional part in your car that’s parked in the sun?
Are we talking about functional parts losing strength or tiny little statues that start decolorizing? Depending on the actual problem and needs different solutions may apply. Like coating them with a UV & heat resistant layer for example:
I should capture a timelapse on the next hot day we have come summer. PLA will just deform as in it starts to curl up into a ball and lose it’s shape.
Left it open as I plan to use it as a general purpose filament. i.e. everything from dnd terrain to water hose attachments left outside all day every day to replacement parts for any plastic that breaks in the car. Even making toys for my nieces and nephew is asking for trouble in pla if they’ll melt come summer.
I don’t need it to be super great for mechanical purposes, just print easy, be heat tolerant, and retain it’s shape under mild pressure (mainly for the toys, kids are mean to their toys!).
Well for some of the functional parts, the coating in the video might actually be useful.
The “easiest” to try is PETG (and probably white would work best as it reflects more light/heat). PETG isn’t that difficult to print with in my opinion. I have very similar results as with PLA. It’s a bit more “snotty” so the first layer might take some practice but once it’s printing it usually goes really smooth. Doesn’t need a heated enclosure either.
It’s a little less stiff than PLA (and ABS) and depending on the part, that might be an advantage/disadvantage. But it’s the same material water bottles (PET) are made off, so fairly safe to hand over to children I guess.
ABS is probably stronger and more suited for some applications, but I don’t think it’s very UV-resistant and the colors might fade really fast. But you have the challenges printing it and the fumes that come with it.
My first suggestion would be to try PETG and/or coat it with something that helps with the UV-resistance & temperature.
And I know from personal experience that kids will find a way to break it anyway, it’s mostly a matter of finding a way to delay it as long as possible and if it does happen causes the least damage. And in that sense PETG is usually ok as it tends to bend more before it breaks. (depending on print orientation this does not necessarily mean it lasts longer, but the failures are less “abrupt”.
May I ask you in what a wonderfull 
country you live in?
Been a while since anyone’s called us wonderful XD. America.
death valley?
hehe i dont usually have any problems with any PLA deformation until 120f or so.
Tought of Austraila or Sahara or something like that
Summer temps of 110ºF / 43ºC are common where I live (inland southern California, US), and I’ve seen as high as 117ºF / 47ºC. The inside of a car parked in the sun easily exceeds 150ºF / 65ºC.
I haven’t had any problems with PLA outside the car, but PLA doesn’t last inside the car.
I live in Las Vegas. Very similar temps. I haven’t had any issues with Hatchbox PLA. That said, our use cases may be different and most of my stuff doesn’t leave the house.
I live in Florida now. Did the whole SoCal thing, Vista and Encinitas. Only reason it was ever hot was because the local landlords don’t believe in AC.
Las Vegas I can’t vouch for as I’m 99% positive the city doesn’t exist except at night…and anybody that says otherwise is your wife’s PI. 
I do imagine the days get pretty warm though but never saw the town when the sun was out.
Not sure if it’s a combination of factors (it’s not unheard of to have 110-115f and 95+% humidity) but I’ve personally watched a PLA print wrap itself up into a ball under the heat on my back porch. I’ve also seen it happen while living this in Texas, but that was like 6 years ago? Back on the Ultimaker before they added the “Original” branding.
