Hi Stephen, I work in a warehouse with -30C. The most annoying thing in this temperature is the constant build-up of the static electricity from conveying all the plastic trays. (I think they are ABS). One time my arm almost came off (not really but it went full 180 degree and almost dislocated my shoulder blade) due to the extremely high voltage that was built up in the conveyor system. As for brittleness, its a little bit more brittle but not a huge deal.

The mainboards of 3D printers are not protected to an overload. Suppose Your nozzle can reach max 250° but at -20 (meaning 38° difference) then only effect is that the mosfet will heat up and they usual not cooled. Note if You have to print at 230° then it will destroy the board and the nozzle heating too. The bed, if limited to 100° is even more a problem since the area is much bigger, this mosfet is usual bigger cause an heated bed is a very energy consuming device. Suppose bed 80°, so in reality must warm the plate to 118 °C so heated bed destroyed.

I've 3dprinted my own luggage tags, and have recognized that very cold temps may be a more significant issue for travelers than you might expect initially. Modern jets travel at altitudes where the ambient temperature may be from -20 in the summer to -60, or significantly lower during the winter at northern (and southern) latitudes. Not all luggage bays on aircraft are heated and pressurized, (though that's becoming much less of an issue for modern jets) so it may be useful to know what the characteristics of the various plastics are when cooled to the temperatures of dry ice. I do suspect that it will be more of what you observed. An added question would be what are the long term effects of cooling and warming these materials to these temperatures and 'room temperature' through several cycles. There is anecdotal evidence that taking some metals down to liquid nitrogen temperatures, and slowly bringing them back up to room temperature over a week or so, can improve various performance characteristics. I'm not expecting to see such results in PLA, but it might be an interesting experiment, even if the result is, not so much.

The same cold that hit Germany hit us as well. We got around -20°C here as well. I have an unheated garage I have my machines in, however temparatures dropped only to about -7°C inside. What I do to deal with these temparatures is; You gotta have your printer eclosed and if possible isolated. I made a simple crate 60x60 cm for my prusa with front plexiglass door (7mm) and the rest 18 mm plywood, which is isolated with 4 cm styrodur. This way ambient temparature inside the box gets to roughly 25°C when printing with heatbed at 60°C for a while. As far as it goes for filament - for that I have a separated box (showcase box) with front glass door. This also has 5 sides isolated with styrodur + the front face isolation is removable. Inside I have a washing machine heater hooked limited to a 50W supply, which heats up inside of the showcase box to 35°C on the bottom and around 45°C at top (if I have isolation on the door, otherise I get to 10°C less). At the top I have a hole for moisture dissipation, this way I get to 5-20% humidity inside. I can store 10 filament spools inside, usually the ones I'm about to use for my projects. Both boxes are connected with a "coupler" tube I printed, which has a telfon tube running through it. I had problems with coupler having too big hole, this way when I lifted Z axis, filament got all messed up inside showcase box - went off spool because of backlash and so on, so the teflon tube solved this problem. Oh yeah, there's a spool roller inside the showcase box, which works perfectly for this. Take care

I noticed that my prints were considerably more brittle and the layer adhesion was terrible after I moved from inside my house to inside my trailer in the winter. I would have to heat up the bed and nozzle with my hands to get my printer to the 8 degree safe-to-setting on my printer to even start warming it up. I also had to increase the bed temperature from 60-70 to get decent adhesion in these temps. Once I got a space heater and pointed it directly at the printer the bed and nozzle temperatures stay are usually around 20-30 degrees now and my prints are fine.

IMO an engine block heater is more important than a cupé heater, but both is pretty sweet. If you only have the cupé heater, and there's the tiniest speck of moisture, your windows will condense and fog due to the large temperature delta between the inside and outside of the glass, and you have to run the car's heater to demist. If the engine is cold, then it's only gonna blow cold air, and it will chill down that nice warm cupé in an instant. If you use a an engine block heater on the other hand, you can have your engine and all its coolant up to temp even if it's 15-20+°C below freezing, the moment you start the car. It will start as if on a warm summer day, and save _a lot_ of fuel because its already at optimal temp, so you skip the whole "fat fuel-air mixture" period the engine needs to warm up. And thus your car's heater and AC will be able to blow max heat if you want, from the start. It won't be nice and toasty when you get in, but it can be after a minute if you so desire. And your windshield glass won't be very warm/heated on the inside, so if it's snowing, the snow won't instantly melt and stick to it. You also get to sidestep the whole catch-22 situation where you need the windshield glass to cool down to reduce condensation on the inside and stop snow from sticking to the outside, but your window is already fogged up due to being warm so you need to blast it with more heat to get rid of the fogging,

Makes sense. Consider high carbon hardened (tool) steel, that hasn't been tempered (yet). Through-hardened steel is extremely strong, but with _minimal_ ductility. A sharp edge can shave and cut through large amounts of lesser hardened steel without dulling, but even fairly large cross-sections will shatter if exposed to impact or significant ductility loads. Tempering restores significant rates of ductility at the expense of _a little_ bit of hardness, but the end product is still _relatively_ brittle.

I wonder how the laws of conservation of energy applies to this in a macro scale, also for different fill (maybe even 100% or molding out the materials used) to see the actual material capabilities in addition to 3d printed environment. As far as I can logically see it, you apply gradual strain on a part it'll introduce heat until that part deforms, if the part is cool enough it won't be able to deform as elastically as in hot environment meaning less energy is converted, that made me think it'll 'convert' less energy to elastic and instead will make the material snap, although at a higher point because freezing, well, like water, makes liquid form into more sturdy material. This causes a somewhat of a threshold effect, the material cannot stretch, so it has to snap. Also, on impact the forces are generally higher so you reach that threshold instantly, while a 'hotter' print acts as sort of dampner, so it changes it shape on micro level to compensate for the forces being applied to it. I also wonder what the temperature readings on the parts would be in such scenarios under the stress tests Not sure if any of what I've said here is true, just was having a small thought.

overall PCMAX for the win, great tension strength, and great brittle strength overall. PLA a good second place with great tension strength but much more brittle than the others. I noticed on their website: "When printing with PolyMax™ PC it is recommended to use an enclosure. Recommended to use a heated chamber. Recommended to anneal the printed part right after the printing process to release the residual internal stress. Annealing settings: 100˚C for 2h" I think this would make it even stronger.

Idle question: Printing depends of a good bond between the layer being printed and the previous layers, no? You might get away with low ambient temperature printing with a modified printing head. Yes, you still have your extruder and all that, but by adding a low powered laser [500 mw-ish], you could heat the previous layer directly ahead of the printing path. Previous layer would get softened/melted, fuses well with new printed layer. As a bonus it would not require the model to be at an elevated temperature during the entire print. Since only a very small volume of the model is heated at any one time, could warping be lessened? Eliminated? More interesting, would rapid cooling due to low ambient temps affect the properties of the plastic being printed? Metals have grain boundaries and all that. Hardening, tempering and annealing all re-shuffle those grainy guys. Do plastics have such tendencies? Does really fast cooling make the plastic denser, or less so? Post processing at low temps? There are 'cryogenic steels', their grain structure compacted by liquid nitrogen soaking after fabrication. Great methodology, by the way!

Really hard to get dry ice here in Germany if you're not living in a big city.
