The recommended bed temperature for PLA is 70C. Having your bed level and extruder at the right height is extremely important when printing on glass.
Warping occurs due to material shrinkage while 3D printing, which causes the corners of the print to lift and detach from the build plate. When plastics are printed, they firstly expand slightly but contract as they cool down. If material contracts too much, this causes the print to bend up from the build plate.
You can 3D print in a cold or hot room as long as your 3D printer has the proper conditions, such as a constant printing temperature and the right kind of materials. If you try to 3D print ABS in a cold room, you are likely to run into massive warping problems, while PLA could be pulled off.
What's Causing this 3D Printing Problem? The most common cause is simply that the print just doesn't bond to the surface of the print platform. If the platform is uneven then for some parts of the print the nozzle won't be close enough to the platform to correctly extrude and bond the first layer.
Physical strength is generally higher with PETG compared to PLA. Temperature tolerance is typically much higher with PETG. Some extreme PETG blends like Arnite 3040 from Nexeo 3D can handle peak temperatures of up to 250 °C. However, a more common tolerance for PETG is around 75 °C.
PLA (Polylactic acid) is not water-resistant. The bioplastic material is derived from plants like rice, potato and corn. If you left PLA printing material in an open place, it will take a few months to degrade into water, methane and carbon dioxide.
PLA also will slowly melt in direct sunlight.
PLA plus is a slightly modified version of PLA that eliminates some negatives of normal PLA. With PLA plus this can be avoided. PLA plus have is said to be much stronger, less brittle, more durable and has a better layer adhesion compared to PLA.
We probably could have eked a few more pounds out of it, but the hook was already yielding. Truth be told, we were surprised with PLA's strength. However, with a tensile strength of 7,250 psi, this is a strong material.

Neither ABS or PLA will degrade much in water. PLA is biodegradable, but it is what is known as chemically biodegradable, meaning it does not biodegrade very fast. ABS, PLA, and Nylon all are hydroscopic, but that does not mean they will absorb a bunch of water and then start degrading.
To be clear, PLA+ is still PLA, as it has the same fundamental composition. The additives just give it a boost. The additional properties or specific additives change from brand to brand, as does the name. The principle, however, is the same: It's PLA but better.
PLA isn't UV resistant and will be negatively affected by sunlight over a long period of time. ABS has better UV resistant qualities, but one of the most UV resistant filament is ASA, which is an alternative from ABS.
