How does PETG hold up outside?

PETG and ASA are filaments for outdoor use

Thanks to the high resistance to deformation these filaments remain solid in wind and sun. Despite the sun's UV rays, 3D printed parts made from PETG and ASA do not significantly change or fade color.

How long does PETG last outdoors?

Several of my PETG prints for outdoors use have deteriorated over the course of about 1 year. Initially, the prints are strong and have that characteristic bit of flex that you'd expect of PETG.

Will PETG last in the sun?

PETg filament exhibits high UV resistance – making it suited to applications for the outdoors and / or require exposure to direct sunlight.

How does PETG hold up in the sun?

PETG's smooth finish helps it to reflect most of the radiation falling on the surface and its transparent appearance does not hold any heat energy from the radiation. These properties give it much more endurance from UV compared to PLA and ABS.

Is PETG plastic waterproof?

PETG, a modification of PET, which is used in water bottles, is a great material for making waterproof prints. PETG is commonly considered to be waterproof and also has an excellent thermal resistance.

How does 3D printed PLA hold up outside in the sun?

Does PETG absorb water?

When not in use PETG should be stored away from sunlight and in a resealable bag with desiccant. Like many other plastics, PETG is a hygroscopic material, absorbing moisture from its surrounding environment.

How does PETG react to water?

PETG filament is moisture-resistant, but it isn't completely waterproof. That said, though PETG filament absorbs water, it does so at a much slower rate than other types of filament. So any water it does absorb won't damage its structural integrity.

Does PETG deteriorate?

PETG is noticeably more hygroscopic, easily absorbing moisture from the air. This moisture deteriorates the material itself and can ruin an otherwise fine spool of filament. As such, ABS is much more tolerant of being left out on a shelf.

Will PETG hold up in a hot car?

If PETG is deforming in a hot car, you should reconsider where you're buying it from: proper PETG should be good up to at least 70°C (160°F), and more commonly 90°C (195°F). @Mark not really: it holds shape up to 90 °C, but it loses strength much earlier.

Is PETG sheet UV resistant?

UV-PETG retains excellent clarity, puncture resistance, and impact toughness even after repeated ultraviolet radiation exposure outdoors or as part of the UV-sterilization process. While the color made fade over time, UV-PETG can be expected to maintain its structural qualities and UV-resistance for several years.

Does PETG deform over time?

Warping. PETG has a reduced thermal contraction, so it is not prone to warping and results in parts with good dimensional tolerances. Warping will only appear in large parts, more or less the same as PLA.

Can PLA survive outdoors?

Despite many stating that PLA is not appropriate for outdoor use, which may be true for structurally critical components, the survivability may just be fine for light structural applications.

How long will PLA last outside?

PLA exposed to direct sunlight at ambient temperature can survive for 1 week then it becomes brittle. PLA filaments exposed to more than 60% humidity can be usable for less than a month but can produce bad prints.

What temperature does PETG start to deform?

For PETG, the suitable temperature is about 90-110 °C (194-230 °F). In this range, neither the warping or dimensional changes are too significant. At higher temperatures, PETG deforms gradually, up to 170 °C (338 °F), when it melts just like the PLA.

Does PLA degrade in sun?

So the answer is: NO, PLA will not melt in the sun. Although it won't melt, it will become brittle and lose its tensile strength and impact resistance.

Can PLA withstand rain?

Therefore, if the necessary conditions or chemicals needed to decompose the biodegradable PLA are not present in the environment, your PLA prints will never be affected by water. At worst, it will swell since PLA, as well as most other filaments, is hygroscopic, meaning that it absorbs water.

What temperature can PETG withstand?

PETG Smartfil (1.75mm or 2,85mm) filament is accepted for use in contact with food products use (FDA) and also does not emit odors to be printed. The softening temperature or temperature resistance of PETG is 85 ºC, this is intermediate between the PLA and ABS.

Is PETG cold resistant?

When parts are made for the exterior, the PETG is more resistant to the action of the sun, rain and cold, although there are solutions such as the Plastimperm F10 to waterproof parts manufactured with PLA.

How long does PETG prints last?

Most PETG filaments can be stored for 2 years or more before it becomes brittle and cracks. You should keep it in a cool place and away from moisture or direct sunlight to make sure it retains its qualities as long as possible.

Does PETG need an enclosure?

Overall, PETG is generally very easy to print with, as it requires no enclosure nor heated bed, making it compatible with virtually all FDM printers. It combines ease of printing with great strength and durability, making it a great filament choice for any print.

What are the advantages of PETG?

As mentioned above, PETG has gained popularity for use in modern 3D printers. A polyethylene terephthalate glycol filament prints easily and provides excellent layer adhesion. Low shrinkage rates allow for larger prints than with PLA or ABS, while PETG is also strong, chemical resistant and odourless while printing.

What melts PETG?

Dichloromethane, methyl ethyl ketone (MEK), toluene, and cyclohexanone have all been proven to dissolve PETG as well, yet they are all extremely dangerous and should only be used by experts.

How do you seal PETG?

Applying an epoxy resin to your PETG 3D print is the same as PLA or ABS and you can do it by using XTC-3D. It's a self-leveling epoxy resin which means it will flow and cover the part and won't show brush strokes.

Can PETG be used outside?

PETG and ASA are filaments for outdoor use

PETG and ASA are 3D printing materials for outdoor use and durable (hold over time). Both filaments are insensitive to changing temperatures and UV rays. They are perfect to use in extreme conditions without deforming shape or appearance.

Is PETG stronger than PLA?

It is also more durable than PLA as well as less stiff. Generally, PETG is seen as a mixture between ABS and PLA. That means, it takes the best qualities of both to a certain degree. For example, PETG is stronger than PLA (though weaker than ABS) and more flexible than ABS (though less flexible than PLA).
