Imagine this: you've spent weeks designing and perfecting a 3D printed masterpiece, only to realize it starts to crumble after a few days outside. Sound familiar? This is where the importance of choosing the right filament for outdoor use comes into play. 3D printing has revolutionized the way we create and bring our ideas to life, but with so many filament options available, it's essential to understand their unique properties and choose the right one for your specific project. In this guide, we'll take a closer look at three popular filament materials - PLA vs ABS vs PETG - and explore which one is best suited for outdoor use. Get ready to ensure your 3D prints stand the test of time and weather the elements like a pro!
PLA filament for Outdoor Use
PLA (polylactic acid) filament is a popular 3D printing material that is made from renewable resources, such as cornstarch or sugarcane. It has a low melting temperature and is easy to print with, making it a great option for beginners. Additionally, it has a glossy finish that makes it a popular choice for decorative prints.
One advantage of PLA filament for outdoor use is that it is biodegradable and environmentally friendly. This means that if your outdoor print does eventually break down, it won't harm the environment as much as other materials. It also has a relatively low shrinkage rate, which means that prints will maintain their shape and size over time.
However, there are limitations to using PLA filament for outdoor applications. For example, PLA is not very heat-resistant, so it may warp or deform in hot weather. Additionally, it can be brittle and may break under stress, such as in high winds or heavy rain. An example of this is if you were to 3D print a birdhouse with PLA filament, it may not hold up as well as it would with a more durable material like ABS or PETG.
Overall, PLA filament can be a great option for outdoor prints that don't require high durability, such as decorative items or garden accessories. However, if you are looking for a material that can withstand harsh weather conditions, you may want to consider other filaments when looking at the features of pla vs abs vs pet-g vs tpu

Pro-tip for PLA filament for outdoor use: To enhance the durability and weather resistance of PLA prints, consider post-processing techniques such as coating with UV-resistant paint or applying a weather-resistant sealant. Additionally, using a higher infill percentage and thicker walls can also improve the strength and durability of PLA prints. Finally, storing PLA filament in a cool, dry place can prevent it from absorbing moisture and affecting its printing quality.
ABS Filament for Outdoor Use
ABS filament is a popular thermoplastic material that is widely used in 3D printing. When it comes to outdoor use, ABS has some unique properties and characteristics that make it a good choice for certain applications. ABS filament is known for its strength and durability, as well as its resistance to heat and chemicals. These properties make it ideal for outdoor use in a variety of settings.
One of the advantages of ABS filaments for outdoor use is its ability to withstand harsh weather conditions. ABS is highly resistant to UV light and can maintain its strength and color even after prolonged exposure to sunlight. This makes it a great choice for outdoor products like garden furniture, planters, and other decorative items.
Another advantage of ABS filament for outdoor use is its flexibility. ABS is a very flexible material, which means that it can withstand the impact of high winds or other external forces without cracking or breaking. This makes it an ideal material for outdoor applications like housings for electronics and other devices that need to be protected from the elements.
However, ABS filament also has some limitations and disadvantages when it comes to outdoor use. One of the main limitations is its sensitivity to temperature changes. ABS can become brittle and crack in cold temperatures, which can be a problem in certain climates. Additionally, ABS is not as biodegradable as other materials like PLA, which can be a concern for some environmentally conscious users.
A 3D Printing Hobbyist, Denise Chapman created a beautiful Planter using abs 3D print material and Flashforge Guider IIs. It took her 51 hours to 3D Print it but the results are worth it, it's durable and strengthful as per her demands.
Overall, ABS filament can be a great choice for outdoor use in certain applications, but it's important to consider its limitations and potential drawbacks before choosing it as a material.
PET-G Filament for Outdoor Use
PETG filament, or polyethylene terephthalate glycol, is a popular choice for outdoor use due to its unique combination of properties. PETG has a high strength-to-weight ratio, making it strong enough to withstand outdoor elements while still being lightweight enough for practical use. It is also highly resistant to impact, making it a great choice for objects that may be subject to regular use or wear and tear.
One of the key advantages of PETG filaments for outdoor use is its UV resistance. PETG has a natural UV resistance, meaning it is less likely to degrade or become brittle when exposed to sunlight for extended periods of time. This makes it ideal for outdoor applications such as signage, architectural models, and even outdoor furniture.
PETG filament also has a low shrinkage rate, which means it is less likely to warp or deform when exposed to temperature changes. This makes it a good choice for outdoor objects that may experience temperature fluctuations, such as a 3D printed birdhouse or planter.
However, it is important to note that PETG filament can be more difficult to print with compared to other filaments such as PLA or ABS. PETG has a higher melting point and can require a higher print bed temperature to adhere properly. Additionally, PETG is more prone to stringing and requires a slower print speed to avoid imperfections.

PLA vs ABS vs PETG Filaments for Outdoor Use
When it comes to outdoor use, choosing the right filament can make a significant difference in the longevity and performance of your 3D printed parts. The difference between PLA, ABS, and PETG filaments must be looked at in terms of strength and durability, weather resistance, UV resistance, water resistance, and temperature resistance.
In terms of strength and durability, ABS is known to be the strongest of the three filaments, with high impact resistance and the ability to withstand high stress and strain. PETG, on the other hand, has a higher tensile strength than PLA, making it more resistant to deformation and bending. PLA, while not as strong as ABS or PETG, can still hold up well for many outdoor applications, especially when combined with proper design techniques.

When it comes to weather resistance, PETG is the clear winner. It is known for its ability to resist weathering, including rain, wind, and sun exposure. PLA, on the other hand, can become brittle in cold temperatures and can break down over time in the sun. ABS is also vulnerable to UV damage, which can cause it to become brittle and discolored over time.
Brian Lovett, a small business owner ran an experiment to see whether PET-G or PLA is more weather resistant. He 3D Printed two plant holders and hung them outside in sunny weather. The next day, PLA had melted and lost its stiffness whereas pet-G remained intact, So PET-G is the right material when it comes to extreme weathers.
PETG also has the advantage when it comes to water resistance, making it a great option for outdoor parts that may be exposed to rain or moisture. PLA, while biodegradable, can also degrade over time when exposed to water. ABS is not particularly water-resistant, making it less suitable for outdoor use in wet environments.
Finally, temperature resistance is an important consideration for outdoor applications. ABS has the highest heat resistance, with a melting point around 220-240°C. PETG has a slightly lower melting point, around 230°C, but can still withstand high temperatures better than PLA, which has a melting point around 180-200°C.
Overall, choosing the right filament for your outdoor 3D printing project depends on the specific requirements of your application. It's important to consider factors such as strength, weather resistance, UV resistance, water resistance, and temperature resistance to ensure that your parts will hold up over time.
