The Best 3D Printing Filament for Outdoor Use
Explore our guide on the best filament options for outdoor 3D printing, featuring materials that can withstand extreme temperatures and UV-resistance for optimal results.
Find your next favorite filament to use for outdoor projects that will be exposed to volatile conditions and temperatures below!
It's important to note that this ranking is based on general industry knowledge and can vary depending on the specific formulation and manufacturing process of each material. Additionally, other factors such as thickness, color, and surface finish can also affect the UV resistance of a material.
- ASA filament has high UV resistance, meaning it won't degrade or discolor when exposed to sunlight.
- It's dimensionally stable, meaning it won't warp or shrink when exposed to extreme temperatures.
- ASA is also resistant to moisture, meaning it won't be affected by rain or other water sources.
- ASA filament is highly durable and can withstand impacts and wear.
ASA 3D printing filament is the #1 choice for outdoor use - it is known for its good UV resistance. Compared to other types of plastic such as ABS or PETG, ASA is more resistant to the effects of UV light and has a higher resistance to color fading, warping and cracking.
Recommended 3D printer settings for ASA filament:
- Extruder Temp: 240±10 °C
- Bed Temp: 95±10 °C

- Polycarbonate filament is highly durable and resistant to harsh weather conditions.
- It has excellent UV resistance and is resistant to discoloration.
- It is lightweight and has good impact resistance.
- It has a high melting point and is heat and chemical resistant.
Polycarbonate filament is an excellent choice for use outside - it contains UV stabilizers that prevent degradation from exposure to UV light. Additionally, it has a high melting temperature, making it suitable for use in high-heat environments.
Recommended 3D printer settings for Polycarbonate filament:
- Extruder Temp: 290±20 °C
- Bed Temp: 130±15 °C

- Nylon filament has good flexibility and impact resistance, so it's great for parts subject to stress and wear.
- It's water resistant, which is important for outdoor objects that may be exposed to the elements.
- Nylon has a high melting temperature, which makes it suitable for use in high-heat environments.
Nylon filament is known for its strength, durability, and resistance to wear and abrasion. Nylon is also UV resistant to some degree, but prolonged exposure to UV light can cause it to degrade over time and even make parts slightly brittle. It can also change color and become yellowish due to UV exposure.
Recommended 3D printer settings for Nylon Filament:
- Extruder Temp: 255±15 °C
- Bed Temp: 70±10 °C

- TPU filament is lightweight yet durable
- TPU can handle being exposed to moisture.
- Since it's flexible, it can withstand impacts and other stresses while being used outdoors - great for outdoor gasket replacements.
TPU filament is a great choice for outdoor use if ASA and Polycarbonate are not an option and you need flexibility for your project. However, TPU is not known for its UV resistance. Prolonged exposure to UV light can cause TPU to degrade over time and become brittle, discolored and lose its physical properties. It is not recommended to use TPU in applications that will be exposed to UV light for extended periods of time. TPU is also resistant to oils, chemicals, and weathering.
Recommended 3D printer settings for TPU filament:
- Extruder Temp: 250±10 °C
- Bed Temp: 50±10 °C

- PETG filament is highly durable and impact-resistant, making it great for outdoor applications that may take a beating.
- PETG has excellent flexibility, meaning it can withstand extreme temperatures without warping or cracking.
- PETG is a relatively affordable 3D printing material that is readily available, so you won’t have to break the bank for your outdoor projects.
PETG filament is UV resistant to some degree, but prolonged exposure to UV light can cause it to degrade over time. It is not as UV resistant as some other plastics such as ASA or polycarbonate.
Recommended 3D printer settings for PETG filament:
- Extruder Temp: 245±10 °C
- Bed Temp: 60±10 °C
