3D Printer Filaments That Defy UV Rays and Laugh in the Face of Heat

Which filament should you use for outdoor or hot climates? We'll tell you about 3 great options for strong UV and heat resistant prints!

When it comes to 3D printing, enthusiasts and professionals alike are constantly seeking innovative materials that push the boundaries of what can be created. Choosing the right 3D printer filament is key depending on what type of design you’re printing. One critical aspect is the durability of 3D-printed objects, particularly when exposed to challenging conditions such as UV rays and high temperatures. In this article, we’ll delve into the exciting world of UV and heat-resistant 3D printer filaments that are changing the game for additive manufacturing.

  1. PLA+: Sunny Days Ahead

Polylactic Acid, commonly known as PLA, has long been a favorite filament due to its ease of use and eco-friendly nature. However, traditional PLA falls short when it comes to UV resistance. Enter PLA+, an enhanced version that incorporates additives to improve its resistance to ultraviolet rays. PLA+ not only retains the user-friendly characteristics of PLA but also stands strong against the degrading effects of prolonged UV exposure. This makes it an ideal choice for outdoor applications, where sunlight is a constant factor. It doesn’t have the best heat resistance compared to some of the other options out there, so if you’re using this in a hot outdoor climate, keep reading.

  1. PETG: The Heat-Defying Champion

Polyethylene Terephthalate Glycol, or PETG, has gained immense popularity for its versatility and strength. Unlike PLA, PETG boasts an impressive resistance to heat, making it suitable for a wider range of applications. With a glass transition temperature higher than that of PLA, PETG can withstand higher temperatures without deforming. When combined with UV stabilizers, PETG becomes a powerhouse filament that can endure both UV rays and elevated temperatures. This makes it an excellent choice for projects that require resilience in challenging environmental conditions. If your design is for constant high temperature applications like inside a hot car in the middle of summer – read on!

  1. ASA: The Outdoor Enthusiast’s Dream

Acrylonitrile Styrene Acrylate, commonly known as ASA, takes UV and heat resistance to a whole new level. ASA is a weather-resistant filament that excels in outdoor applications. Its chemical composition allows it to maintain its structural integrity even when exposed to harsh sunlight, rain, or extreme temperatures. ASA is often preferred for creating prototypes, signage, and other objects meant for extended outdoor use. Its ability to resist both UV rays and heat ensures that your 3D prints will stand the test of time in various climates.

As 3D printing technology continues to advance, the demand for filaments with enhanced properties becomes more pronounced. The development of UV and heat-resistant filaments like PLA+, PETG, and ASA opens up new possibilities for creating durable and long-lasting 3D prints. Whether you’re crafting prototypes for outdoor use, functional parts for high-temperature environments, or simply looking to extend the lifespan of your creations, these filaments are paving the way for a future where 3D-printed objects can thrive under the harshest conditions. Experimenting with these advanced filaments will undoubtedly lead to groundbreaking applications and push the boundaries of what is achievable in the world of additive manufacturing.
