Hey there, 3D printing enthusiasts! Do you often find yourself confused about which filament to use for your project? Well, look no further, because we’re here to compare two of the most commonly used filaments: PETG and Nylon. And with a bit of flare... sorry, we meant flair.
When it comes to choosing a filament for 3D printing, one of the most important factors to consider is moisture resistance. After all, no one wants their 3D print to warp, melt or become brittle due to moisture absorption. Let's put PETG and Nylon to the test and find out which filament is more resistant to moisture.
What is PETG Filament?
PETG (Polyethylene Terephthalate Glycol) filament is a type of plastic that is commonly used for 3D printing. It's a popular choice among 3D printing enthusiasts as it is easy to print and provides good strength, flexibility, and clarity. PETG filament is also widely used in the food and beverage industry due to its FDA approval for food contact.
What is Nylon Filament?
Nylon filaments are known for their strength and toughness. These filaments are more flexible and durable than PETG and are commonly used for printing mechanical parts, gears, and bearings. Nylon filament is also widely used in the textile industry for garments.
Moisture Resistance Comparison
Moisture resistance is an essential factor when it comes to choosing the right filament. Moisture can cause many issues in 3D prints, including warping, cracking, and delamination. Let's compare the two filaments.
PETG Filament Moisture Resistance
PETG has moderate moisture resistance, it absorbs around 0.8% of moisture by weight. However, the amount of moisture it can absorb depends on the quality and the brand of the filament. When compared to other popular filaments like ABS, PETG performs better in resisting moisture.
Nylon Filament Moisture Resistance
Nylon filament is hygroscopic, which means it can absorb moisture from the air. It's a highly moisture-sensitive material and can absorb up to 9% of its weight in water in just 24 hours. The absorbed moisture can cause Nylon to become weak, brittle, and prone to deformation. Nylon filaments require careful handling to prevent moisture absorption.
Conclusion
After comparing the moisture resistance of PETG and Nylon filaments, it is quite clear that PETG has better moisture resistance than Nylon. While Nylon filaments are known for their strength and durability, they are highly sensitive to moisture and require proper storage and handling. In contrast, PETG filaments are easy to handle and provide good moisture resistance. However, it is important to note that the amount of moisture absorption can vary depending on the quality and brand of the filaments.
So there you have it! We hope this comparison has helped you choose the right filament for your next 3D printing project. Remember to take into account the moisture sensitivity and expected use of your 3D print before making your filament selection. Happy printing!
