PLA vs TPU Filament: Which Is Better for Flexibility?
3D printing is taking the world by storm, and with the introduction of new filaments, 3D printing has become even more versatile. When it comes to flexible prints, PLA and TPU are two of the most popular filaments in the market. But which one should you choose for your next project? In this blog post, we’ll compare PLA and TPU filament in terms of flexibility and help you make an informed decision.
PLA Filament
PLA (Polylactic Acid) filament is the most common filament used in 3D printing. It's a biodegradable thermoplastic made from renewable resources, such as cornstarch, sugarcane, and potatoes. PLA filament is known for its ease of use, low melting point, and smooth surface finish. It's also relatively affordable and widely available.
In terms of flexibility, PLA filament is not the most flexible material out there. While it can be used to make some flexible prints, it's not ideal for projects that require a high degree of flexibility.
TPU Filament
TPU (Thermoplastic Polyurethane) filament is a flexible filament known for its elasticity, durability, and resistance to abrasion. It's a thermoplastic elastomer that's resistant to oils, grease, and solvents. TPU filament is popular in the fashion industry, where it's used to create flexible and comfortable clothing.
In terms of flexibility, TPU filament is far superior to PLA. It can be used to make a wide range of flexible prints, from phone cases and watch bands to shoe soles and automotive parts. TPU filament is also easy to print with, and it adheres well to the print bed.
PLA vs TPU: Which Is Better for Flexibility?
When it comes to flexibility, TPU filament is the clear winner. It's more flexible and elastic than PLA filament, which makes it ideal for projects that require a high degree of flexibility, such as phone cases and watch bands. TPU filament is also more durable and resistant to abrasion than PLA filament, which makes it suitable for projects that require a high degree of wear and tear.
That being said, PLA filament does have some advantages over TPU filament. PLA filament is easier to print with, and it has a lower melting point, which means it requires less heat to print. PLA filament also has a smoother surface finish than TPU filament, which makes it suitable for projects that require a high level of detail.
