When starting your 3D printing journey, one of the first choices you’ll make is selecting the right filament. With so many options available, it’s easy to feel overwhelmed. Two of the most popular materials you’ll encounter are polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS). Both are thermoplastics, meaning they soften when heated and solidify when cooled, but they have key differences. So, which filament is right for your project? Let’s compare them to help you decide.
What Is PLA Filament?
PLA is a bioplastic derived from renewable resources like cornstarch or sugarcane. It is biodegradable under specific industrial composting conditions.
PLA is known for being easy to print with, as it has a lower printing temperature and is less prone to warping. Moreover, it produces a glossy, smooth surface finish, making it a great choice for visual prototypes, decorative items, figurines, and toys.
However, PLA is more brittle than ABS and has a low heat resistance. It can start to deform at temperatures around 60°C.
What Is ABS Filament?
Do you have LEGO bricks at home? Those are made from ABS.
ABS is a petroleum-based plastic known for its durability, strength, and impact resistance. This material is tougher and more flexible than PLA, making it suitable for functional parts that need to withstand stress, such as automotive components, electronic housings, tool parts, and household appliances.
On the other hand, ABS requires higher printing temperatures and a heated print bed to prevent warping as it cools. It also releases a noticeable plastic odor during printing, so good ventilation is a must.
Head-to-Head Comparison
To make the right choice between PLA and ABS filaments for your project, you must consider your specific needs. Are you printing a detailed model where looks matter most? PLA is likely your best bet because of its excellent surface quality and ease of use. Are you creating a functional part that needs to be tough and handle some heat? In that case, ABS would be the superior choice due to its strength and higher temperature resistance.
Find Your Filament
Ultimately, both PLA and ABS are fantastic materials with distinct advantages. Your application, your printer setup, and your experience level will guide you to the right filament.
