3D printing has revolutionized the way we create objects, from the way we create custom parts to the way we produce prototypes. With the help of 3D printing, we can now quickly and easily create objects with complex geometries and intricate details. But in order to get the best results, it’s important to choose the right material for your 3D printing project. When it comes to 3D printing materials, two of the most popular options are PLA and ABS. So, which one is best for 3D printing?
Material Properties
PLA and ABS are two of the most popular materials used in 3D printing. PLA is a biodegradable thermoplastic made from renewable resources such as cornstarch or sugarcane. It’s easy to use, has good dimensional stability, and doesn’t require a heated bed. ABS, on the other hand, is a petroleum-based thermoplastic that’s more heat-resistant and durable than PLA. Additionally, ABS is stronger and more flexible than PLA, making it ideal for parts that need to be more durable.
Printability
PLA is generally considered to be easier to print than ABS due to its lower melting temperature and lack of warping. Additionally, PLA doesn’t require a heated bed, making it ideal for users who don’t have access to a heated build platform. ABS, on the other hand, requires a heated bed and can warp if not printed correctly.
Applications
PLA is a great material for printing prototypes and parts that don’t need to be highly durable. It’s also a good choice for printing items that will be used indoors, as it’s not as heat-resistant as ABS. ABS is a better choice for parts that need to be strong and durable, as it’s much more heat-resistant and impact-resistant than PLA. Additionally, ABS is more flexible than PLA, making it a great choice for parts that need to bend or flex.
Cost
PLA is generally cheaper than ABS, making it the more affordable option for 3D printing projects. Additionally, PLA is often sold in larger spools, which can help reduce the cost per gram of material. ABS, on the other hand, is usually sold in smaller spools, making it more expensive than PLA.
Conclusion
When it comes to 3D printing materials, PLA and ABS are two of the most popular options. PLA is a biodegradable thermoplastic that’s easy to use and doesn’t require a heated bed. ABS is a petroleum-based thermoplastic that’s more heat-resistant and durable than PLA, making it ideal for parts that need to be strong and durable. PLA is generally cheaper than ABS, making it the more affordable option for 3D printing projects. Ultimately, the best material for your 3D printing project depends on your application and budget.
