PLA (Polylactic Acid) is a popular material used in 3D printing. There are several types of PLA available, including Standard PLA and PLA Professional (or PLA+). Each type has its own set of characteristics, making them suitable for different applications. Here are some advantages of PLA Professional compared to Standard PLA:

1. Improved Mechanical Properties: PLA Professional generally has better mechanical properties than standard PLA. This includes higher tensile strength, impact resistance, and durability. These improvements make PLA Professional more suitable for functional parts that need to withstand more stress.
2. Better Thermal Resistance: PLA Professional can withstand higher temperatures compared to standard PLA before it starts to deform. This makes it more suitable for applications where the printed parts might be exposed to higher temperatures.
3. Enhanced Print Quality: PLA Professional often provides a smoother finish with more consistent color and fewer printing defects like stringing or warping. This results in aesthetically pleasing prints with a more professional look.
4. Less Brittle: Standard PLA is known for being somewhat brittle, which can be a drawback for certain applications. PLA Professional is typically less brittle, which reduces the risk of the print breaking or cracking under stress.
5. Better Layer Adhesion: The improved formulation of PLA Professional can lead to better layer adhesion, resulting in stronger prints. This is crucial for large prints or prints with thin walls.
6. Wide Range of Applications: Due to its improved properties, PLA Professional can be used for a wider range of applications, including those that require more durable and resilient parts.
7. Ease of Printing: Like standard PLA, PLA Professional is easy to print with and doesn’t require a heated bed or closed printing chamber, making it accessible for hobbyists and professionals alike.
8. Environmental Impact: Both types of PLA are biodegradable under industrial composting conditions. However, PLA Professional might have a slightly different environmental impact due to its additives and manufacturing process.

It’s important to note that the exact properties of PLA Professional can vary between manufacturers. Therefore, it’s advisable to check the specific product details or data sheets provided by the manufacturer for the most accurate information.
