High Speed PLA: Mastering the Art of Fast Printing

In the dynamic world of 3D printing, speed often correlates with efficiency. High Speed PLA, such as MH Build Series PLA-HS, is revolutionizing the way we approach printing, especially for those venturing into the realms of 150 to 200 mm/s speeds. This guide by MatterHackers will dive into the intricacies of High Speed PLA, comparing it with traditional PLA and providing tips to harness its full potential.

What is High Speed PLA?

MH Build Series PLA-HS, or High-Speed PLA, is a game-changer in the PLA filament market, designed specifically for rapid printing without sacrificing quality. Key features include:

• Enhanced Extrusion Efficiency: Tailored for fast printing, ensuring smooth and rapid filament flow.
• Ease of Printing: Retains the user-friendly characteristics of regular PLA.
• Optimized Rheology: Quick transition from fluid to solid, thanks to its modified Melt Flow Index (MFI), making it ideal for fast printing.
• Compatibility: Works exceptionally well with high-speed printers like Bambu Lab 3D Printers.

Understanding Melt Flow Index (MFI)

Melt Flow Index is crucial in differentiating High Speed PLA from its regular counterpart:

• Definition: MFI measures the flow rate of melted plastic, indicating how easily a material can be extruded.
• Relevance to High Speed PLA: A higher MFI in High Speed PLA facilitates faster, smoother extrusion, and quicker cooling - essential for maintaining quality at high printing speeds.

High Speed PLA vs. Regular PLA: A Comparative Analysis

Print Quality:

High Speed PLA:

• Excels at speeds up to 350 mm/s with superior surface quality and detail.
• Enhanced interlayer bonding, ensuring strong and reliable prints.

Generic PLA:

• Suitable for moderate speeds with good quality but less detailed at high speeds.
• Weaker interlayer bonding when printed fast, leading to potentially weaker prints.

Mechanical Properties:

High Speed PLA:

• Demonstrates superior mechanical strength and impact resistance, suitable for functional parts.

Generic PLA:

• Adequate for decorative items but less effective under stress, especially in thinner structures.

Surface Finish:

High Speed PLA:

• Consistent, refined finish across all speeds, enhancing aesthetic appeal.

Generic PLA:

• Glossy at lower speeds, but can become matte at higher speeds.

Why Choose High Speed PLA for Fast Printing?

With virtually no downsides at everyday printing speeds, High Speed PLA is an excellent choice for those aiming for efficiency. It retains its quality and characteristics even at lower speeds, though retraction settings may need fine-tuning.

Conclusion: 

High Speed PLA, like MH Build Series High Speed PLA, represents a significant advancement in 3D printing materials. It bridges the gap between speed and quality, making it an ideal choice for both rapid prototyping and functional part production. By understanding its properties and fine-tuning your printer settings, you can unlock a new level of printing efficiency.
