3D printer filament designed for high-speed, reliable prints, improving toughness and dimensional control. For makers and small workshops who need faster turnaround and fewer failed runs, SUNLU PLA Plus Filament aims to deliver stronger, smoother parts straight from the spool. Is this the right filament for a high-speed setup?
⚡ At a Glance
- • Print Performance: Optimised melt flow for high-speed printing up to 600mm/s with reduced stringing
- • Best for: Enthusiasts and professionals using high-speed printers who need durable PLA parts
- • Not ideal for: Applications that require very flexible filaments or specialised engineering plastics
Upgraded PLA+2.0 increases toughness while maintaining tight dimensional control. Vacuum-sealed spools with removable cores simplify handling and reduce moisture-related print issues.
Faster prints with reliable extrusion – With optimised melt flow for high-speed printing
Melt flow has been tuned to support high feed rates and reduce stringing, allowing successful extrusion across a broad speed range up to 600mm/s. Compatibility with high-speed machines such as the Bambu Lab X1 series helps avoid common high-speed issues like clogging.
Shorter print times and consistent layer quality for large or numerous parts, saving production time and reducing the number of failed prints.
Stronger, less brittle parts – Thanks to PLA+2.0 formulation with higher toughness
The PLA+2.0 formulation delivers a measured increase in toughness, cited as 12x higher than standard PLA, which improves impact resistance and part durability. Dimensional stability is supported by precise filament diameter control.
Parts withstand handling and light mechanical stress better, making the filament suitable for functional prototypes and end-use components that need greater robustness.
Ready-to-print spools and moisture control – With vacuum-sealed packaging and a removable core
Each spool is vacuum-sealed and shipped with a desiccant pack to minimise moisture absorption. The removable inner core design matches Bambu-style refill systems to allow direct swapping without respooling.
Dry, easy-to-load filament reduces setup fuss and the chance of moisture-related print defects, so printers can be up and running sooner.
✨ The 4 Key Reasons for SUNLU PLA Plus Filament
- Diameter Consistency – Ensures consistent layer accuracy and reduces failed prints.
- High-Toughness Formula – Produces stronger parts that withstand handling and stress.
- Vacuum-Sealed Spool – Prevents moisture uptake for reliable extrusion after storage.
- Removable Spool Core – Enables direct refill with Bambu-compatible cores, no respooling.
