3D printing filament designed for tougher, more reliable prints, SUNLU PLA Plus Filament targets makers who want fewer failed jobs. Print with greater confidence when producing functional parts or prototypes thanks to neater spooling and pre-drying. Is the increased toughness and careful packaging a sensible upgrade for regular FDM work?
⚡ At a Glance
- • Dimensional Accuracy: Consistent diameter control with tolerance of +/- 0.02mm for predictable extrusion
- • Best for: Hobbyists and makers needing tougher PLA prints and dependable spool feeding
- • Not ideal for: Projects that require flexible filament types or high-temperature engineering plastics
Toughness Enhanced PLA PLUS increases impact resistance compared with standard PLA. Neat machine winding and vacuum sealing reduce feed issues and moisture.
Strong Functional Parts – Thanks to Toughness Enhanced PLA PLUS
Toughness Enhanced PLA PLUS increases impact resistance, with manufacturer claims of more than 11 times the toughness of regular PLA. The formulation aims to reduce brittleness while retaining PLA printing characteristics.
Printed parts resist cracking and handle light mechanical stress better, making them suitable for clips, housings and small functional prototypes.
Fewer Print Failures – With Neatly Wound Spools and Clog-Free Processing
Machine-controlled winding aligns filament neatly on the spool, and full mechanical winding with multiple quality inspections minimises snags and bubbles. Filament is checked before packaging to reduce feed interruptions.
Spools feed smoothly through extruders, cutting downtime on long prints and lowering the risk of failed jobs due to tangles or bubbles.
Consistent Dimensions – Thanks to +/- 0.02mm Diameter Control and Drying
Strict production controls maintain diameter tolerance at +/- 0.02mm, and filaments undergo a 24-hour drying cycle followed by vacuum sealing to limit moisture. These steps help preserve dimensional stability during storage.
Layer adhesion and dimensional repeatability improve, so parts are more predictable across multiple prints without constant re-tuning.
