SUNLU PLA+ Magenta 1.75 mm 1 kg filament 🎧

This PLA Plus filament 1.75mm spool brings tougher properties than standard PLA while keeping the ease of printing associated with bio-based plastics. It is intended for users who want higher toughness and consistent extrusion for hobby prints, prototypes and functional parts, and it reduces the risk of brittle failures during handling. The colour is magenta and the spool weighs 1 kg, making it convenient for repeated prints.

Key Points

SUNLU PLA+ improves on ordinary PLA by offering greater hardness and improved interlayer adhesion, which helps produce sturdier prints and fewer breakages during post-processing. The filament is claimed by the manufacturer to have no bubbles or impurities, resulting in smoother feed and reduced nozzle clogs. The spool is wound using a care technique designed to prevent tangles, which lowers the chance of print interruptions and makes long jobs more reliable. 🎨

This material has low shrinkage compared with some other thermoplastics, so dimensional stability is better for multi-part assemblies. It is also vacuum packed to preserve dryness during storage and shipping, according to the manufacturer. Do note that, as with most PLA blends, it remains less heat resistant than engineering plastics and may soften at elevated temperatures during long exposure.

Practical Tips

Start prints at a nozzle temperature recommended by the printer manufacturer and adjust in small increments if layer adhesion needs improvement. A heated bed is not mandatory for PLA+ but setting a mild bed temperature can reduce warping on larger parts. For fine detail, slow the print speed slightly to improve surface finish and to take advantage of the filament's claimed roundness and tight tolerance. 🛠️

If you store the spool for long periods, keep it sealed with desiccant to avoid moisture uptake that can cause bubbling or stringing during extrusion. For post-processing, the filament sands and paints similarly to standard PLA, though the increased toughness may require slightly more aggressive sanding for a smooth result. Consider that the manufacturer’s claims of no clogs and no bubbles are based on ideal conditions; results can vary with printer setup and environmental humidity. 🔧
