SUNLU PLA+ high-speed red filament 1.75mm PLA+ H-S R

The SUNLU PLA+ High-Speed in red is a 1.75 mm filament for FDM 3D printers, designed for users who expect high print quality, smooth operation and shorter printing times. The material is intended to print reliably at high speed while retaining good mechanical properties, making it suitable for everyday projects as well as more demanding models where durability and appearance matter. The spool holds 1000 g of filament, about 330 metres in length.

According to the manufacturer, the filament is wound carefully across the full spool, which supports even feeding and fewer interruptions during printing. Tangles and irregularities are intended to be kept to a minimum. The material is also described as resistant to common printing problems such as nozzle clogging, bubbling, stringing and warping, and it bonds well between layers, which helps dimensional accuracy and durability of finished parts.

The filament is rated at an impact resistance of 8 kJ/m², which the manufacturer states is considerably higher than many standard PLA and PLA+ materials. The vivid red colour adds to the visual appeal of finished models. The filament is listed as compatible with a wide range of FDM printers that support 1.75 mm filament.
