What to know before buying

Listing details to confirm

The listing claims high-speed suitability, enhanced toughness and low warping, but these are manufacturer claims rather than independently verified results. Customer feedback is mixed on brittleness, bed adhesion and colour accuracy, so these reports may matter for functional parts or colour-matched projects.

Who is it for?

A good fit for

FDM printer owners looking for blue PLA+ filament in a 1 kg spool.
Makers printing functional parts who want to try a PLA formulation promoted for higher toughness.
Users of supported 1.75 mm FDM printers seeking filament described as suitable for high-speed printing.

Less suited to

Buyers who need assured colour matching, bed adhesion or resistance to filament breakage based on the available evidence.
Users of printers that do not accept 1.75 mm filament.

Customer feedback highlights positive experiences with print quality, detail and use across several printers, including the Prusa MK3S+ and Anycubic Vyper. Reports are mixed on bed adhesion, colour accuracy, brittleness and value. For buyers considering functional prints, the reported breakage concerns are relevant despite the listing’s enhanced-toughness claim. The overall rating distribution leans positive but includes a notable lower-rated share, and ratings alone do not establish why people were satisfied or dissatisfied.

Positive themes

Feedback reports clean prints with good detail and generally positive printability and functionality.

Mixed feedback

Some customers report adhesion problems or colour mismatch, while others describe good adhesion and colour accuracy.
Feedback differs on brittleness. Some say it is stronger than ordinary PLA, while others report frequent breaks.
Value opinions are divided, with some finding it worth the price and others considering it overpriced.
