1 / 7SUNLU PLA+ 2.0 Grey 3D Printer Filament, 4 kg
SUNLU PLA+ 2.0 is a four-spool grey filament bundle for compatible 3D printers. Its 1.75 mm format and manufacturer-claimed high-speed printing range make it a fit for users who want a larger stock of one colour, though customer feedback reports both good printing and clogging or feed interruptions.

Pros and cons
Pros
- Four spools in the same colour suit longer print runs or repeat projects without changing colour.
- The stated 1.75 mm diameter suits printers that accept that filament size.
- The detachable spool core may simplify refill handling on compatible systems.
Cons
- The bundle is limited to grey, so it does not provide colour variety.

What to know before buying
Listing details to confirm
The listing's technical details give 30-600mm/s, while feature copy gives 50-600mm/s. The title, spool model and four-pack details indicate four 1 kg spools, but the listed total weight is 4 Kilograms. Treat these as listing claims and confirm the selected variant and speed guidance before buying. Customer reports include clogging and printer stoppages, so the high-speed claims should not be read as a guarantee of uninterrupted printing.
Who is it for?
A good fit for
- Users with a compatible 1.75 mm printer who regularly print in grey.
- Owners of supported high-speed printers seeking a bulk PLA+ supply.
- Bambu-system users interested in the claimed detachable-core refill design.
Less suited to
- Buyers who need multiple colours in one bundle.
- Users whose printer does not accept 1.75 mm filament.

Customer feedback describes good print quality, including a report of use with a Bambu Lab A1, but experiences with quality and reliability are mixed. Some find the filament reliable, while others report nozzle clogging or the filament stopping the printer. Those concerns matter particularly for long or fast prints, so the claimed high-speed capability should be weighed against reports of feed interruptions. The aggregate ratings lean positive overall, but do not establish consistent results for every printer or spool.
Positive themes
- Some customers report good printing and positive print quality.
Negative themes
- Some customers report nozzle clogging and the filament stopping the printer.
Mixed feedback
- Feedback on overall quality and reliability is mixed.
