What to know before buying

Listing details to confirm

The listing consistently identifies red PLA and 1.75 mm filament, but the spool weight is listed as both 1 kg/1000 g and 2.2 Pounds. Treat these as listing details rather than a verified net-filament weight, and confirm the delivered quantity if exact weight matters. The claimed 1.75 mm ±0.02mm appears in the feature copy, while another accuracy statement is shown as +/- 0.02mm. Printer compatibility is not guaranteed, so check filament diameter and spool dimensions against your setup.

Who is it for?

A good fit for

FDM printer owners seeking red PLA filament in a 1.75 mm diameter.
Buyers whose printer stand can accommodate the stated 19.5 cm spool diameter and 5.9 cm width.
Users who want manufacturer-suggested temperature and speed ranges as a print-setting starting point.

Less suited to

Printers requiring a filament diameter other than 1.75 mm.
Buyers who need a confirmed exact net filament weight before ordering.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller spread across lower star categories shows that experiences are not uniform. Without written feedback, the ratings do not identify what buyers liked or disliked. They cannot confirm the claimed diameter tolerance, neat winding or printer compatibility, so treat those as listing claims and check the spool and filament specifications against your own setup.

Frequently asked questions

What filament type and colour is this?

The listing describes Polylactic Acid (PLA) in red, with the colour field given as 1000g-PLA Red.

What diameter is the filament?

The feature text specifies 1.75 mm ±0.02mm. Confirm this suits your printer before buying.

What print settings does SUNLU recommend?

The listing recommends a 200-230°C nozzle, a 50-65°C bed and 50-100mm/s printing speed. These are manufacturer suggestions, not verified settings for every printer.

How much filament is on the spool?

The listing describes a 1 kg spool and 1000.0 gram, while the weight field says 2.2 Pounds. The net-filament weight is therefore not presented consistently.
