Pros and cons

Pros

A four-kilogram supply in a single colour can suit repeat prints or projects that use a lot of black filament.
The 1.75 mm diameter is a commonly used size, and the listing claims compatibility with most 1.75 mm FDM printers.
Customer feedback describes the finish and print quality positively, while several users raise practical concerns covered below.

Cons

Some customer feedback raises concerns about stringing and filament binding on the spool, so results may require attention to spool handling and print settings.

What to know before buying

Listing details to confirm

The listing gives two different dimensional accuracy figures, +/- 0.03mm and +/- 0.02mm. Its surface-finish description also conflicts, calling the filament matte and non-glossy in one place but glossy in another. It says 100% wound neatly while the review summary reports some spool binding. Check the selected listing for the applicable tolerance and finish claims. The suggested temperatures and speed are recommendations, not guaranteed settings for every printer.

Who is it for?

A good fit for

FDM printer owners whose machine accepts 1.75 mm PLA and who want four black 1 kg spools.
Makers producing larger or repeated black parts who prefer a matte-looking finish, subject to confirming the finish and tolerance details.

Less suited to

People who need multiple colours in the bundle.
Buyers whose printer does not accept 1.75 mm PLA or who need guaranteed print results without tuning.

Customer feedback is generally favourable about print quality, reliability and the matte appearance, with reported smooth printing and perceived value. However, feedback is mixed on bed adhesion and spooling, including reports of filament binding, and stringing is also raised. These practical reports matter for a four-spool bundle intended for repeat printing, but they do not establish that every spool or printer will behave the same way.

Positive themes

Customers report good print quality and a matte finish.
Feedback describes reliable printing and value positively.

Negative themes

Stringing is a reported concern in customer feedback.

Mixed feedback

Feedback on adhesion and spooling is mixed, including both positive adhesion experiences and reports of filament binding against itself on the spool.

Frequently asked questions

How much filament is listed in this bundle?

The listing gives a total weight of 4 Kilograms and claims four 1 kg spools. It describes the colour as black across all four.

Will it fit my 3D printer?

The stated diameter is 1.75 Millimetres and the listing describes it for FDM printers. Confirm your printer uses 1.75 mm filament and check its settings before printing.

What print settings does SUNLU recommend?

The listing recommends a nozzle temperature of 200-230°C, a bed temperature of 50-65°C and a print speed of 50-100mm/s. These are starting recommendations, not universal settings.

Is the finish definitely matte?

The listing describes a matte finish but elsewhere says the printed surface is glossy. Treat the finish description as inconsistent and check before buying if appearance is important.
