Black flex filament 1.75 in a 300 g (100 m) spool is usually picked for smaller, focused prints where flexibility is part of the design. It’s not about volume here — it’s about control.
Flexible filament behaves differently from rigid plastics, and that difference becomes obvious almost immediately.
With black flex filament 1.75, printed parts don’t stay rigid after cooling. They bend, compress, and return to shape.
In practice, flex filament black is often used for protective elements, covers, or parts that need to absorb small impacts.
Flexible materials require a bit more attention at the start, but once that’s done, flex filament 1.75 tends to behave in a predictable way.
The flow stabilizes, layers build evenly, and the print holds together without sudden inconsistencies.
A 300 g spool works well when you’re printing specific components or testing designs. It allows you to move between materials without building up unused filament.
Even at this size, flex filament 1.75 maintains consistent output.
Black flex filament is often chosen for functional parts, but the visual side still matters. Black gives a neutral, uniform look that works across different types of prints.
It also helps mask minor surface variations that can appear with flexible materials.
Black flex filament is used when parts need to move, compress, or handle repeated stress.
Black flex filament 1.75 in a 300 g (100 m) spool is easy to integrate into smaller projects or iterative work.
FLEX filament is used for printing protective flexible elements for machine and mechanism units, as well as oil seals and other types of sealing elements. Naturally, it is also used for prototyping rubber products. Also, any damper and vibration protection elements are printed from FLEX. Given its properties, the filament can be used to print any product, the application of which requires such a property as flexibility. For example, elements of footwear and automotive parts.
The flexibility of FLEX plastic requires a special approach when printing.
First, it is not fast plastic. It needs to need print slowly - do not set the filament feed faster than 30 mm / s.
Secondly, if you have a bowden feed printer, it will be much more difficult to print than with a direct feed. Judging by the feedback from our customers, printing on bowden is possible, but we recommend direct feeding, which will help to avoid difficulties in work.
Third, follow the recommendations for temperature and speed, carefully adapting them to your results, because the FLEX filament is easily deformed in the nozzle. In general, we recommend using a separate nozzle for this filament - the remnants of old filaments of other types can greatly complicate the process.
Fourth, FLEX absorbs moisture well, so it is important to observe safe storage conditions. In this case, when printing, it is better to ensure that the filament moves freely without any resistance, so that the feed mechanism does not apply force and start to “pull” the material, which can cause stretching or bending.
