What is high-speed filament & do you really need it?

In the rapidly growing world of 3D printing, speed is becoming increasingly important. Whether you are a hobbyist, a maker, or a professional – if you want to optimize your workflow, you have surely come across high-speed filament. But what exactly is it, and is the switch worth it? In this article, we will explain everything you need to know about high-speed filament, its advantages, and whether it really makes sense for you. We will also introduce you to the best products in the SUNLU high-speed series – a brand known for affordable, reliable, and high-quality 3D printing filaments.

Whether for prototypes, functional parts, or creative designs: with the right knowledge about high-speed filament, you can print significantly faster – without sacrificing quality. Let’s get started!

What is high-speed filament?

High-speed filament (also called hyper-speed or HS-PLA) is a specially developed 3D printing material optimized for extremely high extrusion speeds in modern FFF/FDM printers. Unlike conventional PLA, PETG, or ABS, which often exhibit issues like stringing, under-extrusion, or poor layer adhesion at speeds above 100 mm/s, high-speed filament features a higher melt flow index (MFI) and improved thermal properties.

Thanks to special additives, it melts faster, flows more evenly through the nozzle, and cools down more quickly – even at 300–600 mm/s, prints remain clean and precise. Many variants offer up to 500% better material flow compared to standard PLA.

The most common types are high-speed PLA, PLA+, and some PETG blends. They work excellently with high-speed printers like the Bambu Lab X1/P1, Creality K1/K1 Max, Anycubic Kobra 3, or similar models.

In short: High-speed filament is not just a marketing gimmick, but a genuine material development for the demands of today's ultra-fast printers.

The advantages of high-speed filament

Switching to high-speed filament brings noticeable improvements:

  • Significantly shorter print times – up to 300–600 mm/s possible; the total duration is often halved compared to standard filament.
  • High quality despite speed – excellent layer adhesion, less warping, smoother surfaces, and better overhangs.
  • Efficient flow & cooling – up to 180% better heat dissipation, hardly any clogs, and consistent material flow.
  • Broad compatibility – works on standard printers too (just slower) and is ideal for high-speed models.
  • Economical for high volume – Slightly more expensive per roll, but offers enormous time savings for regular printing.

Many users report "flawless prints" with high impact resistance – perfect for functional components.

Do you really need high-speed filament?

Not everyone needs it – it depends on your printer and your goals:

  • For high-speed printers (Bambu Lab, Creality K-series, etc.): Yes, absolutely! Standard filaments hold the hardware back. High-speed material unlocks the full potential.
  • For time-critical projects – prototyping, small batches, events, or frequent printing: the time saved is enormous.
  • On a small budget or with slow printers – standard PLA is often sufficient. However, high-speed filament performs better than standard PLA even at 80–150 mm/s.
  • When not to use it – For highly detailed miniatures, jewelry, or prints in hot, enclosed chambers, a lower melting point can be a disadvantage.

Conclusion: If speed is important to you and you want clean results, high-speed filament is a worthwhile investment – and not just a "marketing gag."

You can find the products in the official SUNLU shop, on Amazon, or at 3DJake. Bundles with multiple colors often offer the best prices.

How to choose the right high-speed filament

These points will help you in your selection:

  1. Printer compatibility – All-metal hotend recommended for high flow rates.
  2. Material type – PLA for simplicity, PLA+ for more robustness.
  3. Desired speed – Test at lower values first, then increase.
  4. Brand quality – SUNLU offers top quality at fair prices.
  5. Budget – SUNLU combines premium features with affordable costs.

Tip: Calibrate your printer (e.g., using OrcaSlicer's volumetric speed test) for the best results.

Conclusion: Print faster with high-speed filament

High-speed filament is not a passing trend, but a useful advancement for more efficient 3D printing. When time and quality count, it is definitely worth it – especially with brands like SUNLU that offer strong performance at affordable prices.
