ELEGOO Rapid PLA Plus 1.75mm Green 1kg (PLA+ filament) for fast 3D printing
Product description
What it is (and why people buy PLA+ in the first place)
ELEGOO’s Rapid PLA Plus filament is a 1.75mm PLA+ material aimed at faster printing and better real-world toughness than standard PLA. In plain terms, it’s for when you want “quick, solid prints” rather than a fragile result that can chip if you handle it or if the part is slightly stressed.
PLA+ sits in an interesting middle ground. Compared with basic PLA, it’s positioned as having higher impact strength and reduced brittleness, which is handy for things like functional prototypes, brackets, casings, or any model that needs to survive being bumped rather than just being purely decorative. This spool is sold as 1kg on a cardboard spool, so it’s also the sort of purchase you make when you expect to print regularly.
That said, “fast” depends a lot on your printer setup and how consistently your machine feeds filament. The filament can be designed for high-speed use, but you’ll still want to confirm your machine behaves well at those speeds.
The essentials: what stands out
The two most noticeable claims here are speed and consistency. On paper, the filament is designed for up to 600 mm/s printing speed, helped by enhanced fluidity—so it melts rapidly and flows smoothly. If you’ve ever spent too long waiting for a print to finish, a filament marketed for high-speed throughput can be a practical way to shorten project turnaround.
The other big selling point is dimensional accuracy and winding quality. ELEGOO states a diameter accuracy of +/- 0.02 mm, with strict tolerances meant to support smooth and consistent feeding. It also mentions full mechanical winding and manual inspection to reduce tangles, snaps and breakage—issues that can be especially annoying when you’re pushing speed.
How it behaves in day-to-day printing
If you’re planning a batch print—say you’re producing multiple identical parts for a small workshop project—this kind of “rapid” PLA+ concept makes sense. The idea is that smoother feeding and better flow should translate into fewer interruptions, more consistent layers, and less fuss.
One practical micro-scenario: imagine printing a set of brackets or spacers that you’ll fit later. With PLA+, you’re aiming for fewer “hairline chips” after handling. You’re not necessarily expecting engineering-grade performance, but you are trying to avoid that classic PLA brittleness where a part cracks too easily.
However, you should temper expectations if you’re printing something that needs high strength under heavy load or extreme temperatures. The input information focuses on impact strength and toughness versus regular PLA, not on any specialised performance claims beyond that.
Strength, toughness and accuracy—what you can reasonably expect
ELEGOO describes Rapid PLA+ as having higher impact strength than regular PLA, making it more resistant to brittleness and cracking. For buyers, that’s the part that matters most if your prints are more than display pieces.
Then there’s accuracy: the filament is described as 1.75mm diameter with +/- 0.02 mm dimensional accuracy. In practice, consistent diameter is one of the big reasons to hope for steady extrusion—because if the filament varies a lot, you can get inconsistent flow and feeding issues.
Still, it’s not perfect by default. Even with good tolerances, real results depend on your hotend, nozzle, fan settings, and how well your printer’s firmware handles fast printing. If your machine is on the less stable side, you may see quality drop when you try to chase speed.
Less tangles and smoother handling (the underrated quality)
High-speed PLA plus is only useful if it’s manageable. ELEGOO specifically claims full mechanical winding and strict manual inspection, with an aim to reduce tangles, snaps and breakage. That’s a big “silent” feature: when filament is neatly wound and behaves consistently, you’re less likely to lose time mid-print to tangles or a line snapping.
If you’ve had filament curl on the spool or feed unevenly, you’ll recognise why this matters. It won’t replace good machine setup, but it can remove one source of frustration.
Where it fits best (and where it may not)
It’s pitched as compatible with both regular printers and high-speed printers. The input also gives examples of high-speed series it’s intended for, including Neptune 4 series, K1 series, Ender 3 series, Kobra series, Adventurer series and more.
It’s a solid match if you: - want speed-friendly PLA+ rather than slow, purely aesthetic PLA - care about impact resistance (less brittleness and cracking than standard PLA) - value consistent feeding, with a diameter tolerance stated at +/- 0.02 mm - prefer buying a full 1kg spool for repeat jobs
It may not be the best choice if you’re: - prioritising maximum temperature/engineering performance (nothing here claims that) - running a printer setup that struggles to maintain stable extrusion at high speed - expecting “drop-in excellence” regardless of tuning—fast profiles can highlight weaknesses in your setup

Buying verdict
Is it worth it?
Worth considering if you want a PLA+ filament that’s designed around fast printing (up to 600 mm/s) and you care about better toughness than standard PLA. The stated dimensional accuracy and the focus on winding quality are the sort of details that can make prints feel more predictable, especially when you’re pushing speed.
You may want to skip it if you don’t plan to print at higher speeds or if your printer is not tuned for smooth feeding and consistent extrusion—because chasing throughput can expose setup issues. It’s not positioned as a specialist, extreme-performance filament, it’s more a practical “speed + improved toughness” option for everyday makers.
Mini FAQ
Is it suitable for high-speed printers?
It’s described as fitting both regular printers and high speed printers, with specific high-speed series mentioned in the provided information.
How fast can you print with it?
The input claims up to 600 mm/s printing speed, enabled by enhanced fluidity for rapid melting and smooth flow.
Is PLA+ stronger than standard PLA?
According to the provided description, it has higher impact strength than regular PLA and is more resistant to brittleness and cracking.
Does the filament come on a spool?
Yes—this version is listed as a 1kg filament on a cardboard spool.
What matters most before you buy?
Check that your printer setup supports consistent feeding when you run faster print profiles, and keep expectations realistic: the aim is toughness versus regular PLA, not a guarantee of engineering-grade performance.
