Beschreibung
Print speed is a material property, not a printer setting. A machine rated for 600mm/s will sit at 100mm/s all day if the filament cannot melt and set fast enough to keep up, and no amount of slicer tuning fixes that.
RAPID PLA+ is ELEGOO answering that constraint directly. The formulation is tuned for flow: it melts cleanly at high volumetric rates, bonds to the layer beneath it while still hot, and skims over at the nozzle so you can push speeds that ordinary PLA turns into stringing and weak walls. It is PLA at its core, so it still prints without an enclosure and still smells like nothing in a home office, but it behaves better under load than the standard blend because the impact modifiers are already in the pellet.
Sizes run from a single one-kilogram spool to ten-kilogram multi-spool packs, in black, white, grey, red, blue, green, yellow, orange, silvery, beige, and brown, plus mixed colour kits for anyone printing a full model in one pass. Everything sits on a 1.75mm diameter with tight roundness tolerance, which is what keeps extrusion consistent on a direct-drive machine running at the top of its speed range.
Spool it right and the printer finally runs the way the spec sheet promised.
Why It Belongs In Your Kit
- ✦ Rated for print speeds from 30mm/s up to 600mm/s, so the material stops being the bottleneck
- ✦ PLA+ blend with impact modifiers already compounded in, giving tougher parts than standard PLA
- ✦ Tight 1.75mm roundness tolerance keeps extrusion steady on direct-drive and Bowden setups alike
- ✦ Sizes from a single 1kg spool to 10kg multi-spool packs, plus mixed colour kits for full models
- ✦ Available in black, white, grey, red, blue, green, yellow, orange, silvery, beige and brown
- ✦ Compatible with most FDM printers and works without an enclosure in a normal home or workshop

What It Is Good For
Functional parts first: brackets, jigs, enclosures, and print-farm runs where the machine is paid by the hour and downtime is the real cost. The 600mm/s ceiling matters most on batch work, where the same small part is printed dozens of times and a 20 percent speed gain compounds across a shift. Buy the 1kg spool to test a profile, then move to the 3kg and 5kg sizes once the machine is dialled in and the colour is settled.
Questions, Answered
Q: Does this actually print at 600mm/s on any printer?
A: No, and no filament does. The material is formulated to hold up at high flow rates, so it will not be the limiting factor. Your hotend, nozzle diameter, and part cooling decide the real ceiling, and most direct-drive machines will find their limit around 200 to 300mm/s.
Q: What is the difference between RAPID PLA+ and regular ELEGOO PLA?
A: The plus is in impact resistance and flow behaviour. RAPID is compounded with modifiers that make parts less brittle and is tuned for fast melting, which matters most on large or high-speed prints where standard PLA tends to under-extrude.
Q: Do I need an enclosure to print it?
A: No. It is PLA-based, so it prints at PLA temperatures and does not need a heated chamber. An enclosure helps on very large parts by keeping the ambient air steady, but it is not a requirement.
Q: Will it fit a stock Creality, Bambu, or Prusa machine?
A: It is a 1.75mm filament on a standard spool, and it is listed as compatible with most FDM printers. Spool holders on wider-diameter machines may need an adapter ring, which is worth checking before ordering a 10kg pack.
Q: Which colour should I order first?
A: Black or white if you are dialling in a new profile, because defects are easiest to read against those two. Move to colour once the print is clean, and use the mixed kits when a multi-part model needs to be printed in one session.
Q: How should the spool be stored?
A: Sealed with the desiccant it arrives with. PLA absorbs moisture slowly, and a damp spool is the usual suspect when stringing appears on a profile that used to print cleanly. Dry it at 45C for four to six hours if it has been open for more than a few weeks.
