Overview
Printing at speed is what this Elegoo Rapid PLA Plus is formulated for, with enhanced fluidity that melts and flows rapidly. It is black filament that the maker says is neatly wound to reduce tangles.
The reason to buy it is the high-speed capability with strength and toughness suited to functional parts. The limitation is the missing temperature settings, which matter most when running a printer fast.
Who it's for
Owners of fast printers who want shorter print times without brittle parts will use the speed headroom. Those who print at ordinary speed and want temperature settings in the listing may prefer a standard spool.
Pros and cons
- Rated for fast printing
- High flexural modulus
- Resists brittleness and cracking
- Neatly wound spool
- Print temperatures not listed
- Speed claim depends on printer ability
Performance notes
Enhanced fluidity lets the filament melt rapidly and flow smoothly, which is what allows high print speeds. High flexural modulus and elongation at break give resistance to brittleness and cracking in functional parts. Tight diameter control supports consistent feeding at speed.
