Spool-Free Packaging

Even for novice printers who don’t use that much material, A no-spool design is more environmentally friendly. Non-biodegradable leftover spools are tossed aside into landfills and other waste dumps.

Universally Accepted

Echo3 PLA filament is considered to be one of the easiest and most widely used PLA filaments. It is suitable for both 3D printing beginners and professionals. Echo3 PLA also does not require a heated bed, opening use up to a wider range of makers and tinkerers.

Excellent Printing Performance

Echo3 uses a proprietary formula to improve its rigidity, strength and printing performance. Compared with regular PLA, Echo3 PLA filament is several times stronger and has a smoother finish. This means less down time and more prints completed.

Renewable Material
