About Esun
Having more than two decades in materials manufacturing, rather than being a newer 3D printing accessory reseller, gives the filament formulations a longer track record of consistent quality than many newer competing brands. Specialty filaments cost more than basic PLA, so a discount code shaves off more dollars on a carbon-fiber-reinforced spool than on a basic PLA spool.
