eSUN Filaments

eSUN is a filament brand whose official site organizes materials into general, aesthetic, engineering, functional, flexible, specialty, and resin sections. The pages verified here cover three PLA-family options: PLA-Basic, PLA+, and PLA-Coffee. Each product page states diameter options, spool weight, colors, applications, and downloadable documents such as TDS, MSDS, RoHS, REACH, and in some cases FDA, EN71, and EU food-contact test files. PLA-Basic is positioned for beginners and cost-conscious printing with fast-printing and easy-printing selling points. PLA+ is described as modified PLA with improved toughness and layer bonding, aimed at functional parts. PLA-Coffee uses recycled coffee grounds, prints with a coffee aroma, and is listed for concept models and rapid prototyping. Use the official pages to confirm current options before ordering.
