eSUN is one of the most widely available FDM filament brands in the world, a Chinese manufacturer founded in 2002 in Shenzhen. With an annual output of over 15,000 tons of filament, eSUN is among the largest producers of 3D printing materials globally. Their position is 'budget price with acceptable quality', €15-€25/kg for standard filaments, about half the price of Polymaker or Prusament. For hobbyists, beginners, and production farms with high volume, eSUN is the most economically sensible choice. For dental, medical, or certified engineering work, pick premium brands.
eSUN was founded in 2002 in Shenzhen by engineers with experience in the petrochemical industry. Initially produced plastic pellets for injection molding. With the rise of desktop 3D printing in 2010-2013, the company shifted production toward 3D printing filaments.
Their first 3D printing filament, eSUN PLA (2014), was a basic PLA at €15/kg, well below Western competitor prices. This opened doors for hobbyists and beginner 3D printers.
2016, PLA+ (PLA Plus), a modified version with higher impact resistance. Became one of the best-selling filaments worldwide.
2018-2020, Galaxy series (with sparkling crystals in the material), Silk series (metallic shiny effect), eFil Wood and Metal series.
2022, ePA-CF (Nylon with carbon fibers), ePEEK (for specialized applications).
2024, eSilk Magic (triplex color Silk filaments), eBio (biodegradable PLAs with lower carbon footprint).
As of 2026, eSUN produces over 100 different filaments in 30+ colors each. Global market share in the desktop FDM segment, about 15-20%.

Glossary of 3D printing and additive manufacturing terms.
Standard PLA:eSUN €15-€18/kg vs Polymaker PolyLite €28/kg, about 45% cheaper. PETG: eSUN €18-€22 vs Polymaker €28, about 30% cheaper. Carbon Fiber: eSUN ePA-CF €55-€65 vs Polymaker PolyMide PA6-CF €78-€90, about 25% cheaper. For high volume (10+ kg/month), the difference is significant, €200-€500/month in savings.
Yes. eSUN PLA, PETG, ABS, ASA work without problems on Bambu Lab AMS. Standard filaments have similar characteristics to Bambu's own. For optimized AMS settings, set the filament in Bambu Studio as 'Generic PLA' or 'Generic PETG' with small temperature corrections (eSUN PLA usually wants 5°C more than Bambu PLA Basic).
Diameter tolerance. eSUN has ±0.05 mm vs ±0.02 mm for Polymaker. On a printer with PID settings optimized for a tight filament, eSUN can cause micro-fluctuations in flow, visible as a slight color variation along the line. Solution: tune 'flow' by 1-3% (experimental, with a test square in Bambu Studio).
For consumer products (decoration, toys, artistic objects), yes. For industrial prototypes with critical mechanical characteristics, only ePA-CF is acceptable (but without certifications). For certified applications (medical, aerospace), NO. Choose BASF Ultrafuse or Polymaker with full Material Data Sheets.
