Is eSUN filament good quality?

eSUN is a good budget filament brand — consistent quality, broad material range (PLA through Nylon and PC), and widely available. It is not in the same tier as Prusament or Polymaker for tight-tolerance engineering parts, but is reliable for general printing. eSUN's biggest advantage is material breadth: they make one of the widest selections of specialty materials (Wood PLA, Silk PLA, ABS+, PLA+, Metal-fill) at budget prices.

What is the difference between eSUN PLA and ePLA+?

eSUN ePLA is standard PLA: lightweight, easy to print at 200–220°C, 50–60°C bed. eSUN ePLA+ uses a modified formula that increases tensile and impact strength significantly over standard PLA at a small cost premium. ePLA+ requires slightly higher temperatures (220–230°C) and is tougher for functional parts like brackets and clips. If you are printing purely for looks, standard ePLA is fine. For parts that need to flex slightly without snapping, ePLA+ is worth the extra cost.

eSUN Filament Settings

eSUN offers one of the broadest material ranges of any budget filament brand — from standard ePLA through engineering materials like ePA Nylon and eABS. These settings cover the main eSUN filament lines for FDM printing.

Settings by material

ePLA

Nozzle temp200–230°CStart at 215°C

Bed temp50–60°C

Retraction1 mm (DD) / 4–5 mm (Bowden)

Fan100%

Print speed40–80 mm/s

eSUN ePLA is a reliable budget PLA. Prints slightly hotter than Hatchbox PLA for best results — start at 215°C. Good surface finish and wide color range. eSUN PLA+ runs stiffer and tougher, requiring 220–230°C.

ePETG

Nozzle temp230–250°CStart at 240°C

Bed temp70–85°C

Retraction1–2 mm (DD) / 5–6 mm (Bowden)

Fan30–50%

Print speed30–50 mm/s

eSUN ePETG is a solid budget PETG. 240°C nozzle at 80°C bed on textured PEI is the standard starting point. Prone to mild stringing — use combing mode and reduce temperature before increasing retraction.

eABS

Nozzle temp230–250°CStart at 240°C

Bed temp100–110°C

Retraction1–2 mm (DD)

Fan0%

Print speed40–60 mm/s

eABS is one of eSUN's budget materials. Enclosure strongly recommended. eSUN also makes eABS+ which has lower warp tendency than standard eABS — preferred for large flat parts.

eTPU 95A

Nozzle temp220–240°CStart at 230°C

Bed temp30–60°C

Retraction0–1 mm (DD)

Fan100%

Print speed20–35 mm/s

eSUN eTPU 95A requires direct drive. Print slowly — 25–30 mm/s. The eSUN formulation is slightly stiffer than Polymaker PolyFlex at the same Shore A rating, which can make it slightly more Bowden-compatible at very slow speeds.

ePA (Nylon)

Nozzle temp230–260°CStart at 250°C

Bed temp70–90°C

Retraction0.5–1 mm (DD)

Fan20%

Print speed30–60 mm/s

ePA must be dried before printing (12–24h at 70°C). Nylon absorbs moisture extremely fast — print directly from a drybox. PEI + glue stick at 80°C is the best bed adhesion approach. Enclosure recommended.
