eSUN ePLA-ST is a PLA filament developed to be stronger and more durable than general PLA. It offers high impact resistance, great flexibility, and prints as easily as standard PLA, making it suitable for parts requiring mechanical durability.

What is eSUN ePLA-ST?

eSUN ePLA-ST (Super Tough PLA) is a specially developed 3D printer filament that combines the strengths of standard PLA (easy to print, no warping) with engineering-grade durability. This results in a filament that is stronger than PETG and highly flexible, making it suitable for parts that require high impact resistance in everyday use.

Key Features of eSUN ePLA-ST

• High Impact Resistance – IZOD Impact Strength up to 63 kJ/m², superior to PETG and general PLA+.
• High Elongation at Break – Elongation at Break up to 90%, not easily broken under tensile force.
• Easy to Print, No Warping – Prints easily like general PLA, no enclosure needed, no warping even for large objects.
• High Layer Bonding – Printing layers bond tightly, resulting in strong and durable parts.
• High Precision – Produced with low variability tolerance, consistent feeding, no nozzle clogging.

ePLA-ST Comparison with Other Filaments

Property	PLA	PLA+	PETG	ePLA-ST
Impact Resistance	Low	Medium	Medium	Very High

• Print Speed: 40–60 mm/s (for Direct Drive, reduce speed slightly)
• Enclosure: Not required
• Cooling Fan: Recommended to turn on

What is it suitable for?

eSUN ePLA-ST is suitable for:

• Mechanical parts, gears, hinges, clip locks
• Brackets and fixtures that need to bear weight
• Toys, models that need to withstand heavy use
• Phone cases and portable device accessories
• DIY parts for home repairs
• Engineering prototypes

Available Colors

eSUN ePLA-ST is available in several colors including Black, Grey, Natural White, and other colors depending on stock availability. 1.75mm diameter filament, 1 kg per roll.

Summary

eSUN ePLA-ST is an excellent choice for those who need to print parts with high impact resistance while still enjoying the ease of printing of traditional PLA. It combines the advantages of PLA and engineering materials, resulting in strong, durable, and easy-to-produce parts.

If you are looking for a filament for applications requiring higher durability than general PLA, but without the complexity of ABS or Nylon — eSUN ePLA-ST is the right answer for you
