eSUN PLA+ 1.75mm Orange 1kg Refill 3D Filament (PLA+175O1R1)

With a tensile strength of ≥60 MPa and an elongation at break of ≥25%, eSUN PLA+ Orange 1.75mm refill filament delivers exceptional toughness for reliable, high-quality 3D printing. This 1 kg spool-less refill is engineered for FDM printers, offering the perfect balance of strength and ease of use.

Overview

eSUN PLA+ is a premium modified PLA (Polylactic Acid Plus) filament that enhances the mechanical properties of standard PLA. It is ideal for functional prototypes, artistic models, and everyday printing projects where durability and print quality are paramount. The filament comes in a vibrant orange colour, adding a striking finish to your creations. The refill format is designed for users who already have a reusable spool, reducing waste and cost.

What stands out

• High tensile strength (≥60 MPa) and excellent elongation (≥25%) for tough, impact-resistant prints.
• Precision diameter of 1.75 mm with a tight tolerance of ±0.03 mm ensures consistent extrusion and reliable feeding.
• Low odour and low warpage make it user-friendly, even for indoor printing environments.
• Bubble-free and biodegradable material, packaged vacuum-sealed with desiccant for optimal moisture protection.
• Wide compatibility with most FDM 3D printers, including those with direct drive or Bowden extruders.
