ESUN PLA+ 1.75mm Silver 1kg Refill 3D Filament (PLA+175S1R1)

Makers upgrading from standard PLA to a tougher material for functional prototypes will appreciate the ESUN PLA+ in silver. This 1 kg refill coil fits reusable master spools, reducing plastic waste without sacrificing print quality. The 1.75 mm filament extrudes smoothly at 205–225 °C, delivering parts with a glossy surface and low warping on a heated bed at 60 °C.

Key specifications

• Material: PLA+ (Polylactic Acid Plus)
• Diameter: 1.75 mm (±0.03 mm tolerance)
• Net weight: 1 kg
• Colour: Silver
• Print temperature: 205–225 °C
• Bed temperature: 25–70 °C (recommended 60 °C)
• Tensile strength: 50–70 MPa
• Elongation at break: 30–50%
• Density: 1.24 g/cm³
• Spool type: Refill coil (requires reusable master spool)
• Packaging: Vacuum sealed with desiccant

Why choose it

PLA+ offers higher impact resistance and flexibility than regular PLA, making it suitable for parts that need to withstand occasional stress. The silver finish hides layer lines well, and the tight diameter tolerance ensures consistent extrusion. Since it comes as a refill, you can reuse your existing master spool and reduce plastic waste.

Ideal use cases

• Functional prototypes that require more durability than standard PLA
• Cosplay props and decorative items needing a metallic silver look
• Educational projects where ease of printing is essential
• Household tools and jigs that benefit from PLA+ toughness

Good to know

Store the filament in a dry environment to maintain print quality. The vacuum-sealed packaging with desiccant helps preserve the material until first use. A heated bed is recommended to improve adhesion and reduce warping. This refill coil is compatible with most FDM 3D printers that accept 1.75 mm filament and a reusable spool system.
