3D Printer Filament eSun PETG 1.75 mm Silver 1 kg

eSun PETG 1.75 mm Silver is a 1 kg spool of PETG filament designed for FDM/FFF 3D printers that accept 1.75 mm material. PETG combines the strength and stiffness of PET with improved impact resistance and flexibility, offering reliable layer adhesion and chemical resistance. The silver color provides a neutral, slightly metallic finish suited for functional prototypes, mechanical parts, and visual models where moderate heat resistance and dimensional stability are required.

Advantages

PETG filament balances strength and flexibility, producing durable parts with good interlayer bonding and low warping compared with some other thermoplastics. The material demonstrates resistance to common chemicals and moisture uptake, making it suitable for parts exposed to light mechanical stress or humid conditions. The 1.75 mm diameter ensures broad compatibility with a wide range of desktop FDM/FFF printers, and the 1 kg spool provides a practical amount of filament for prototyping and small production runs.

Suitable for

• Functional prototypes and end-use parts requiring toughness
• Mechanical components, brackets, and housings
• Visual models and display items with a neutral metallic look
• Parts exposed to mild chemicals or moisture

Key specifications

• Material: PETG (glycol-modified polyethylene terephthalate)
• Diameter: 1.75 mm
• Net weight: 1 kg spool
• Color: Silver (metallic neutral finish)
• Recommended printing temperature range: typically 220–250 °C (verify with printer and settings)
• Recommended bed temperature: typically 60–80 °C
• Compatibility: FDM/FFF 3D printers using 1.75 mm filament

How to use

Load the spool onto the printer spool holder and feed the 1.75 mm filament through the extruder according to your printer manufacturer’s instructions. Preheat the hotend and build plate to the recommended temperatures for PETG and perform initial extrusion to verify consistent flow. Print at moderate speeds to promote good layer adhesion and avoid excessive stringing; adjust retraction settings and print cooling as needed. After printing, allow the part to cool on the build plate to reduce the risk of dimensional change before removal.

Usage recommendations

Store the filament in a dry environment and keep it sealed when not in use to limit moisture absorption. Calibrate extrusion multiplier and first-layer settings for reliable dimensional accuracy. For improved surface finish, use a coated or clean glass bed and consider a thin glue stick or PET tape to enhance first-layer adhesion if required.
