eSUN PETG Basic Filament 1.75mm, 1kg

eSUN PETG Basic is a versatile, easy-to-print PETG filament designed for reliable everyday 3D printing. It is a practical choice for functional parts, prototypes, models, fixtures, tools, brackets, housings, mounts, containers, replacement components, and other FDM/FFF 3D printed parts that need more toughness and durability than standard PLA.

PETG, or polyethylene terephthalate glycol-modified, is a popular 3D printing material that combines many of the easy-printing characteristics of PLA with the improved toughness, impact resistance, and environmental resistance associated with PETG. eSUN PETG Basic is suitable for hobbyists, makers, students, designers, engineers, workshops, and professional users looking for a dependable general-purpose filament for a wide range of applications.

Tough, Durable, and Suitable for Functional Parts

eSUN PETG Basic produces strong printed parts with good layer adhesion and reliable mechanical performance. Compared with PLA, PETG is generally better suited to parts that may experience repeated handling, impacts, vibration, moisture, or moderate heat. This makes it a useful material for functional prototypes, workshop accessories, machine components, protective covers, brackets, enclosures, and other parts that need to perform beyond simple visual modelling.

The material offers a useful balance between strength and flexibility. Printed parts are less brittle than many PLA parts and can better tolerate everyday use. As with all 3D printed components, final performance depends on the part design, wall thickness, infill, print orientation, layer height, temperature, cooling, and other slicer settings.

Easy to Print with Low Warping

eSUN PETG Basic is formulated for straightforward printing on compatible FDM and FFF 3D printers. It provides good dimensional stability and low warping when printed with suitable bed preparation and temperature settings. An enclosure is not required, making it accessible for many desktop 3D printers and open-frame machines.

PETG can be more sensitive to printing conditions than PLA, particularly when the filament has absorbed moisture or when the print surface is not properly prepared. For the best results, use a heated build plate, allow the print surface to reach the recommended temperature, and adjust retraction, cooling, and first-layer settings for your specific printer.

Smooth, Glossy Surface Finish

eSUN PETG Basic produces a smooth, glossy surface finish that works well for both functional and visual parts. The filament is available in a selection of solid and translucent colours, allowing you to choose a finish that suits your project.

Solid colours are well suited to prototypes, tools, brackets, housings, fixtures, and finished parts where an opaque appearance is preferred. Translucent colours can be used for decorative models, display pieces, light covers, visual prototypes, and parts where a semi-transparent appearance is desired.

Suitable Applications

eSUN PETG Basic can be used for a wide range of 3D printing projects, including:

• Functional prototypes and engineering models
• Brackets, mounts, clips, and fixtures
• Tool holders and workshop accessories
• Protective covers and equipment housings
• Replacement parts and repair components
• Containers and organizers
• Mechanical prototypes and test parts
• Cosplay, props, and display models
• Educational and classroom projects
• Decorative models and visual prototypes
• Parts exposed to occasional moisture or moderate heat
• General-purpose household and maker projects

PETG is often selected when PLA may be too brittle or when a printed part needs improved resistance to handling and environmental exposure. It is not intended to replace specialized engineering materials in every application, but it provides a useful combination of printability, toughness, appearance, and value for general-purpose 3D printing.

1.75mm Filament on a 1kg Spool

Each spool contains 1kg of 1.75mm eSUN PETG Basic filament. The 1.75mm diameter is compatible with most modern FDM/FFF 3D printers that support 1.75mm PETG filament.

The filament is supplied on a standard spool for convenient storage and use. Keep the spool sealed when not in use and store it in a cool, dry location. PETG is hygroscopic, meaning it can absorb moisture from the air over time. Moisture can contribute to stringing, bubbling, popping, inconsistent extrusion, rough surfaces, and reduced print quality.

If the filament has been exposed to humid air or shows signs of moisture, drying it before printing can help restore more consistent performance.

Recommended Starting Settings

Use the following settings as a starting point and fine-tune them for your printer, nozzle, build surface, model, and preferred print speed:

• Nozzle temperature: 240–260°C
• Build plate temperature: 75–90°C
• Part cooling: 50–100%
• Recommended printing speed: below 250mm/s
• Filament diameter: 1.75mm
• Spool weight: 1kg
• Enclosure: Not required

PETG settings can vary between printers and slicers. A slower first layer, suitable build plate adhesion, and moderate cooling can help improve print quality. Excessive cooling may reduce layer adhesion, while insufficient cooling can affect overhangs, bridges, and fine details. Retraction settings may also need adjustment to reduce stringing.

For best results, dry the filament at 60°C for more than 8 hours when it has absorbed moisture or when print quality has declined.
