PETG 1.75 mm Flashforge FG171-3002 filament, Lipstick Red, 1 kg spool

Flashforge PETG 1.75 mm filament in Lipstick Red is a 1 kg spool designed for FDM/FFF 3D printers that accept 1.75 mm filament. PETG combines mechanical strength, chemical resistance and good interlayer adhesion with relatively low warping compared to many other thermoplastics. The material is suitable for producing functional parts, prototypes and visually appealing decorative prints where durability and moderate flexibility are required. Keep the spool dry and protected from dust to preserve print performance and filament feeding reliability.

Advantages

This PETG filament offers a balance of toughness and ease of printing: strong printed parts with good layer bonding and resistance to impact and many chemicals. Lipstick Red color provides consistent pigmentation for visual parts and visible prototypes. The 1.75 mm diameter ensures compatibility with a wide range of contemporary desktop FDM/FFF printers and reliable extrusion through standard hotends when print settings are adjusted appropriately. Low tendency to warp reduces the need for heated enclosures while enabling larger prints with fewer adhesion issues.

Suitable for

• Functional mechanical parts and housings
• Prototypes and concept models
• Decorative objects and display elements
• Outdoor or semi-exposed components requiring chemical or moisture resistance
• Multi-color assemblies where a vivid red is needed

Key specifications

• Material: PETG (polyethylene terephthalate glycol-modified)
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg net filament
• Color: Lipstick Red
• Filament form: single continuous filament on a spool
• Compatibility: standard 1.75 mm FDM/FFF desktop printers

How to use

Install the spool on the printer’s filament holder ensuring smooth feeding into the extruder. Set the printer to PETG or a similar temperature profile; typical nozzle temperatures range from 230–250°C and a heated bed between 60–80°C is recommended to improve adhesion. Use a moderate print speed and enable retraction settings appropriate for PETG to reduce stringing. Calibrate extrusion multiplier and first layer height for consistent flow and adhesion. After printing, allow parts to cool before removal to minimize deformation.

Usage recommendations

Store the filament in a dry environment or sealed with desiccant to prevent moisture uptake which can cause poor surface finish and increased stringing. For best results on flat parts, use a suitable bed surface such as PEI, glass with adhesive or a textured build plate, and consider a brim for improved first-layer stability. Adjust cooling fan settings lightly: some parts benefit from reduced cooling to improve layer adhesion while others may require moderate cooling to maintain detail.
