Flexible 3D Printer Filament Flashforge FLT1 1.75 mm Natural 1 kg

Flexible 3D Printer Filament Flashforge FLT1 1.75 mm Natural 1 kg is a soft, elastic filament formulated for printing flexible parts and prototypes. The filament has a 1.75 mm diameter and is supplied on a 1 kg spool for uninterrupted printing. Designed for compatible FDM/FFF printers that accept 1.75 mm filament, this material delivers impact resistance and elasticity suitable for wearable items, seals, grips and other soft functional models. The natural translucent color provides a neutral base for post-processing or dyeing.

Advantages

This Flashforge FLT1 flexible filament combines elasticity with reliable feeding on standard extruders that support 1.75 mm material. It offers consistent diameter and spooled supply for stable extrusion and fewer jams when printers are calibrated correctly. The material's impact resistance and flexibility make it useful where parts must deform and recover repeatedly without immediate failure. The natural shade is versatile for prototyping and final parts that require low visibility of layer lines or further finishing.

Suitable for

• Wearable components such as wristbands, straps and soft clasps
• Gaskets, seals and flexible couplings
• Grips, handles and ergonomic surfaces
• Soft prototypes, bumpers and impact-absorbing parts
• Functional models that require repeated bending or compression

Key specifications

• Material type: flexible elastomeric filament suitable for FDM/FFF printing
• Diameter: 1.75 mm nominal for standard extruders
• Spool weight: 1 kg net filament per spool
• Color: Natural (translucent/neutral)
• Compatibility: suitable for printers supporting 1.75 mm filament and flexible materials with appropriate extruder setup

How to use

Load the Flashforge FLT1 1.75 mm filament into a printer configured for 1.75 mm filament and capable of handling flexible materials. Set extrusion temperature, print speed and retraction settings according to your printer manufacturer’s guidelines for flexible filaments; typical profiles use lower print speeds and reduced retraction to avoid filament buckling. Ensure the filament path is constrained and a direct-drive or properly tuned Bowden setup is used to minimize compression in the feed path. Print on a prepared build surface and allow adequate cooling and layer bonding based on print geometry.

Recommendations

Use moderate extrusion temperatures and slow print speeds for best dimensional accuracy. Disable or reduce retraction and keep a short, supported filament path to prevent jams. Store spools in a dry place or sealed bag with desiccant to maintain filament performance. Test small samples to fine-tune printer settings before producing critical or large parts.
