FLEX 90 filament Plexiwire 0.9 kg 1.75 mm Green

Elastic plastic for a 3D printer

FLEX 90 plastic Plexiwire 1.75 mm — is an elastic filament based on thermoplastic polyurethane (TPU) that combines the best properties of rubber and engineering plastic. The material is designed for 3D printing of products requiring high flexibility, impact strength, and the ability to restore shape after deformation. Shore 90A hardness corresponds to dense rubber (like a shoe sole). This stiffness makes this filament more stable when fed into the extruder compared to overly soft FLEX types, allowing for successful printing with it on most FDM printers, provided low speeds are maintained.

Advantages of Plexiwire FLEX 90 filament

Choosing flexible plastic from Plexiwire allows you to create functional parts with specific physical properties:

• High elasticity. Products can stretch 2-3 times (up to 300%) of their original size while maintaining their integrity and properties.
• Wear resistance and strength. The material is resistant to abrasion, tearing, and repeated bending, which guarantees the durability of parts.
• Chemical inertness. FLEX 90 is resistant to oils, fats, many solvents, and aggressive liquids.
• Wide temperature range. Finished models retain their properties within the range of -40°C to +70°C.
• Minimal shrinkage. Low thermal shrinkage coefficient and excellent adhesion to the platform allow for printing parts with stable geometry.

Application Options

Due to its cushioning ability and flexibility, FLEX 90 Plexiwire is widely used in the following areas:

• Industry and auto service: manufacturing of oil seals, seals, gaskets, bushings, and protective boots.
• Robotics: creation of damping elements, vibration-proof mounts, and flexible joints.
• Consumer electronics: protective cases for gadgets, shockproof bumpers, and ergonomic covers.
• Sports and footwear: printing sole elements, elastic inserts, and equipment.
• Prototyping: creating copies of rubber or silicone products to test shape and functionality.

Technical Tips

Printing with flexible filaments requires special equipment settings. For a successful result with FLEX 90, follow these recommendations:

• Temperature mode: nozzle 230°C – 250°C, platform 50°C – 80°C.
• Printing speed: low speed is recommended — up to 30 mm/s. This is critically important so that the filament does not bend or slip between the drive gear and the extruder wheel.
• Feeding mechanism: it is best to use a printer with direct feed (Direct). There should be no free space between the extruder wheel and the thermal barrier. Do not apply too much pressure on the filament from above to avoid bending it.
• Nozzle cleanliness: we recommend using a separate nozzle for this filament. Residues of other types of hard plastics can deform the soft FLEX filament and complicate the process.
• Filament feeding: ensure free movement of the filament without any resistance so that the extruder does not "pull" the material — this prevents unwanted stretching or bending of the filament.
• Drying and storage: the material actively absorbs moisture. Be sure to dry it before work and store it in airtight conditions.
