Introduction: Flexibility That Fuels Creativity

In the dynamic world of additive manufacturing, flexible filaments have opened up endless possibilities. From custom phone cases to soft robotics and wearable tech, the need for adaptable and resilient materials is greater than ever. One of the industry’s most trusted names in Flexible 3D Printing Materials is eSUN3D. Known for their quality, innovation, and affordability, eSUN’s flexible filaments are widely used by hobbyists, educators, and professionals alike.

Understanding Flexible 3D Printing Filaments

Flexible filaments are made from thermoplastic elastomers (TPEs)—materials that combine the elasticity of rubber with the processing advantages of plastic. These filaments can bend, stretch, and compress without losing shape, making them perfect for functional parts subjected to mechanical stress or wear.

Two of the most popular flexible materials from eSUN3D are:

  • TPU (Thermoplastic Polyurethane)

  • eFlex (a softer, highly elastic filament)

eSUN TPU: A Durable Workhorse for Functional Prints

eSUN’s TPU 95A is a well-balanced filament offering strength, flexibility, and printability. It is favored for both personal and industrial applications due to its reliable performance.

Key Features of eSUN TPU:

  • Shore hardness of 95A for moderate flexibility

  • Excellent abrasion and impact resistance

  • Resistant to oils, greases, and many chemicals

  • Compatible with most FDM 3D printers with direct drive extruders

Typical Applications:

  • Phone and tablet cases

  • Bicycle grips and protective pads

  • Automotive seals and grommets

  • Flexible connectors and mechanical parts

eSUN eFlex: Ultra-Soft and Skin-Safe

If your project demands greater softness and stretchability, eFlex is an excellent choice. This proprietary blend has a Shore hardness around 85A, making it ideal for soft-touch applications.

Advantages of eFlex:

  • Greater elasticity compared to TPU

  • Gentle on skin—perfect for wearable parts

  • Strong interlayer bonding

  • Excellent for printing textures and surfaces with grip

Common Use Cases:

  • Orthotic and prosthetic devices

  • Wristbands, fitness trackers, and wearable tech

  • Soft buttons, knobs, and toys

  • Impact-absorbing parts in robotics
