What is SHORE A 85 TPU filament?

SHORE A 85 3D TPU filament is a flexible filament made from thermoplastic polyurethane (TPU) with high flexibility. It is characterized by being:

• High flexibility: This TPU filament is more flexible than most alternatives on the market. li>
• Great resistance:This material has high resistance to elongation, traction and chemicals.

Differences between the different hardnesses of TPU:

At 3DFils we offer 3 different flexible filament hardnesses, each one designed for different applications.

• eFil TPU 85A : This is the lowest hardness we offer. Perfect for applications that require great flexibility but are more difficult to print than the rest.
• eFil TPU 90A : This grade combines its high flexibility with greater ease of printing. Perfect if it is your first time working with this type of 3D printing materials.
• eFil TPU 60D: This is the highest hardness in the catalog. It is very easy to print. Although it does not have as much flexibility as the rest of the products, it is perfect for applications that require resisting strong impacts.

Applications of TPU Shore A 85 filament:

• Flexible parts: Shore A 85 TPU is ideal for printing flexible parts that need to bend or stretch without breaking, such as mobile phone cases, joints, tires, etc., but with a softer texture and pleasant to the touch.
• Prototyping: Shore A 85 TPU can be used to create quick and inexpensive prototypes of parts and designs that need to be flexible and soft to the touch.
• Printing everyday items: Can be used to print a wide range of everyday items, such as footwear, clothing, toys, etc., with a softer and more flexible texture.
• Industrial applications: Shore A 85 TPU is used in various industrial applications, such as the manufacture of hoses, cables,  and automotive parts that require flexibility and soft touch.

Advantages of TPU Shore A 85 filament:

• Flexibility: Shore A 85 TPU is a very flexible material that can bend and stretch without breaking.
• Abrasion resistance: Shore A 85 TPU is resistant to wear and abrasion, making it ideal for applications that require contact with rough surfaces.
• Water and chemical resistance: Shore A 85 TPU is resistant to water, oils and many chemicals. li>
• Good interlayer adhesion: Shore A 85 TPU has good interlayer adhesion, producing high-quality prints.

Disadvantages of SHORE 85A TPU filament

• Printing difficulty: TPU Shore A 85 can be more difficult to print than PLA or ABS as it requires more precise print settings.
• Threading and oozing: Shore A 85 TPU can be prone to threading and oozing, which can affect print quality.
• Moisture Sensitivity:  TPU Shore A 85 is sensitive to moisture, so it is important to store it correctly to prevent moisture from being absorbed.
