BIQU Morphlex – Variably Hard Flexible Filament for 3D Printing, 1.75mm, 1kg

Ideal for printing soles, ergonomic grips, soft accessories, and functional prototypes with different hardness within a single print.

Special Features

• Variable hardness within one filament

  BIQU Morphlex filament allows you to change the resulting material hardness in the range of Shore 65A–90A by changing the printing temperature, without changing the spool.

• Superior interlayer adhesion

  Even at lower hardness, the filament maintains excellent layer cohesion and low deformation.

• High elasticity

  It can be stretched up to 680 % without breaking – ideal for applications requiring extreme flexibility.

• Compatibility with standard extruders

  Printable on most common FDM printers, including those with direct and bowden extruders. (For bowden, we recommend lower speeds.)

Recommended Print Parameters

• Filament diameter: 1,75 mm

• Printing temperature: 200–260 °C

  • 200 °C = lower hardness (approx. 65A)

  • 260 °C = higher hardness (approx. 90A)

• Bed: 40–60 °C

• Printing speed: 20–40 mm/s (slower recommended for better quality)

• Bed surface: PEI, textured sheet or glue (better adhesion)

Packaging

• Spool weight: 1 kg (net filament weight)

• Vacuum packed with desiccant bag

Tip from 3D Stisk

By changing the printing temperature during the print, you can create zonally different hardness (e.g., sole + infill with different hardness). Ideal for personalized products.
