If you have ever tried to 3D print a comfortable shoe or insole, you know the struggle: soft TPU (like 75A) feels great but is nearly impossible to print without constant jams, while stiffer TPU (like 95A) prints beautifully but feels like walking on a hard plastic brick.

Enter the BIQU MorPhlex—the world’s first variable hardness flexible filament.

This revolutionary material is specially engineered to print stably as a firm 90A TPU, allowing your extruder gears to grip it easily for clean, tangle-free extrusion. But here is the magic: once the print cools and cures, it transforms into an ultra-soft, skin-friendly 75A. You get the hassle-free printing experience of a rigid filament, with the cloud-like, rebound comfort of premium footwear foam.

Features

• Variable Hardness Technology: Prints firm at 90A for flawless extrusion and bridging, but softens down to 75A post-print for maximum flexibility and comfort.
• The Ultimate Wearables Material: Specifically engineered for printing shoes, slippers, custom orthotic insoles, and soft ergonomic grips.
• Beginner-Friendly Extrusion: Because it feeds into your hotend at 90A, it is vastly more stable than standard ultra-soft filaments, drastically reducing extruder jams and stringing.
• Vibrant & Eco-Friendly: Available in a wide range of eye-catching colors. It is biodegradable, skin-safe, and perfect for prolonged physical contact.
• High Precision: Manufactured with a strict dimensional accuracy of ±0.02mm to ensure consistent flow rates.

Real-World Maker Tips (Printing & Setup)

• NO AMS / MMU: Like all flexible materials, do not run this through the Bambu Lab AMS or any other automated multi-material system. It will stretch, jam, and cause a massive headache. You must feed this directly from an external spool holder (preferably one with smooth bearings) straight into the toolhead.
• Dry It Thoroughly: TPU is incredibly hygroscopic (it absorbs moisture from the air rapidly). Even though it comes vacuum-sealed, we highly recommend throwing it in a filament dryer before your first print to prevent stringing and popping noises.
• Model Selection: If you are printing shoes, look for "segmented" STLs designed specifically for FDM printing. Segmented structures maximize the bending capabilities of the MorPhlex material!
