BIQU says MorPhlex feeds and prints like 90A TPU, then softens to 75A after printing. That would make it easier to feed than a very soft filament while producing a more flexible finished part. An August 2025 Hackaday report on ModBot’s test, however, measured 80–85A on test cubes—not BIQU’s stated 75A ±3A—so the advertised final hardness is not confirmed by that report.
What BIQU means by “variable hardness”
MorPhlex is a flexible TPU filament. BIQU’s product listing describes it as 90A while being fed and printed, then 75A after printing. In practical terms, the claimed distinction is between a firmer material in the printer’s feed path and a softer finished object.

Those numbers are BIQU’s product claim, not a universally established property. In Maya Posch’s August 16, 2025 Hackaday report on ModBot’s test, MorPhlex test cubes measured 80–85A, with readings varying according to whether the side or top was tested. The report noted that BIQU’s datasheet specified 75A ±3A and raised print temperature and extrusion speed as possible factors in the difference. It does not establish which settings reliably produce a particular final hardness.
What it is intended for
BIQU positions MorPhlex for shoes, slippers, insoles, and soft ergonomic parts. Hackaday’s account of ModBot’s test included slipper prints as well as test cubes. That makes footwear a clear intended application, but it does not prove that a printed shoe will be comfortable, durable, or suitable for a particular wearer.

- 【Warmly Recommend】We strongly recommend using our 3mf file for printing as it contains pre-defined settings. If you plan to manually enter these settings, please use the settings shown in the image
- 【0% Inflation,100% Ball】Craft high-performance airless basketballs with BIQU PLA-HR. Experience the authentic bounce, flight, and feel of a traditional basketball without the need for inflation. The airless basketball printed by BIQU PLA-HR has high resilience, absorbing and returning most of the impact energy to produce a natural bounce
- 【Extreme Durability】When printed with BIQU PLA-HR this ball will weigh between 605g and 610g. The bounce and play response will also be approximately on par with a regular NBA regulation ball provided the recommended print settings are used. Durability of the ball is incredible with it being able to withstand even the roughest play without the structure being compromised
- 【Wide Compatibility】Due to the high-quality standards in manufacturing accuracy and the small diameter tolerance of +/- 0.03mm, it can work perfectly with all common 1.75mm FDM 3D printers. Such as Bambu-Lab X1/P1/A1 Series, FLASH-FORGE Adventurer 5M (Pro), BIQU B1 SE Plus/BX, Ender-3 Series, K1 Max, CR10, Kobra 2, Kobra 3, etc.

For a footwear project, treat the claimed softness as a design possibility to verify in your own print rather than a guaranteed result. The reported cube readings are a useful reason to test the material and settings in a small sample before committing to a larger part.
BIQU’s listed printing and handling guidance
BIQU’s listing, accessed in 2026, gives the following specifications and recommendations. These are maker-provided guidance, not independently established optimum settings; check the current listing and your printer’s requirements before printing.

| Filament diameter | 1.75 mm |
| Nozzle temperature | 225–260°C |
| Flow rate | 2.8–4 mm³/s |
| Feeding | BIQU recommends direct feeding. |
| Drying and storage | BIQU recommends fully drying the filament and storing it in a cool, dry, dark place. |
| Bambu Lab AMS | BIQU says MorPhlex is not compatible with Bambu Lab AMS systems. |
The Hackaday report says the sample was dried before testing. Drying is therefore relevant both as maker guidance and as part of the conditions described in that report, but the published account does not supply a complete, repeatable settings recipe for reaching a target hardness.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What is still uncertain
The available sources do not establish the chemical mechanism behind the claimed change, a reliable relationship between print settings and finished Shore A hardness, or long-term wear and comfort in footwear. Hackaday’s 80–85A cube readings come from one reported test account, not a repeated comparative study. They should not be treated as a universal hardness range for every print.

MorPhlex’s distinctive promise is a firmer-feeding TPU that becomes softer as a printed part. BIQU specifies a 90A-to-75A shift, while the reported independent measurements landed at 80–85A on test cubes. Anyone choosing it for a particular flexibility or fit should validate a sample under their own printer setup.
