Formism Persona Package - Unisex Shoes V2

Description

The Persona Series marks the first footwear digital asset release from FORMISM. It consists of three models engineered to industrial standards, prioritizing structural mechanical performance, design completion, and FDM compatibility over mere visual aesthetics.
-

In partnership with Bambu Lab, FORMISM aims to bridge the gap between digital design and high-end physical products. We enable users to achieve production-grade wearability and mature aesthetics at home, while building a robust FDM footwear manufacturing framework.

File Information

• This model features a zoned-modular design. We encourage users to utilize multi-extruder or multi-material switching systems to assign filaments of various colors or properties to specific components—such as the sole, upper, and connectors—enabling a wide range of highly personalized colorways and material combinations.

   

• The midsole features an integrated zonal design. Users can calibrate the cushioning and softness of the sole by fine-tuning the infill density of the model.

Sizing & Fit

• The footwear models are integrated with a brand-new parametric sizing system. This allows you to flexibly select the size according to your individual needs, ensuring a high-precision fit for the final printed product. We recommend sizing up by one size to prevent an undersized fit and to accommodate potential insoles.

Material Selection

• Footwear Body:
  • Bambu Lab TPU 90A
  • Bambu Lab TPU 85A 
  • Foam TPU
• Support:

  • PLA

     

• TPU is a flexible filament. Due to its high hygroscopicity and physical elasticity, it is significantly more challenging to print than standard rigid materials like PLA. Improper handling can easily lead to extruder clogging, severe stringing, or total print failure.

   

• Since PLA and TPU do not adhere to each other, utilizing PLA as the support interface allows for effortless removal of the support structures, resulting in a significantly smoother and cleaner print surface.

   

Printing & Technical Guidelines

• Before printing, please ensure you have thoroughly read the "Bambu Lab Official TPU Printing Guide" and strictly adhere to the following requirements:

   

  • NO AMS: TPU is too flexible for the AMS automatic feeding system. You must use the rear spool holder for manual loading.

     

  • MANDATORY DRYING: Filaments must be dried at 55°C for at least 6 hours before use. Undried TPU will cause bubbles and significant loss of structural integrity.

     

  • FLOW CONTROL: Flexible materials are highly sensitive to extrusion pressure. Please strictly follow the speed limits in the official slicer presets—do not increase print speeds arbitrarily.
