Printing Formism Persona shoes at home requires specific hardware, materials, a well-thought-out slicing strategy, and post-processing.
Hardware Recommendations
Bambu Lab desktop printers are the primary hardware recommendation. While alternative high-end FDM machines with stable direct-drive extruders may work, they require fine-tuning for optimal results.
Material Choices: The Importance of TPU
Flexible filament, particularly thermoplastic polyurethane (TPU), is recommended for printing shoes. Bambu Lab TPU 90A and 95A are commonly mentioned by users. TPU 98A, however, might prove too stiff for a shoe’s upper material, which could compromise comfort. For Persona Unisex shoes, the design specifically caters to 90A TPU, as mentioned on its MakerWorld page. Users have noted that 85A TPU results in a softer upper; in such cases, the infill density of the sole can be increased if needed. One user suggested using 82A TPU for the outsole of a clog and 68A TPU for the lining.
Recommended Print Settings (Example for a Clog)
Achieving a successful print requires careful attention to settings. Here is an example for a clog:
| Setting | Value | Notes |
|---|---|---|
| Layer Height | 0.36 mm | A balance between detail and print speed. |
| Nozzle Size | 0.6 mm | Larger nozzles can speed up prints but may reduce fine detail. |
| Top Support Distance | 0.64 mm | Ensures easy removal of support structures. |
| Bottom Support Distance | 0.6 mm | Similar to top support, for clean separation. |
| Print Speed | 50-60 mm/s | Crucial for flexible filaments to prevent issues like stringing or clogs. |
| Fan Speed | 20-50% | Helps with cooling without causing warping. |
| Infill (Clog Upper) | "Locked Zag" (25%-55%-30%-1mm-2mm) | Specific pattern for desired flexibility and strength. |
| Infill (Insole) | TPMS-FK (Orcaslicer) | Can be tested for optimal cushioning. |
A user successfully printed an Arc Clog in US size 12 using Bambu TPU 95 HF with a 0.4 HF nozzle at 105%, documented on MakerWorld. However, TPU 95 offers limited grip on hard surfaces. The cost for printing a pair at home ranges from $5 to $30+ for filament, in addition to electricity and post-processing expenses.
User Experiences and Challenges
Early adopters have encountered various challenges, highlighting the learning curve involved in 3D printing footwear.
Common Issues Reported
- Durability: Some users reported issues with the Arc Sneaker, where the heel wall was too thin and tore when worn.
- Fit: Others found Arc Sneakers to fit snugly and recommended printing a half to full size larger for comfort. For laceless shoes, printing one size larger is often recommended to accommodate varying instep heights.
- Print Failures: One user experienced significant slicing errors with the Persona Sneaker from layer 884 onwards, where the tool head extruded without moving, leading to material waste.
- Material-Related Defects: Similar defects appeared when using 85A TPU for the Persona Sneaker, with a user suspecting undried filament or excessive print speed as potential causes.

Sizing and Calibration
The sizing system for the Persona models initially suffered from errors due to conflicts with the crowdfunding format. Formism later provided a "Size File" with scaling ratios for manual size adjustment. It is also noted that Persona Sneakers will not be larger than Arc Sneakers. A user printing a Persona shoe in US size 15.5 had to adjust the angle to fit it within the build volume of a Snapmaker U1. This particular printed shoe, using TPU 95A, turned out "hard as a rock," indicating excessive infill density and wall thickness. One shoe required 30 hours of print time and an entire spool of filament.
Filament Flexibility and Print Time
Another user printed the Arc Clog with Kingroon 95A TPU, finding it too stiff and inflexible. They planned to use 75A TPU for the second clog for increased comfort. While the 75A TPU print was more challenging to calibrate and resulted in poorer print quality, it took 22 hours and 30 minutes to complete.
