Serviceable FEP Frame – Anycubic Photon Mono

I designed a replacement FEP frame for the Anycubic Photon Mono because original replacements are becoming difficult to find and many existing designs online are not very reliable.

This version is fully serviceable , meaning you can easily replace the FEP film without needing a new frame.

The design has been tested on my own printer , and after several iterations it works reliably.

Hardware Required

- 14 × M2.5 heat set inserts (L4 × OD3.5)

- 14 × M2.5 × 6 mm countersunk flat head screws

FEP Installation

- Cut a piece of standard FEP film slightly larger than the frame .

- Place the FEP between the two frame parts.

- Install the screws and tighten them evenly.

- After tightening, trim the excess FEP around the edges.

Installation on the Vat

Mount the assembled FEP frame onto the vat.

Tighten the vat screws in a cross pattern , gradually and evenly.

Print Settings (tested)

Material: ABS

- 40% infill – Gyroid

- Ironing enabled on top surface

- Print speed: 60 mm/s

- Flow: 30 %

Notes

I printed 5 prototypes before achieving the final fit and tension. The frame has been tested on my own Anycubic Photon and works correctly.
