### What works with SimplyPrint

Connected through Klipper (Moonraker), SimplyPrint supports most of what it offers on the Prusa MK3.5: the camera and AI failure detection, remote printing, skipping objects, temperature and movement control and AutoPrint. Not yet in SimplyPrint through Klipper (Moonraker): download the file before the print starts. Not available through Klipper (Moonraker): print binary G-code (.bgcode) and sync loaded filament from the multi-material unit.

## Automate the Prusa MK3.5

### Ways to automate it

- [Your own ejection G-code](https://staging.simplyprint.io/features/autoprint/custom): Write the routine that clears your plate, and AutoPrint runs it after every print.
- [A robot arm, or anything with an API](https://staging.simplyprint.io/features/autoprint/api): Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system.
- [Clear it by hand, keep the queue](https://staging.simplyprint.io/features/autoprint/manual-mode): AutoPrint waits for you to mark the plate clear, then starts the next job.

[How AutoPrint works](https://staging.simplyprint.io/features/autoprint). AutoPrint comes with the Pro plan and up.

## What filament can the Prusa MK3.5 print?

Filament compatibility for the Prusa MK3.5: the materials it can handle, judged from its hotend, bed, chamber and enclosure.

| Filament | Suitability | Notes |
| :--- | :--- | :--- |
| PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. |
| PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). |
| TPU & flexibles | Great | The direct-drive extruder feeds flexible filament well. Print slowly for clean results. |
| ABS & ASA | With care | The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints. |
| Nylon (PA) | With care | Possible with care - an enclosure and very dry filament are essential. |
| Polycarbonate (PC) | With care | On the edge - PC really wants an enclosed, hot chamber to avoid warping. |
| Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. |
