What filament can the Geeetech A20M print?
A guide to the materials the Geeetech A20M can handle, based on its hotend, heated bed specs.
| 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 | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. |
| 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) | Not ideal | Not recommended - PC needs very high hotend temps and an enclosed chamber. |
| 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. |
