What filament can the Wanhao D12-300 print?
Filament compatibility for the Wanhao D12-300: the materials Wanhao lists for it.
| Filament | Suitability | Notes |
|---|---|---|
| PLA | Great | On the maker's list of materials for this printer. |
| PETG | Great | On the maker's list of materials for this printer. |
| TPU & flexibles | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. |
| ABS & ASA | Great | On the maker's list of materials for this printer. |
| Nylon (PA) | With care | Possible with care - an enclosure and very dry filament are essential. |
| Polycarbonate (PC) | Great | On the maker's list of materials for this printer. |
| 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. |
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
