What filament can the Velleman Vertex K8400 print?
Filament compatibility for the Velleman Vertex K8400: 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 | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. |
| ABS & ASA | With care | Borderline - the bed runs a little cool and an enclosure is essential for ABS and ASA. |
| Nylon (PA) | Not ideal | Not recommended - nylon needs a hotter hotend (~250-270C) and ideally an enclosure. |
| 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. |
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.
