Materials

Quick answerDry all engineering filaments before every print session — including freshly opened factory-sealed spools. PLA and PETG benefit from drying if stored open for more than a week. Use a dedicated filament dryer or food dehydrator.

Quick answerUse PLA for visual models and display pieces. Use PETG for functional indoor parts with light loads. Move to engineering materials when temperature, impact, UV exposure, chemical contact, or sustained mechanical loads are involved.

Quick answerStore all filaments in sealed containers or bags with fresh desiccant. Engineering filaments — particularly Nylon, PC, and PPA-CF — should be treated as moisture-sensitive at all times and stored in airtight containers between print sessions.

Quick answerCarbon fibre reinforcement increases stiffness and heat resistance significantly but always requires a hardened steel nozzle and produces more brittle parts than the unreinforced base material. The CF does not add toughness — it adds rigidity.

Quick answerUse a dedicated support filament for clean, damage-free removal. Bambu Support for PLA/PETG, Bambu Support for ABS, Polymaker PolySupport, PVA for dissolvable, and HIPS for ABS/ASA. For engineering materials like Nylon and PC where no dedicated support exists, same-material supports with tuned interface settings are the fallback.
