3D Printing Accessories FAQ
What accessories do I need for my first 3D printer?
Every beginner needs a 3D printing tool kit (scrapers, pliers, cutters), a PEI magnetic build plate for better adhesion, and isopropyl alcohol (IPA) for bed cleaning. A filament dryer is recommended if you print with PETG, TPU, or Nylon, as moisture degrades these materials. See our beginner's buying guide for a complete setup checklist.
Do I need a filament dryer?
If you print with hygroscopic filaments like PETG, TPU, Nylon, or ABS — yes, a filament dryer is essential. Moisture-absorbed filament causes stringing, bubbling, and weak layer adhesion. The SUNLU FilaDryer S2 is our top pick, handling standard 1kg spools at adjustable temperatures from 35–55°C. Even PLA benefits from drying in humid climates.
When should I replace my 3D printer nozzle?
Replace your nozzle every 3–6 months with regular use, or sooner if you print with abrasive filaments like carbon fiber, glow-in-the-dark, or wood-fill. Signs of a worn nozzle include inconsistent extrusion, under-extrusion, and rough surface finish. Hardened steel nozzles last 5–10× longer than brass and are essential for abrasive materials. Check our filament guide to know which materials require hardened nozzles.
Is a 3D printer enclosure worth it?
An enclosure is essential for printing ABS, ASA, and Nylon — these materials warp without consistent ambient temperature. Even for PLA, enclosures reduce noise, contain fumes, and protect prints from drafts. If your printer doesn't come enclosed, aftermarket enclosures like the Creality enclosure are affordable upgrades. Browse our mid-range printers if you want built-in enclosures.
