PLA, PETG, ABS and TPU filament for your 3D printer
3D printer filament is the plastic your printer melts and lays down layer by layer, and the material decides how strong, flexible or heat-resistant the finished part will be. The range comes from Creality, mostly on 1 kg spools of 1.75 mm filament, with 2 kg and 4 kg value packs in PLA and PETG.
PLA is the easiest to print and the usual starting point. PETG is tougher and handles sun and moisture better, ABS resists higher temperatures but needs an enclosure and ventilation, and TPU prints flexible parts such as bumpers and seals. For decorative prints there are silk, matte, rainbow, glow-in-the-dark and wood-filled finishes, while PLA-CF and PETG-CF add carbon fibre for stiffness. Hyper series spools with RFID tags can be recognised by Creality's CFS multi-colour system.
Frequently asked questions
What is the difference between PLA and PETG?
PLA prints at lower temperatures, rarely warps and gives crisp detail, which suits models, prototypes and decorative pieces. PETG is less brittle, more impact-resistant and copes better with heat, moisture and sunlight, so it suits functional parts, outdoor items and containers. PETG tends to string more and usually needs a slightly hotter nozzle and bed.
Which filament diameter do I need?
Most current consumer printers, including Creality Ender, K1 and K2 models, use 1.75 mm filament. Some older or professional machines use 2.85 mm, and the two sizes are not interchangeable. Check your printer's specifications or the label on a spool you already use before ordering.
Do I need a special nozzle for carbon fibre filament?
It is strongly recommended. Carbon fibre blends such as PLA-CF and PETG-CF are abrasive and can wear a standard brass nozzle quickly, which changes its diameter and spoils print quality. Use a hardened steel or similar wear-resistant nozzle, which many newer printers include or offer as an upgrade.
How should I store 3D printer filament?
Many filaments absorb moisture from the air, which causes stringing, bubbles and weak prints. Keep opened spools in a sealed bag or box with desiccant, especially PETG and TPU. If a spool has already absorbed moisture, a filament dryer can usually restore it. Storing spools away from direct sunlight also helps keep colours consistent.
