There is no single "best" filament for all applications. Popular filaments include PLA, ABS, PETG, TPU, nylon, and composites like carbon fiber. The right filament depends on your printing needs - temperature resistance, flexibility, strength, etc. PLA and PETG are good all-purpose options.
PLA is the most common and widely used 3D printing filament. It is easy to print with, biodegradable, and produces decent quality prints. Other common filaments are ABS and PETG.
PLA is better for beginners as it is easier to print with. It sticks well to print beds, has little warping, and does not require a heated bed. ABS can be more difficult due to warping and requirement for higher temperatures.
Yes, PETG is generally considered a more durable and temperature resistant material than PLA. It is tougher and more flexible. However, PLA still has advantages like being easier to print with and more environmentally friendly.
TPU filament can be more challenging to print with than rigid plastics like PLA and ABS. Flexible TPU requires precise dialing in of retraction settings, slower print speeds, and direct drive extruders work best. But with the right printer adjustments, high quality flexible prints are achievable.
Carbon fiber filament provides additional rigidity and strength compared to standard PLA. Carbon fiber is a good option when extra strength and thermal resistance is needed, but for general prints, standard PLA or PETG may be suitable.
