Wood Filled Wood filaments combine a PLA base material with cork, wood dust, or other derivatives, giving the models a real wooden look and feel. Metal Filled Metal filled filaments are made by mixing a fine metal powder into a base material, providing a unique metallic finish and added weight. Polycarbonate Polycarbonate is known for its strength and durability. It has very high heat and impact resistance making it an ideal choice for tough environments. ASA ASA is a common alternative to ABS and is great for outdoor applications due to its high UV, temperature, and impact resistance. Carbon Fiber Filled Carbon fiber filaments contain short fibers that are infused into a PLA or ABS base material to help increase strength and stiffness. PETG PET and PETG filaments are known for their ease of printability, smooth surface finish, and water resistance. HIPS HIPS is a lightweight material most commonly used as a dissolvable support structure for ABS models. PLA PLA is the go-to material for most users due to its ease-of-use, dimensional accuracy, and low cost. ABS ABS is a low cost material, great for printing tough and durable parts that can withstand high temperatures.
