Filament is essentially a thermoplastic material used as the raw material for creating objects during 3D printing. The process of 3D printing builds a three-dimensional object from a digital file by laying down successive layers of material. The material used, mainly plastic, is known as the filament.
Filament comes in two primary materials – thermoplastics and thermosets. Thermoplastics can be melted and reshaped multiple times, while thermosets can only be heated and shaped once. In 3D printing applications, we mainly use thermoplastics in the form of PLA and ABS.
PLA (Polylactic Acid) is a biodegradable thermoplastic derived from renewable resources such as corn starch or sugarcane. It is one of the most popular filaments used by 3D printing enthusiasts as it offers better print quality and lower warping, ensuring clean and smooth finishes. It is ideal for making objects that do not require high strength or durability.
ABS (Acrylonitrile Butadiene Styrene) is a stronger thermoplastic that provides higher impact resistance, durability, and heat stability than PLA. However, it is more challenging to print with as it requires higher temperatures and often experiences warping. The finished products are commonly used in functional applications such as automotive interiors, electronic housings, and toys.
Filament comes in various diameters, ranging from 1.75 mm to 3 mm. The different filament diameters are mainly down to the type of printer used. However, choosing the right filament type and diameter is crucial in achieving high-quality prints.
In conclusion, filament is an essential component of 3D printing technology, and its various types cater to different print requirements. PLA is suitable for creating objects that require a clean and smooth finish, while ABS offers higher impact resistance and durability. By understanding the science behind filament, 3D printing enthusiasts can create high-quality prints, unlocking limitless possibilities for innovation and creativity.#16#
