What is FDM Printing
Fused Deposition Modeling (FDM), also known as Fused Filament Fabrication (FFF), is one of the most common and accessible 3D printing technologies. It creates three-dimensional objects by depositing thermoplastic material layer by layer.
How It Works
- Filament Feeding: A thermoplastic filament is fed into the 3D printer from a spool.
- Material Melting: The filament passes through a heated extruder, where it melts.
- Layer Deposition: The melted material is extruded through a nozzle and deposited onto a build platform. It solidifies as it cools.
- Layer-by-Layer Construction: The object is built from the bottom up, following the design of a digital 3D model, usually in formats like STL or G-code.
Common Materials Used in FDM
PLA (Polylactic Acid) is one of the most commonly used thermoplastics in 3D printing, particularly in FDM/FFF printers. It is favored for its ease of use, environmental friendliness, and versatility. Ideal for prototyping, decorative items and educational projects. However due to it’s low heat resistance, it’s not recommended for high temperature applications or prolonged outdoor use.
ABS (Acrylonitrile Butadiene Styrene) is a durable and versatile thermoplastic commonly used in 3D printing, particularly for functional and mechanical parts. It is known for its toughness and heat resistance, making it a popular choice in industries like automotive, electronics, and consumer goods.
TPU (Thermoplastic Polyurethane) is a highly flexible and elastic material used in 3D printing. It combines the durability of plastic with the elasticity of rubber, making it ideal for applications that require flexibility, impact resistance, and resilience.
