Things to know about Fused Deposition Modeling

What is Fused Deposition Modeling?

Fused Deposition Modeling (FDM) is a 3D printing process that constructs objects layer by layer from the bottom up by heating and extruding thermoplastic filaments. The technology, developed in the late 20th century, is distinguished by its use of a continuous filament of a thermoplastic material. This filament is fed through a heated moving head that melts and extrudes it to form each layer of the object based on the digital model's instructions. FDM has made a significant impact in various industries, including manufacturing, aerospace, and healthcare, by enabling the rapid prototyping and production of complex, high-strength parts with a high degree of customization and minimal waste. Its versatility and ease of use have democratized access to 3D printing technologies, fostering innovation and reducing time-to-market for new products. Additionally, by allowing for the direct manufacturing of parts with complex geometries that would be difficult or impossible to achieve through traditional subtractive manufacturing methods, FDM has contributed to advancements in design and engineering practices. The technology’s capability to utilize a wide range of thermoplastic materials, from standard acrylonitrile butadiene styrene (ABS) to advanced composites, further expands its applications across different sectors.
