What is fused deposition modeling?2 answersFused deposition modeling (FDM) is an additive manufacturing process that involves depositing successive layers of material to create a three-dimensional object. It is a popular and widely used technique for three-dimensional prototyping due to its cost-effectiveness, convenience, and environmental friendliness. FDM is based on the additive principle, where digital three-dimensional design data is used to build up a component layer by layer by depositing material. This process eliminates the need for expensive tooling and allows for flexibility in part fabrication, making it advantageous for advanced manufacturing industries. However, the quality of FDM prototypes is sensitive to process parameter variation, and the performance of the product is highly dependent on these parameters.
