What does FDM mean in PHYSICS

FDM stands for Fused Deposition Modeling, which is an additive manufacturing process that utilizes thermoplastic filament to build 3D objects from the ground up, layer-by-layer. It can be used to create anything from small parts and models to large end-use products like furniture and appliances.

Common materials used in FDM printing include PLA, ABS, PETG and nylon as well as composites like carbon fiber or wood filaments. Each material has its own properties so it's important to choose the right material for your project.

The accuracy of an object produced using an FDM printer depends on a variety of factors including the layer resolution setting and type of materials used. Generally speaking, standard resolution prints have a minimum layer thickness of 0.2mm and can achieve resolutions up to 0.1mm with higher quality prints.

Yes, most 3D printed parts created with an FDM machine require some form of post processing. This could involve sanding down any overhangs or removing support structures from the print if they were used during printing.

Most plastics used for 3D printing are petroleum based but there are also renewable bioplastics available like PLA and Biodegradable PHA which are derived from plant-based sources like corn starch or sugar cane extractions instead of traditional fossil fuels.
