Liquid Deposition Modeling (LDM), also known as Paste Extrusion, is a 3D printing technique that involves extruding specially prepared viscous pastes and slurries (such as clay, porcelain, stoneware, or refractory cements) layer by layer through a nozzle. This method is commonly used for ceramic art, functional pottery, architectural models, and various material research applications. Most LDM printers utilize either air pressure or a screw/auger system for controlled material flow.
