DefinitionA 3D printer (3Dプリンター) is an output device that builds a solid object by forming material into thin layers and stacking them, based on 3D shape data.
ExplanationIt splits shape data made with tools such as 3D CAD (3次元CAD) into thin slices and builds the form by stacking material such as resin one layer at a time from the bottom. Without making a mold, it can produce prototypes or one-off parts in a short time.
AnalogyIt is like cutting cardboard along a map's contour lines and gluing the pieces on top of one another from the bottom to build a model mountain.
Memory hook3D means width, depth and height. Tell it apart by the name: a paper printer with height added.
