This model has an animation. Length of animation is 500 frames. The model has controllers connected to axis. The rotation axis changes the position of a print head 3D printing, also known as additive manufacturing (AM), refers to processes used to synthesize a three-dimensional object] in which successive layers of material are formed under computer control to create an object. Objects can be of almost any shape or geometry and are produced using digital model data from a 3D model or another electronic data source such as an Additive Manufacturing File (AMF) file.
