The technique builds layers horizontally and stacks them vertically to create parts. Direct energy deposition employs a laser, electron beam, or electric arc to fuse wire or powder material.Binder jetting prints 3D metal, full-color prototypes, and large-scale ceramic molds. Binder jetting deposits a thin layer of powdered material, such as metal, polymer sand, or ceramic, onto the build platform, after which a print head drops adhesives that bind the particles.All 3D printing techniques fit under one of the following categories. The international organization for standardization (ISO)classifies three-dimensional printing technologies into seven classes. The power supply unit (PSU) supplies power to all other components of the printer.

They help the printer hold its axis and avoid derailments. End stops tell the printer its position and prevent it from exceeding the allowable limits.The stepper motor is coupled to the drive gears via belts that fit over the gears and allow them to move smoothly with the motor. Belts are another motion component of the 3D printer.They also help move other components like the printer head, bed, rods, and screws. Stepper motors within a 3D printer aid in the construction of an object in several little steps.
