Description

Automatic lifting platform of 3D printer

Technical Field

The utility model belongs to the technical field of the 3D printer, concretely relates to 3D printer automatic rising platform.

Background

Using the printer as if printing a letter, by tapping the "print" button on the computer screen, a digital document is transferred to an ink jet printer which sprays a layer of ink onto the surface of the paper to form a two-dimensional image. In 3D printing, the software performs a series of digital slices through Computer Aided Design (CAD) and transmits the information on these slices to a 3D printer which stacks successive thin layers until a solid object is formed. The 3D printer differs from the traditional printer in that the "ink" it uses is a real raw material.

The form of the stacked thin layers is various. Some 3D printers use an "inkjet" approach. For example, an israel 3D printer company, named Objet, uses a printer head to spray a very thin layer of liquid plastic material onto a mold tray, and this coating is then subjected to uv light. The mold tray is then lowered a minimal distance for the next layer to be stacked. Another Stratasys company, headquartered in minneapolis, usa, uses a technique called "melt-deposition molding" in which the entire process is to melt the plastic in a nozzle and then form a thin layer by depositing plastic fibers, which requires a simple, automated control and stable drive of the lifting platform device of the 3D printer.
