The invention relates to the technical field of 3D biological printers, in particular to a printer support based on electromagnetic suspension and a 3D biological printer. The printer support based onelectromagnetic suspension specifically comprises a first-level suspension support and a second-level suspension support, wherein the first-level suspension support and the second-level suspension support are respectively operated in five degrees of freedom, ten degrees of freedom directions are formed up and down to form control force, and two degrees of freedom directions perpendicular to eachother are taken as feeding directions; and the other eight degrees of freedom directions serve as angle change directions. According to the printer support based on electromagnetic suspension, magnetic suspension is adopted to replace a traditional mechanical structure, errors caused by mechanical motion and friction can be eliminated, printing motion and control precision are improved, and the magnetic suspension is more suitable for precise tasks such as 3D biological printing; and meanwhile, structural loss is reduced, frequent maintenance and trimming of mechanical structures are not needed, and the overall service life of the 3D biological printer is prolonged.
Description
technical field [0001] The present invention relates to the technical field of 3D bioprinters, in particular to a moving bracket structure of a 3D bioprinter, specifically a printer bracket based on electromagnetic levitation and a 3D bioprinter. Background technique [0002] 3D printing, known as "one of the important symbols of the third industrial revolution", is rapidly developing into a popular research technology in biomedical engineering, and its related research has set off a new round of research boom at home and abroad. At present, the 3D bioprinting motion platform mainly uses traditional mechanical methods, that is, rigid contact support and "rotary motor + ball screw" drive positioning. This method will reduce the positioning accuracy and response frequency of the equipment due to friction, wear, mass inertia of the driving parts and the gap between the connecting parts. In addition, in the case where multi-degree-of-freedom motion control is required, if guide ...
