The 3D printer, also called three-dimensional printer, is a machine of an accumulative manufacturing technology, i.e. a rapid prototyping technology, which is a method for manufacturing a three-dimensional object by printing a layer of adhesive material on a layer by using an adhesive material such as a special wax material, a powdered metal or plastic and the like based on a digital model file. 3D printing is typically achieved using digital technology material printers. The method is often used for manufacturing models in the fields of mold manufacturing, industrial design and the like, and is gradually used for directly manufacturing some products, and parts printed by the technology are already available. The technology has applications in jewelry, footwear, industrial design, construction, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields.
The 3D printer constructs an object by a layer-by-layer printing mode, mainly adopts inverted printing, so that when a product needs to be printed, the plane of a first layer needs to be ensured to be horizontal, and when the plane is not horizontal, the difference value is compensated by recording the distance between a printing head and the plane, and the process is called leveling. The existing leveling modes comprise probe leveling, steering engine leveling, pressure-sensitive leveling and inductance leveling; wherein,
the probe leveling method is characterized in that a microswitch is pressed by an L-shaped small inner hexagonal wrench by hand, penetrates through a printing head fixing platform, a spring below the microswitch is pulled, a probe touches the printing head fixing platform, is lifted upwards, releases the microswitch and transmits trigger information, but the probe leveling method has low accuracy and success rate, and the probe needs to be withdrawn after the leveling is finished, so that the probe leveling is troublesome;
the steering engine leveling method can be used for mounting the microswitch on the steering engine, putting down the microswitch before leveling, and retracting the microswitch after leveling, but the steering engine is additionally arranged at the printing head, so that the structure of the printing head is complicated, and the microswitch is required to be put down and retracted through the steering engine before and after leveling, so that the method is complicated;
the pressure-sensitive leveling method is characterized in that a pressure-sensitive sensor is arranged below a workbench, and a printing head presses the workbench to trigger the pressure-sensitive sensor so as to level, but the pressure-sensitive sensor is influenced by a hot bed and has much higher cost compared with other modes;
the inductance leveling method is used for leveling in a mode of an inductance proximity switch, but the inductance leveling method is large in size, occupies a printing head space, can only act on a metal printing platform and is low in applicability.
