An automatic removal method for 3D printing models

Abstract

The invention discloses an automatic removing method for a 3D printing model. A platform of a 3D printer is heated, and hot melt adhesives are melted and evenly pasted on a hot bed; before printing, a hot bed plate is cooled to the temperature lower than the softening temperature of the hot melt adhesives; normal model printing is carried out; the platform is heated to the temperature exceeding the softening temperature of the hot melt adhesives, and the temperature of a head waiting to extrude is decreased to be below the softening temperature of a model; when model printing is finished, a motor model on an X shaft and the platform on a Y shaft are moved to the side, the extrusion head is automatically moved to a corner, then a Z shaft is descended, and the extrusion head or an X moving guide rail touches the model through the movement of the X moving guide rail and a Y moving guide rail; by moving the X shaft and the Y shaft, the extrusion head or the X shaft scans the platform of the hot bed in a full-range mode, then the model is pushed off the platform of the hot bed, and automatic removal is completed. The automatic removing method for the 3D printing model can realize automatic and circulating printing without manual interference, 3D printing operation is simpler and more intelligent, and a large amount of printing time is saved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for automatically removing a 3D printing model. Background technique [0002] The 3D printers currently on the market do not have an automatic removal function. Usually, textured paper or solid glue is pasted on the bottom plate before printing, so that the model can stick to the bottom plate, so that the model will not be damaged during printing. It is easy to move and is not easy to warp. After the printing is completed, the general method is to shovel the model with a shovel. This operation method means that if you want to print a new model, you must first take the model manually, and usually in After the model is printed, it may take a long time until the user finds that the model has been completed, and the user may be interrupted by the printer at any time. For customers who need to print in batches, usually they can only print during the day, and at night beca...

[0002] The 3D printers currently on the market do not have an automatic removal function. Usually, textured paper or solid glue is pasted on the bottom plate before printing, so that the model can stick to the bottom plate, so that the model will not be damaged during printing. It is mobile and not easy to warp. After the printing is completed, the general method is to shovel the model with a shovel. This method of operation means that if you want to print a new model, you must first take the model manually, and usually in After the model is printed, it may take a long time until the user finds that the model has been completed, and the user may be interrupted by the printer at any time. For customers who need to print in batches, usually they can only print during the day, and at night because of no one guards and can only be wasted
