Problems solved by technology

However, when using ABS material or other 3D printing materials, the printed object will still have a certain degree of warping on the film layer
In addition, the manufacturing method of this film layer is relatively cumbersome, and the chemical composition needs to be further improved. While improving the versatility of various printing materials, the preparation method should be optimized to better adapt to industrial production

Abstract

Provided is a printing working platform applied to a three-dimensional printer. The printing working platform successively comprises a heating layer, a glass layer and a film layer, wherein the film layer is composed of 12 parts by mass of a heterocyclic acrylic resin and 24 to 28 parts by mass of a weak solvent resin. After the printing is finished, the heating layer stops heating, and then the temperature of the film layer decreases gradually to the room temperature. At this time, the adhesion force between the film layer and the contact surface of a printed object is at the minimum, and a user can easily and conveniently take out the printed object, such that the integrity of the film layer will not be damaged, and the service life of the film layer is increased. This film layer is also applicable to three-dimensional printing materials, such as ABS, nylons (PA) and polycarbonates (PC), and is high in universality.

Description

technical field [0001] The invention relates to a working platform of a three-dimensional printer and a coating and a film layer on the working platform, in particular to a coating, a film layer, a printing working platform and a preparation for improving the adhesion and versatility of a heterocyclic acrylic resin method. Background technique [0002] Three-dimensional (3D) printing technology is a kind of rapid prototyping technology. Its common printing process is: firstly model through computer modeling software, and then "partition" the built three-dimensional model into layer-by-layer sections, that is, slices, so as to guide The printer prints layer by layer. The materials of 3D printers mainly include bondable materials such as powdered metal or plastic. [0003] Rapid prototyping technologies currently on the market are mainly divided into fused lamination modeling (FDM), three-dimensional printing (3DP), stereolithography (SLA), selective laser sintering (SLS), a...
