Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

Referring to fig. 1, an embodiment of the present invention provides a 3D printing method for a concealed architectural ornament, where the 3D printing method includes a sample determining step, a dividing step, a scanning step, a modeling step, a printing step, and a finishing step.

The specific content of each step is as follows:

Dividing the sample to be printed into at least two areas to be scanned, wherein the dividing step is positioned before the scanning step; in the scanning step, different areas to be scanned are scanned simultaneously.

In the dividing step, two adjacent areas to be scanned are partially overlapped.

In the modeling step, different areas to be scanned are modeled respectively to form a plurality of subarea models, and the overlapping positions of the different subarea models are processed, so that the overlapping parts of the different subarea models are completely overlapped to form an integral model.

In the printing step, the articles in the printing process are divided into a finished area and an area to be finished, and hot air is blown to the finished area, wherein the finished area finishes all printing processes, and the area to be finished needs to be printed continuously.

Before printing, or during printing, various technical processes are carried out until the printing quality meets various technical requirements. Although 3D technology equipment is capable of producing high quality decorations, it has to be said that the layer-by-layer deposited texture on the printed sample is visible to the naked eye, which often affects the user's judgment, especially when the appearance is an important factor of the product.

In the finishing step, the polishing treatment of the printed article may be performed in one or more of the following ways:

first, a printed article is subjected to a sanding process. Sanding may be by hand or using a specialized machine such as a belt sander. Sanding is a cheap and effective method, and is always the most common and wide-range technology for post polishing of 3D printing parts.

Secondly, the printed matter is subjected to pearl treatment. The second most commonly used post-treatment process is bead-blasting. The operator holds the nozzle to spray the medium beads towards the polishing object at high speed so as to achieve the polishing effect. The pearl treatment is generally fast, the treatment can be completed within about 5-10 minutes, and the surface of the treated product is smooth and has uniform matte effect. The pearl treatment is flexible and can be used for most 3D printing materials. It can be used in various stages from product development to manufacturing, from prototype design to production. The media sprayed for bead blasting is typically very small plastic particles, typically finely ground thermoplastic particles.

Third, the printed article was immersed in a steam pot and the surface of the printed article was melted by steam for 2 microns. The 3D printed part is immersed in a vapor canister with liquid at the bottom that has reached boiling point. The steam rising can melt a layer of about 2 microns on the surface of the part, and the part can become smooth and shiny in a few seconds.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
