1: multi-head spraying: resin, wax and other materials are generally used, and molding materials and supporting materials are sprayed during printing. For plastic and dental equipment types, the support material is wax.

2. Laser melting: Commonly used materials are titanium alloy, cobalt-chromium alloy, stainless steel and aluminum alloy, and metal powder is made by high-energy ytterbium fiber laser melting.

3. Laser sintering: commonly used materials are nylon, metal powder, ps powder and resin sand, and the powders are closely combined through sintering.

4. Light curing rapid prototyping: photosensitive resin is usually used to focus the cured material surface on the surface through specific wavelength and intensity, and the model is printed by point-to-line printing.

5. Melt deposition: the representative product is vertical cube Mega X, and the commonly used printing materials are polylactic acid and ABS plastic. In this method, filamentous materials such as thermoplastic, wax or metal are extruded from a heating nozzle, and the model is printed according to the predetermined trajectory of each layer of the part.

Step 1: Create a model.

Want to play 3D printing, the most important and essential link is modeling! At present, there are many softwares that can draw 3D graphics. The key is to see if it can generate stl format files. Commonly used 3D drawing software such as AutoCAD, 3Dsmax and solidworks can be exported or converted into STL format.

Step 2: Add Model

Slicing software is a kind of 3D software, which can convert a digital 3D model into a printing code that can be recognized by a 3D printer, so that the 3D printer can start executing printing commands. 3D printers usually come with slicing software. On the main menu page, there is usually an option of "Add Model". After clicking, the model we created or downloaded will automatically appear in our 3D printing space.

Step 3: Select layered slices.

The correct setting of 3D printing slicing software will effectively improve the success rate of 3D printer printing model. In the main menu, there is usually an option of "Layered Slice". This function is mainly to help us decompose the printing process of the printer, and users can preview and observe the whole printing process in advance in the software. After clicking, you can see that some changes have taken place in the model.

Step 4: Drag the rating preview scroll bar.

Drag the layer preview scroll bar, and the software can display the images of each layer according to the parameter values. We know the principle of FDM printing technology. In fact, the whole model is made of materials stacked layer by layer. By previewing, you can intuitively observe how the model is generated layer by layer.

Step 5: Add Support

Some important parts of some models need to be supported. Like the horns of an elk. At this time, we can add a support to the appropriate part of the model, so that the printer will also print this part of the support when printing, and we can remove the support in some ways later. Some supports are water-soluble materials, which can be easily removed later.

Slicing software generally supports manual support and automatic support. Automatically add brackets, and the system will automatically judge to add brackets in some parts according to the model you want to print.

Step 6: Connect the printer.

Select Connect Printer to connect the computer to the printer.

Step 7: Start printing.

Before starting printing, you need to check the model information again to ensure that the parameters of the model are correct. Click the main menu to select model information. The second is to ensure that the model does not exceed the printing range of the model itself. Finally, we need to set the temperature of the print head and printing platform.

Step 8: Model post-processing.

After the model is printed, if it is not integrally formed, we have to polish and assemble the model to form the finished product.
