What are the key steps and influencing factors in 3D printing production?

Steps: First, prepare the 3D model file that needs to be printed.

Like ordinary printers need documents, 3D printing also needs to provide printing files, that is, to prepare a 3D model in STL format, and users can design it themselves or go to a professional **. The 3D model design software that users can use includes: 3dmax, AutoCAD, Maya, SolidWorks, Proe, UG, etc., and needs to be exported into STL format files after the design.

Step 2: Prepare before printing.

Before printing, the 3D printer needs to install the driver and slicing software (such as the Repetier-Host software configured by the Lecai 3D printer), and install the consumables correctly. Then import the STL file of the finished 3D model into the software for slicing and generate G**. Preheat the 3D printer printhead and platform, set the filling rate, printing speed, printing accuracy and other parameters, and wait for printing.

Step 3: Start printing.

Once the printhead and platform temperature are up to the required level, you can print, depending on the performance of your machine, your parameter settings, and the size of the printed model. After the printing is completed, wait for a while for the platform to cool down before taking down the model, and then polish and color the model.

Influencing factors. dThe performance of the printer itself The setting of the parameters of the dPrinter The printing materials used by the dPrinter. 4. The design model.

You can take a look at the 3D printing of the any-and-you type.

3D printing. The main technical difficulties are as follows:

1. The printing accuracy problem, the accuracy of the printed product is not high, and it is generally around plus or minus, and the high-precision requirements cannot be met.

2. The surface effect of the printed product is not ideal, and most of the surface will be rough and need to be polished again.

3. The deformation of the printed product is slightly larger, and the product with large size and small thickness is more likely to be deformed.

4. The printing size is limited, especially in the metal field, and the printing size is generally limited to 350mm.

5. The printing time is long, and the printing time of a plate of products is usually 24-100 hours, which is still too long.

Therefore, equipment manufacturers still have to work hard to improve in the face of the above problems!

Kiss! Hello, happy to answer your <>

What are the main steps in the process planning process of pro-3D printing are as follows: 1. The three-dimensional design is first modeled by computer modeling software, and then the completed three-dimensional model is "partitioned" into layer-by-layer sections, that is, slices, so as to guide the printer to print layer by layer. 2. The slice processing printer prints these sections layer by layer by reading the cross-sectional information in the file, and then glues the layers of sections in various ways to create an entity.

The peculiarity of this technique is that it can create objects of almost any shape. 3. The resolution of the finished printed 3D printer is sufficient for most applications (it may be rough on the curved surface, like the sawtooth on the image), and the higher resolution items can be obtained by the following methods: first use the current 3D printer to hit a slightly larger object, and then slightly polish the surface to obtain a smooth surface "high-resolution" item.

I hope I can help you <>

Do you have any other questions?

1. Three-dimensional design.

The completed 3D model is first modeled by computer modeling software, and then the completed 3D model is "partitioned" into layer-by-layer sections, that is, slices, so as to guide the printer to print layer by layer.

2. Slicing processing.

The printer reads the cross-sectional information in the file, prints these sections layer by layer with liquid, powder, or sheet material, and then glues the layers together in various ways to create a solid. The peculiarity of this technique is that it can create objects of almost any shape.

3. Complete printing.

The resolution of a 3D printer is sufficient for most applications (it can be rough on a curved surface, like a jagged image), and higher resolution items can be achieved by first punching a slightly larger object with the current 3D printer and then slightly sanding the surface to produce a smooth "high-resolution" object.

The three major features of 3D printing are as follows:

1. It can manufacture the shape that cannot be manufactured by traditional production technology.

dPrinting requires no machining or tooling, and parts are generated directly from the computer. Fabricating complex items without increasing costs will break the traditional pricing model and change the way manufacturing costs are calculated.

3. In the case of a good design concept and design process, the technology can also simplify the production and manufacturing process.

The principle of 3D printing

3D printing technology is basically the same as laser forming technology, which simply means that 3D entities are generated by layering processing, superimposing molding, and adding materials layer by layer. It is called a "printer" because of its technical principle, and the layering process of a 3D printer is very similar to that of an inkjet printer.

First of all, the computer is used to design the three-dimensional model of the required parts, and then according to the process requirements, the model is discretized into a series of ordered units according to a certain law, and it is usually discretized according to a certain thickness in the Z direction, and the original three-dimensional CAD model is turned into a series of layers; Then, according to the contour information of each layer, input the noisy processing parameters, and then automatically generate CNC ** after the system; Finally, a series of layers are formed and automatically connected to obtain a three-dimensional physical entity.

The basic process of 3D printing is as follows:

1.Digital design: Use computer-aided design (CAD) or other software to create or acquire a 3D model based on which all future operations will be performed.

2.Choose printing materials: Choose the right 3D printing materials, such as plastics, metals, ceramics, wood, etc.

3.Model slicing: Use 3D printing software to slice the 3D model into layers, and each layer will be printed with a printer.

4.Upload the file: Upload the sliced file to the 3D printer and set the printing parameters, such as printing speed, temperature, material model, etc.

5.Printing: Start the 3D printer and let it perform the printing task automatically. The printer will print according to the preset path and parameters, and accumulate the production model layer by layer.

6.Post-processing: Remove the printed model from the printing platform and complete post-processing such as removing the bracket, grinding and painting.

The above is the basic process of 3D printing, but the actual application may also change according to the needs of the search.

What are some precautions in the process of 3D printing, hello dear, 1Size requirements: When making sure that there are no problems with the model, use the STL format to slice, and pay attention to whether the size of the model meets the requirements when slicing.

2.Model requirements: In the case of no support at the bottom, the bottom of the model that needs to be printed must be able to support the entire model, if the bottom of the model is uneven and the base has only a few contact points, please use the repair software to cut the bottom flat or use the slicing to destroy the hand grip software to sink.

3.Support inspection: remember to check three parts when adding supports: (1) whether the support obstructs the model itself, to prevent the support on the model from being inconvenient to remove when the support is removed; (2) Whether the support in the suspended position is in place to prevent the incomplete model printed without support in the suspended position; (3) whether the support at the bottom of the model can be added in place, prevent the model edge from being printed incompletely, or the model with less support can not be printed;
