3D Printing is also called additive manufacturing. It is a general technology that uses powdered metal or non-metal adhesive materials to construct objects based on digital model files by printing layer by layer. The 3D printer will slice the digital model, and then let the print head repeatedly lay the material on the printing plate according to the preset trajectory and merge the continuous material layers until the final three-dimensional model is formed. Fusion deposition technology (FDM, Fuse Deposition Modeling) and light curing technology (SLA, Stereolithography) are currently the two most common 3D printing technologies on the market. Because the two technologies have a long history of development, whether professionals or amateurs, they generally use these two technologies as entry options when they come into contact with 3D printers, so they are also the most mature of the current 3D printing technologies. Whether it is for prototyping, model display or general parts manufacturing, although both can print relatively similar parts for users, how to choose the most suitable 3D process and materials in the actual production process is still necessary Pay attention to many details. Let's compare the advantages and disadvantages of these two processes and under what circumstances they should be used. The working principle of the 3D printer of FDM technology is to extrude the molten thermoplastic onto the 3D printing platform, and lay it layer by layer in a layer-by-layer manner until the final 3D model is formed. There are many types of 3D printer materials using FDM technology, from the more common ABS, PLA to composite materials doped with a variety of enhanced powders, making the application fields of FDM 3D printers very wide. At the same time, due to the open source of FDM technology, enthusiasts can also customize the 3D printer, so that printing settings and hardware accessories can be changed according to different needs to meet the needs of more specialized scenarios. The SLA technology 3D printer uses a UV laser or light projector to continuously track each slice layer of the object, and cure the photosensitive resin layer into a hardened plastic until the final 3D model is formed.

The FAQ of FDM 3D printing

3d printing as a new kind of machining method, the scope of application is more and more widely, 3d printing is the need of 3 d model file, many designers design the format of the 3 d model there are many, but in the end all need to the STL format, in the process of transfer format, turns out there is something wrong with the model, could not reach the requirements of 3 d printing, at this time of the model need to be repaired, Then there are problems with 3D printing model design. What are the common repair methods? Please check the following contents:

Describing the FDM 3D Printer's development and for large-size

Nowadays large FDM 3D printing company uses carbon fiber materials to print carbon fiber tables and chairs. The black carbon fiber prints the furniture, which is stylish and elegant. The strength, chemical stability, and abrasion resistance of carbon fiber are very good, and the prints have a rough feel. 3D printing furniture, tables and chairs, provides designers with unlimited imagination space, let's introduce to everyone below.

Designing 3D models for 3D printing is sometimes annoying, because the 3D models used for 3D printing do not have a completely unified standard. Different modeling software, different printing materials, and different printer models even mean completely different 3D printing technologies, which will reflect the different requirements for 3D models. So as a 3D designer, if you find it difficult to design a useful 3D printed model, it is simply too normal. Here, I briefly summarized several problems that are prone to occur in the process of converting 3D models into real objects.
