3D printing has become a widely popular technology, ranging from printing guns to inflatable dolls, and everything in between. People often come to me asking about Xiaobian, but today, as a responsible young person, I want to explain the entire process of creating a 3D printed product. This will help you understand which industries truly benefit from this technology, and which ones might just be "seeing the excitement" without real value. In my next post, I’ll go into more detail about each step of the 3D printing process, making it even clearer for everyone.
Although 3D printing may seem like a modern innovation, it actually dates back to the 1980s. It was originally developed as a rapid prototyping technique. Using digital model files, 3D printing works by layering powdered metal, plastic, or adhesive materials to create physical objects—this is also known as additive manufacturing. But how exactly does this “printing†method work? Generally, it involves three main steps:
First, pre-model design. Just like traditional printing, you need a material. However, in 3D printing, the most crucial step is the initial design. This determines whether your final product is proportional, free of defects, and matches your vision. The pre-design serves as the data source for the 3D printer. In other words, it's like a blueprint. Without a proper data source, you can't print anything. There are three common ways to get that data:
1. Designing a 3D model using CAD software.
2. Scanning a physical object with a 3D scanner and then modifying it using 3D CAD software.
3. Downloading pre-designed models from online platforms such as 3D forums, 3D websites, or major CAD software communities.
Since the standard file format used in 3D printing is the STL file, using 3D CAD software ensures accurate data. Therefore, it's essential to use a CAD program that can export STL files—otherwise, you may run into formatting issues.
Next comes the actual printing process. Once you have a 3D printer and the right materials, you can transfer the STL file via an SD card or USB drive. The printer’s built-in system will handle calculations for size, weight, and other parameters, guiding the printer through the entire process.
Finally, post-processing. Depending on the material and desired finish, some basic cleaning or finishing may be required. After that, you can finally enjoy your creation, brought to life from your own design concept.
