How does 3d printing work?

Answer 1

Think of a 3D printer as a downward pointing glue gun with plastic filament instead of the glue tube. The beginning of the 3D printing process starts on the computer. A 3D file is created on a computer using CAD (computer aided drafting) software. The file is then converted to a 3d printer-friendly format in order to be printed. This is accomplished by taking the 3d object from the CAD file and slicing it horizontally into many thin layers. Once the file is sent to the 3D printer to be printed, the 3D printers start with the first layer of the object (usually 0.1 mm tall). Once the first layer is completed it moves up to the next layer (again, usually about 0.1 mm) and prints the next layer. The 3D printer will repeat the process until all layers are printed and the object is complete. You will get more information from iannone3d.com.

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. It all starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object. . If you want more information about 3d printing, visit: iannone3d.com
