How does 3D printing work?
- Creating a 3D model: Using computer-aided design (CAD) software, a designer creates a 3D digital model of the object to be printed.
- Slicing the model: The 3D model is sliced into thin layers by a software called a slicer. This software generates instructions for the 3D printer on how to build the object layer by layer.
- Preparing the printer: The 3D printer is loaded with the material to be printed, typically a thermoplastic filament or liquid resin. The print bed is heated to the appropriate temperature.
- Printing: The printer follows the instructions from the slicer and deposits the material onto the print bed, building up the object layer by layer. This process can take several hours to days, depending on the size and complexity of the object.
- Post-processing: Once the printing is complete, the object may require post-processing, such as removing support structures, sanding, or polishing, to achieve the desired finish.
