About 3D printing
3D priting
3D printing is an additive technology for creating objects. It involves the gradual addition of melted material in horizontal layers onto a substrate. This is the opposite process to the one, where material is gradually removed using tools. Although the specific printing methods can differ from each other, the deposition of material remains a common aspect. Therefore, a 3D model needs to be sliced into thin layers in software before the actual printing process.
As a general rule, the thinner deposited layers the more precise and higher-quality model. However, the hardware itself has its limits in terms of how thin a layer it can create. Even if it could produce very thin layers, we would spend a lot of time in the software that slices the model into those designated layers. This would also extend the printing time, as it would take longer to apply each layer and a larger number of layers would need to be created.
