3D printing techologies
All 3D printing technologies are based on the same principle, which involves gradually layering material on top of each other. However, even in the present day, there is no universal method suitable for all applications. It is necessary to consider what we expect from the printer and what we want to print. The most well-known 3D printing technologies can be divided into three categories based on the form of material printing and its processing:
- Material in the form of filament – material is extruded through a heated nozzle, including FDM and FFF. These can be considered synonymous.
- Liquid material – each layer is cured by a light beam (UV or DLP). This category includes SLA.
- Material in the form of fine powder – material is fused using a laser. Representative technologies include SLS.
1. FDM/FFF
1.3. Polar
The least used system of printers. The movement is based on a print head that moves on two axes and a rotating build platform. The printer is simple in construction, but the execution and preparation of a model for printing are relatively complicated.
