ADDITIVE MATERIAL EXTRUSION
THE BASIC TECHNOLOGY OF HAGE3D
The basic technology behind HAGE3D is additive material extrusion, an extrusion-based sub-discipline of additive manufacturing. Material extrusion and suitable print heads enable processing of a wide variety of moulding compounds, including granulates and filaments. If processing is based on filaments, the technology is also known as FFF (Fused Filament Fabrication), FDM (Fused Deposition Modelling) or FLM (Fused Layer Modelling). The material is conveyed through a die in a molten state (hot extrusion) or as a paste (cold extrusion) and deposited strand by strand. The process has several benefits when compared to other additive manufacturing technologies:
- Compact process
- Material flexibility
- High print volume
- Multi-extrusion (e.g. hybrid components)
Additive material extrusion can be used to process different materials quickly and cleanly with high accuracy, whether large component or small component. Once printing is complete, the components are ready for use. Cumbersome post-processing, such as powder removal or curing, is no longer needed.
