With the integrated ViscoTec technology the 3D printer builds up the object layer by layer, by juxtaposing and superposing lines of adhesive beads. The core element of each application is a volumetric dispensing pump based on the endless piston principle which belongs to the group of rotary positive displacement pumps. This volumetric dispensing pump is a well-established product from ViscoTec.
This process is suitable for all fluids ranging from low to high viscosities, up to just over two million mPas. It even remains fully functional with grainy or fibrous solids. 3D printed silicones can replace complex injection molded parts, two-component glues based on polyurethane or epoxide can be used for parts with high tensile and compressive strength and allow high chemical and temperature resistances or composite-materials that combine different properties: The application area of the FDD printhead “made in Germany” is very diverse.
