Our dynamic Flow Control system, also known as a gear pump extruder or an extruder with a melt pump, is a positive displacement pump that is used in to provide precise and constant pressure to the melted material as it is extruded from the nozzle. Click to read more about the advantages of the Dynamic Flow Control.
The dynamic Flow Control (DFC) is used to stabilize the pressure of the melted material by providing a constant flow rate. The gear pump consists of two meshing gears that create a sealed chamber between them. As the gears rotate, the chamber fills with melted material, which is then forced out through the outlet at a consistent rate.
The use of a gear pump allows for more precise control of the printing process, resulting in higher quality prints with fewer defects.
Advantages of a melt pump in additive manufacturing include:- Precise control: a DFC can provide precise and consistent pressure to the melted material, which results in a more accurate deposition of the material and better print quality.
- Improved material handling: a dynamic Flow Control can handle a wide range of materials, including those with high viscosity, which can be difficult to handle using extruders that haven't got this option.
- Reduced waste: a gear pump can help reduce material waste by ensuring that the material is deposited in the right place at the right time, resulting in less scrap.
