Blackbelt, the first 3D printer using a conveyer belt

The Dutch startup Blackbelt 3D unveiled its new 3D printer that incorporates a conveyer belt, allowing for the printing of long or potentially, objects of unlimited length. With an innovation of this kind, it may be bringing a change to FDM printers as we know them, bringing us a “new type of industrial production machine” and possibly changing how we print forever.

Thanks to the conveyor belt, which acts as the Z-axis and the printer’s print platform which moves horizontally, this Dutch printer has the ability to create very long parts as well as the ability to print one part right after another without stopping. At the end of the belt is a tray that collects the prints once they are finished. This means that the printer can operate without the need of someone aiding in the process.

Using a belt that is made of a “carefully selected and well tested” carbon fiber composite, the material is able to adhere properly to the surface, allowing for clean prints. By printing on a 45° angle, the printer removes the need for support structures in many printing instances, helping to save time and building material.
