3d printing device with spectrum converter for sintering molded parts
The patent application (Publication Number: US20240025118A1) describes a device for producing 3D molded parts using a powder-based printing process. The device includes a construction platform, a coater for applying construction material, a print head for selectively applying an absorber, and a sintering unit with radiators and a radiation filter. The sintering unit passes over the construction platform after the absorber is applied, ensuring precise temperature control for sintering.
Furthermore, the patent application details a method for manufacturing molded parts using the described device. The method involves applying particulate material, heating it to a base temperature, selectively printing the absorber, and then sintering the material with controlled temperature variations. The method includes adjusting radiator power, controlling heating through radiator speed, and utilizing different spectra for sintering units. This innovative approach eliminates the need for a stationary overhead radiator, enhancing efficiency and precision in the 3D printing process.
