Thermal breaks in additive fabrication process to avoid material degradation
The patent application (Publication Number: US20240025117A1) describes an additive fabrication device designed to create three-dimensional objects through sintering a source material. The device includes a chamber with distinct sections and a thermal break made from a different material, a fabrication platform for receiving and layering the source material, a material deposition mechanism, and heaters to heat the deposited material. The thermal break is strategically positioned within the chamber to optimize thermal conductivity and efficiency.
Furthermore, the patent outlines specific details regarding the composition and configuration of the chamber, thermal break, and other components of the additive fabrication device. For instance, the thermal break is made from materials like plastic or ceramic, with Polyetheretherketone (PEEK) being a potential option. The dimensions and positioning of the thermal break within the chamber are also specified to enhance performance. By incorporating these features, the additive fabrication device aims to improve the quality and precision of the three-dimensional objects produced while maintaining operational efficiency.
