Method and System for Controlling Temperature of Products during 3-Dimensional (3D) Printing

3D printing is a process for making a physical object from a 3D digital model by laying down many successive thin layers of a material. After laying down of each layer of

material, the layers of material come in contact with the surrounding air and environment and a process of heat dissipation is initiated. Each layer of material cools down separately thereby causing uneven cooling. Further uneven cooling creates uneven crystal formation and internal crack or distortion in the final 3D printed product. There is a need for a 3D printing system that controls the uneven cooling pattern of the products during 3D printing.

Disclosed is a method and system for controlling temperature of products during 3D printing. The method and system employs one or more insulation layers (sacrificial or consumable) around the product during fabrication process to control uneven cooling and thereby avoid internal cracks and distortions in the final product.

In accordance with the method and system, the 3D printing system includes an additional nozzle which lays the insulation layers around outer surface of the each layer boundary for reducing heat dissipation. The insulation layer can be printed with materials such as, for example, wax, composite material, polymer, sticky silica power etc. The insulation material are selected based on the material selection for 3D printing. The thickness of...
