Application Notes  |  


Metal 3D printing has completely changed how we think about manufacturing of metal components. While this has simplified the manufacturing process it also involves some other parameters that need to be considered and tracked to ensure a high quality part.

One such parameter is the density of the part. A part with sub-optimal density part will be brittle and heat treatment is required to prevent that. This heat treatment process is called vacuum sintering is used. In this process, the 3D printed part is placed in a furnace with a very high vacuum and a temperature nearing the melting point of the metal. This point is known as the sintering temperature and it facilitates solid state diffusion of the metal atoms. As the metal atoms diffuse and re-arrange, cavities and imperfections in the parts are eliminated hence making it denser and stronger.
