Metal Additive Manufacturing (AM) is a process of building metal parts layer by layer using a 3D printer. This technology has the potential to replace traditional machined and grinded parts, as well as bring new possibilities in metal engineering for a variety of industries.
One of the main advantages of metal AM is its ability to create complex geometries and shapes that would be difficult or impossible to achieve using conventional manufacturing methods. This opens up new opportunities in industries such as aerospace, medical, and automotive where unique and highly specialized parts are required.
Additionally, metal AM offers faster production times, reduced waste, and lower costs compared to traditional manufacturing methods. This makes it ideal for small-batch production and prototyping, where quick turnaround and cost-effectiveness are essential.
Finally, metal AM allows for customization and personalization of parts, which is particularly relevant in the medical and dental industries where bespoke implants and prosthetics can be manufactured to meet the exact specifications of each patient.
Metal AM has the potential to revolutionize the way metal parts are manufactured and bring new possibilities in metal engineering across various industries.
Debinding and sintering are crucial steps in the process of metal additive manufacturing (AM).
Debinding is the process of removing the temporary binder that holds the metal powder together in the AM process. This binder is needed during the printing process to ensure the stability and accuracy of the printed part. However, once the printing is complete, the binder must be removed to prepare the part for the final manufacturing steps.
Sintering is the process of heating the metal powder to its melting point, causing the particles to fuse together and form a solid metal part. During sintering, the metal powder undergoes a phase transition from a loose powder to a solid, dense metal part. Sintering is a crucial step in the AM process because it determines the final mechanical properties, such as strength and density, of the finished part.
Debinding and sintering are usually performed in specialized furnaces designed specifically for these processes(HTK Serie). These furnaces must be able to maintain very precise temperature and atmosphere controls to ensure that the parts are manufactured to the highest quality standards. The furnaces must also be able to handle the high temperatures and corrosive environments that are required for these proceses.The inner chamber can be made from metal,graphite or ceramic and permit high purity of inert atmosphere( protective gases like Nitrogen/Argon, and reactive gases like Hydrogen and Carbon Monoxide) and high vacuum in the region of (5 x 10-6 mbar),and maximum temperature 2200 °C and 1600 °C.
