Binder Jetting technology is putting a lot of attention to debinding systems as well as to perfecting process parameters in particular in terms of temperature uniformity. Both aspects have key influence on final piece quality and performance.
Laser sintering technology enables printing items made of materials such as alloy steels, aluminium and titanium. Heat treatment of such details requires oxygen-free environment. Thus, parameters such as leak rate and vacuum level are a key for SECO/WARWICK additive manufacturing furnaces.
These are the key parameters that help to achieve the required molecular structure and pureness level of parts.
Heat treatment process performed in controlled furnace conditions helps to achieve required parameters of printed pieces. Highly demanding sectors like aerospace, medical or automotive have specific needs in this area and furnace needs to satisfy them.
