... with ease. Because the layer-wise shaping during binder jet printing occurs at low temperatures, the layer-wise effect is insignificant compared with that of the previously mentioned processes. Further, because thermal fusing occurs in a sintering furnace and printed objects are heated more or less...

... within the tube provides the driving force for heat transfer at any point. The design of a steam-generating unit balances the heat input from the combustion of a fossil fuel with the formation and superheating of steam. Within the furnace, flame temperatures may approach 1650 °C (3000 °F). Heat...
