is sintering a melting or smelting process

How is Tungsten Carbide Formed? Chronicle

Aug 13, 2015Tungsten has the highest melting point of all metals, at 3410 o C (6170 o F). In order to create parts made from tungsten or tungsten alloys like tungsten carbide, the typical process of melting and blending of the metal and alloying elements is cost prohibitive.

Lead smelting Wikipedia

Lead smelting. Lead is usually smelted in a blast furnace, using the lead sinter produced in the sintering process and coke to provide the heat source. As melting occurs, several layers form in the furnace. A combination of molten lead and slag sinks to the bottom of the furnace, with a layer of the lightest elements referred to as speiss,

And with sintering, the porosity of the material can be controlled. Selective Laser Melting, on the other hand, can do the same as sintering--and go one further, by using the laser to achieve a full melt. Meaning the powder is not merely fused together, but is actually melted into a homogenous part.

SLM works on the principle of melting. The working is same as SLS where as the power is melted instead of sintering. Melting actually creates a pool where the materials can consolidate before reforming and hardening to create new solid structure. The final part won't be porous, thereby making it suitable for a greater range of applications.
