Abstract Scope |
Laser-based powder bed fusion processes like selective laser melting are one of the additive manufacturing (AM) processes that produce 3-D metal parts from CAD data. Until now, only conventional alloys like the AlSi10Mg, 316L, etc. that either is developed for cast or wrought processes have been used for fabrication. Some of the alloys work well for the AM process like the Al12Si, AlSi10Mg because they have good fluidity and are readily weldable. Nevertheless, most of the materials fabricated by SLM show superior mechanical properties. Even though superior mechanical properties were recorded, there are reports showing the premature failure of the materials (i.e.) the material fail before they achieve their maximum strength. Some of the reasons behind this premature failure will be discussed in detail. |
