| description | Metal additive manufacturing (AM) technologies have attracted a lot of interests from
many industrial sectors due to its unlimited capability of producing complex geometries. Metal parts
with complex shapes at large scales are highly demanded in marine and offshore (M&O) industries.
The aim of this paper is to ascertain the feasibility of Additive Manufacturing (to be more specific
Laser Engineered Net Shaping) of ASTM A131 EH 36 steel. After doing mechanical testing for LENS
processed ASTM A131 EH 36 samples, the LENS processed samples with horizontal build direction
have much better mechanical properties comparing with conventionally made parts, however samples with vertical build direction or 45 degree vertical build directions have properties comparable or lower than parts made of conventional methods due to build defects. |
