ABSTRACT |
|
|
|
The use of additive manufacturing has
gripped the manufacturing market. The technology which was only
restricted to prototyping has now pushed its boundary by being cost
effective and rendering endless capability to convert any complex
design into tangible outputs. In this paper, a real-time automotive
steering mechanism part named “Holder” is produced by investment
casting. The customary practice of using a wax pattern in investment
casting has been replaced by 3D-printed patterns of polylactic acid
[PLA]. “NX” software has been used to design the castings due to its
simple synchronous modeling options and “Altair Inspire Cast Student
version 2019” has been used for simulation of casting defects and
analyzing effective filling. The results focus on choice of
effective filling system and effectiveness of 3D-printed PLA
patterns in investment casting. This study encourages implementation
of additive manufacturing for small volume production in investment
casting. |
