Topology optimization for injection molded parts

[ashivu123]

We are planning to convert injection molded parts to 3D printing parts. Injection molded parts thin (.04" thk) and have some parts loading condition. How to do topology optimization for injection molded parts?

 

[FEA way]

It depends which software you want to use but generally speaking the optimization process will be pretty much the same as for other parts, except for the fact that you may have to introduce some special manufacturing constraimts.

We used Inspire software and results are same as original part. Since parts are thin like .1 inches retaining material only where constrains are given.

The real issue is deciding how much redundancy you want. I have seen printed parts where the failure of one 'strut' causes the part to fail. Remember that printed parts have fairly high flaw levels and some degree of over design and redundancy will be needed. And often stiffness is more critical than strength.
There are many software packages just for 3D topology work, find one compatible with your prefered file structure.

P.E. Metallurgy, consulting work welcomed

You may not know, but Euler, the column buckling guy was the one that opened up the area of mathematics dealing with spaces, ie. topology... and introduced the idea of simply and multiply connected surfaces.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?
