There are various manufacturing constraints in AM that can be incorporated into the design optimization process and it is the incorporation of these into the topology optimization process which will create designs ready for production .
 concept or principle: manufacturing constraints; manufacturing process: AM; material: be; concept or principle: design optimization process; engineering feature: topology optimization process; engineering feature: designs; manufacturing process: production
