Using Structural Density Gradients to Optimize the Strength-to-Weight Ratios of 3D Printed Parts

Sustainability icon, disabled. A green leaf.
In order to optimize the strength and weight of an object undergoing additive manufacturing, it is necessary to give the object an appropriate internal inlay structure; however, traditional inlays distribute material inefficiently, in order to make the inlay fit any part. Researching an inlay that can create an adapted density gradient within a part allows for material to be used more efficiently. In order to do this, various configurations of a semi-triangular and semi-hexagonal inlay have been simulated, tested, and compared to control inlays. Successfully optimizing the inlay will provide major advantages to a part’s strength to weight ratio.
