Leveraging DfAM for enhanced FDM post-printing efficiencies

Additive manufacturing (AM) is a powerful technology that lends itself to producing organic geometries, and building parts in short timeframes.

Additive technologies such as FDM 3D printing are capable of printing shapes that cannot be created by any other means. One of the most salient factors in successfully building these unique designs is the utilization of soluble support material.

As is well-known by anyone who has worked with additive technology, 3D-printed end use parts and prototypes do not come off of the printer “customer-ready.” Virtually every printed part, regardless of print technology, requires some sort of post-printing, whether that be support removal, resin removal, surface finish, or all the above.

This paper will identify the ways in which designing for additive manufacturing (DfAM) can affect efficiencies, cost, and support material usage in Fused Deposition Modeling (FDM) 3D printing. Print orientation, support settings within the slicing software, and part design are all aspects which can be leveraged to streamline additive workflows, and facilitate faster, more cost-effective post-printing.
