Support-Free Printing of Closed Impellers

Metal 3D printing without supports has multiple potential benefits, but there are many factors that need to be considered to reduce the supports needed for a successful build.

Fewer supports mean less powder is used to lower costs and improve build times.
Reduced overhang angle limits mean that less supports can be needed for some builds.
Cut down on post-process to manufacture parts more simply and efficiently.

Is support-free 3D metal printing
really possible?

Going completely support-free is the white whale of additive manufacturing (AM) processes. Reducing the size and number of supports for 3D printing projects can have significant implications to the cost, environmental impact and efficiency of your operations.

Not needing to remove supports during post-processing can save time and cost. Avoiding support structures also reduces waste, with only a minimal amount of material removed after the build is complete.

It isn’t a straightforward process, though. The challenge comes with determining how to achieve this without compromising the build. Supports are pivotal to the part’s integrity, providing structural rigidity, heat dissipation and preventing the part from deforming.

Finding ways to overcome each of these individual threats to a build’s success is one thing, but a solution that accounts for all of them requires a great deal of experimentation and experience. We have worked on many bespoke projects where we’ve pushed the boundaries of what’s believed to be possible to come up with creative AM solutions. These specialist projects and the solutions our teams devised have brought us closer than ever to achieving support-free 3D metal printing.

In this whitepaper, Additive Minds team manager Davy Orye and his team have taken the findings of various closed impeller projects to bring you a comprehensive overview of what’s possible if you want to significantly reduce supports in your builds.
