Video: Programming for Additive Turning of Cylindrical Parts

By: Peter Zelinski

Directed energy deposition while the part is spinning enables a means of 3D printing axially symmetric parts. The operation is like CNC turning with material added instead of machined. Open Mind discusses programming the machine paths for this type of build.

Additive Manufacturing Creates New Paths to Production

By: Peter Zelinski

On the journey from product idea to production, when does the “mold moment” come? That is, the moment of needing to invest in tooling and make design commitments. 3D printing can delay this step on the journey or even avoid it altogether.
