Making a Modal Hammer for Tight Spaces

Proto Labs made Stream Lion’s re-engineered modal hammer out of durable nylon materials on an HP Multi Jet Fusion 3D production printer. Stream Lion reports the parts arrived out of the box with precise features that fit the other parts in the assembly properly. Stream Lion image courtesy of Proto Labs Inc.

When the tools for the job proved too cumbersome, this engineer re-engineered his tools and used production-grade 3D printing for the final part.

How to 3D Print High-Strength Workholdings

Markforged's cloud-based 3D print software provides granular control of where to lay reinforcing fibers in a continuous stream in a part under development. Shown here are two fill options. Isotropic fill on the left lays down a sheet of fiber in the part. Internal hole concentric fill on the right encircles internal part cavities. Image courtesy of Markforged Inc.

Tough, stiff and precise 3D printed parts made of composite materials can handle the beating workholdings and fixturings get during machining applications.
