CT Scanning Reveals What Isn’t There in 3D Printed Parts

3D Engineering Solutions offers CT scanning as a powerful nondestructive testing (NDT) solution for inspection. For 3D printed parts, sometimes revealing the space inside can be just as valuable as mapping what was printed.

The Results Are In: Autoclave Tooling and Large Format Additive Manufacturing

SABIC and the University of Dayton Research Institute studied large-format additive manufacturing (LFAM) for metal autoclave tooling. The results are promising.

Video: Metal AM Affects Plastics Production via Conformal Cooling

Additive manufacturing allows cooling channels within mold tooling inserts to follow the form of the tool rather than being straight drilled holes. Here’s why this matters.

Video: The Impact of Part Orientation on Cost and Build Time in AM

A different build orientation might mean fewer layers and less support structure, though the part might need to be redesigned to take advantage of this different orientation.

Why Robots and Additive Manufacturing Go Together

3D printing and robots enable one another. We miss the possibilities of one if we do not consider the other. The combination includes AM for end effectors, robots for 3D printing parts, and different modes of metal and plastic production.

Video: How Simulation Assists Directed Energy Deposition

Scrapping an AM part is potentially as costly as scrapping a machined part. Directed energy deposition is an additive process that can benefit from a resource that safeguards machining: simulation software.
