Jabil Prepares for Production AM: It’s Down to the Basics Now

By: Peter Zelinski

Jabil is getting ready for additive manufacturing to take its place as a production option in addition to conventional processes such as molding and machining. AM can and will fill this role, the company says — the focus now is on controlling cost and assuring quality and reliability.

Video: Controlled Porosity Can Be Functional Advantage Realized via 3D Printing

By: Peter Zelinski

A wall of metal that looks solid is actually 90% dense, allowing gas to pass through. Mold venting is one application.

Video: Support Structures Are Misnamed! How to Understand Anchors in Additive Manufacturing

By: Peter Zelinski

Supports or anchors can account for a significant share of both the engineering investment and material use in metal additive manufacturing. Michael Hansen of SLM Solutions discusses the role and importance of support structures.

Video: Metal AM Affects Plastics Production via Conformal Cooling

By: Peter Zelinski

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

By: Peter Zelinski

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

By: Peter Zelinski

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

By: Peter Zelinski

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.

Robot Is Production Solution for Laser Metal Deposition

By: Peter Zelinski

The move from prototyping to production might involve a move from machine tool to robot, but development work between Formalloy and the robot suppliers means the process and programming do not have to change.

The Promise of Robotic Metal Additive Manufacturing

By: Peter Zelinski

Addere’s robot-based laser system builds using standard weld wire. The company was spawned from a robot integrator, and that background has been valuable for both overcoming the challenges and perceiving the possibilities of using a robot for metal 3D printing.
