Video: In Conventional Manufacturing, 3D Printing Is a Solution for Tooling

Tooling for conventional operations doesn't have to made conventionally. Rather than being made through machining, these welding fixtures are now made via 3D printing.

On a visit to a CNC machine shop, Precision Tool Technologies of Brainerd, Minnesota, I had a chance to note how 3D printing is being used as an aid to conventional manufacturing. The Stratasys Fortus 3D printer at Precision Tool is used to simplify the creation and modification of various tools used internally, including this welding fixture.

3D printing is a solution for tooling. [There are] lots of reasons for that: it's easy; the tool is done at the end of a print cycle; nothing more needs to be done necessarily.

This is a tool for a welding fixture used to make this, which is a device used in making eyeglass lenses. These springs are welded in using this fixture. In the past the fixture was machined. Also not that difficult, but here's the thing: the fixture, this part actually, is subject to change. That means the fixture has to change, and in the past, every time that happened it was a new machining project and more time at the machine tool.

3D printing makes tooling flexible, changeable, discardable. When the design of the product changes, just print a new tool.


  • The Hidden Complexities of Wire Arc Additive Manufacturing

    Lincoln Electric Additive Solutions’ robotic metal 3D printing process is a choreographed dance between welding, robots, automation, heat management and machining. The new venture may have a distinct advantage in the field: its parent company’s 125 year-old legacy.

  • CNC Machining as a Business Strategy for Additive Manufacturing

    As 3rd Dimension Industrial 3D Printing ramps up for production — including a fleet of new 3D printers in a custom-designed building — it's the company's traditional machining capabilities that provide a unique competitive advantage.
