3D Printed Metal Ratchet Wrench is Better than Your Dad’s

3D Printed metal parts are manufactured using Direct Metal Laser Sintering (DMLS). Stratasys Direct Manufacturing has been working to perfect their manufacturing methods for DMLS and officially released sintered metal products into their custom manufacturing solution line earlier this year. DMLS manufactured parts have proven especially beneficial for aerospace components using Inconel 625 and Inconel 718, materials that afford excellent heat and corrosion resistant properties.  DMLS provides high quality metals that challenge the geometric parameters of traditional manufacturing methods while obtaining fast production times.

A recent application of DMLS looks to transform one essential element of your toolbox: the wrench.

The patented New Ratchet 3rd Generation (NRG3 for short) is a roller wrench 3D Printed with DMLS. Stratasys Direct Manufacturing provided early 3D Printed prototypes utilizing Laser Sintering (LS). Stratasys Direct Manufacturing also produced functional metal components using DMLS, including the spindle cage and lever, for the production ready wrench. (To learn more about the wrench, visit Roller Clutch Tools).

DMLS, as an additive manufacturing (3D Printing) process, is able to consolidate parts. Features that would normally require additional assembly or machining are easily built directly into the part. Internal and external features are simultaneously grown from the ground up, resulting in less bulky and therefore lighter parts. Stratasys Direct Manufacturing also provides Cobalt Chrome and Stainless Steel 17-4 sintered metal components.
