3D printed end mill

The latest episode of The Cool Parts Show looks at the intersection of additive manufacturing and machining. In the episode viewable below, co-host Stephanie Hendrixson and I look at a 3D printed end mill made by Guhring using a Markforged metal 3D printer. One of the questions we explore: Is additive manufacturing a competitor or complement to “subtractive” CNC machining? Answer: It is both. Additive manufacturing makes milling better in this case, because it produces a lighter-weight tool with more effective through-tool cooling channels. But additive also competes with machining, because machining is the way this type of tool body would otherwise be made.

Something else about the episode that makes it worth watching: The shop we visit to test this tool is none other than Dan’s Custom Machining, the subject of the cover story of Modern Machine Shop’s August issue. Watch this episode to see Dan and his shop in action.

The Cool Parts Show is the video series from Additive Manufacturing (the other publication I’m a part of) all about end-use parts made via 3D printing. This latest episode begins season 3 of the show. Subscribe to follow the rest of the season and watch the episode here:

  • Rolling Threads Has Advantages

    With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.

  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.

  • Tool Considerations for High Speed Cutting

    Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
