I spent much of this week at the ASTM F42 committee on additive manufacturing. F42 is responsible for establishing a variety of standards for AM; the primary focus now is split between Materials & Processes on one hand and Design (which I participated in) on the other. I really enjoyed being there, and appreciate (see the link in "Evaluation") the rationale behind ASTM. But I also can't help wondering whether open source projects are better suited for some (not all!) of the problems that standards organizations are working on.

Somewhat coincidentally, I launched the first version of an open source project this week: Gongkai AM, a repository of user generated data on industrial 3D printing. Our first work: A complete overview of electron beam melting and Arcam machines. If you or anyone you know is working on industrial AM and wants to contribute, get in touch - or just submit a pull request!!


  • Via Brendan, a post on Fred Wilson's blog about having a calling card. I gotta say: documenting my own thoughts & output has (obviously, I suppose) become incredibly important to both my personal and professional life. Also, it's fun.
  • 3DSIM (maker of metal 3D printing simulation & support structure optimization software) is working with Sigma Labs (maker of in-process monitoring & analysis software). This makes a lot of sense.
  • A somewhat useful page on NAVAIR's (terribly designed) website about Technical Data Packages, which are key to their procurement process.



  • For NYIO, I'm looking for someone at the NYC DOT who would be interested in being on a panel discussion about urban logistics and the balance between modes of transit and public/private infrastructure. If you know of someone who fits that description, I'd love an intro!
  • From Jordan, how not to drop a giant ass anchor.


Stuff that doesn't fit into my dumb/arbitrary categories.

  • Tom Vanderbilt on the slush puddles in NYC's crosswalks, and on why sidewalks aren't (weirdly) within the purview of the city.
  • Via my father in law, John, I'm now reading "The Greatest Knight," a book about an actual knight who apparently became the archetype for chivalry and medieval power. John's recommendation: "It's the best management book I've ever read."


After a brief stint with the purpose-built Clearview,
the US Federal Highway Administration is moving back
to (the apparently inferior) Highway Gothic.
