# Key Points from #hplusroadmap IRC Log (May 11, 2011)

• A 3D printing design challenge for human augmentation was shared (http://i.materialise.com/challenge/i-materialise-machine-man-human-augmentation-design-challenge), with participants noting that 3D printing in titanium was possible using Direct Metal Laser Sintering (DMLS) technology.

• The Open Source Hardware, Electronics and Robotics Convention (http://oshwcon.org/en) was mentioned as a relevant event for the community.

• SENS Foundation's year-end report was referenced, highlighting their development of candidate enzymes that can attack components of lipofuscin, a significant development for anti-aging research.

• Seasteading (creating permanent dwellings at sea outside territorial waters) was discussed, with mentions of coverage by The Economist and Fora.TV, showing mainstream media interest in alternative governance models.

• Technical resources for STEP (Standard for the Exchange of Product model data) file format were shared, including implementation documentation at http://diyhpl.us/~bryan/irc/step/fundimpl.pdf for CAD interoperability.

• Discussion of approaches to STEP implementation revealed two methods: generating correctly formatted output (described as the "wrong way") versus writing a proper EXPRESS parser to read/write STEP files (the "correct way").
