# Summary of IRC Log from August 20, 2013

* A discussion took place about manufacturing complex metal structures at the micrometer scale, with archels seeking advice on 3D printing or other manufacturing techniques for microelectrodes with fractal geometry at approximately 5μm resolution.

* Several potential solutions were suggested for micromanufacturing, including focused ion beam (FIB) shops, MEMS fabrication at universities, and commercial services like Microtec (Germany) and Nanoscribe, which uses 2-photon UV polymerization.

* Technical papers were shared on 3D micro-additive manufacturing technologies, with specific references to LCVD (Laser Chemical Vapor Deposition) and FIB (Focused Ion Beam) techniques for creating microstructures.

* A GitHub project called "exterminate" was shared (https://github.com/substack/exterminate), though its specific purpose wasn't elaborated in the conversation.

* The paperbot tool was demonstrated throughout the conversation, allowing users to retrieve academic papers by providing URLs, with the bot returning direct links to PDF versions of the papers.
