# Key Points from #hplusroadmap IRC Discussion (Dec 7, 2009)

• Participants discussed bioprinting technology, specifically how hydrogels function as scaffolding for cells in organ printing, referencing Organovo's commercial 3D bioprinter announced in December 2009.

• DIY fabrication technologies were compared, including RepRap, Fab@Home (costing around $3,000), and professional Stratasys 3D printers, alongside links to DIY inkjet printer modifications for nucleotide printing and hydrocolloid recipes.

• The group analyzed the Lawrenceville Plasma Physics fusion project, sharing criticisms from a national laboratory about radiation cooling issues that could impact the project's viability.

• SKDB, a package management system for open hardware, was discussed in detail, with participants debating repository organization and the need for better documentation of the system architecture.

• Genomic sequencing technologies were examined, including AFM/STM sequencing methods and the rapidly decreasing costs of genome sequencing, with speculation about mass-production possibilities.

• The conversation referenced recent H+ Summit presentations by Todd Huffman, Bryan Kanzure, and Patri Friedman, with participants working to improve the poor-quality recordings hosted on Justin.tv.
