3D Printed Sand Cores and Molds

Research Links Humtown: 3D Printed Sand Cores & Molds  ExOne S-Max Industrial Production 3D Printer – The S-Max system, designed for sand casting foundries, prints complex and accurate sand cores and molds directly from CAD data, eliminating the need for a physical pattern. Furan binder system requires no curing and guarantees cores and molds are ready for immediate casting. The ability to cast in hours without hard tooling improves the entire casting process chain. Furan Resin This binding system will not hold together inside of an oven at 2000 degrees Fahrenheit.

FirmWare Modification – Firmware ModKit

From DD-WRT website Most of the time you don't really need to re-build DD-WRT to make your desired changes. Now, this process has been made easy with the Firmware Modification Kit. This kit gives the user the ability to make changes to a firmware image without recompiling the firmware sources. It works by extracting the firmware into its component parts, then extracting the squashfs-lzma based file system (other file systems can be supported with tweaks). The user can then make modifications to the extracted file system, then rebuild the firmware image.
