About RF Cafe

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

3D Printers and Fabrication

MakerBot 3D Printer - RF cafeHeadlines are filled every day with new, radical applications for the rapidly advancing 3D printer phenomenon. 3D-printed prototypes for developmental models have been around for a few years now, but the paradigm is chancing to include finished products. Just as you can send a file for a printed circuit board that you design to a vendor for rapid turn-around fabrication, you can now ship a 3D CAD file to companies that will print your object. Capability has increased while prices have decreased on 3D printers over the past couple years. This page contains information on companies that provide products and/or services for 3D printing.
