Here's a fantastic video by the great Dan Gelbart that reveals the secrets of producing high resolution metal and ceramic parts. This is fantastic! And it's something that every mad scientist needs to know about.
Please forgive the many obnoxiously long commercials that have been embedded. I turn down the wound and continue my work until they are finally over. (Does anyone know how to block these ads without having the pay for a monthly subscription?) Nevertheless, the content is will worth the wait. Enjoy!
