Cleaner 3D Prints Via Solvent Vapors and DLP Projectors

Jun 27, 2013   //   by Bob Warfield   //   3D Printing, Blog, DIY CNC  //  2 Comments

One of the issues with filament extruder based 3D printers is the quality of the surface they produce.  These printers are an amazing deal in terms of price, but sometimes the parts they produce can seem a bit crude with the filament layers being very visible.  There are at least a couple of ways to…

Video: CNC Router as Pick and Place Machine

Jun 10, 2013   //   by Bob Warfield   //   Blog, CNC Router, DIY CNC, Techniques  //  3 Comments

I wanted to call out Lindsay Wilson’s neat video of his CNC Router acting as a pick and place machine in its own post:

He mentioned it in a comment on our 2nd article on using CNC Machines as general purpose motion platforms.  Pick and place is commonly used to position components on circuit boards…

More on Using CNC’s as General-Purpose Motion Platforms
