Reply to "3D printing, the future?"

So is FDM printing.  It is the engineering that goes into the printers.  The low-cost resin printers use LCD panels like in your TV and phone to mask each layer.  Mono LCD panels are used now instead of color which results in faster printing and longer panel life.  An array of UV LEDs instead of scanning lasers set the resin.  That's why you can get a small printer for under $200.  The build area is limited by the size of the LCD panel.

Mechanical techniques like the traveling laser in the Formlabs printers make for a larger build area.
