CES 2011: 3D printed sculptures, comfy Yurbuds and Casio's latest graphic calculator

3D printing experts Shapeways make it easy for creators to get rapidly-produced real-life physical designs shipped to their door. Dmitry Kobzar used it to recreate the cover of Cory's novel Makers, and the company had these beautiful examples on show at CES satellite event Showstoppers.

After finding that custom-molded earbuds still caused some wearers pain, Yurbuds spent more than $1m researching the optimal shape for earbud comfort. The results look weird but feel great, with two sizes in the retail box and others available for order.

Casio's Prism fx-CG10 graphing calculator, with a full-color display, USB transfer and a $130 tag, is designed to dethrone an industry standard. "Holding this up to a Texas Instruments model is like holding an iPod Touch up to a Walkman," said Casio's Mike Reiners.
