CGTrader, The fastest growing community and marketplace for 3D graphics and printing designs, today announced the 3D Printed Kids' Toys Challenge to test the popularity of the 3D printable toys and games theme among its designers. As 3D printing technology offers a rich but yet mostly-untested potential to bring interactive play experience for children and adults alike, CGTrader.com hopes the experiment will appeal to 3D designers on a lookout for interesting projects and emerging niche markets within the 3D printing industry.
