Fuel3D is prepping to release its relatively inexpensive consumer 3D scanner next year after raising $6.4 million in a second Series A round. Investors contributed $2.6 million in the first round in February. On top of increasing production, Fuel3D will use the money to expand into commercial applications such as biometrics and eyewear. The startup recently started shipping its first units to Kickstarter backers, who were originally scheduled to receive them in April. 3D scanners are of particular interest to 3D printer owners, who can use them to scan physical objects and then print a replica.
