The Cobb County Board of Commissioners voted 5-0 Tuesday to establish a fee for 3D printing beginning Monday.

The minimum cost will be $2.50 for a single print job at a Cobb library.

For each gram of filament, 15 cents will be charged.

Last year, Cobb received a state grant to buy five 3D printers for the county’s library system.
