3D printing has a large potential to produce large variety of complex shapes. It gives freedom of design in complexity of geometry. 3D printing has an advantage of no tooling design for desired shape. Sound absorbers are becoming an extraordinary solution to reduce impact of outdoor and indoor noise pollution. 3D printed sound absorbers are having a great demand in recent years. Typical production methods are limiting shape possibility and variety of absorber plates fabricated. So 3D printers are used in acoustical industries to fabricate absorbing plates in wide variety at low cost with precision. We have fabricated an absorptive plate with 60% porosity and porous holes in it. We have characterize absorption system using standard impedance tube method (ASTM C384-04) to study its absorption and transmission loss properties. They show very good absorptive properties for high frequency application and good transmission loss value.
