Abstract

The built environment contributes in a large extend to the global greenhouse gas emissions. With a growing demand for new buildings another view on building products is required. This thesis focusses on creating a biobased sound absorbing panel made from a mycelium bound biomaterial derived from urban waste. The production method for this panel is 3D printing, since with this production method changing demands can be met.

In this thesis six experiments are executed regarding the development of a printable material from urban waste, the sound absorbing properties of the designed panel and 3D printing. To create a printable paste from urban waste, a couple of urban waste materials have been reviewed. Brewery’s grain came out as the most promising growth medium for mycelium. This material is mixed with flour and water to create a printable paste.

The impedance tube B&K 4206 is used to discover the acoustic properties. For the 3D printing a UR5 robot in combination with a LDM WASP extruder 3.0 XL is used. To control the robot movement, Rhino with Grasshopper in combination with the plug-in Robots is used. For understanding the acoustic behavior of the panels, multiple variables regarding printing and design parameters have been tested.

The final product of this research is a 3D printed panel which can be made with a mixture of brewery’s grain, all-purposes flour, water, and mycelium from the Pleurotus.
