Original Abstract

The submitted object is a one of a series of connecting pieces, enabling the construction of a wooden beam structure, such as a patio or a pavilion. The beams are 10 cm in diameter. The intent of the design is to showcase material properties and the possibilities of using it in the construction industry. The object is manufactured from polymer concrete, made up of recycled, post-consumer plastic, and aggregate (sand). The material has a working name - POLYBET. The main benefit of the material is its decent mechanical strength in tension compared to traditional concrete combined with a low price point due to the utilisation of waste that would typically be burnt or landfilled. The printer consists of a Kuka robot arm and screw extruder developed by our department in partnership with ViaAlta company. The prints are performed utilising 5-axis nonplanar strategies planned in Grasshopper, which allow us to print large overhangs and achieve improved surface quality.
