Force distribution & 3D printed joints
The biggest challenge with 3D printed joints is the fact that they can not withstand large pull forces. In contrast they can cope with high pressure forces for a longer period of time. A more complex construction arose during the design process, resulting in a structure of push-only forces. To configure the best joints, we did an infinity analysis of the whole structure and every single joint, tube and surface within the product. Optimising the forces within the joints gave us the possibility to make the design as durable as possible. Further more we explored several 3D printing strategies, making them as easy and as fast as possible to print at home.

The HYA System
The HYA bench is a combination of 3D printed joints and readily available material that can hold up to 5 adults consisting of pressure forces only and with slim to no deflection within the materials. The bench is a manifestation of the HYA joint-system which lets you design your own furniture. Next to the 3D printed parts, we also designed a calculation function that lets you put in the dimensions of your base surface, configuring all joints and length of tubes automatically resulting in a bill of materials. Because the system is open source it is easy for everyone to create their own furniture with local (recycled) materials.
The HYA joints are optimised for internal forces and are therefore durable and long-lasting.
The joints have a minimised printing-time, making it accessible to produce at home with a consumer 3D-printer.
The HYA Bench construction can easily hold up to five adults. Making it a reliable construction for sofas and tables.
All materials used in the design of the HYA Bench can be bought at small construction markets, the printing material is ultimately made from recycled plastics.
