MISILLA | a chair with 3D printed joints

Misilla is a small chair made of plywood and PLA 3D printed joints. The 3D printed joints are designed in order to fit exactly to the 15mm plywood and they could be used to solve similar problems in other applications.

Ergonomics determine misilla’s specific dimensions in order to make it comfortable for the user; while the key aesthetic objective is to combine these two opposite materials in a highlighting way for both of them.

Misilla’s frame is composed by two main pieces that shape the legs and the back and they are connected by four identical crosspieces that are fixed with a simple wood joinery system. Two identical pieces are designed to form the back and the sitting area of the chair and they are connected to the frame with the key elements of misilla’s concept, which are the 3D printed joints.
