Analysis of a binder jetting 3D printer and temperature control of print-bed

This thesis is based on internship experience in Concr3de B.V. that is a start-up company based in Rotterdam (Netherland) that are developing a 3D printer by using binder jetting technology, a powerful method of additive manufacturing that enable to create object with complex geometry, with sustainable concrete as base material. The freedom to use different powder mixes allows creators to obtain stone parts with high precision, durability, sustainability and good physical and chemical properties. The goal of this thesis is to give an overview of binder jetting 3D printing technology used by Concr3de and a first approach on the PID temperature control of print-bed with PLC programming. Certain materials have a positive effects of increasing temperature during printing process obtaining an increasing of reaction rate between powder and binder that could lead improvement of final short and long term strength of printed object.
