AddMe Lab is the Additive Manufacturing laboratory established in 2014 at the Department of Mechanical Engineering of Politecnico di Milano. 

Within AddMe lab, research is conducted in different areas to meet the needs of the market from innovative product design to material characterization, new material development, process optimization, sensing, monitoring and zero-defect I4.0 solutions, post-processing, qualification and testing. The lab is mainly focused on metal additive manufacturing, but available processes and research activities cover also polymers, ceramics and composites. A new research stream on bioprinting has been recently added as well, in collaboration with the Department of Chemistry, Materials and Chemical Engineering “Giulio Natta”.

Currently, the AddMe.Lab is equipped with several Laser Powder Bed Fusion (LPBF) systems. The Renishaw AM250 and Trumpf TruPrint 3000 systems represent state-of-the-art industrial solutions that incorporate fiber lasers operating with pulsed and continuous emission modes, respectively. The lab includes also an "open" and highly sensorized LPBF system from 3D New Technologies with the ability to obtain high powder bed pre-heating. In addition to industrial systems, novel prototype systems have been developed and patented. The novel LPBF platforms encompass multi-material sample production, high temperature preheating capabilities as well as advanced defect monitoring and removal systems.

Within AddMe Lab, electron beam melting (EBM) is studied with an Arcam A2 system. The system was acquired as part of a collaboration between the Department of Mechanical Engineering, the Department of Aerospace Science and Technology and the Department of Chemistry, Materials and Chemical Engineering “Giulio Natta”.

The BLM ADDITUBE system is the laser metal deposition (LMD) system of the AddMe Lab designed and realized in collaboration with the BLM Group. The system consists of a coaxial powder deposition head positioned by an anthropomorphic robot while the workpiece is handled by a rotating and tilting table. It is equipped with sensors for in-situ monitoring and a powder feeding system for multi-material and multi-graded production.

The lab is also equipped with the ExOne Innovent System, one of the first units available in Italy based on binder jetting technology, the Efesto system, an innovative extrusion based deposition machine for the 3D printing and hybrid manufacturing of metallic and ceramic materials, which was patented in 2016 and a Desktop Metal Studio System+, one of the first installed in Europe, suitable for low-cost 3D printing of commonly used metals as well as copper.

The AddMe.Lab machine park is completed by a system of collaborating robots for the construction of large free-form structures through an extrusion/pultrusion system for the production of objects in continous fiber composite reinforced thermoplastic and thermosetting polymers, together with different systems for polymer 3D printing.

In order to have a complete grasp on additive manufacturing, the AddMe Lab is also equipped with innovative powder characterization and material testing facilities.
