Prima Additive and Materialise are intensifying their collaboration in the optimisation of metal additive manufacturing systems. The collaboration between the two companies has led to the optimisation of the Print Genius 150, the additive manufacturing system by Prima Additive with Powder Bed Fusion technology featuring two lasers working on the same area. On this machine, Prima Additive has integrated Materialise's MCP (Materialise Control Platform) hardware control to obtain real-time control functions and a streamlined combination with external systems to assist the process, such as monitoring and control systems.
A major result of the integration between the Prima Additive and Materialise systems is the development of a laser Workload Balancing algorithm that allows to exploit the two lasers to the maximum and in a balanced way, optimising their workload. Thanks to this algorithm the two lasers are able to work in each layer for the same amount of time, automatically distributing the work in a homogeneous way and eliminating the moments in which only one of the two lasers is at work, maximizing the benefit of having two lasers on the same machine. The first Print Genius 150 resulting from this collaboration was installed at the University of Leuven, Belgium in April 2021.
Prima Additive 150 Family is a very flexible and smart machine platform. It is the best way to explore additive manufacturing, but also to develop new alloys and to qualify new materials and applications. All the machines of the 150 Family are equipped with different sensors that monitor the process in real-time, a double preheating system to heat the surface of the powder bed both from the top and from the bottom through the heated plate (up to 300° C), as well as the possibility to integrate lasers with different wavelengths (e.g. green lasers). Furthermore, the machine offers the user the possibility to set the laser parameters and the layer thickness in real-time during the job. Given the product’s characteristics, Materialise MCP adapts well to the software architecture of this family of machines and is a flexible tool of indisputable value to optimize the unique features of this machine.
The Materialise Control Platform is a machine-embedded hardware- and software-driven platform for advanced control of laser-based 3D printing processes. This solution is ideal for machine manufacturers, researchers, and 3D printing users who need to adapt the production process to meet specific needs. The MCP provides all the tools required for an easy-to-use, open and configurable system to connect, control and monitor all process-related hardware (Laser, Scanhead and Dynamic Focus). Consistent with Industry 4.0, the MCP is equipped with OPC ua and REST API communication protocols. It allows to get access to real-time data for analysis and empowers the user to profit from the real-time, closed-loop control function embedded in the MCP to further optimize the printing process and reduce costs by improving process repeatability while optimising printing efficiency.
