Our end-effector

Heat source, material feed, and sensors printing metal reliably

Our first custom-designed hardware subelement

Throughout years of part building we have recognised the idea for monitoring and sensing during the deposition process. For reactive materials, there is also the need to provide inert atmosphere locally, should you wish to print larger parts than those which would fit within a tent or a chamber. Moreover, seen the criticality of wire position for off-axis feed processes, this must also be controlled during printing. This is why we have designed our own end-effector, at the core of our turnkey machines, connecting the point of deposition with our WAAMCtrl and WAAMDisplay software packages.

The end-effector is available for several processes and shielding configurations: with and without wire position motion system (non needed for coaxial-feed processes), as well as with and without local shielding option (not needed for non-reactive metals or in case or deposition within a tent or chamber)

The position of the end effector is recorded throughout the deposition process. The recorded trajectory is then matched with the data coming from all the other sensors.

Achieving the target layer height is just as important as is challenging, in directed-energy-deposition processes. Based on our unique laser interferometric solution, the layer height is continuously monitored and recorded, without any need to interrupt the process. This capability potentially enables the operator to perform corrective actions immediately, should the deviation be unacceptable.

A high-resolution camera looks at the side of the melt-pool and enables the operator to monitor the behaviour of the process remotely.

Arc current and arc voltage are monitored and their values recorded for quality control and assurance.

Wire feed speed is monitored and its value recorded for quality control and assurance.

Our proprietary closed-feedback-loops on wire position (for off-axis-feed processes) automatically adjusts the position of the wire, ensuring continued optimal metal transfer.

The temperatures before and after the deposition are continuously monitored and recorded by two pyrometers. These temperature values are used also to know when to start deposition, or to interrupt local gas shielding in the case of reactive materials like titanium.

The oxygen content within the deposition environment in continuously monitored and recorded.
