Features of MaxQ
Our mission at RAMLAB is to accelerate the adoption of additive manufacturing technology to enable the wide-scale availability of certified metal parts on-demand. From our experience, we have learned that the most challenging aspect of WAAM is controlling the mechanical properties and the quality of manufactured parts. Many different factors affect the mechanical properties of a WAAM part, e.g. the design, the equipment and the wire feedstock to name a few. To achieve first time right manufacturing of certified parts, we have developed MaxQ: RAMLAB’s quality monitoring and control system for WAAM. The system monitors and controls the complete manufacturing process fully automated, freeing up time for the operator.
Geometry monitoring and correction
During production MaxQ automatically analyzes and adjusts the to-be produced geometry. Between every produced layer MaxQ’s 3D scanner inspects the surface. Whenever the welded layer diverges from the digital model, the following layer is adjusted accordingly. By adjusting the layers during production, MaxQ ensures a constant stick out of the wire resulting in constant material properties.
Precise anomaly detection and tracing
To achieve one time right manufacturing, defects need to be identified in near real time. MaxQ has a built-in anomaly detection system that can trigger alerts for the operator. Anomalies are detected by fusing data from multiple high fidelity sensors using algorithms to analyze the generated data. By matching the sensor data with the position of the robot, anomalies can be traced and resolved quickly.
Automated interpass temperature control
One of the most critical aspects of WAAM is the interpass cooling time: the interruption of welding in order to cool down the part and maintain the preferred material properties. MaxQ automatically measures the temperature and continues production when the part is cooled down to the set temperature. This means there is no more need for manual inspections between layers.

Guided process pipeline
MaxQ brings the WAAM production process together in one place. Production can be initiated straight from the web browser with the MaxQ app. Before starting production, MaxQ will guide the operator through automatic model parsing and the configuration of production settings. Simply upload, configure and start.
Clear machine diagnostics
Good preparation and maintenance of equipment are fundamental to manufacturing high quality parts. However, errors can still errors can occur during the manufacturing of a part. The MaxQ app notifies the operator of system warnings and errors. To ensure swift continuation, the corresponding error codes of the welding robot system are displayed on the dashboard. This way, the errors can be traced back and resolved with ease.
Advanced option: Grafana access
All the data recorded by MaxQ’s sensors is displayed on a private Grafana dashboard. Custom dashboards can be designed and warnings and alerts can be configured by the operator. The dashboard runs on a local server, which means there is no need for an internet connection. The data can be exported into a pdf report for class certification.
Advanced option: Cavitar C300
The Cavitar C300 welding camera is able to visualize the product surface, the weld pool and the arc in real time. This gives a detailed insight into the process stability, the weld pool, and other details such as neighboring weld beads, product edges, spatter and silicates. Learn more
