Early Stage Researcher (ESR) position for CT-based quality optimization of Selective Laser Sintering Description : You will focus on the use of CT to improve Additive Manufacturing (AM) processes. Your main focus will be on Selective Laser Sintering, which is the most important AM production process employed by Materialise. You will develop a quality control loop that uses the results of CT measurements (including detection porosity and defects in the material structure and dimensional accuracy) in order to improve the AM process. This comprises: 1) optimizing CT settings for different ...

Early Stage Researcher (ESR) position for investigation of probability of detection (PoD) of material defects Description : You will express the quality of CT measurements for material defect analysis in terms of probability of detection (POD). This POD depends highly on both the CT set-up (tube voltage and current, prefilter, …) and artefacts like beam hardening or scattering. Whereas the first constitutes rather global quality the latter is local due to local artefacts. You will start with the assessment of the POD for some typical defects in terms of local figures of merit, e.g. SNR, CNR ...

Early Stage Researcher (ESR) position for deveopment of an acceptance testing method for CT equipment Description : You will develop procedures for acceptance testing of CT metrology equipment. Due to the increased use of CT as coordinate metrology technology both users and manufacturers have a growing interest in standardization and regulation. You will therefore scrutinize the requirements on dimensional CT equipment, which are inherently different from NDT applications. For example, threshold settings and correct global scaling is of ultimate importance, while these points are often ...

Early Stage Researcher (ESR) position for the development of calibration objects and methods for ensuring traceable CT metrology Description : You will develop well-defined reference objects in view of traceability establishment. Progress is envisaged in terms of all relevant aspects, including design, manufacturing and calibration of reference objects. Procedures and reference objects will be developed in particular for testing of specific CT metrological characteristics that have not been fully studied yet, such as metrological structural resolution. Specific calibrated workpieces resembling ...

Early Stage Researcher (ESR) position for the development of advanced segmentation algorithms Description : In this project, you will approach improvements in the area of segmentation from two sides. First, you will identify and take into account the maximum information retrievable within a CT data set. Second, you will use information from additional sources. You will develop advanced segmentation algorithms, using a-priori information, multi-modal and multi-scale data, structural information and pattern recognition as well as a combination of those approaches. You will investigate if state ...

Early Stage Researcher (ESR) position for the development of a knowledge-based system for fast and accurate determination of CT scanning parameters Description : In this project, you will improve the set-up process of CT metrology by reducing the time necessary to find an optimized task-specific set of CT parameters (source settings, hardware filtration, orientation,…). This will be achieved by enhancing a knowledge-based system, which uses expert knowledge to support the decision to find the most suitable parameter set. The knowledge-based system follows a workpiece similarity approach ...

Early Stage Researcher (ESR) position for the development of dedicated calibration procedures for micro-parts Description : CT metrology procedures tailored to micro-parts are yet non-existent as are tailored calibration objects. Due to manufacturing and calibration measurement limitations, the simple scaling of the objects developed by ESR 5 will be insufficient, hence other geometries will need to be investigated. You will benefit from close cooperation with ESR 5 in order to speed up this development. In addition, you will make use of simulations in order to investigate the influence of ...

Early Stage Researcher (ESR) position for task-specifik uncertainty determination for CT metrology Description : You will develop a methodology that allows assessing the task-specific measurement uncertainty in Computed Tomography metrology in accordance to the ISO-GUM (Guide to the expression of uncertainty in measurement). Starting from a theoretical method for uncertainty determination, distinct uncertainty contributors for CT will be identified. Subsequently, a series of systematic measurements and simulations will be carried out to quantify the influence of the distinct contributors. A ...
