Bridging Computed Tomography and Additive Manufacturing—A path towards Quality and Innovation

Industrial Computed Tomography (iCT) and Additive Manufacturing (AM) share a fundamental connection—both revolutionize industrial processes through non-destructive analyses and flexibility. As AM pushes the limits of design complexity, iCT emerges as a decisive enabler for guaranteeing quality, structural integrity, and material inspection.

This series of presentations will explore several iCT methodologies for quality inspection and material characterization, including offline use, online and inline analyses, and real-time tracking of material microstructure evolution (4D iCT). Examples of applications from leading manufacturing companies will span car batteries, polymer/composite AM parts, and neutron and X-ray high-energy-iCT problem-solving.

Whether validating intricate lattice structures, optimizing composite materials, or overcoming the challenges of tomographic volumetric printing (TVP), this discussion will unfold how iCT and AM together can drive the reliability and efficiency of next-generation manufacturing solutions.

Forensic engineering: Fatigue cracks in glass fiber/polymer composite

Thomas Kjærgaard, Operation Quality Manager, Grundfos, Denmark

CT scanning is an important tool for simulation-driven optimization of fiber/polymer composites, providing high-resolution, non-destructive imaging to identify defects affecting performance.

A key application is root cause analysis of cracks and structural failures. By integrating CT analysis with robustness testing and material characterization, engineers can correlate defects like fiber misalignment, voids, or resin inconsistencies with mechanical performance, improving failure predictions and material designs.

CT scanning also validates simulations, ensuring manufacturing processes meet durability requirements. Its ability to detect microscopic defects makes it indispensable in many applications.

Ultrafast Volumetric 3D Printing via Reverse Tomography

Aminul Islam, Associate Professor, DTU Construct, Denmark

Tomographic volumetric 3D printing (TVP) is an emerging additive manufacturing (AM) method inspired by reversed computed tomography (CT). TVP enables the creation of a 3D energy distribution within photoresin by projecting 2D light images from multiple angles for a rapid and simultaneous solidification of the entire object in all directions. The process can produce parts at an unprecedented printing speed, generate extremely smooth surfaces, remove support structures and layer induced defect. It has even demonstrated, for the first time in the history of 3D printing, the ability to produce parts with variable stiffness and functional grading. However, the state-of-the-art TVP suffers from striation effects, inconsistency in surface generation, repeatability and precision issues which hinder the industrial adoption of technology.

Another fundamental limitation to this emerging technology is the non-negativity constraint, i.e., light engines cannot deliver the information carried by the negative values in a tomogram. This affects the printing quality and accuracy of the part produced by TVP.

This presentation will focus on recent research to overcome some of these limitations to achieve higher accuracy and less variation in the parts produced by TVP.

Prof. Aminul Islam is working as an Associate Professor in the Department of Civil and Mechanical Engineering at the Technical University of Denmark (DTU) and currently serving as the Head of Studies for DTU education in Bachelor of Science in Mechanical Engineering.
