: Elemental Mapping of Multi-Metal 3D-Printed Structures

We were thrilled to collaborate with Ohio State's Materials as Extremes (MATX), led by Calvin M. Stewart, PhD, to push the boundaries of multi-metal 3D printing analysis. Supporting research by Britton DeGarmo, the Exum team utilized our Massbox to map the elemental composition of a multi-metal tensile bar, 3D-printed with stainless steel 316L and Inconel 718.

📊 Key Results:

◼️Elemental maps revealed high concentrations of Inconel’s key elements (Ni and Nb) on the left side of the sample, and steel elements (Fe and Cr) dominating the right.

◼️A high-resolution map with 25-micron resolution provided detailed insights into the transition zone where stainless steel and Inconel merged, critical for investigating migration of key elements.

◼️The transition zone's curved structure is typical of welded materials, and the curve's diameter matched expectations based on the printer's laser diameter.

This collaboration highlights the power of high-resolution elemental mapping in advancing additive manufacturing, allowing researchers to pinpoint key elemental variations that could affect performance under extreme conditions.

💡 Massbox makes it possible to visualize what’s hidden, creating new opportunities for innovation in materials science.

📸 We’re thrilled to share highlights from Christopher Pannier’s visit to Denver!

As a winner of the LIFT Materials Characterization Contest, Christopher and his team from the University of Michigan-Dearborn explored how our Massbox (LALI-TOF-MS) delivers precise, high-resolution elemental mapping to identify and diagnose defects in 3D-printed materials. 🏆

🔬 During this collaboration, the Massbox revealed critical elemental variations and defect insights across a 3D-printed iron disc, helping advance materials development and quality control in additive manufacturing.

âś… Key outcomes included:

Elemental Mapping: High-resolution maps of elemental variations with a 100-micron spot size

Defect Analysis: Detailed views of defect regions with elements like Al, Fe, Ca, and Ti

Depth Profiling: Layer-by-layer variation tracking to better understand structural integrity

A huge thank-you to Christopher Pannier and the University of Michigan-Dearborn team for their outstanding collaboration, and to LIFT for organizing this exciting contest that connects researchers with new characterization tools. 🙌
