Evaluation of Surface Quality in SLS‐Printed Nylon 12 Parts for Hygienic Applications in the Food Industry

Journal of Applied Polymer Science, Volume 143, Issue 17, May 5, 2026.
SLS‐printed PA12 specimens (untreated or VaporFuse Surface–treated) were evaluated by PAA sanitization (400 ppm; L. monocytogenes, E. coli, S. aureus) and ISO 3452–based penetrant testing, showing > 99.999% bacterial reduction on both surfaces and improved surface continuity after VFS.

Intelligent Operator‐Independent Flexibility in Robotic Non‐Destructive Evaluation

Advanced Intelligent Systems, Volume 8, Issue 5, May 2026.
Non‐destructive evaluation of high‐value components remains a manufacturing bottleneck due to rigid robotic calibration and fixturing. This study presents a flexible, adaptable system integrating 3D vision and force‐position control with a collaborative KUKA LBR robot. The geometry‐agnostic system enables pose‐independent ultrasonic inspection, detects

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

Engineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of
