Assessment of the accuracy of 3D printed medical models through reverse engineering
Adugna, Yosef Wakjira; Kurukkal, Navaneethan S.; Lemu, Hirpa G. (Peer reviewed; Journal article, 2024-06)The dimensional accuracy of additively manufactured (3D printed) medical models can be affected by various parameters. Although different methods are used to evaluate the accuracy of additively manufactured models, this ... -
Comparative evaluation of stress concentration generated on human femur structure using meshfree software
Adugna, Yosef Wakjira; Lemu, Hirpa G. (Lecture Notes in Electrical Engineering;994, Chapter, 2023)Norway is one of the countries with the highest registered incidence of hip fractures in the world. About 60% of the hip fractures are in the femoral neck, few in the caput and the rest are in the trochanteric region, ... -
The influences of international standards on structural performance and fracture behavior of 3D printed long fiber composite structures
Akessa, Adugna Deressa; Adugna, Yosef Wakjira; Tucho, Wakshum Mekonnen (Peer reviewed; Journal article, 2023)The material properties of the additive manufactured composite structures are usually done following international standards, that show some difference dimensionally. This study focuses on the impact-induced on the tensile ... -

Adugna, Yosef Wakjira; Kurukkal, Navaneethan S.; Lemu, Hirpa G. (Peer reviewed; Journal article, 2024)Reverse engineering, a process of extracting information or knowledge from existing objects or systems, has gained significant attention in various fields, including medicine. This article presents a comprehensive literature ... -
Study of medical image data transformation techniques and compatibility analysis for 3D printing
Kurukkal, Navaneethan Sahasthiranatha (Master thesis, 2022)Various applications exist for additive manufacturing (AM) and reverse engineering (RE) within the medical sector. One of the significant challenges identified in the literature is the accuracy of 3D printed medical ... -
Triply periodic minimal surfaces based functionally graded biomimetic scaffold fabrication via stereolithography
Adugna, Yosef Wakjira; Lemu, Hirpa G.; Hagland, Hanne Røland (Peer reviewed; Journal article, 2023)Triply Periodic Minimal Surfaces (TPMS), a class of intricate mathematical surfaces, have emerged as a promising framework for scaffold design due to their ability to replicate the complex geometries found in biological ...
