In Laser Powder Bed Fusion (LPBF) additive manufacturing machines, a laser galvanometric scanning system is used to control the movement of the laser beam, which melts material powders layer-by-layer in a powder bed. Errors between desirable positions and actual positions of the laser in the work plane of the machine directly affect the geometry ac...
The soil, at the interface between geosphere, biosphere, and atmosphere, is a particularly challenging object to study. The ecological and environmental impacts of soil functioning encourage soil scientists to exploit new technologies to generate new data or develop new research protocols. Among these technologies, 3D printing is a promising techno...

The electrochemical response of laser powder bed additively manufactured Ti6Al4V is often considered at room-temperature conditions; however, structural Ti6Al4V components in a warm marine environment tend to respond differently. In light of this, the present work investigates the electrochemical response of the Ti6Al4V fabricated using laser powde...

This research presents results for the design and creation of supporting teaching materials using additive manufacturing. The materials are inspired by selected artwork of four animal species, which belong to a collection from the museum of the University of Antioquia. The topic selected was fauna in Colombia, and the animals in question were chose...
The use of large beams in the Laser Powder Bed Fusion (L-PBF) process has been receiving increasing attention for the past few years and may widen the dissemination of this technology in the industry, as well as help increase the production volume. In this paper, a detailed comparison is presented between a usual 80 μm diameter Gaussian laser spot ...

Additive manufactured Ti6Al4V reinforced with nano yttria-zirconia (nYSZ) parts were fabricated using selective laser melting technology (SLM). The as-received Ti6Al4V powder and two powder mixtures of Ti6Al4V mixed with several nYSZ contents (1wt% and 2.5wt%) were prepared and then SLM processed. Parts were further subjected to a stress relief hea...

Biofabrication of personalized titanium scaffold mimicking that of the osteocyte microenvironment is challenging due to its complex geometrical cues. The effect of scaffolds geometrical cues and implantation sites on osteogenesis is still not clear. In this study, personalized titanium scaffolds with homogeneous diamond-like structures mimicking th...
