Polylactic acid (PLA) is produced from renewable materials, has a low melting temperature
and has a low carbon footprint. These advantages have led to the extensive use of polylactic …

Abstract Three-dimensional (3D) printing is a transformative fabrication process that allows
3D objects to be formed by the layer deposition of the materials. At present, a fused …

Additive manufacturing technology, and especially the material extrusion (MEX) process, is
far from the maturity level and, due to the contradictory data reported in literature, it requires …

Fused deposition modelling (FDM) is the extensively used additive manufacturing
technology because of its ability to make specimens having a complicated geometrical …

Among the FDM process variables, one of the less addressed in previous research is the
filament color. Moreover, if not explicitly targeted, the filament color is usually not even …

Purpose The rapid growth of 3D printing has transformed the cost-effective production of
prototypes and functional items, primarily using extrusion technology with thermoplastics …

Scientists around the world, as well as large companies, are trying to find the best solutions
to obtain both more environmentally friendly and sustainable product that responds as …

The use of biodegradable thermoplastic materials with applicability in various industries
such as automotive, consumer products, medical equipment and others has increased …

In this study, we implemented the simulation software Comsol Multiphysics to search for a
proper proportion of carbon-filled thermoplastic polyurethane (CTPU) and neat …

Fused deposition modeling (FDM) is becoming the most promised additive manufacturing
(AM) process in recent years due to the evident benefits, such as high design flexibility, low …
