Large-scale additive manufacturing (LSAM) is an process based on the principles of fused filament fabrication but with significantly higher material deposition rates. The novel hybrid shown in this paper combines LSAM a laser beam heat treatment. structure and mechanical properties parts are improved due to decreased void sizes. following article details investigations into vertical lateral rem...

The modern aircrafts are built using various composite materials such as carbon/glass fibre reinforced plastics, GLARE and honeycombs. Manufacturing technologies of composite materials are complicated and include many stages. Small deviations from the technology parameters may cause relatively small defects, but influence of these defects on a total strength of a construction may be essential. ...

Living organisms such as bacteria are able to grow, respond to stimuli, and divide as part of their life cycle. Designing smart three-dimensional (3D) materials that are able to perform such feats, i.e., continue on-demand growth and respond to external stimuli, is always a challenge for polymer and material scientists. At present, Johnson and co-workers have made a significant step forward in ...

The advantage of additive manufacturing (AM) (e.g. reasonable time and expense in prototyping, and reliable product) has triggered the idea of using this method in manufacturing of marine vessels components. The current article tries to introduce basic concepts of AM method and its application in marine industry; have a glance at additive-manufactured parts microstructure; elaborate the challen...

Additive Manufacturing (AM) technologies build near-net shape components one layer at a time using data from 3D CAD models. AM technologies are the result of evolution of work in 3D printing and stereolithography (the STL files used to convert 3D CAD to layers for building parts come from stereolithography terminology) and could revolutionize many sectors of U.S. manufacturing by reducing compo...
