“…It is worth to mention that few infill strategies have been developed and tested on curved layers [128,132,135,230,231] in order to leverage the extended possibilities provided by RBAM. In particular, basic infill patterns have usually explored, i.e., raster and zig-zag infills, and few physical tests have been performed on functional parts.…”

Nowadays, robot-based additive manufacturing (RBAM) is emerging as a potential solution to increase manufacturing flexibility. Such technology allows to change the orientation of the material deposition unit during printing, making it possible to fabricate complex parts with optimized material distribution. In this context, the representation of parts geometries and their subsequent processing become aspects of primary importance. In particular, part orientation, multiaxial deposition, slicing, and infill strategies must be properly evaluated so as to obtain satisfactory outputs and avoid printing failures. Some advanced features can be found in commercial slicing software (e.g., adaptive slicing, advanced path strategies, and nonplanar slicing), although the procedure may result excessively constrained due to the limited number of available options. Several approaches and algorithms have been proposed for each phase and their combination must be determined accurately to achieve the best results. This paper reviews the state-of-the-art works addressing the primary methods for the representation of geometries and the subsequent geometry processing for RBAM. For each category, tools and software found in the literature and commercially available are discussed. Comparison tables are then reported to assist in the selection of the most appropriate approaches. The presented review can be helpful for designers, researchers and practitioners to identify possible future directions and open issues.

“…Hybrid printing machines allow the manufacture of unique parts, that are more complex than those produced on 3D printers, due to the fact that a hybrid machine has positioning accuracy, a working stroke and rigidity far superior to 3D printers. [26,27,28,29,30,31,32,33,34,35] In order to 3D print on 5-axis hybrid machine tools, in the first phase the 3D model of the part is created and converted into a 3D printed extension program using a post-processor capable of generating codes (NC-code).…”

This paper presents an original method of additive manufacturing of cylindrical parts with variable circumference thickness, which allows the control of the deposition of molten material using an algorithm for decomposing the part geometry into volumetric elements with known dimensional configuration. In the absence of a post-processor capable of controlling additive manufacturing on a 5-axis numerical control machine, control of the deposition of molten material is done using parameterized programs, which can control both the feed speeds of the machine tool axes and the specific functions of the printing equipment. Additive manufacturing can make a positive contribution to sustainable development compared to traditional manufacturing technologies, thus making a positive contribution for a sustainable future. The aim of the work is to make it possible to 3D print parts with variable wall thickness using a CNC machining centre. To obtain the variable thickness layer we have implemented an original method of deposition with molten material (FDM), the coordination of the system composed of physical elements respectively programmable elements, is realized through control functions materialized in parameterized part programs, the generated outputs being the variable speed of the machine axes on a circular trajectory, the angular positioning, the filament advance.

“…While great strides are being made, the relatively poor mechanical strength and weak interlayer adhesion between the successive layers of FFF-printed components can lead to inaccessible damage within the polymer matrix, which can lead to higher material failure rates. − Moreover, application of FFF 3D printing is limited by relatively poor surface roughness and accuracy of 3D printed parts. − There are numerous factors responsible for the ultimate mechanical properties, and thereby use cases and useful lifetimes, of 3D printed components, including layer thickness, orientation of filaments during 3D printing, air gaps between layers, and process of filament solidification during extrusion for which ongoing research has sought to optimize the mechanical properties of FFF-printed specimens. , For instance, the use of reinforcement fillers such as carbon nanofibers has enhanced the mechanical strength of FFF-printed components, although there are remaining challenges, including fiber orientation in the polymer matrix, fiber–matrix debonding, and void formation. , Another approach to improve the 3D printed component lifetimes and reliability is to use a material system which autonomously heals itself, that is, self-healing. − …”

Fused filament fabrication (FFF) is a widely used additive manufacturing process that is increasingly adopted for prototyping and is growing in popularity for manufacturing. Simultaneously, there is increasing consideration of material lifecycles in choosing and designing materials and material processing techniques. One approach to extending material lifetimes is enabling the recovery of material properties after damage through an autonomous self-healing behavior. Here, we investigate the microcapsule-solvent-based self-healing of high-impact polystyrene (HIPS), a common thermoplastic polymer, toward increasing FFF three-dimensional (3D) printed specimen lifetimes and improving material sustainability by fabricating robust materials. Double-walled self-healing microcapsules filled with an environmentally friendly ethyl phenylacetate solvent are synthesized using in situ interfacial emulsion polymerization and coated on polymer filaments prior to FFF 3D printing. The ability of these microcapsules to sustain the FFF 3D printing process is demonstrated, and the self-healing performance of FFF 3D printed HIPS composites is evaluated via quantification of mechanical properties and healing efficiency (up to 81% healing efficiency is achieved).
