“…Because these filament materials are thermoplastic polymers, they may be heated to melt and soften and then chilled to restore their qualities. Furthermore, depending on whether they will be used as a commodity, engineering prototype, or high-performance item, materials used in FDM extrusion may be semi-crystalline or amorphous [ 31 ]. Three factors must be considered when using the FDM method to create bone scaffolds: design architecture, materials, and process parameters.…”

“…Build orientation refers to the position (direction and inclination) of the specimen in the build platform. Considering the X-, Y-, and Z-axes, the three main build orientations are flatwise, edgewise, and upright [ 86 , 88 ] ( Figure 12 ). Some authors highlighted the importance of build orientation on features such as build time, manufacturing cost, surface quality, geometric accuracy, and structural and mechanical properties.…”

3D Printing of Polymeric Bioresorbable Stents: A Strategy to Improve Both Cellular Compatibility and Mechanical Properties

One of the leading causes of death is cardiovascular disease, and the most common cardiovascular disease is coronary artery disease. Percutaneous coronary intervention and vascular stents have emerged as a solution to treat coronary artery disease. Nowadays, several types of vascular stents share the same purpose: to reduce the percentage of restenosis, thrombosis, and neointimal hyperplasia and supply mechanical support to the blood vessels. Despite the numerous efforts to create an ideal stent, there is no coronary stent that simultaneously presents the appropriate cellular compatibility and mechanical properties to avoid stent collapse and failure. One of the emerging approaches to solve these problems is improving the mechanical performance of polymeric bioresorbable stents produced through additive manufacturing. Although there have been numerous studies in this field, normalized control parameters for 3D-printed polymeric vascular stents fabrication are absent. The present paper aims to present an overview of the current types of stents and the main polymeric materials used to fabricate the bioresorbable vascular stents. Furthermore, a detailed description of the printing parameters’ influence on the mechanical performance and degradation profile of polymeric bioresorbable stents is presented.

“…To exploit the FFF technology for the fabrication of functional parts, the mechanical characterisation of the fabricated products is needed. In this context, various works have been presented in the literature with the aim of analysing different materials [ 14 ], process parameters [ 15 , 16 ] and growth directions [ 17 ], highlighting how all these variables affect the mechanical properties of the final product. It has been extensively demonstrated that the growth direction is associated with a lower ultimate tensile strength (UTS) [ 17 ], mainly due to a reduced interlayer bonding [ 8 , 18 , 19 , 20 , 21 , 22 ].…”

Filament Transport Control for Enhancing Mechanical Properties of Parts Realised by Fused Filament Fabrication

The fused filament fabrication (FFF) process is widely used for producing prototypes and functional parts for diverse applications. While FFF is particularly attractive due to its cost-effectiveness, on the other hand, the fabricated parts have limitations in terms of large manufacturing time and reduced mechanical properties. The latter is strongly influenced by the fabrication process parameters, which affect the interlayer bonding and the adhesion between consecutive layers. Several works presented in the literature analysed the correlation between mechanical properties and process parameters. It was demonstrated that an increase in the fabrication feed rate causes slippage between filament and the feeding system, which leads to a decrease in the extruded material flow, and thus in part density. This work aims to investigate how the limitation of the slippage phenomenon affects the mechanical properties of parts fabricated using the FFF process. A prototype machine, equipped with a closed-loop control system on filament transport, was used to fabricate samples for tensile tests and dynamical mechanical analysis. Samples fabricated enabling the filament transport control showed an increase both in ultimate tensile strength and elongation at break for those fabricated with disabled control, whilst a decrease in stiffness was observed. In addition, the results showed that the use of a filament transport control system on a FFF machine increases the possibility of fabricating high value-added parts.
