“…This aspect is crucial in terms of reusability, and precise, critical evaluations are still needed in terms of the sterilization of these medical instruments [ 22 , 31 ]. Furthermore, cost-effectivity analysis should be considered; however, the availability of 3D printing technologies is continuously increasing [ 32 ]. The limitations of our study also include the relatively low number of testing volunteers.…”

3D printing is an emerging and disruptive technology, supporting the field of medicine over the past decades. In the recent years, the use of additive manufacturing (AM) has had a strong impact on everyday dental applications. Despite remarkable previous results from interdisciplinary research teams, there is no evidence or recommendation about the proper fabrication of handheld medical devices using desktop 3D printers. The aim of this study was to critically examine and compare the mechanical behavior of materials printed with FFF (fused filament fabrication) and CFR (continuous fiber reinforcement) additive manufacturing technologies, and to create and evaluate a massive and practically usable right upper molar forceps. Flexural and torsion fatigue tests, as well as Shore D measurements, were performed. The tensile strength was also measured in the case of the composite material. The flexural tests revealed the measured force values to have a linear correlation with the bending between the 10 mm (17.06 N at 5000th cycle) and 30 mm (37.99 N at 5000th cycle) deflection range. The findings were supported by scanning electron microscopy (SEM) images. Based on the results of the mechanical and structural tests, a dental forceps was designed, 3D printed using CFR technology, and validated by five dentists using a Likert scale. In addition, the vertical force of extraction was measured using a unique molar tooth model, where the reference test was carried out using a standard metal right upper molar forceps. Surprisingly, the tests revealed there to be no significant differences between the standard (84.80 N ± 16.96 N) and 3D-printed devices (70.30 N ± 4.41 N) in terms of extraction force in the tested range. The results also highlighted that desktop CFR technology is potentially suitable for the production of handheld medical devices that have to withstand high forces and perform load-bearing functions.

“…As a result, it is important to present the projections of the AM that have a positive trend, for example, it will grow approximately by 15% between 2020 and 2025. The participation of the AM in the automotive industry will be 36% more for 2020-2025, 51% in participation for the aerospace and medical industry, and 23% for the printing of different types of devices [35,11,2,3,22]. Growth projections by region in trillions of dollars are presented graphically in Fig.…”

“…Regarding the development of AM considering the regions where it has had the most development [31], can be said that North America have been focused on manufacturing products for advanced aerospace technologies, as well as for the defense sector, in addition to manufacturing metal components and 3D printing for the automotive industry [2,32]. On the other hand, the direct competition of USA is China, because it has been focused on the development and mass 3D printing for the manufacture of aerospace components [33,34].…”

“…The development of manufacturing industry along with the development of new technologies, represents an area of interest concerning the impact that new technologies and the insertion of the Industry 4.0 has in a productive sector. Considering that situation, this research is focused on presenting the advances that the Additive Manufacturing (MA) has had, especially, the Fused Filament Manufacturing (FFF) technology, also known as Fused Deposition Modeling (FDM) due that this technology is the most used in the world [1][2][3][4]. This technology has a high acceptance due to low cost in equipment, materials diversity, easy processing, and exibility in operations [5][6][7][8].…”

This paper discusses Fused Filament Fabrication (FFF) technology to know their evolution and trends, analyzing the materials, workforce, machinery, methods, and management been used. A literature review is done regarding FFF usage between 2010–2020. Data is analyzed for identify the countries that are applying this technology, the industrial sector, academic resources available and a curve is fitted to data for forecasting a trend until 2025. Projections indicate a growth of 300% for workforce in FFF usage for 2025, 280% for machinery, 312% for materials, 275% for the creation and modification of methods and, 320% growth for management activities.

Additive manufacturing has allowed for businesses across the world to take advantage of reduced time taken to manufacture products, keep up with decreased lead times, and the challenges posed by online commerce. Automation has taken place in every aspect of the retail product development industry, and the rise of 3D printing has led to exponential industry and economic growth. However, research has shown that it is only the large manufacturers and corporations which have been able to take full advantage of additive manufacturing technologies, while small and medium sized enterprises are being left behind and face several challenges investing in such technologies and implementing them depending on their position in the supply chain. This paper will examine the economics behind 3D printing and additive manufacturing technologies, and emphasise the need for support to SMEs to achieve competitive advantages in using the technologies. Drawing from successful examples globally, the paper will pose policy recommendations for improved support to SMEs and guiding them through all the various stages required in implementing these technologies. The paper will also pose recommendations on reskilling and the requirement to train the existing workforce to meet the challenges of automation.
