“…This finding is confirmed by the results of a study by Revilla Leon et al [ 49 ]. In general, there are several studies indicating an overall negative affect of aging on printable resins [ 14 , 18 , 37 , 39 , 53 , 54 ], and also one recent study that indicates that although there are negative effects on the mechanical properties, those are not significant [ 36 ]. Some other studies have proven the negative effect of aging on other 3D-printed objects, like complete denture bases and models [ 39 , 55 ].…”

The aim of this study is to investigate the influence of printing material, build angle, and artificial aging on the accuracy of SLA- and DLP-printed occlusal devices in comparison to each other and to subtractively manufactured devices. A total of 192 occlusal devices were manufactured by one SLA-printing and two DLP-printing methods in 5 different build angles as well as milling. The specimens were scanned and superimposed to their initial CAD data and each other to obtain trueness and precision data values. A second series of scans were performed after the specimens underwent an artificial aging simulation by thermocycling. Again, trueness and precision were investigated, and pre- and post-aging values were compared. A statistically significant influence was found for all main effects: manufacturing method, build angle, and thermocycling, confirmed by two-way ANOVA. Regarding trueness, overall tendency indicated that subtractively manufactured splints were more accurate than the 3D-printed, with mean deviation values around ±0.15 mm, followed by the DLP1 group, with ±0.25 mm at 0 degree build angle. Within the additive manufacturing methods, DLP splints had significantly higher trueness for all build angles compared to SLA, which had the highest mean deviation values, with ±0.32 mm being the truest to the original CAD file. Regarding precision, subtractive manufacturing showed better accuracy than additive manufacturing. The artificial aging demonstrated a significant influence on the dimensional accuracy of only SLA-printed splints.

“…While stereolithography has gained significant attention for its versatility and applications, the influence of aging on the mechanical properties of printed material has been relatively limitedly investigated. Aging processes (sunlight, X-ray), such as exposure to environmental factors, temperature fluctuations, or long-term usage, can potentially affect the structural integrity of the material and its overall performance [3,4]. In a previous study, signs of the effect of aging on mechanical properties have already been observed, but it was difficult to find information on this phenomenon because the manufacturer did not provide this type of information and the scientific community has only recently started to focus on this issue.…”

This paper focuses on stereolithography (an additive manufacturing technology working on the principle of curing liquid resins layer by layer using ultraviolet radiation) and the effect of aging on the mechanical properties of the material and printed samples. The aging of the material could be a problem for its subsequent use as the stability of the mechanical properties would not be maintained and unwanted deterioration of the material could occur. As part of the research, sets of samples were printed and subjected to different aging methods and subsequently subjected to quasi-static and dynamic uni-axial load tests. From the data obtained, the basic mechanical properties of the material were calculated and compared with each other. The aim of this paper was to investigate whether aging process causes significant changes in the mechanical properties of the materials used, which could have a consequential impact on their use in different industries.

The additive manufacturing route is a notably promising alternative option to obtain complex shaped parts, precise prototypes, and direct-usage system components for lots of independent sectors like medicine, dentistry, automotive, aviation, and construction. Compared to the conventional strategies, this methodology provides cleaner, healthier, and faster manufacturing opportunities for engineers and manufacturers. In this paper, actual applications of photopolymerization-oriented 3D printing in the field of dentistry are evaluated in light of the literature efforts, sectoral feedback, and additional original interpretations. Concordantly, the process backgrounds and printing materials were analyzed meticulously together with the evaluations of the physical and mechanical features of the dental components. When real implementations like models, surgical guides, aligners, temporary teeth, and implants are considered, it is seen that there is still a lot of room to be enlightened on this topic for a healthier future. In this context, this article aims to draw a broad perspective on the new interdisciplinary efforts and to emphasize the great potential of layer-by-layer production in the field of dentistry.
