“…Comparing studies related to the design of support for SLA printing [17][18][19] with materials other than those studied by this research, the studies concluded that support has little effect on tensile strength. However, there is a disadvantage: without support, materials will be saved, but accuracy will decrease compared to cases with support [20][21][22].…”

“…The SLA operation procedure is carried out as follows: In a photopolymer liquid tank, the print tray is submerged in a bath of liquid resin solution a fragile distance from the liquid surface (the tray is covered with a layer of liquid resin). The UV rays shine directly through the UV reflectors on the support tray, curing the liquid layer into a solid forming a precise cross-section of the part [2][3][4][5][6][7][8][9]. After each print layer is solidified, the print tray moves by one step, equal to the thickness of the print layer in the liquid, and the re-sweeping blade distributes the resin upwards in preparation for the formation of a new print layer.…”

Stereolithography (SLA) is a 3D printing technology commonly used in many fields. This advanced printing technology makes it possible to produce a wide range of products with smooth surfaces with high precision. Nowadays, 3D printing technology is the Top most effective with almost absolute accuracy. Support is still needed to print corner protrusions. Still, a more significant concern is to minimize the cross-sectional area at each print layer to avoid bias when removing a print layer from the silicone. Support structures in small columns or frame structures to keep the model in the correct position during printing are often created in preparation for stereolithography 3D printing. These structures are printed with the model and removed after printing. The support structure has an essential influence on the quality and accuracy of the 3D-printed product. In this study, the survey model is fabricated based on SLA 3D printing technology with different support structures, and the mechanical properties of acrylonitrile butadiene styrene like resin (ABS like resin) are tested. Check the parameters on the compression testing machine, and the results show that the two-headed support structure is optimal for the surveyed plastic materials.

“…Both SLA and DLP printing methods work by exposing a resin in liquid form to a light source, UV (ultraviolet) laser beam (for SLA) and stationary UV light (for DLP) [11,[12][13][14][15][16][17][18][19][20][21][22]25]. Evaluation of the tensile properties of a certain material is recommended, especially when in vitro studies of their clinical behaviour are limited [27][28][29][30]. According to Chantarapanich, additively printed materials have mechanical properties that can be affected by both the unprinted material properties and the manufacturing method.…”

“…Several studies investigated the effects of the aging process, building orientation of the layers and preconditioning [10,[21][22][23][24][25][26][27][28][29][30]. Furthermore the resin producer provided information about basic mechanical properties as well [20][21][22][23].…”

Introduction: The fundamental mechanical properties of 3D printed surgical guides used in orthodontics represent an important indicator for the accuracy of the insertion of skeletal anchorage devices. The tensile strength of devices printed by stereolithography (SLA) and digital light processing (DLP) methods, respectively, is influenced by factors such as finishing process. Aim of the study: This study illustrates a comparison of the tensile strength in two different types of 3D printed devices (SLA, DLP respectively) undergoing or not a standard process of polishing. Material and methods: Twenty-four specimens obtained according to ASTM D638-14 (Standard Test Method for Tensile Properties of Plastics) were used for the evaluation of tensile strength. Four groups of 6 samples from each category were created: SLA polished, SLA unpolished, DLP polished and DLP unpolished. After removing the support, finishing was performed to obtain smooth surfaces, according to the manufacturer’s recommendation. Type V specimen was used to perform tensile tests in accordance with the standard procedures ASTM D638-14 which recommends at least five specimens to be tested for each sample. One-way analysis of variance (ANOVA) and t-test showed statistically significant results at p < 0.05. SPSSv17 software was used for statistical analysis of the numerical variables, and also descriptive statistics were performed. Results: The measurements included: tensile strength (maximum load), tensile stress at maximum load and tensile strain at maximum load. The maximum load (tensile strength) of the polished specimens was lower, both for the SLA and DLP, with no statistical significance results. Conclusions: The conclusions indicated differences between maximum load and tensile stress at maximum load between polished and unpolished specimens, in both SLA and DLP groups. Althought the polishing process reduces the tensile strenght, the data analysis did not present statistically significant results.

“…The findings demonstrated that mechanical properties strongly depended on resolution, print direction, and UV curing time. Agrawal [15] attempted to determine which orientation angle is best for which kinds of loads, specifically the fracture test and the dynamic mechanical analysis (DMA) test. Various mechanical property values were obtained during the inspection process.…”

Three-dimensional printing has recently come into the spotlight due to its promising potential to create physically three-dimensional parts or structures through computer-aided design. While there are many options for 3D printing methods, photopolymerization 3D printing has garnered much attention because of its high resolution. However, the mechanical properties of photopolymerized 3D printed parts can vary widely depending on the manufacturing parameters and post-processing settings used. This research focuses on studying the effect of printing variables on the mechanical properties of samples printed using a Stereolithography machine (Formlabs, Form+3). Three variables are used: layer thickness (25 and 50 ?m), part orientation (X and Z directions), and post-curing. Also, eight groups of 3D-printed photopolymer specimens for twenty-four specimens are used for the tensile test results. The results showed the printing variables affected the mechanical properties of samples, which were proven by Young's modulus, ultimate stress, and ultimate strain. ABSTRAK: Pencetakan tiga dimensi baru-baru ini menjadi perhatian kerana potensinya yang menjanjikan bagi mencipta bahagian atau struktur tiga dimensi secara fizikal melalui reka bentuk bantuan komputer. Walaupun terdapat banyak pilihan bagi kaedah percetakan 3D, pencetakan 3D fotopolimerisasi telah mendapat banyak perhatian kerana resolusinya yang tinggi. Walau bagaimanapun, sifat mekanikal bahagian bercetak 3D fotopolimer adalah pelbagai bergantung pada parameter pembuatan dan tetapan pasca pemprosesan yang digunakan. Kajian ini memberi tumpuan kepada kesan pembolehubah cetakan terhadap sifat mekanikal sampel yang dicetak menggunakan mesin Stereolitografi (Formlabs, Form+3). Tiga pembolehubah digunakan: ketebalan lapisan (25 dan 50 ?m), orientasi bahagian (arah X dan Z), dan pasca pengawetan. Juga, lapan kumpulan spesimen fotopolimer cetakan 3D untuk dua puluh empat spesimen digunakan bagi mendapatkan keputusan ujian tegangan. Dapatan kajian menunjukkan pembolehubah cetakan mempengaruhi sifat mekanikal sampel, dibuktikan oleh modulus Young, tegangan utama, dan tarikan utama.
