“…The resins containing 10% TMPTMA demonstrated higher flexural strengths than those containing high amounts of the oligomer ( Figure 4 ). The resin printed via 3D printing exhibited a flexural strength of 60–80 MPa, which was comparable to those of the PMMA and acrylic-based resins [ 39 ]. In other words, the as-prepared resin is suitable for medical and dental applications (temporary restorations, denture bases, etc.).…”

The main advantages of the three-dimensional (3D) printing process are flexible design, rapid prototyping, multi-component structures, and minimal waste. For stereolithography (SLA) 3D printing, common photocurable polymers, such as bisphenol-A glycidyl methacrylate (Bis-EMA), trimethylolpropane triacrylate (TMPTMA), as well as urethane oligomers, have been widely used. For a successful 3D printing process, these photocurable polymers must satisfy several requirements, including transparency, a low viscosity, good mechanical strength, and low shrinkage post-ultraviolet curing process. Herein, we investigated SLA-type photocurable resins prepared using Bis-EMA, TMPTMA, and urethane oligomers. The flexural strength, hardness, conversion rate, output resolution, water absorption, and solubility of the printed materials were investigated. The degree of conversion of the printed specimens measured by infrared spectroscopy ranged from 30 to 60%. We also observed that 64–80 MPa of the flexural strength, 40–60 HV of the surface hardness, 15.6–29.1 MPa of the compression strength, and 3.3–14.5 MPa of the tensile strength. The output resolution was tested using three different structures comprising a series of columns (5–50 mm), circles (0.6–6 mm), and lines (0.2–5 mm). In addition, we used five different pigments to create colored resins and successfully printed complex models of the Eiffel Tower. The research on resins, according to the characteristics of these materials, will help in the design of new materials. These results suggests that acrylate-based resins have the potential for 3D printing.

“…Before and after surface pretreatment, tensile vibrations of the CH 3 and C H groups in the benzene ring could be found at 1220, 1185, and 1161 cm À1 . Also, there was a peak at 1775 cm À1 for the tensile vibrations of the C O group, and the tensile vibrations of the aliphatic hydrocarbon C H and OH groups were observed at 2800-3040 cm À1 and 3040-3800 cm À1 , respectively 31,32 (Figure 13). Since the chosen method of surface pretreatment was a wet chemical method, the aliphatic hydrocarbon bonds and carbonate group bonds (in the branched chains) became the subjects for oxidative hydrolysis.…”

In the present study, the low pollution acidic potassium permanganate system has been used in the study of its micro‐etching effect on polycarbonate‐acrylonitrile butadiene styrene (PC‐ABS). Prior to micro‐etching using a N methyl pyrrolidone (NMP)‐glycol butyl ether solution was used as the swelling system of PC‐ABS. Reasonable swelling conditions were determined, a 2‐min expansion period at a temperature of 35°C with an NMP concentration of 80%. After the swelling processes, the effects of the volume ratio of :, micro‐etching temperature, and micro‐etching duration on the PC‐ABS surface morphology, surface roughness, surface hydrophilicity, and peel strength, have been investigated. It was finally determined that the best micro‐etching effect could be obtained by reacting at : = 1:2 and a temperature of 60°C for 25 min. The surface of the PC‐ABS copolymers was characterized by x‐ray photoelectron spectroscopy, atomic force microscopy, and Fourier‐transform infrared spectroscopy. The results showed that the micro‐etching process changed the morphology of the PC‐ABS surface and generated cavities. In addition, the surface roughness increased from the initial Ra = 9.69 to Ra = 197 nm. Also, the water contact angle on the PC‐ABS surface decreased from 92.2° to 28.6°, and the peel strength increased to 0.98 kN/m.

“…† The spectra for the ABS copolymers synthesized in emulsions and emulsion gels at different temperatures are very similar to each other, and also in line with those in literature. [61][62][63][64] The chemical compositions of the as-synthesized ABS copolymers were determined from the NMR spectra. 63 The as-synthesized ABS copolymers consist of acrylonitrile/butadiene/styrene segments 38/6/56 by mass, which is close to the original compositions for the monomers in the emulsion or emulsion gel systems.…”
