“…It should be noted, however, that a slight gradual loss of sample mass was present already from the beginning of the heating of the sample. The same tendency could be observed with ABS samples, though, in that case, the gradual decrease in sample mass started at higher temperatures [ 24 ]. Interestingly the TGA curve of the tested clear resin ( Figure 4 ) is very similar to that of PLA shown in a previous study [ 24 ].…”

We report the additive manufacturing of a heat-exchange device that can be used as a cooling accessory in a wire myograph. Wire myography is used for measuring vasomotor responses in small resistance arteries; however, the commercially available devices are not capable of active cooling. Here, we critically evaluated a transparent resin material, in terms of mechanical, structural, and thermal behavior. Tensile strength tests (67.66 ± 1.31 MPa), Charpy impact strength test (20.70 ± 2.30 kJ/m2), and Shore D hardness measurements (83.0 ± 0.47) underlined the mechanical stability of the material, supported by digital microscopy, which revealed a glass-like structure. Differential scanning calorimetry with thermogravimetry analysis and thermal conductivity measurements showed heat stability until ~250 °C and effective heat insulation. The 3D-printed heat exchanger was tested in thermophysiology experiments measuring the vasomotor responses of rat tail arteries at different temperatures (13, 16, and 36 °C). The heat-exchange device was successfully used as an accessory of the wire myograph system to cool down the experimental chambers and steadily maintain the targeted temperatures. We observed temperature-dependent differences in the vasoconstriction induced by phenylephrine and KCl. In conclusion, the transparent resin material can be used in additive manufacturing of heat-exchange devices for biomedical research, such as wire myography. Our animal experiments underline the importance of temperature-dependent physiological mechanisms, which should be further studied to understand the background of the thermal changes and their consequences.

“…The most commonly applied materials for manufacturing the 3D objects are ABS and PLA, which may differ from metallic alloys with other thermoplastics [61]. PLA as the most widely used biodegradable polyester has the strong potential to be applied in industrial applications or in medicine as a biomaterial.…”

As radiotherapy techniques have been becoming more applied in medicine, the success of radiotherapy treatment lies in an optimal radiation dosage distribution in tumor as well as dose limitation to the normal tissues. Accordingly, the application of three-dimensional (3D) printing technology, as an additive manufacturing (AM) process in radiotherapy technique, is proliferating rapidly due to the reduced manufacturing costs, improved printing precision, and the speed of 3D printers. The advent of 3D printers in medical fields, especially in radiotherapy, allows to produce any given specific design for patients from novel 3D printable materials. Generally, the applications of this modern industry in radiotherapy can be counted as the creation of traditional patient-specific bolus, brachytherapy applicators, personalized medical devices, physical phantoms for quality assurance (QA), compensator blocks, and patient-specific immobilization devices. Despite the technological advancements of 3D printing in radiotherapy practices, due to the high manufacturing cost, the printing speed, time-consuming workflows, poor conformability, and poor repeatability of applied materials, it is not currently well supported by most radiotherapy techniques. The applications of the 3D printing technology as well as its limitations in radiotherapy are discussed in following.

“…This manufacturing technology is currently used in a large variety of medical and biomedical applications including anatomical or experimental models, medical devices, prostheses and implants, scaffolds, tissues and organs, anatomical structures, and drug delivery systems [11][12][13]. Vat photo-polymerization, droplet-based, extrusion-based, and powder-based 3D-printing techniques have already proven their importance for modern dentistry, covering a wide range of indications (Figure 1) [14].…”

3D-printing application in dentistry not only enables the manufacture of patient-specific devices and tissue constructs, but also allows mass customization, as well as digital workflow, with predictable lower cost and rapid turnaround times. 4D printing also shows a good impact in dentistry, as it can produce dynamic and adaptable materials, which have proven effective in the oral environment, under its continuously changing thermal and humidity conditions. It is expected to further boost the research into producing a whole tooth, capable to harmoniously integrate with the surrounding periodontium, which represents the ultimate goal of tissue engineering in dentistry. Because of their high versatility associated with the wide variety of available materials, additive manufacturing in dentistry predominantly targets the production of polymeric constructs. The aim of this narrative review is to catch a glimpse of the current state-of-the-art of additive manufacturing in dentistry, and the future perspectives of this modern technology, focusing on the specific polymeric materials.
