“…From the technical point of view, both (linearly and nonlinearly induced photopolymerization) are already well studied: achievable spatial resolution, manufacturing throughput and printable objects sizes. The applications part is well examined too, and covers a wide range of realizations: from rapid prototypes manufacturing 44 and medicine 45 , to delicate sensors 46 , lab-on-chip 47 , metamaterials 48 and micro-optics 49 fabrication. Recently, a lot of attention has been focused to the materials used in O3DP for their functionality.…”

Materials obtained from renewable sources are emerging to replace the starting materials of petroleumderived plastics. They offer easy processing, fulfill technological, functional and durability requirements at the same time ensuring increased bio-compatibility, recycling, and eventually lower cost. On the other hand, optical 3D printing (O3DP) is a rapid prototyping tool (and an additive manufacturing technique) being developed as a choice for efficient and low waste production method, yet currently associated with mainly petroleum-derived resins. Here we employ a single bio-based resin derived from soy beans, suitable for O3DP in the scales from nano-to macro-dimensions, which can be processed even without the addition of photoinitiator. The approach is validated using both state-of-the art laser nanolithography setup as well as a widespread table-top 3D printer-sub-micrometer accuracy 3D objects are fabricated reproducibly. Additionally, chess-like figures are made in an industrial line commercially delivering small batch production services. Such concept is believed to make a breakthrough in rapid prototyping by switching the focus of O3DP to bio-based resins instead of being restricted to conventional petroleum-derived photopolymers. Bio-based polymers are emerging as replacement for petroleum-derived polymers. The growth of the production and market is 2.05 Mtons of bio-plastics 1 and 700 bilion Euros in Europe only 2. The main advantages of bio-based plastic products compared to the conventional plastics are the preservation of fossil resources by using bio-mass which is a renewable resource and provision of the unique potential of carbon neutrality, as well as bio-degradability of the certain types of bio-plastics which offers additional means of recovery at the end of a product's life 3. The spectrum of bio-based plastics usage varies from nanocomposites 4-8 and films 9-11 to adsorbents 12-14. Vegetable oils are potential starting materials for the preparation of polymers due to their ready availability, inherent bio-degradability, negligible toxicity, and existence of modifiable functional groups 15. Nowadays there are a lot of scientific research dedicated to the light induced polymerization. As there exist diverse technical implementations of this technology, it is known in many names: lithography (stereolithography, digital light processing (DLP)/projection lithography), direct laser writing (DLW) or alternatively laser direct writing (LDW), two-photon polymerization (2PP), nonlinear lithography (NLL), multi-photon lithography (MPL), etc. However, this additive manufacturing process simply can be called by one common name: optical 3D printing (O3DP) as it is based on photons. This rapid prototyping tool is being developed as a choice for efficient and low waste production tool, yet currently associated with mainly petroleum-derived resins 16-19. On the other hand, O3DP in combination with post-processing (thermal-treatment) allows fabrication of free-form structures which can serve as 3D templates f...

“…However, the 3D printing technologies are a paradigm shift that eliminates the complex processes in conventional manufacturing by reducing energy consumption and cost of production, respectively. [11,12] AM is characterised by increased capacity to manufacture a wide range of functional products on market demand more easily due to increased design flexibility. In addition, the manufacturing processes are cost-effective, with reduced waste and blend unique materials needed to improve the performance of the end-product and extend its durability.…”

Introduction: The term 3D printing is commonly used to depict an assembling method whereby the final form of an object is the result of the addition of different layers to build the frame of an object. This procedure is more accurately portrayed as additive manufacturing and is likewise alluded to as fast prototyping. The term 3D printing, in any case, is generally new and has been an active part of current developments in Dentistry. Much publicity encompasses the evolution of 3D printing, which is hailed as an innovation that will perpetually change CAM manufacturing, including in the dental sector. This review is the first part in a 3D Printing series that looks at the history of 3D Printing, the technologies available and reviews the literature relating to the accuracy of these technologies. Conclusions: The recent advancement in digital dentistry to incorporate these tools has modernised dental practices by paving the way for computer-aided design (CAD) technology and rapid prototyping. The use of 3D printing has led to 3D digital models produced with intraoral scanners (IOS), which can be manipulated easily for diagnosis, treatment planning, mockups, and a multitude of other uses. Combining 3D Printing with a 3D intraoral scan eliminates the need for physical storage but makes it to retrieve a 3D models for use within all dental modalities.

Emerging imaging modalities require urgently the use of physical anthropomorphic phantoms. They are used to design, test and evaluate the performance of the new forthcoming imaging systems, prior to their introduction into clinical practice. However, until recently, manufacturing of such phantoms was challenging due to limitations in the current technology, suitable materials, manufacturing precision, and size of digital models. This paper presents the application of three-dimensional (3D) printing in the field of biomedical engineering. Specifically, the focus is on the development of anthropomorphic physical phantoms with characteristics suitable for use in x-ray imaging. The use of 3D printing in the educational process of engineers, doctors and physicists is also demonstrated.
