The food packaging sector generates large volumes of plastic waste due to the high demand for packaged products with a short shelf-life. Biopolymers such as starch-based materials are a promising alternative to non-renewable resins, offering a sustainable and environmentally friendly food packaging alternative for single-use products. This article provides a chronology of the development of starch-based materials for food packaging. Particular emphasis is placed on the challenges faced in processing these materials using conventional processing techniques for thermoplastics and other emerging techniques such as electrospinning and 3D printing. The improvement of the performance of starch-based materials by blending with other biopolymers, use of micro- and nano-sized reinforcements, and chemical modification of starch is discussed. Finally, an overview of recent developments of these materials in smart food packaging is given.

Dimensional Printing

We comment on the recent developments and problems of three-dimensional printing in cardiology. Since there are currently no standards or consensuses for 3D printing in clinical medicine and the technology is at its infancy in cardiology, it’s very important to detail the procedures to allow more similar studies to further our understandings of this novel technology. Most studies have employed computed tomography to obtain source data for 3D printing, the use of real-time 3D transesophageal echocardiography for data acquisition remains rare, so it would be very valuable and inspiring to detail the image postprocessing steps, or the reliability of the study results will be doubtful.

Specific Experiment

Computational design allows for architecture with an extraordinary degree of topographical and topological complexity. Limitations of traditional CNC technologies have until recently precluded this architecture from being fabricated. While additive manufacturing has made it possible to materialize these complex forms, this has occurred only at a very small scale. In trying to apply additive manufacturing to the construction of full-scale architecture, one encounters a dilemma: existing large-scale 3D printing methods can only print highly simplified shapes with rough details, while existing high-resolution technologies have limited print spaces, high costs, or material attributes that preclude a structural use. This paper provides a brief background on additive manufacturing technology and presents recent developments in sand-printing technology that overcome current 3D printing restrictions. It then presents a specific experiment, Digital Grotesque project, which is the first application of 3D sand-printing technology at an architecture scale. It describes how this project attempts to exploit the potentials of these new technologies.

Printing Processes

The recent success of additive manufacturing processes (also called, 3D printing) in the manufacturing sector has led to a shift in the focus from simple prototyping to real production-grade technology. The enhanced capabilities of 3D printing processes to build intricate geometric shapes with high precision and resolution have led to their increased use in fabrication of microelectromechanical systems (MEMS). The 3D printing technology has offered tremendous flexibility to users for fabricating custom-built components. Over the past few decades, different types of 3D printing technologies have been developed. This article provides a comprehensive review of the recent developments and significant achievements in most widely used 3D printing technologies for MEMS fabrication, their working methodology, advantages, limitations, and potential applications. Furthermore, some of the emerging hybrid 3D printing technologies are discussed, and the current challenges associated with the 3D printing processes are addressed. Finally, future directions for process improvements in 3D printing techniques are presented.

3D Applications

This paper reviews the recent development of 3D printing of biosamples, in terms of the 3D structure design, suitable printing technology, and available materials. Successfully printed 3D biosamples should possess the properties of high cell viability, vascularization and good biocompatibility. These goals are attained by printing the materials of hydrogels, polymers and cells, with a carefully selected 3D printer from the categories of inkjet printing, extrusion printing and laser printing, based on the uniqueness, advantages and disadvantages of these technologies. For recent developments, we introduce the 3D applications of creating scaffolds, printing cells for self-assembly and testing platforms. We foresee more bio-applications of 3D printing will be developed, with the advancements on materials and 3D printing machines.

Background: Recent developments in 3D printing have gave orthopedic surgeons among a novel technology that has the ability to revolutionize preoperative planning. The appearance of 3D printing technology (3DPT) enables the digital preoperative plan & simulation to move from the virtual phase to the reality phase. Numerous fields of medicine are lately benefiting from the operate of 3D printing, including the arising part of 3D printing in orthopedic surgery. Methods: We searched on PubMed and Google Scholar databases in January 2020 to find papers and studies about using 3D printing in orthopedy for aim of preplanning. The key words for search were (“3D printing” OR “3D-printed Model” OR “three-dimensional Printer”) AND (“Orthopedy” OR “Orthopedics” OR “Orthopedics”) AND (“Surgery” OR “Operation”) AND (“Pre-planning” OR “Plan”) AND (“Fracture” OR “Trauma”) that we used compound. We exclude the papers which their titles or abstracts were not relevant. At last, we select the most related papers to use in this article. Results: The search on PubMed found 80 Papers and on Google Scholar found 104 papers. After excluding similar and unrelated papers, 44 papers were selected for this review article. Conclusion: Almost all studies have shown us that using a 3D model can have a very positive effect on the surgical process and its outcomes, as well as patient and surgeon satisfaction. Therefore, we anticipate that this technology will be used in many orthopedic surgeries in the near future.
