Cushioning and antibacterial packaging are the requirements of the storage and transportation of fruits and vegetables, which are essential for reducing the irreversible quality loss during the process. Herein, the composite of carboxymethyl nanocellulose, glycerin, and acrylamide derivatives acted as the shell and chitosan/AgNPs were immobilized in the core by using coaxial 3D-printing technology. Thus, the 3D-printed cushioning–antibacterial dual-function packaging aerogel with a shell–core structure (CNGA/C–AgNPs) was obtained. The CNGA/C–AgNPs packaging aerogel had good cushioning and resilience performance, and the average compression resilience rate was more than 90%. Although AgNPs was slowly released, CNGA/C–AgNPs packaging aerogel had an obvious antibacterial effect on E. coli and S. aureus. Moreover, the CNGA/C–AgNPs packaging aerogel was biodegradable. Due to the customization capabilities of 3D-printing technology, the prepared packaging aerogel can be adapted to more application scenarios by accurately designing and regulating the microstructure of aerogels, which provides a new idea for the development of food intelligent packaging.

The article presents the study of the application of 3D printing technology for rapid tooling in sheet metal forming for custom or small–lot manufacturing. The main issue of the usage of 3D printing technology for die tooling was discovered. It is proposed to use the method of mathematical modelling to investigate how the printing parameters affect the compressive strength of FDM 3D–printed parts. Using expert research methods, the printing parameters most strongly affecting the strength of products were identified for further experiments. A method for testing the strength of 3D–printed materials has been developed and tested.

This project involves the implementation of 3D printing technology on designing and fabricating food holders in the food industry. Food holders are designed to hold the food packages in the filling line for food manufacturing industries that apply retort technology. Therefore, this study aims to implement the 3D printing technology in particular FDM to fabricate food holders for the food processing industry. The approach of using this technology is focused on giving more view on the capability of 3D printing technology, aiming at reducing the overall process fabrication cost and fabrication time. Hence, the fabrication cost and time between FDM and conventional machining methods were compared. This study revealed that Organic Gain food industry was able to reduce the cost and fabrication time for the food holder up to approximately 96.3% and 72% respectively. This project gives an insight into the ability of 3D printing technology in delivering the demands of the industry in producing parts as well as the adaptability of the technology to the industry in new product development. The project was carried out successfully and the 3D printed food holder has been tested and functions smoothly.

Additive-manufacturing is one of the major pillars of the new industrial revolution and the three-dimensional (3D) printing technology has been highlighted in this scenario. Among the many areas benefited by 3D-printing, the development of electrochemical sensors has appeared in evidence in the last years. One potential application of 3D-printed electrochemical sensors is devoted to forensic chemistry, which demands for portable analytical methods that can provide on-site measurements and thus bring a relevant information in loco. In this context, this review highlights the recent contribution of 3D-printing technology on the development of electrochemical sensors with great promises for on-site analysis in “real-world” forensic scenarios. From the detection of trace explosives, gunshot residues, illicit drugs and chemical threats, to the measurement of adulterants in food and fuels, we show the wide range of applications that 3D-printed electrochemical sensors have been proposed and future demands that can be addressed by such a powerful, affordable, and accessible tool.

Background: 3D printing technology is a new chapter in pharmaceutical manufacturing and has gained vast interest in the recent past as it offers significant advantages over traditional pharmaceutical processes. Advances in technologies can lead to the design of suitable 3D printing device capable of producing formulations with intended drug release. Methods: This review summarizes the applications of 3D printing technology in various drug delivery systems. The applications are well arranged in different sections like uses in personalized drug dosing, complex drugrelease profiles, personalized topical treatment devices, novel dosage forms and drug delivery devices and 3D printed polypills. Results: This niche technology seems to be a transformative tool with more flexibility in pharmaceutical manufacturing. Typically, 3D printing is a layer-by-layer process having the ability to fabricate 3D formulations by depositing the product components by digital control. This additive manufacturing process can provide tailored and individualized dosing for treatment of patients different backgrounds with varied customs and metabolism pattern. In addition, this printing technology has the capacity for dispensing low volumes with accuracy along with accurate spatial control for customized drug delivery. After the FDA approval of first 3D printed tablet Spritam, the 3D printing technology is extensively explored in the arena of drug delivery. Conclusion: There is enormous scope for this promising technology in designing various delivery systems and provides customized patient-compatible formulations with polypills. The future of this technology will rely on its prospective to provide 3D printing systems capable of manufacturing personalized doses. In nutshell, the 3D approach is likely to revolutionize drug delivery systems to a new level, though need time to evolve.

In modern world more and more materials with extreme properties are being used: high alloys, high-entropy alloys, nanostructured materials, etc. The extreme properties of these materials make them especially sensitive to hydrogen diffusion. Hydrogen can severely impair their properties and cause failures in structures and machines the material is used in. Nowadays, when structures and components are becoming increasingly complex, the use of 3D printing technology is becoming more widespread. Components made using 3D printing technologies are usually layered, which increase the amount of hydrogen that can diffuse into the material. The amount of hydrogen concentration in 3D printed nickel samples has been determined using vacuum heating method in hydrogen analyzer AV-1. The samples were held at different constant temperatures and the total amount of hydrogen extracted at those temperatures was calculated. A mathematic model was developed to evaluate the amount of hydrogen extracted at a given temperature. The evaluation was then compared to the experiment results, and the validity of the mathematical model and the selected hydrogen activation energies was verified.
