“…With regard to this aspect, the patient has the opportunity to better understand the extent of his pathology, as well as the treatment proposed by the surgeon. A realistic 3D-printed model that reflects the relationship between a lesion and normal structures may be useful in the pre-operative planning for determining the safest surgical strategy, designing patient-specific surgical instruments [2,3] or custom implants that would otherwise unavailable or prohibitive in terms of cost. Finally, the combination of 3D printing technology and biotechnology, using biomaterials, cells, and growth factors, offers the opportunity to fabricate biomedical parts and scaffolds that maximally imitate natural tissue and organ characteristics, starting a new era in regenerative and transplantation medicine, in particular in bone, joint, and ligament reconstruction.…”

This paper presents the application of a low-cost 3D printing technology in pre-operative planning and intra-operative decision-making. Starting from Computed Tomography (CT) scans, we were able to reconstruct a 3D model of the area of interest with a very simple and rapid workflow, using open-source software and an entry level 3D printer. The use of High Temperature Poly-Lactic Acid (HTPLA) by ProtoPasta allowed fabricating sterilizable models, which could be used within the surgical field. We believe that our method is an appealing alternative to high-end commercial products, being superior for cost and speed of production. It could be advantageous especially for small and less affluent hospitals that could produce customized sterilizable tools with little investment and high versatility.

The aim of this article is to apply some design methodologies to define, as a first objective, an optimized technical specification and then, as a second objective, to manage the transition from conceptual design to construction project of an innovative means of urban transport, meeting the needs of ‘renewable energy’ requirements, which then decline into this new urban vehicle formed by a hoverboard and an electric scooter. The first part of the article is focused on the conceptual design of the means by using methodologies such as the Quality Function Deployment (QFD), applied in the first phase of the work to compare some of the most popular electric scooters on the market; we then used a typical method for product marketing, i.e., the decision-making process driven by the analysis of benchmarking, suitable for quantitatively organize competitive analysis and choosing innovation targets; finally, we implemented the top-flop analysis in order to better improve the benchmarking implementation, identifying the best product on the market, basing on the highest number of innovative requirements owned by it, as shown by Frizziero in 2018 and Meuli et al. in 1997. The second part of the article focuses on the project of the kick scooter through the use of a software for the FEA simulation and on the possible realization of the prototype through a suitable connecting component.

The present paper focuses on the recovery of energy from the unitary passage of people inside the turnstiles. Positioned at strategic points such as stadiums, buildings and fairs, the turnstiles are objects that interact with a large number of people, so we decided to take advantage of this peculiarity to get electricity immediately usable [1-3]. The issue of energy sustainability is increasingly discussed in terms of climate change that is undergoing our planet; hence an ever increasing awareness of avoiding energy losses in all phases of everyday life, even in those apparently unimportant. In our case, people do not have to change their habits or gestures during the turnstile approach, what changes is the concept of passing that becomes the protagonist and fundamental to reach our goal [4-5].
