“…In medical applications, the 3D scanning of a human body involved mainly highly rated laser scanners for acquiring the parts of interest, in order to improve diagnosis or to facilitate the creation of 3D printed orthosis or prosthesis (Baronio et al, 2016;Telfer, Woodburn, 2010). This device was used as a tracking system (Wang et al, 2012), for rehabilitation (Lange et al, 2011), for foot orthoses (Dombroski et al, 2014) and for improving the design of leg prosthesis (Colombo et al, 2016) with the aim to find a proper way to acquire 3D data using low cost sensors. On the other hand, recently the Structure Sensor was developed for acquiring 3D data of the environment simply connecting it to an iPhone or an iPad.…”

ABSTRACT:Low-cost 3D sensors are nowadays widely diffused and many different solutions are available on the market. Some of these devices were developed for entertaining purposes, but are used also for acquisition and processing of different 3D data with the aim of documentation, research and study. Given the fact that these sensors were not developed for this purpose, it is necessary to evaluate their use in the capturing process. This paper shows a preliminary research comparing the Kinect 1 and 2 by Microsoft, the Structure Sensor by Occipital and the O&P Scan by Rodin4D in a medical scenario (i.e. human body scans). In particular, these sensors were compared to Minolta Vivid 9i, chosen as reference because of its higher accuracy. Different test objects were analysed: a calibrated flat plane, for the evaluation of the systematic distance error for each device, and three different parts of a mannequin, used as samples of human body parts. The results showed that the use of a certified flat plane is a good starting point in characterizing the sensors, but a complete analysis with objects similar to the ones of the real context of application is required. For example, the Kinect 2 presented the best results among the low-cost sensors on the flat plane, while the Structure Sensor was more reliable on the mannequin parts.

2 ABSTRACTPurpose. The fabrication of a ready-to-use immediate release tablets via 3D printing provides a powerful tool to on-demand individualization of dosage form. This work aims to adapt a widely used pharmaceutical grade polymer, polyvinylpyrrolidone (PVP), for instant on-demand production of immediate release tablets via FDM 3D printing.Methods. Dipyridamole or theophylline loaded filaments were produced via processing a physical mixture of API (10%) and PVP in the presence of plasticizer through hot-melt extrusion (HME). Computer software was utilized to design a capletshaped tablet. The surface morphology of the printed tablet was assessed using scanning electron microscopy (SEM). The physical form of drug and its integrity following an FDM 3D printing were assessed using x-ray powder diffractometry (XRPD), thermal analysis and HPLC. In vitro drug release studies for all 3D printed tablets were conducted in a USP II dissolution apparatus.Results. Bridging 3D printing process with HME in the presence of a thermostable filler, talc, enabled the fabrication immediate release tablets at temperatures as low as 110 o C. The integrity of two models drugs was maintained following HME and FDM 3D printing. XRPD indicated that a portion of the loaded theophylline remained crystalline in the tablet. The fabricated tablets demonstrated excellent mechanical properties, acceptable in-batch variability and an immediate in vitro release pattern. Conclusions.Combining the advantages of PVP as an impeding polymer with FDM 3D printing at low temperatures, this approach holds a potential in expanding the spectrum of drugs that could be used in FDM 3D printing for on demand manufacturing of individualised dosage forms.

Abstract. With the development of the times and social progress, 3D printing technology of our country gradually began to rise, is a kind of rapid prototyping technology in the present stage of our country, has gradually entered people's life, aroused people's interest and attention, and has been in a number of areas for the use of. The important point is that the current mold manufacturing industry is the basis of our national industry, mold manufacturing industry has become an important industry in the national economy of our country, has a very good position. 3D printing technology in the mold manufacturing industry in the application of the degree of deepening and expanding, has become a strong momentum in the future development of our country. The author first analyzes the working principle of 3D printing technology, development advantages and the characteristics of mold industry in the future, and the use of 3D printing technology mold related examples to analyze the specific manufacturing, finally puts forward the existing 3D printing technology problems and future development direction. PrefaceAt this stage, most of our country's products are dependent on the manufacture of mold printing technology, and in the process of industrial production, 60% to 90% of the industrial products need mold processing. With the mold for the processing and manufacturing of products, greatly improved the efficiency of industrial products, and for the final product production and renovation to create a good condition. At present, due to the dependence of the industrial products on the mold, and its mold manufacturing has some limitations, the development of all molds is particularly important. The development of the mold has technical difficulties, and the appearance of the different parts of the mold will also affect the extent of the mold. In general, the more complex the results of the parts, then the more difficult to mold manufacturing. So, can the influence factors of future product development has many aspects, including mold design level, industrial enterprises in manufacturing power, the quality of the mold manufacturing, mold manufacturing and processing equipment quality etc.. Only the effective reduction of the number of mold production, can reduce the cost of the product. 3D printing technology effectively complements the shortcomings of the traditional manufacturing methods, so that the mold manufacturing reform technology has made certain progress[1]. 3D printing technology work principle and characteristic3D printing technology has a special advantage, in the application of 3D printing technology for mold production, no longer the basic situation of the mold into account, especially in the production tool surface is particularly easy to operate. With the development of science and technology, the original material under normal conditions and the properties of materials are able to constantly improve and perfect and supplement, and also can adapt to the traditional manufacturing method, it has a very importan...
