Résumé :

With the fast growth of the market forMEMS (Micro-Electro-Mechanical Systems) devices, Computer-Aided Design (CAD) and Computer-Aided Process Planning (CAPP) systems for MEMS are essential for the appropriate division of labor between MEMS design and fabrication. Although several CAD systems for MEMS devices are commercially available, CAPP systems for MEMS are still underdeveloped, and few systems have been investigated. The purpose of this study is to prototype a CAPP system for MEMS for non-expert MEMS designers. MEMS device geometry, a complex layered structure made of multiple materials, is represented as a solid model called a device model. The system has twomain functions. In processextraction function, all feasible fabrication processes of the device are exhaustively derived from the device model using 3D fabrication features as clues. In manufacturable-geometry-estimation function, the expected 3D geometry of the device that will actually be fabricated by the derived process, which might differ from the original device model, is estimated. Process emulation using a commercial emulator and examination by expert researchers confirm that the derived process plans and the expected 3D geometries of the device are feasible and plausible.

Résumé :

3D printing is an attractive method to fabricate microfluidic devices due to (1) its fast and simple process without specialized equipment and cleanroom environment, and (2) its capability to create complex 3D structures. Combined with Polydimethylsiloxane (PDMS), it can be used to develop various microfluidic devices taking advantage of both 3D printing and PDMS. In this paper, we investigated a Digital Light Processing (DLP) 3D printer to fabricate 3D printing/PDMS integrated microfluidic devices. We used it to fabricate both a master mold for the PDMS process and a substrate containing pneumatic ports and channels. The optimal design parameters to print a symmetrical microchannel structure were determined. We also measured the printing accuracy of taper structures as an example of its capability to fabricate complex structures. Then, we fabricated a microfluidic device by integrating a PDMS component with a 3D printed substrate. The microfluidic device operation was demonstrated using dye solutions. The fluidic control results clearly show the microfluidic device works as expected.

Résumé :

ABSTRACTDetection of volatile organic compounds (VOCs) emitted from cancerous tumor cells in exhaled human breath allows for early diagnosis of various types of cancers. 3D graphene with a large surface area is considered a suitable material for creating novel sensitive VOCs sensors. In this study, 3D graphene and 3D graphene oxide were synthesized from graphene oxide suspension, hydroquinone and formaldehyde by employing polymerization and reduction. The capability of VOC gas sensing was evaluated by measuring the electrical current response in flowing N2 gas over a range of concentrations of acetone or 1-butanol at room temperature. It was observed that the device current correlated well with the VOC concentration. The adsorption of acetone decreased the current, but the adsorption of 1-butanol increased the current during sensing. 3D graphene oxide device was more sensitive than 3D graphene device because of the high concentration of oxygen-containing functional groups on the surface. These results indicated that 3D graphene and 3D graphene oxide may be the suitable materials for VOCs sensing devices.

Résumé :

This work presents a new architecture concept for microfluidic devices, which combines the conventional 3D printing fabrication process with the stable and precise integration of polymeric functional materials in small footprints within the microchannels in well-defined locations. The approach solves the assembly errors that normally occur during the integration of functional and/or sensing materials in hybrid microfluidic devices. The method was demonstrated by embedding four pH-sensitive ionogel microstructures along the main microfluidic channel of a complex 3D printed microfluidic device. The results showed that this microfluidic architecture, comprising the internal integration of sensing microstructures of diverse chemical compositions, highly enhanced the adhesion force between the microstructures and the 3D printed microfluidic device that contains them. In addition, the performance of this novel 3D printed pH sensor device was investigated using image analysis of the pH colour variations obtained from photos taken with a conventional camera. The device presented accurate and repetitive pH responses in the 2 to 12 pH range without showing any type of device deterioration or lack of performance over time.

Résumé :

Abstract Recent advances in additive manufacturing enable redesigning material morphology on nano-, micro-, and meso-scale, for achieving an enhanced functionality on the macro-scale. From non-planar and flexible electronic circuits, through biomechanically realistic surgical models, to shoe soles individualized for the user comfort, multiple scientific and technological areas undergo material-property redesign and enhancement enabled by 3D printing. Fiber-device technology is currently entering such a transformation. In this paper, we review the recent advances in adopting 3D printing for direct digital manufacturing of fiber preforms with complex cross-sectional architectures designed for the desired thermally drawn fiber-device functionality. Subsequently, taking a recursive manufacturing approach, such fibers can serve as a raw material for 3D printing, resulting in macroscopic objects with enhanced functionalities, from optoelectronic to bio-functional, imparted by the fiber-devices properties.

Résumé :

Objective. The aim of this study is to present a 3-dimensional (3D)-printed device to simply perform abdominal enterostomy and colostomy. Summary Background Data. Enterostomy and colostomy are frequently performed during abdominal surgery. 3D-printed devices may permit the creation of enterostomy easily. Methods. The device was designed by means of a CAD (computer-aided design) software, Rhinoceros 6 by MC Neel, and manufactured using 3D printers, Factory 2.0 by Omni 3D and Raise 3D N2 Dual Plus by Raise 3D. Colostomy was scheduled on a human cadaver and on 6 Pietrain pigs to test the device and the surgical technique. Results. The test on the cadaver showed that the application of the device was easy. Test on porcine models confirmed that the application of the device was also easy on the living model. The average duration of the surgical procedure was 32 minutes (25-40 minutes). For the female pigs, return to full oral diet and recovery of a normal bowel function was observed at postoperative day 2. The device fell by itself on average on the third day. Until day 10, when euthanasia was practiced, the stoma mucosa had a good coloration indicating a perfect viability of tissues. No complications were observed. Conclusions. This is the first study that describes the use of a 3D-printed device in abdominal surgery. End-type colostomy using a 3D-printed device can be safely and easily performed in an experimental porcine model, without postoperative complications. Further studies are needed to evaluate its utility in the clinical setting.

Résumé :

Based on binocular vision the human eye is capable of generating the observed spatial perception of the object. Nowadays 3D imaging of two-dimensional surface is in vogue especially in the cinema industry. However, 3D imaging is gradually getting into other industries especially in other parts of everyday life (advertisements, presentations, entertainment ...). 3D images can be created in various ways, some of which are detailed in this master´s thesis. This thesis deals with the description and the drawing up of a 3D display which provides a three-dimensional image without using auxiliary objects such as glasses. The display unit produces a three-dimensional image at a fundamental level, which consists of providing high-speed rotation of the display and creates the current portion of the object in specified sections.

Résumé :

Manipulating 3D objects on a tabletop computer is inherently problematic. The flat surface of tabletop computers enable natural 2D interaction, but lack the additional dimension needed to intuitively facilitate 3D object manipulation. In this thesis I present TZee, a passive tangible widget that enables natural interactions with 3D objects by exploiting the lighting properties of diffuse illumination (DI) multi-touch tabletops. The Tangible User Interface (TUI), TZee is constructed from several pieces of stacked acrylic glass. The stacked glass enables TZee to channel the light emitted from the tabletop slightly higher above the surface without major light loss. This technique allows the tangible interface to transmit touches on the device to the tabletop without any supplementary power. TZee enables simple translation, rotation and scaling along the x, y, or z axes. This thesis discusses several important design considerations of TZee, demonstrated TZee’s value though several applications and a gesture design study.

Résumé :

Se ha desarrollado un sistema innovador de cocción de alimentos basado en el calentamiento por radiación infrarroja (IR) mediante un láser de CO2 (IR Láser CO2) teniendo en cuenta que el agua posee una elevada capacidad de absorción electromagnética en la longitud de onda del IR Láser CO2. El sistema de cocción se ha adaptado en una impresora 3D de alimentos y se ha diseñado con los siguientes requerimientos: 1) cocción en un área delimitada; 2) capacidad de control de la temperatura de cocción; 3) las dimensiones físicas de la lámpara de CO2 deben adaptarse a la impresora 3D de alimentos; 4) el consumo de energía debe ser compatible con la capacidad de la impresora 3D de alimentos; 5) el sistema debe ser controlado por software; 6) versatilidad para cocinar mientras se imprime el alimento o después de la impresión. En el presente estudio se han usado dos sistemas de cocción por IR Láser CO2. Primero se usó una grabadora y cortadora con IR Láser CO2 en la que se establecieron unas condiciones específicas que permitieron la cocción de hamburguesas de ternera, puré de patatas y masas de pizza. Después se desarrolló un nuevo sistema de cocción integrado en la impresora 3D de alimentos formado por una lámpara láser de CO2, un sistema de galvos para dirigir el haz láser a la zona de cocción y un software que permitía controlar la posición y frecuencia del movimiento de los galvanómetros. Con este nuevo sistema se podía cocinar de manera homogénea un área determinada, debido al rápido movimiento de los espejos de los galvos. Se cocinaron los siguientes alimentos en el interior de la impresora 3D de alimentos: hamburguesas de carne de ternera; preparados vegetales tipo hamburguesas formuladas con legumbres, hortalizas y huevo como ingredientes principales; y bases de pizza. Para demostrar que la cocción fue adecuada y suficiente, la cocción mediante IR Láser CO2 se comparó con diferentes sistemas de cocción tradicionales (plancha, barbacoa y hornos IR, de convección, de suela refractaria y microondas) y se evaluaron las características microbiológicas, físico-químicas y sensoriales de los alimentos cocidos. Se analizó la formación de hidrocarburos aromáticos policíclicos con el fin de evaluar la seguridad toxicológica, y se estudió el efecto térmico en la eliminación de Salmonella Typhimurium, Salmonella Senftenberg y Escherichia coli O157:H7 inoculadas en las hamburguesas de ternera y en los preparados vegetales. Los análisis microbiológicos y toxicológicos demostraron que los alimentos cocinados con el nuevo sistema IR Láser CO2 son tan seguros como los cocinados con los métodos convencionales. Los análisis sensoriales indicaron que la preferencia de los consumidores 12 por los alimentos cocidos con IR Láser CO2 fue igual o superior a la preferencia por los alimentos cocidos con los sistemas convencionales. Además, se desarrolló un modelo numérico basado en la dinámica computacional de fluidos para simular el proceso de cocción de las hamburguesas de ternera y los preparados vegetales y se validó con los resultados experimentales de aumento de temperatura durante el proceso de cocción. Los resultados numéricos de la evolución de la temperatura coincidieron con los datos experimentales, excepto durante los primeros minutos de la cocción. El modelo de simulación numérico se considera una potente herramienta para optimizar el proceso de cocción del sistema IR Láser CO2. A partir de los resultados obtenidos se abren nuevas vías de trabajo, que incluyen estudios de cocción con alimentos de composición sensiblemente diferente a los probados hasta el momento; la simulación del proceso de cocción con diferentes parámetros y estrategias de cocción; y la realización de estudios nutricionales.
An innovative cooking system based on infrared radiation (IR) using a CO2 laser (CO2 IR Laser) has been developed considering that water absorbance of electromagnetic infrared radiation at CO2 laser wavelength is very high. The new cooking system has been adapted into a 3D food printer and has been designed with the following requirements: 1) ability to cook in a delimited area; 2) control of the cooking temperature; 3) physical dimensions that fit inside the 3D Food Printer; 4) energy consumption below the power supply limits; 5) software-controlled system; 6) versatility to cook while printing the food or to cook once the food is printed. In the present study, two CO2 IR Laser cooking systems have been used and tested. The first CO2 IR Laser cooking system studied was a laser engraver and cutter equipment in which specific conditions were applied to cook beef burgers, mashed potatoes bites and pizza dough. After, a new cooking system adapted to the 3D food printer was developed, consisting of a CO2 laser lamp, a system of galvo mirrors that direct the laser beam to the cooking area, and a software that allowed controlling the position and the frequency of movement of galvanometers. With this new system, a chosen area could be homogenously cooked, due to the rapid movement of the galvo mirrors. The food products cooked inside the 3D food printer were: beef burgers; vegetarian patties prepared with legumes, vegetables and egg as main ingredients; and pizza dough. To demonstrate that cooking had been achieved, food products were cooked with the CO2 IR laser systems and different traditional cooking systems (flat and barbeque grills; IR, convection, desk and microwave ovens). Microbiological, physico-chemical and sensory characteristics of the cooked foods were evaluated. The formation of polycyclic aromatic hydrocarbons was analyzed in beef burgers and pizzas to evaluate toxicological safety, and the thermal effect in the count reduction or survival of Salmonella Typhimurium, Salmonella Senftenberg and Escherichia coli O157:H7 inoculated in beef burgers and vegetarian patties was studied. Microbiological and toxicological analyses showed that food products cooked with the new CO2 IR Laser system were as safe as food cooked with traditional methods. Sensory analyses showed that consumers had the same, or even higher, level of preference for foods cooked with CO2 IR laser system in comparison with foods cooked with traditional methods. In addition, a numerical model based on computational fluid dynamics was developed to simulate the cooking process of beef burgers and vegetarian patties, and it was validated with experimental data of temperature evolution during the cooking process. The numerical results for temperature evolution given by the model coincide with the experimental data, except for the first minutes of cooking. The numerical simulation model is a powerful tool to optimize the cooking process of the CO2 IR Laser system. Based on the results obtained, future work will be carried out including cooking experimental studies with foods containing a significantly different composition; the simulation of the cooking process with different parametric conditions; and nutritional studies.

Anemia affects about 25% of the world’s population and causes roughly 8% of all disability cases. The development of an affordable point-of-care (POC) device for detecting anemia could be a significant for individuals in underdeveloped countries trying to manage their anemia. The objective of this study was to design and fabricate a 3D printed, low cost microfluidic mixing chip that could be used for the diagnosis of anemia. Microfluidic mixing chips use capillary flow to move fluids without the aid of external power. With new developments in 3D printing technology, microfluidic devices can be fabricated quickly and inexpensively. This study designed and demonstrated a passive microfluidic mixing chip that used capillary force to mix blood and a hemoglobin detecting assay. A 3D computational fluid dynamic simulation model of the chip design showed 96% efficiency when mixing two fluids. The mixing chip was fabricated using a desktop 3D printer in one hour for less than $0.50. Blood samples used for the clinical validation were provided by The University of Kansas Medical Center Biospecimen Repository. During clinical validation, RGB (red, green, blue) values of the hemoglobin detection assay color change within the chip showed consistent and repeatable results, indicating the chip design works efficiently as a passive mixing device. The anemia detection assay tended to overestimate hemoglobin levels at lower values while underestimating them in higher values, showing the assay needs to go through more troubleshooting.

Résumé :

To investigate the topic of intuitive interaction using a 3D-device, a toy car was used as a controller with the Stylaero Board to complete one lap in a car racing game. 20 participants completed the task in 2 conditions, one using the 3D-device as a controller, and one using a standard computer keyboard. The interaction was evaluated using task completion time as a measure of learnability of the device, as well as through subjective reactions from users gathered from a tailored questionnaire with 7 statements rated on a Likert scale of 1-5, and 3 open-ended questions. The performance and attitude towards the 3D-device as a controller was compared to the performance and attitude towards using a standard keyboard. The mean task completion time was significantly lower when using the keyboard. A subscale of the enjoyability of using the device was compared between conditions indicating a significant difference where the 3D-device was rated higher than the keyboard. Furthermore, a significant correlation was found between attitude towards the control device and task completion time in the keyboard, while no significant correlation was found between the corresponding variables for the 3D-device. These results indicate a difference between what aspects are important to users when evaluating a new interface compared to a familiar one. The subjective reactions gathered from the open-ended questions were categorized and sorted into themes using thematic analysis to illustrate the various aspects that were highlighted by users for each interface. The problems faced by participants when using the 3D-device were observed and analyzed in relation to current theories of intuitive interaction to find the driving factors of interaction with a new device.

Résumé :

The study of cells chemotaxis and angiogenesis phenomena plays a signiﬁcant role in a better understanding of cancer evolution. As a matter of fact, cells are inﬂuenced by the physiological environment, which contains all the substances that could inﬂuence their regular life. The importance of the study of the impact nutrients or toxic elements may have is generally accepted. In fact, in the last decade a large number of studies were carried on simple 2D devices. However, this type of platform did not allow a well-simulated physiological behavior, and they were soon replaced with the study of 3D platforms. This thesis reports the fabrication, simulation and testing of a 3D microﬂuidic circuit to study cells chemotaxis in a platform where reagents concentration is controlled spatially and temporally. In the ﬁrst part of the thesis all the technologies and processes used for the device manufacturing are listed and explained (Chapter 1). Then, an overview of the biological and physics phenomena that occur during the device usage is reported (Chapter 2). The main part of the work is focused on the experimental fabrication processes (Chapter 3) and simulations and tests for the correct device behavior (Chapter 4). In these sections, all the steps and alternatives in the fabrication process are explained, coming to the ﬁnal correct device production with PDMS casting in situ process with a SU8 photoresist mold; afterward, all the simulations and tests are reported in order to analyze the device: the static and dynamic regimes are analyzed and tested, from the ﬂuorescence method (in order to check if the gradient is correctly maintained) to some biological tests for the cells growth. Finally, conclusions and future perspectives are reported (Chapter 5).

Résumé :

The project evaluates how well a haptic device can be used to interact with a visualization of volumetric data. Since the interface to the haptic device require explicit surface descriptions, triangles had to be constructed from the volumetric data. The algorithm used to extract these triangles is marching cubes. The triangles produced by marching cubes are then transmitted to the haptic device to enable the force feedback. Marching cubes was suitable for parallelization and it was executed using OpenCL. Graphs in the report shows how this parallelization ran almost 70 times faster than the sequential CPU counterpart of the same algorithm. Further development of the project would give medical students the opportunity to practice difficult procedures on a simulation instead of a real patient. This would give a realistic and accurate simulation to practice on.
Projektet går ut på att utvärdera hur väl en haptisk utrustning går att använda för att interagera med en visualisering av volumetrisk data. Eftersom haptikutrustningen krävde explicit beskrivna ytor, krävdes först en triangelgenerering utifrån den volymetriska datan. Algoritmen som används till detta är marching cubes. Trianglarna som producerades med hjälp av marching cubes skickas sedan vidare till den haptiska utrustningen för att kunna få gensvar i form av krafter för att utnyttja sig av känsel och inte bara syn. Eftersom marching cubes lämpas för en parallelisering användes OpenCL för att snabba upp algoritmen. Grafer i projektet visar hur denna algoritm exekveras upp emot 70 gånger snabbare när algoritmen körs som en kernel i OpenCL istället för ekvensiellt på CPUn. Tanken är att när vidareutveckling av projektet har gjorts i god mån, kan detta användas av läkarstuderande där övning av svåra snitt kan ske i en verklighetstrogen simulering innan samma ingrepp utförs på en individ.

Résumé :

We are interested in supporting users in a real world application, that of troubleshooting malfunctioning office devices, such as printers or copiers. Basing upon findings from case studies of troubleshooting activities that we conducted, we are constructing a Mixed Reality troubleshooting system. The system allows end-users to try to solve the problem they are experiencing with the device by themselves, with online support available on the device, or by collaborating with a remote troubleshooter. The architecture of the system is centered on a 3D representation of the device augmented with status data of the actual device coming from its internal sensors. The 3D representation is provided to the end-users on the device screen and to the remote troubleshooters on their desktops and it offers a number of means to interact with it providing help for troubleshooting the device. The main purpose of this paper is to illustrate a new interaction mode with the virtual representation for the end-users that we are designing for our system and that is based on the use of a detachable device screen.

Résumé :

Nowadays one of the most popular trends in software development is Augmented Reality (AR). AR applications offer an interactive user experience and engagement through a real-world environment. AR application areas include archaeology, architecture, business, entertainment, medicine, education and etc. In the paper we compared the main SDKs for the development of a marker-based AR apps and 3D modeling freeware computer programs used for developing 3D-objects. We presented a concept, design and development of AR application “Art-Heritage’’ with historical monuments and buildings of Crimean Tatars architecture (XIII-XX centuries). It uses a smartphone or tablet to alter the existing picture, via an app. Using “Art-Heritage’’ users stand in front of an area where the monuments used to be and hold up mobile device in order to see an altered version of reality.

Résumé :

Rapid development of modern technology and its increasing complexity make high demands to the quality of training of its users. Among others, an important class is vehicles, both civil and military. In the teaching of associated subjects, the accepted hierarchy of teaching aids includes common visual aids (posters, videos, scale models etc.) on the first stage, followed by simulators ranging in complexity, and finished at real vehicles. It allows achieving some balance between cost and efficiency by partial replacement of more expensive and elaborated aids with the less expensive ones. However, the analysis of teaching experience in the Military Institute of Armored Forces of National Technical University “Kharkiv Polytechnic Institute” (Institute) reveals that the balance is still suboptimal, and the present teaching aids are still not enough to allow efficient teaching. This fact raises the problem of extending the range of available teaching aids for vehicle-related subjects, which is the aim of the work. Benefiting from the modern information and visualization technologies, we present a new teaching aid that constitutes a spherical (360° or 3D) photographic panorama and a Virtual Reality (VR) device. The nature of the aid, its potential applications, limitations and benefits in comparison to the common aids are discussed. The proposed aid is shown to be cost-effective and is proved to increase efficiency of training, according to the results of a teaching experiment that was carried out in the Institute. For the implementation, a tight collaboration between the Institute and an IT company “Innovative Distance Learning Systems Limited” was established. A series of panoramas, which are already available, and its planned expansions are presented. The authors conclude that the proposed aid may significantly improve the cost-efficiency balance of teaching a range of technology subjects.

Résumé :

The impacts of Harmful Algal Blooms (HAB), often caused by cyanobacteria (Figure 1), on water resources are increasing. Innovative solutions for treatment of HABs and their associated toxins are needed to mitigate these impacts and decrease risks without introducing persistent legacy contaminants that cause collateral ecosystem impacts. This technical note (TN) identifies novel opportunities enabled by Additive Manufacturing (AM), or 3D printing, to produce high surface area advanced material composites to rapidly prototype sustainable environmental solutions for aquatic nuisance species control. This innovative research explores deployment of 3D-printable polymer composite structures containing nano-scale photocatalysts for targeted open water treatment of HABs that are customizable to the site-of-concern and also retrievable, reusable, and sustainable. The approach developed to control cyanobacteria HAB events has the potential to augment or replace broadcast, non-specific chemical controls that otherwise put non-target species and ecological resources at long-term risk. It can also augment existing UV-treatment HAB treatment control measures. The expected research outcome is a novel, effective, and sustainable HAB management tool for the US Army Corps of Engineers (USACE) and resource managers to deploy in their HAB rapid response programs. The research will provide a framework for scale-up into other manufacturing methods (e.g., injection molding) to produce the devices in bulk (quickly and efficiently). Research for this project title “Mitigation of Harmful Algal Bloom Toxins using 3D Printed Photocatalytic Materials (FY21-23)” was sponsored by the US Army Engineer Research Development Center’s (ERDC) Aquatic Nuisance Species Research Program (ANSRP).
