The influence of business model on the development of 3D food printing technology for dysphagia patients in elderly care

Dysphagia, or difficulty swallowing, affects 10–30 % of persons above 65 years old. Texture-modified, easy-to-swallow, puree-like food in the form of timbales is usually served to this group of patients. Due to the characteristics of timbale, its appearance only remotely reminds of the original ingredients, leading to reduced appetite, reduced nutrition intake, and even malnutrition. 3D food printing of timbales can potentially preserve dysphagia patients’ quality of life and prevent undernourishment by producing more realistic and aesthetically pleasing food. 3D food printing of timbales is however challenging: creation and industrialization of food formulations adapted to the 3D food printing process; speed, hygiene, and reliability of the 3D food printers, etc. In a research project in the context of Swedish elderly care, both technological and economical aspects were investigated. This paper uncovers that the business model dominating the 3D food printing industry is not suitable for this particular market segment. This paper presents several business model alternatives and shows that the choice of the business model will influence and guide the further technological development of timbale printing. The paper also outlines to which extent these findings can be applied to other countries and to similar markets where AM has not taken off or has not been widely adopted

Safety and Quality Improvement of Street Food Packaging Design Using Quality Function Deployment

Product packaging show product detail and characteristics and can influence consumer desire. A well-packaged product, when seen or felt, improves product perception and attitude. In Yogyakarta, fried meatballs are popular street food. Customers often complain about packaging post-purchase. Customers have often complained about the packaging and the common concerns are hot to touch and easily damaged packaging. This study proposes to study the effect of consumer perception and attractiveness of the fried meatballs by improving the packaging. The Quality Function Deployment (QFD) technique was used during the designing phase to study consumer behaviour and desire to create attractive product packaging in line with customer expectations. Survey results indicated eight significant characteristics for fried meatball packaging. Those are an attractive design, oil resistance, heat resistance, easy-to-handle packaging, durable material, food-grade packaging, environmental friendliness, and practical carrying ability. The eight attributes were translated to five using QFD methodology and these five attributes are used as reference points for the development of better packaging. These five attributes of packaging design are heat resistance, oil resistance, food-grade material, environmental friendliness, and not easy to tear. SolidWorks software was used to create 3D models. The design process was controlled to achieve the House of Quality (HOQ) target for consumer desire

Development and evaluation of automated localization and reconstruction of all fruits on tomato plants in a greenhouse based on multi-view perception and 3D multi-object tracking

Accurate representation and localization of relevant objects is important for robots to perform tasks. Building a generic representation that can be used across different environments and tasks is not easy, as the relevant objects vary depending on the environment and the task. Furthermore, another challenge arises in agro-food environments due to their complexity, and high levels of clutter and occlusions. In this paper, we present a method to build generic representations in highly occluded agro-food environments using multi-view perception and 3D multi-object tracking. Our representation is built upon a detection algorithm that generates a partial point cloud for each detected object. The detected objects are then passed to a 3D multi-object tracking algorithm that creates and updates the representation over time. The whole process is performed at a rate of 10 Hz. We evaluated the accuracy of the representation on a real-world agro-food environment, where it was able to successfully represent and locate tomatoes in tomato plants despite a high level of occlusion. We were able to estimate the total count of tomatoes with a maximum error of 5.08% and to track tomatoes with a tracking accuracy up to 71.47%. Additionally, we showed that an evaluation using tracking metrics gives more insight in the errors in localizing and representing the fruits.Comment: Pre-print, article submitted and in review proces

An overview of natural polymers as reinforcing agents for 3D printing

Three-dimensional (3D) printing, or additive manufacturing, is a group of innovative technologies that are increasingly employed for the production of 3D objects in different fields, including pharmaceutics, engineering, agri-food and medicines. The most processed materials by 3D printing techniques (e.g., fused deposition modelling, FDM; selective laser sintering, SLS; stereolithography, SLA) are polymeric materials since they offer chemical resistance, are low cost and have easy processability. However, one main drawback of using these materials alone (e.g., polylactic acid, PLA) in the manufacturing process is related to the poor mechanical and tensile properties of the final product. To overcome these limitations, fillers can be added to the polymeric matrix during the manufacturing to act as reinforcing agents. These include inorganic or organic materials such as glass, carbon fibers, silicon, ceramic or metals. One emerging approach is the employment of natural polymers (polysaccharides and proteins) as reinforcing agents, which are extracted from plants or obtained from biomasses or agricultural/industrial wastes. The advantages of using these natural materials as fillers for 3D printing are related to their availability together with the possibility of producing printed specimens with a smaller environmental impact and higher biodegradability. Therefore, they represent a “green option” for 3D printing processing, and many studies have been published in the last year to evaluate their ability to improve the mechanical properties of 3D printed objects. The present review provides an overview of the recent literature regarding natural polymers as reinforcing agents for 3D printing

A Meticulous Food Safety Plan Today Avoids Handcuffs Tomorrow

In August 2010, thousands of people across the United States were poisoned by eating eggs unknowingly tainted with Salmonella enteritidis bacteria. Following a lengthy investigation, the owners of the facility where the outbreak began were sentenced to three months in prison. This is not a one-off case; poor food safety practices are responsible for several outbreaks and often end in incarceration. Filthy hen houses, diseased fruit storage, and negligent food processing may be the last thing we want to imagine, but these practices have much to teach today\u27s food producers. This article first examines how poor food production practices can lead to an environment ripe for spread of disease and an unacceptable level of contamination. Then, it explores what companies can do to prevent such unacceptable conditions, decrease the likelihood and severity of an outbreak and, of course, avoid incarceration

The Uneasy Case for the Affordable Care Act

The constitutionality of the Affordable Care Act is sometimes said to be an easy question, with the Act\u27s opponents relying more on fringe political ideology than mainstream legal arguments. This essay disagrees. While the mandate may win in the end, it won\u27t be easy, and the arguments against it sound in law rather than politics. Written to accompany and respond to Erwin Chemerinsky\u27s essay in the same symposium, this essay argues that each substantive defense of the mandate is subject to doubt. While Congress could have avoided the issue by using its taxing power, it chose not to do so. Congress has power to regulate commerce among the several States, but that might not extend to every individual decision involving economic considerations -- walking rather than taking the bus, stargazing rather than renting movies, or carrying a gun in a school zone rather than hiring private bodyguards. Even the necessary-and-proper power, the strongest ground for the mandate, may stop short of letting Congress claim extraordinary powers to fix the problems created by its exercise of ordinary ones. Because the mandate\u27s opponents can find some support in existing doctrines, a decision striking down the mandate needn\u27t be a drastic break from past practice. By contrast, a decision upholding the mandate would raise serious questions about the limits of Congress\u27s powers. To many, these questions offer good reasons for doubting whether existing doctrine gets it right -- reasons having more to do with constitutional theory than political preference

3-D Printed Protective Equipment during COVID-19 Pandemic

While the number of coronavirus cases from 2019 continues to grow, hospitals are reporting shortages of personal protective equipment (PPE) for frontline healthcare workers. Furthermore, PPE for the eyes and mouth, such as face shields, allow for additional protection when working with aerosols. 3-D printing enables the easy and rapid production of lightweight plastic frameworks based on open-source data. The practicality and clinical suitability of four face shields printed using a fused deposition modeling printer were examined. The weight, printing time, and required tools for assembly were evaluated. To assess the clinical suitability, each face shield was worn for one hour by 10 clinicians and rated using a visual analogue scale. The filament weight (21-42 g) and printing time (1:40-3:17 h) differed significantly between the four frames. Likewise, the fit, wearing comfort, space for additional PPE, and protection varied between the designs. For clinical suitability, a chosen design should allow sufficient space for goggles and N95 respirators as well as maximum coverage of the facial area. Consequently, two datasets are recommended. For the final selection of the ideal dataset to be used for printing, scalability and economic efficiency need to be carefully balanced with an acceptable degree of protection

Where Should We Place LiDARs on the Autonomous Vehicle? - An Optimal Design Approach

Autonomous vehicle manufacturers recognize that LiDAR provides accurate 3D views and precise distance measures under highly uncertain driving conditions. Its practical implementation, however, remains costly. This paper investigates the optimal LiDAR configuration problem to achieve utility maximization. We use the perception area and non-detectable subspace to construct the design procedure as solving a min-max optimization problem and propose a bio-inspired measure -- volume to surface area ratio (VSR) -- as an easy-to-evaluate cost function representing the notion of the size of the non-detectable subspaces of a given configuration. We then adopt a cuboid-based approach to show that the proposed VSR-based measure is a well-suited proxy for object detection rate. It is found that the Artificial Bee Colony evolutionary algorithm yields a tractable cost function computation. Our experiments highlight the effectiveness of our proposed VSR measure in terms of cost-effectiveness configuration as well as providing insightful analyses that can improve the design of AV systems.Comment: 7 pages including the references, accepted by International Conference on Robotics and Automation (ICRA), 201
