INTRODUCTION The white-eared opossum, Didelphis albiventris, can be considered an excellent model for comparative embryology in developmental biology studies. The group Metatheria (Didelphimorphia) has relevance among mammals, particularly related to [...] Natural anatomical pieces of wild animals are rare and teachers seek alternatives in satisfactory quantity and quality to inform their students. This article aims to describe the use of multiplanar reconstructions and 3D volume rendering computed tomography (CT) images, rapid prototyping and 3D printing of opossum head to create a biomodel to veterinary education in descriptive anatomy of wild animals. A six-step method study was conducted to construct the biomodel: (1) selection of opossum head from museum; (2) CT scanning of bones structures in veterinary hospital; (3) DICOM visualization medical images in multiplanar reconstructions and 3D volume rendering; (4) .dicom file conversion to. stl; (5) 3D printing of opossum head by rapid prototyping; (6) comparison of 3D model printed with the original anatomical piece. The use of CT images with their different forms of reconstruction can provide a more comprehensive 3D view of opossum craniofacial region and allow a better understanding of head anatomy of this species. The 3D printed biomodel can be a viable alternative to original bone specimens when used in anatomy education. However, further studies must be continued to validate the method in Veterinary Medicine courses. KEY WORDS: Veterinary Education; Anatomy; Biomodel; 3D Printing; Opossum.

RAPID prototyping, INVENTORIES, SPECIFICATIONS, HEURISTIC, and SOCIAL problems
• We present simple techniques for prototyping Parallel Alternating Criteria Search (PACS) into a domain-specific parallel primal MIP heuristic. • Our approach entails specializing PACS to better adapt to the target problem structure. • We showcase its application to two classes of the Maritime Inventory Routing Problem. • We show the adapted heuristic is competitive with state-of-the-art specialized algorithms and MIP solvers. • The modular nature of PACS proves a platform for the rapid prototyping of parallel domain-specific heuristics. Parallel Alternating Criteria Search (PACS) relies on the combination of computer parallelism and Large Neighborhood Searches to attempt to deliver high quality solutions to any generic Mixed-Integer Program (MIP) quickly. While general-purpose primal heuristics are widely used due to their universal application, they are usually outperformed by domain-specific heuristics when optimizing a particular problem class. In this paper, we focus on the fast development of domain-specific parallel primal heuristics. Our approach entails specializing PACS to better adapt to the target problem structure. We showcase its application to two classes of the Maritime Inventory Routing Problem, an important application of MIPs to real world problems. We computationally compare the proposed modified framework with state-of-the art specialized algorithms and MIP solvers. Results show the effectiveness of our approach, and how the modular nature of PACS can provide a platform for the rapid prototyping of parallel domain-specific heuristics. [ABSTRACT FROM AUTHOR]

RAPID prototyping, PROTOTYPES, JOB analysis, INFORMATION resources management, SYSTEMS design, ORGANIZATIONAL change, and CORPORATE culture
This article assesses the effectiveness of the prototyping approach to information systems development. In this investigation of the effectiveness of the prototyping approach, user and designer attitudes are explored through field interviews and a laboratory experiment. The research findings concerning the impact of the prototyping approach on designers and users of information systems provide some insight into the effectiveness of the prototyping approach. A prototyping effort should be undertaken by designers and users who are well informed about the prototyping approach. Prototyping philosophy and plans should be understood by both designers and users. Prototyping is a new approach to information systems development, and like any organizational innovation, it needs a supportive organizational climate. Prerequisites to successful prototyping include technological tools that facilitate fast response to user requests and motivated and knowledgeable users and designers. In summary, the prototyping approach offers an opportunity to achieve favorable user attitudes toward the design process and the information system.
The article informs about WESTEC Long Beach Convention Center event which showcased the latest in machinery, metrology, design, digital innovations, 3D printing, and engineering expertise in California. It mentions how the emerging technologies that are transforming how we design and make things. It further reports that the Complimentary educational sessions included interactive Knowledge Bars, keynote addresses and informative new-product demonstrations.
RAPID prototyping, ENGINEERING design, THREE-dimensional printing, MATERIALS, 3-D printers, and DIGITAL printing presses
An interview with Nadav Goshen, chief executive officer (CEO) of MakerBot Industries, is presented. Topic include the platform was designed for engineers who need immediate access to a 3D printer that can deliver industrial performance but at a significantly lower cost, and also providing engineers with more material options by working with filament suppliers to offer a wider range of materials.

The article informs that rapid prototyping plays a critical role in the development of various consumer products. One might think that with today's high-end computer-aided design systems and high-resolution display screens, a product can be designed and assembled correctly in virtual space, then communicated to a factory and mass-produced at the touch of a button. Product development today always keeps the consumer in mind. In focus groups, ideation groups, and ethnography studies, the invited participants prefer to see and feel real products, not just look at computer-generated images. To refine the feel of a product, its ergonomic aspects must be evaluated, including the position and shape of handgrips, buttons, screens, dials, and ports. The overall development cycle is short. Creating a prototype--or rather a series of prototypes--is critical. Some markets change so quickly that toy makers in particular create two models--one that "works like" and one that "looks like"--before compressing all design considerations and iterations into a single footprint and launching into mass production in late summer.
