Architecture And Design

In the last few years, digital modelling techniques have played a major role in architecture and design, influencing, at the same time, the creative process and the fabrication of objects. This revolution has produced a new productive generation of architects and designers focused on the expanding possibilities of material and formal production, reinforcing the idea of architecture as an interaction between art and artisanship. This original perspective inspires this paper, which illustrates the contemporary scenario and provides some practical guidance about tools and technologies the designers most often use for creating geometric sculptures with 3D printing. Creative possibilities of topological mesh modelling are used to generate complex geometries from regular polyhedra. This process explores how combining different geometric operations can activate architectural inquiry and generate fascinating shapes with creative flexibility.

Three-dimensional (3D) printing techniques have revolutionized the field of tissue engineering. This is especially favorable to construct intricate tissues such as liver, as 3D printing allows for the precise delivery of biomaterials, cells and bioactive molecules in complex geometries. Bioinks made of polymers, of both natural and synthetic origin, have been very beneficial to printing soft tissues such as liver. Using polymeric bioinks, 3D hepatic structures are printed with or without cells and biomolecules, and have been used for different tissue engineering applications. In this review, with the introduction to basic 3D printing techniques, we discuss different natural and synthetic polymers including decellularized matrices that have been employed for the 3D bioprinting of hepatic structures. Finally, we focus on recent advances in polymeric bioinks for 3D hepatic printing and their applications. The studies indicate that much work has been devoted to improvising the design, stability and longevity of the printed structures. Others focus on the printing of tissue engineered hepatic structures for applications in drug screening, regenerative medicine and disease models. More attention must now be diverted to developing personalized structures and stem cell differentiation to hepatic lineage.

There is growing interest in adopting three-dimensional virtual environments within spatial design courses to use digital modelling techniques to support students' learning. One pedagogical issue that has received little attention so far is the question of how 3D virtual environments can be used to implement assessment techniques that support students' learning of spatial design expertise. This chapter seeks to assist spatial design educators who are considering digital modelling by presenting two case studies that highlight assessment practices within spatial design courses using virtual environments. Rubrics and student work samples are included. These courses both involve students creating architectural designs within virtual environments, yet contrast in several ways: learning outcomes, 3D modelling technologies, and student cohorts. The cases examine how the affordances of virtual environments for iterative, immersive, and collaborative design can enable formative and summative assessment, with both design process and the final artefact playing important roles.

3D printing is a common resource within the architecture and design disciplines in higher education. As is the case with all tools, there is a predetermined functionality and expected outcome when using additive manufacturing technology. There are also learning opportunities rooted in unforeseen equipment errors. The following chapter outlines alternate approaches for the use of 3D printing beyond mere representation and utilization in higher education design environments. Manufactured glitches enable students to analyze the predetermined functionality of the tools they engage with, and enter into a dialogue with technology as a medium for exploration and authorial exchange. To explore these concepts, a series of case studies that tested the parameters of glitches in both digital (three-dimensional modeling software) and physical mediums (rapid prototyping) was completed by a group of architecture and design students at a Midwestern University in the United States.

Abstract Additive manufacturing (AM), also known as 3D printing, has been used for rapid prototyping due to its ability to produce parts with complex geometries from computer-aided design files. Currently, polymers and metals are the most commonly used materials for AM. However, ceramic materials have unique mechanical properties such as strength, corrosion resistance, and temperature resistance. This paper provides a review of recent AM techniques for ceramics such as extrusion-based AM, the mechanical properties of additively manufactured ceramics, and the applications of ceramics in various industries, including aerospace, automotive, energy, electronics, and medical. A detailed overview of binder-jetting, laser-assisted processes, laminated object manufacturing (LOM), and material extrusion-based 3D printing is presented. Finally, the challenges and opportunities in AM of ceramics are identified.

A Practical Approach to Conveyancing takes a pragmatic, rather than academic, approach to conveyancing. It provides practical solutions to everyday problems encountered by conveyancing practitioners wishing to offer a cost-effective and efficient service. This volume offers a detailed and up-to-date exposition of the key principles and procedures underpinning the conveyancing process. The volume provides practical guidance on each stage of commercial and residential conveyances, with realistic sample documentation to aid in an approach of all aspects of a conveyancing transaction with confidence. This nineteenth edition has been fully updated with recent developments in the area, including coverage of the Land Transaction Tax, developments affecting ‘Help to buy’ shared ownership schemes, the facilitation of e-conveyancing as part of the 2003 Land Registration Rules, and proposed changes to the Land Registration Act 2002 currently under review by the Law Commission.

AbstractThe paper presents an ongoing project focusing on the application of additive manufacturing technologies for the design of staircases. Additive digital fabrication allows architects to reinvestigate materials, processes, and creates new design opportunities to explore novel aesthetical and functional expression in architecture, enabling a reinterpretation of the typology of the staircase, using thermoplastic materials. This paper reviews the opportunities and challenges of using 3D printing for fabricating custom stairs with complex geometries in two studied configurations.
