Contour crafting is an additive construction technique that uses a computer-controlled gantry to build structures layer-by-layer with concrete, requiring less labor than traditional construction. It was developed by Dr. Behrokh Khoshnevis to enable rapid, low-cost construction of homes. The process involves using robotic extruders and trowels to deposit and smooth concrete in precise layers to construct walls, floors, and other building elements.
Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers.
AM is a rapidly growing field that is having an impact on multiple industries by simplifying the process to go from a 3D model to a finished product.
In contrast to conventional manufacturing processes, AM fabricates objects by adding materials as required which eliminates the necessity of subtracting materials (by means of machining, milling, carving, etc.) to obtain desired shapes.
AM can advantageously fabricate complex geometries with no part-specific tooling and much less waste material.
In the construction sector, architectural models have been created with AM methods for more than a decade.
Recent years have seen a vast increase in research on printing methods for building components.
AM allows building companies to produce geometrically complex structures, to vary materials within a component according to its functions, and to automate the construction process starting from a digital model.
The technology can bring significant benefits to the construction industry in terms of increased customization, reduced construction time, reduced manpower, and construction cost.
Integrating parametric design with robotic additive manufacturing for 3D clay...Antonio Arcadu
ABSTRACT This paper presents an ongoing work in relation to the development of a parametric design algorithm and an automated system for additive manufacturing that aims to be implemented in 3D clay printing tasks. The purpose of this experimental study is to establish a first insight and provide information as well as guidelines for a comprehensive and robust additive manufacturing methodology that can be implemented in the area of 3D clay printing, aiming to be widely available and open for use in the relevant construction industry. Specifically, this paper emphasizes on the installation of an industrial extruder for 3D clay printing mounted on a robot, on toolpath planning process using a parametric design environment and on robotic execution of selected case studies. Based on existing 3D printing technology principles and on available rapid prototyping mechanisms, this process suggests an algorithm for system’s control as well as for robotic toolpath development applied in additive manufacturing of small to medium objects. The algorithm is developed in a parametric associative environment allowing its flexible use and execution in a number of case studies, aiming to tentatively test the effectiveness of the suggested robotic additive manufacturing workflow and their future implementation in large scale examples.

3D printing is called as additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. It is working under the principle of Fused Deposition Modelling (FDM). The 3D printing concept of custom manufacturing is exciting to nearly everyone. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.3D Printers are the machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner. Here we are going to propose a model report on design and fabrication of a 3D printer.
Augmented Reality to Access Dam Cracks InformationIJERA Editor
Augmented reality technology is a tool with great potential for application in several areas, including
engineering. During the early phases of the enterprise life cycle, as design and construction, augmented reality
has been widely used. Concrete dams, during operation and maintenance phase, require regular inspections as
part of the necessary activities to keep their structural safety. Cracks are common pathology in these structures
that must be detected, mapped and measured as their evolution may evidence structure compromising, need for
maintenance or intervention. In this context this paper aims to present a prototype to access in situ the dam
cracks information through the use of augmented reality, thus giving a contribution to the effectiveness and
efficiency of inspections.
Development Prototype Design of Virtual Assembly Application-Based Leap MotionIJAEMSJORNAL
Innovation in design engineering practice is very important in the world of manufacturing in the increasingly competitive global market. Prototyping and evaluation measures are inseparable from the design process in the manufacture of a product. And made one of many physical prototypes require very expensive and time consuming, so the technology of Virtual Reality (VR) is needed, so the industry can quickly and precisely in the decision. VR technology combines a human being with a computer environment visually, touch and hearing, so that the user as if into the virtual world. The goal is that users with hand movements can interact with what is displayed on the computer screen or the user can interact with the environment is unreal to be added into the real world. VR is required for simulations that require a lot of interaction such as prototype assembly methods, or better known as the Virtual Assembly. Virtual Assembly concept which was developed as the ability to assemble a real representation of the physical model, the 3D models in CAD software by simulating the natural movement of the human hand. Leap Motion (accuracy of 0.01mm) was used to replace Microsoft's Kinect (accuracy of 1.5cm) and Motion Glove with flex sensors (accuracy of 1°) in several previous research. Leap mot ion controller is a device that captures every movement of the hand to then be processed and integrated with 3D models in CAD software. And simulation of assembly process virtually in CA D software with hand gestures detected by the leap mot ion, assembly parts can be driven either in translation or rotation, zooming and adding the assembly constraint. It also can perform mouse functions (such as left-click, middle-click, right-click and move the mouse cursor position) to a virtual assembly process simulation on CAD software.

Design and Modelling of a Leaf Spring using 3D Printing Technologyijtsrd
3D printing technology forms the basis of corporation's prototyping process. 3D printing technology creates 3D physical protypes by solidifying layers of deposited power by using a liquid binder. 3D printing is an versatile process accommodating geometry of varying complexity in hundreds of different applications, and supporting many types of materials. By eliminating production steps and using substantially less material, additive process could be able to reduce waste and save more than 50 of energy compared to today's subtractive manufacturing process and reduce material cost upto 90 . The use of additive manufacturing can potentially benefit a wide range of industries including defence, aerospace, automotive, biomedical, consumer products and metal manufacturing. A leaf spring is a simple form of spring, normally used for the suspension in wheeled cars. Leaf springs are long and narrow plates attached to the body of a trailer that rests above or under trailer's axle. For safe and cozy using, to prevent the street shocks from being transmitted to the car components and to guard the guard the occupants from the road shocks it's miles important to determine the maximum safe strain and deflection. The objective is to find the stresses and deformation in the leaf spring via making use of static load on it. One of a kind of special materials with mechanical properties are taken into consideration for the structural static evaluation. All leaf spring has linear characteristics there is a linear dependence between force and deflection this means that the 3D printed springs could be used as machine elements in different applications.

Whats more, this could change the development component. In simple future, numerous nations and organizations will utilize these 3D printing systems to build inventive structures. The reasons why we would love to utilize 3D printing is that it is particularly less expensive than the customary strategy. Not just the expense of development it likewise incorporates the expense of materials utilized, cost of works and so forth. At the point when contrasted with customary strategy it requires less exertion, time utilization is likewise less. The strategy will likewise cut expenses and natural harm by decreasing the measure of broken blocks that is utilized. The thought is that the base of the robot is fixed with the arm sufficiently long to achieve any piece of the structure being manufactured. Exact situating is accomplished by a fixed marker in an alternate position from the robot. The entire procedure is robotized. The developments will be in xyz arranges. Stepper engines are utilized for developments. Timing belts are utilized for straight movements. DC engines will be utilized for gripper system. The structure never should be contacted by human hands. Regardless of whether they are compact printers utilized nearby or are housed in a stockroom, 3D printers can possibly totally reform the constructed condition. With such huge numbers of potential advantages of Smart Construction, theres nothing unexpected that this technique is advancing through an assorted number of ventures and rapidly turning into a most loved device of dynamic advertisers.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
