This document discusses 3D printable concrete, including its mixture design, simulation, and testing methods. It begins with an abstract that outlines the benefits of 3D concrete printing for construction projects but notes challenges around standardization and accessibility.
The document then reviews literature on 3D printable concrete mix design, concluding that current codes and standards do not apply and a trial-and-error approach is typically used. It introduces the concept of "manual extrusion" or handheld 3D printing to experimentally test concrete mixtures in a cost-effective way.
The methodology section describes developing a manual extruder, studying existing mixture data, optimizing aggregate packing using software, conducting extrusion and printing trials, and testing samples to improve the

Design and Development of Spur Gear by using Three Dimensional Printingijtsrd
Gears are power transmission devices in between input and output of machines, these power transmitting elements are very compact, and they transfer power with minimum loss. Due to the nature of their different speed ratios they are used for different applications like high speed marine engines, automobiles etc. Different materials are used for preparation or fabrication of gears like metals steel or brass , plastics nylon or polycarbonate . In this project spur gear is designed by CAD software and fabricated by using 3D printer, for 3D printing materials require like plastics or ceramics but for this project plastic material is used that is polylactic acid PLA . By using 3D printer spur gear is produced within a small period with better dimensional accuracy than conventional method like milling etc. P. Naresh | Aman Raj | J. Tarun | Ejazur Rahman | G.

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.

Abstract 3D Printing is a process of manufacturing the product on the layer by layer. And it is best processes for producing a finished objects. It was started in 1980‟s with the invention of stereo lithography. It has gone through various ups and downs throughout its development and rejection of new technologies. In this paper, we h3ave summarized the printing of hollow compounds with different shapes. Applications of 3D printed hollow compounds are turbine blades, gears, disc brakes etc. One of the major application of 3D printing is hollow turbine blade. A turbine blade is the individual components. These are used to up the turbine section of a gas turbine. The blades must designed to withstand the high pressure and high temperature comings from combustor. These 3D printed hollow compounds has same strength as solid compounds when compared. Major advantages of the Hollow shaped compounds are heat transfer, low material cost. The aim of the paper is to reduce the cost of material and easy manufacturing of hollow compounds compared to traditional process and taken hollow turbine blade as example. Keywords: hollow compounds, 3D printing, turbine blades, Additive manufacturing.

THE METHOD FOR OPTIMUM DESIGN OF RESIN INJECTION MOLDING PROCESS CONDITIONS U...meijjournal
In recent years, the demand for plastic products has increased, and along with the deepening of academics,
mass production, weight reduction, and high precision are progressing. In the fields of design development
and production technology, there are many issues related to quality assurance such as molding defects and
product strength. In particular, in the resin molding process, there is a high degree of freedom in product
shape and mold structure, and it is an important issue to create quality functions that apply analysis of
complex multidimensional information. In this study, the important factors of the resin molding process
related to the optimization of resin strength are extracted by applying the multivariate analysis method and
robust parameter design. As a result of verification of the proposed method, it is clarified that uniformization
of the resin filling density in the mold is extremely important for stabilizing the resin strength.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

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!
