Latest Technology in 3D Printing

Every engineer is passionate to learn about latest technology in 3D printing. There are many engineers and scientists out there who are working on new ideas for improved results from 3D printing in all sectors of life. Fast developments and innovations have been observed in 3D printing technology over past few years. With introduction of modern materials in the field of 3D printing, it has become even more interesting for us all. In short, 3D printing has revolutionized the world of design, medicine, construction, robotics and manufacturing.

In this article, I would like to share with you few latest developments and technology in 3D printing sector:

Speed Printing: Previously the technology used in 3D printing was a layer-by-layer strategy (hence the word “additive.”). This was very time consuming and it had some serious disadvantages like waste of time and material, reduction in objects’ ultimate strength and so on. But those days of layer by layer manufacturing are now gone. Engineers have now introduced “Continuous Liquid Interface Production” in 3D printing. This production strategy uses molten metal to build products from 3D printing. This technology is 25 to 100 times faster than normal layer-by-layer printers.

The Printing Welder: The size of most 3D manufactured objects is controlled by the size of the 3D printer using which those objects were printed. Engineers have now invented their own method. “The innovation is a robotic arm with a print head that extrudes metal strong enough to support structure”. This innovation in 3D printers has enabled engineers to develop large size products like furniture and even bridges using 3D printers.

Phone Printer: As the name suggests, Jeng-Ywan Jeng, a professor of mechanical engineering and the dean of the engineering department at the National Taiwan University of Science and Technology is now working on this idea to use mobile phones as 3D printers. The idea is to scan an image/ drawing in mobile and then tiny printer installed with mobile device will use light from cell phone to print 3D models in no time.

3D Printing in Space Technology: Now 3D printers have enabled space agencies to build, test and rebuild space rockets and other products at space stations.

Biomedicine: It is believed that 3D printing will alter the entire face of biomedicine and human parts manufacturing. Even 3D printers have been used to help paralyzed people walk. Is there anything more awesome than this?

Going Cheap: It is believed that mobiles will be used for 3D printing just as they are being used for texting. At the same speed as well!

3D printing is the latest technique in engineering so I recommend all mechanical engineers to work on such ideas and take up project ideas related to 3D printing in their final year projects. Even a little contribution will lead to huge benefits in future because it is said “Be ashamed to die until you have won some victory for humanity.”

Are Engineers Favourite Among Girls?

What do girls think about men who are engineers and what type of engineers are most favourite among girls? A survey was conducted by a team of aboutmech with members chosen from different countries. Each team member carried out a neutral survey in his/ her country to evaluate what females think about most of the engineers from different engineering branches. An overview of different questions asked in survey is given below: Question: Which male engineers do you find more attractive as a husband? Almost 50% women voted for mechanical engineers to be the most attractive husbands among other engineers. So mechanical engineers are most favourite among girls as a husband. They find them more trustworthy, intelligent, and creative. A married women from California said, “If your husband is a mechanical engineer, he will help you in everyday tasks. Because mechanical engineers are good team players and they have creative ideas about everything.” Which male engineers do you find more

Best CV Format for Mechanical Engineers

Fifty percent engineers fail to grab a dream job because of basic faults in their CVs/ Resume. This article tells you about best CV format for mechanical engineers and how you are supposed to design your CV when applying for jobs. You CV is your first impression on future employer. He/ she does not know you. Your CV is the only representation of your personality. He/ she may select or reject you after first glance on your resume.  I have experienced shortlisting and interviewing candidates for different jobs. I was astonished to learn that most of the candidates simply copy paste each others CVs without any changes at all. These types of CVs are rejected immediately. I am not trying to tell you that you should avoid copying, rather i ma telling you to refrain from giving your CV to your friends. An ideal CV consists of following portions: Name/ Address of the applicant Objective Education Record Employment History Professional Skills Awards & Achievements Co-Cu

Engineering Mechanics - Introduction

The Engineering Mechanics is that branch of Engineering-science which deals with the principles of mechanics along with their applications to engineering problems. It is sub-divided into the following two main groups: (a) Statics, and (b) Dynamics The Statics is that branch of Engineering Mechanics which deals with the forces and their effects, while acting upon the bodies at rest. The Dynamics is that branch of Engineering Mechanics which deals with the forces and their effects, while acting upon the bodies in motion. It is further sub-divided into the following two branches: (i) Kinetics, and (ii) Kinematics The Kinetics is that branch of Dynamics, which deals with the bodies in motion due to the application of forces. The Kinematics is that branch of Dynamics which deals with the bodies in motion without taking into account the forces which are responsible for the motion.
