What is Additive Manufacturing?

Additive manufacturing refers to a process by which digital 3D design data is used to build up a component in layers by depositing material. The term "3D Printing" is increasingly used as a synonym for Additive Manufacturing. However, the later is more accurate in that it describes a professional production technique which is clearly distinguished from conventional methods of material removal.

Additive vs Subtractive Manufacturing

  • In subtractive manufacturing we start with stock and remove material to get the net shape (traditional machining).
  • In additive manufacturing we start with nothing and add material to get the net shape.

In additive manufacturing, 3D objects are built by adding material in layer upon layer fashion. Materials ranging from plastics, thermoplastics, ceramics, biochemicals, metals, and concrete can be used for production in this sector. Even work is under process to develop human tissues using additive manufacturing techniques.

Following processes are involved in any AM technology:
  1. A CAD sketch is produced using a computer 3D modeling software
  2. The AM equipment is used to read this data from CAD file
  3. The AM equipment layd down successive layers of material which is to be used for fabrication of the product (this may include liquid, powder, sheet material or others).
3D printing, rapid prototyping, layered manufacturing, direct digital manufacturing and additive fabrication are all subsets of additive manufacturing.

Additive manufacturing technology is being actively used in the industry ranging from aerospace, automotive, healthcare and product development.

Categories of Additive Manufacturing

Binder Jetting: Liquid bonding agent selectively deposited to join powder
Material Jetting: Droplets of build material selectively deposited
Powder Bed Fusion: Thermal energy selectively fuses regions of powder bed
Directed Energy Deposition: Focused thermal energy melts materials as deposited
Sheet Lamination: Sheets of material bonded together
Vat Photo-polymerization: Liquid photo-polymer selectively cured by light activation
Material Extrusion: Material selectively dispensed through nozzle or orifice

The eight steps in Additive Manufacturing (process chain):

  1. Conceptualization and CAD
  2. Conversion to STL
  3. Transfer and manipulation of STL file on AM machine
  4. Machine setup
  5. Build
  6. Part removal and cleanup
  7. Post processing of part
  8. Application

10 Reasons to fall in love with mechanical engineers

10 reasons to fall in love with mechanical engineers – do you know why smart girls prefer dating a mechanical engineer? Mechanical engineers are some of the best people to date with. A good sense of logic, better salary, better communication, extra technical knowledge about almost everything makes a mechanical engineer a perfect guy to date. If you are looking forward to fall in love with a mechanical engineer as a boyfriend, husband or even father; here are the top reasons to justify your selection:

Read more here: Are engineers favorite among girls? In this survey more than 90% women said that they love to date engineers.

Subjects offered in mechanical engineering

Which subjects and courses are taught to undergraduate mechanical engineering students? As a pre-requisite, mechanical engineering students are required to study basic physics and mathematics courses at school level. During four year undergraduate study program, mechanical engineering students are required to study various subjects of sciences, linguistics, humanities and management. Fundamental subjects of mechanical engineering can be classified into following categories:
  1. Basic Engineering Courses (Core Subjects/ Optional Subjects)
  2. Design and Manufacturing
  3. Humanities/ Linguistics
  4. Management

Job Description of a Mechanical Engineer

What is job description of a mechanical engineer? What are job responsibilities, day to day tasks, duties and responsibilities of a mechanical engineer? A job description (JD) is a formal document containing brief information about mechanical engineer’s responsibilities.

Job description of mechanical engineers vary from industry to industry. For example, JD of a mechanical engineer working in automobile sector will be completely different from an engineer working in energy sector. In this era of automation, mechanical engineers play a pivotal role in growth of a company specially related to manufacturing. Typical job description of a mechanical engineer includes:
  • Design and manufacturing of new products.
  • Supervision of team of technicians.
  • Adherence to mechanical engineering standards, health and safety standards etc. Compliance of government regulations.
  • Writing training manuals, technical reports, handbooks and bulletins for products or engineering operations to help other team members understand the basics.
  • Preparation of feasibility reports for new projects and products based on historical data etc.
  • Assessing project requirements or operational requirements for setting up new projects or expansion of current operations.
  • Measuring performance of mechanical components, processes and products. Keeping log of all observations and necessary maintenance requirements.

I hope this job description of mechanical engineers gives you an idea about responsibilities, day to day tasks and duties of mechanical engineer. Learn more about basic concepts of mechanical engineering before you start applying for mechanical engineering degree.

Types of Jobs for Mechanical Engineers

What type of jobs are offered to mechanical engineers and what are career options for them? – One of the most commonly asked question from prospective mechanical engineering students. I have seen students worrying about career choices after graduation in mechanical engineering. Unfortunately, education system in most of the countries is run so badly that students are not given any guideline for selection of subjects and career field at school or college level. Almost all parents want their children to be doctors or engineers without knowing that what will be career prospects after getting into a particular field of engineering

Let’s talk about types of jobs for mechanical engineers. Mechanical engineering is as vast a field of engineering as this universe itself. When students ask me “what types of jobs mechanical engineers do after graduation?”. I usually reply with a counter question that “what type of job they cannot do?”. I have seen mechanical engineers working in all departments including security agencies, forensic departments, irrigation departments, energy departments, manufacturing sector, telecom sector, automobile sector, livestock, medical, pharmaceutical, industrial, space research, nuclear programs, waste management, legal, railways, transportation sector, chemical sector and even management sector. There is no field where mechanical engineers have not outshined through their performance, extra ordinary arithmetic and logical skills, and management practices.

Now the question arises, how a mechanical engineer is beneficial to forensic/ security agencies? I have a friend working in forensic agencies as a forensic engineer with basic degree in mechanical engineering. Mechanical engineering is 50% physics. At forensic departments, they need mechanical engineers to investigate cases and to identify damages done to vehicles, injuries caused by arms and tools keeping in mind basic action and reaction rules of physics. In security agencies, they need mechanical engineers to investigate industrial matters, to operate and maintain fleets of modern security vehicles, to develop new security tools and firearms, to develop modern micro level robots to investigate crime scenes and to get secret reports from areas occupied by militant forces.

Law firms require services of mechanical engineers to investigate all cases related to engineering sector. They hire freelance mechanical engineers for this purpose. Mechanical engineers are hired as consultants to work with legal and law firms. A law graduate cannot understand the complexities of an engineering case without help from a mechanical engineer. After discussing all these odd jobs for mechanical engineers, do I need to say more about types of jobs for mechanical engineers?

In short, there is no department where mechanical engineers cannot serve. Even I know few mechanical engineers working in spy agencies. Really? Do you believe this? Yes they do need mechanical engineers to keep an eye on what is happening in leading engineering sectors of other countries. Once you have decided to opt for mechanical engineering, they will teach you all the general courses of mechanical engineering without being specific to any field. Specializations are done only after graduation in Bachelors of mechanical engineering.

If you have any other question in mind, don’t hesitate to contact me.

World’s Largest Giant Trailer

Only Mechanical Engineers dare to make and lift heavy weights using World’s Largest Giant Trailer. Untiring efforts of engineers at Mammoet have made it possible to convert this dream of a giant trailer into reality.

Mammoet is world’s largest service provider with specialization in lifting and transporting heavy weights. Basically the idea is to develop a heavy transport solution called Trailer Power Assist (TPA). These trailers will be powered hydraulically thus lifting large and heavy equipment will not require combining several trucks.

Traditionally, you might have seen that (multiple trailers) four or five trailers are used to transport heavy cargo. Two or four trucks are used at front to steer the movement and two or four trucks are used at back for support to the cargo/ heavy equipment. The trucks are mechanical connected with limited maneuverability.

The new TPA-system has been initiated by Mammoet and developed in cooperation with SCHEUERLE, the leading manufacturer of heavy transport vehicles. TPA is based on the SCHEUERLE K25 trailer, which is fitted with a Power Pack Unit (PPU) that hydraulically powers 4 of the 6 axle lines. The PPU is mounted at one or either end of the trailer, depending on the configuration – or can be placed on the prime mover to replace the counterweight for traction. Each PPU is powered by a MTU V12 diesel engine, compliant with all emission requirements, that generates 1,000 horsepower and a traction power of over 40 tons. The TPA system is specified for all weather extremes. 

One TPA is equivalent to two trucks. Using this technology, only one truck will be required at the front to pull and steer the equipment. This means that only one experienced driver/ operator will be incharge here thus it will reduce any damages caused by communication gaps between several drivers of other trucks combined to move same cargo. 

TPA does not only provide more lifting capacity, but it also enhances speed of the vehicle. SCHEUERLE (Truck Manufacturing Company) is currently building two prototypes of TPA in a joint venture (JV) with Mammoet. In 2016, these two prototypes will be field-tested by Mammoet.

World’s Largest Waste to Energy Plant

World’s Largest Waste to Energy Plant will be built in Shenzhen, China. Design for waste to energy plant has been approved and two Danish architectural firms have won the competition to construct this modern facility for WTE plant. This will be a mega structure which will be used to generate energy/ electricity from waste treatment.

Total current population of Shenzhen city is estimated to be 20 Million. This proposed plant will have the capacity to incinerate one third of the total waste produced per day in the city. 5,000 tons of municipal waste will be burnt in this incineration plant on daily basis. Very first target of the construction company for this project is to build a safe and secure modern infrastructure and technical facility to deal with daily waste collected from the city. 

The building will not only produce energy from waste, but energy required for running the incinerators will also be generated from photovoltaic cells/ solar panels installed at circular roof of the building. For better aesthetics, landscape will be developed around the plant. This building will be constructed on modern techniques so that the plant offers best quality/ health standards for employees working there.

It is expected that the waste to energy plant will be completed till 2020 and it will be operational during same year. The plant does not only aim at producing energy from waste but engineers are of the view that an elevated walkway will be built inside building for education purpose of the visitors.
This is the real innovation that we always talk about. Rapid increase in population all over the world requires us to take such initiatives at city and country levels for treatment of waste for a useful purpose. Just like China, it is time for leaders and investors from other countries to start such projects of waste to energy because this project serves dual purpose:
  1. It acts as a waste treatment plant
  2. Energy is generated during treatment
I would like to recommend mechanical engineering students to take this project as a final year project idea at a small scale in their college/ university. Students can build smaller models of controlled incineration for generating energy/ hot water/ steam from water using incineration of waste.

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.”

Engineers Developing Drones to Hunt Drones

Engineers are developing drones that will be capable of catching other drones. Drones have proved to be very useful tool in this modern era. Their useful impact in the field of security, surveillance, media coverage, war zones, fire zones and weather conditions has brought a revolution in the way how things work. Everyday engineers are working on new ideas to use drones for constructive purpose instead of destruction and war. Rising interest in drones is bringing new ideas to reality.
No denying to the awesomeness of drone technology but what happens when drones are in wrong hands? Engineers are now working on this idea to design and manufacture a drone for security agencies of the world which will be designed to forcefully take off any flying machines that pose a threat to high security buildings like military bases, airports, government buildings or sporting events.
Net being used to catch drones.
The system installed inside this anti drone device will use modern techniques to reverse engineer the system of a drone under observation. It will take just few minutes to take full control of the drone. There will be another function if the drone could not hack into system of another drone. This anti drone device will shoot a net on other drone to catch it and fly it to a safe place.
UAVs are remote-controlled, pilot-less aircraft. They are designed to look like jets, airplanes and missiles or spiders with several helicopter-like rotor blades. Drones can be small enough to fit in the palm of your hand or as long as a 43-foot yacht. The machines can cost from as little as $30 for toys to as much as hundreds of thousands for professional-grade versions.
Use of private drones is a big threat to security agencies all over the world. Although it is identifiable, but sometimes it is not easy to find who is flying a drone in a crowd. It can be used for spying by any terrorist organization. Government security agencies are working on devising systems to control such unmanned devices. So far only way to stop or catch a drone is to identify the man who is flying it. This is not safe at all.
I spoke to a law enforcement agency’s representative in California this week and she informed that Government is planning to construct specialized control rooms in all major cities which will act as anti drone control rooms. Any drones or unmanned flying machines that will pose security threats will be controlled through this high tech infrastructure and brought to the security agency for further investigation. Licenses will also be issued for registration of flying machines.
