3D printing: technology, machines and their cost estimation

3D printing is a process of making 3D objects from a computer-aided design (CAD) model by adding layer by layer over each other in a defined pattern to build a definite structure. This technique of adding one layer of material after another is called additive manufacturing (AM).AM is responsible for the solidification of 3D objects. This process is highly intensive and effective for creating complex objects over a short period of time and especially when the bulk of that is not needed.

Working

Modeling  and slicing

The most basic but significant step is of creating or taking access to the 3D model with the help of a 3D scanner , haptic device or 3D scanner and CAD software.
After that, your next step would be to prepare the file for your 3D printer that’s also called as slicing from 3D model to 3D printer file. This slicing software divides the 3D model into numerous layers horizontally after that you are ready for the next step. For slicing, there are many software externally but most of the 3D printers have built-in slicers.

Printing process

Now it’s the turn to choose the material of which object will be printed. The material should be appropriate for your objects and satisfying your needs. There is a broad range of materials which we can be fed in our printer, out of which some are plastics, ceramics, resigns, sand, lunar dust and more
After selecting  the material you are now moved towards last step in which you  check orientation, size and final preview of our model and after that your printer starts printing.

Finishing

Now your object’s model is ready but not to deliver or use, before delivering it had to be sanded or painted for getting a final product.

The material you use for your project will determine the printing method.

Some methods are listed below

IF WE USE PLASTIC the methods are
  • FDM(fused deposition modeling) technology
  • SLS TECHNOLOGY


IF WE USSE WAX
  • Digital light processing (DLP)
  • Multijet printers

IF WE USE METALS
  • DLP
  • Electron beam melting (EBM)

IF WE USE MULTI COLOUR
  • Binder jetting
  • Triple jetting technology ( polyjet )


The automotive industry, aviation industry, health sector, artificial products, aerospace, bioprinting, complex models, small machinery parts, these all are some fields in which 3D printing is establishing its roots.

One could buy a 3D printer from any trustful e-commerce site. The product range starts from 150k and even quiet more.

Blockchain technology  Technology is rapidly developing, which might be a new or upgraded version of the old. All these effort putting their footsteps forward towards a user-friendly environment. The sack of the same blockchain was developed in 2008. Blockchain is an open-source ledger that has the ability to record transactions between two or more single party accounts effectively and with the highlighting feature of verifying the authenticity of every end-user details. Initially, it was designed to serve the users of cryptocurrency bitcoin but now days are used in other decentralized networks such as ethereum . Blockchain has brought a revolutionary change in the field of digital currency which has a strong foundation of each end secured transitory system. As the name suggests blockchain is basically a community or group of people connected over a network in which they practice their transactions. The word ‘ block ’ means the set of a database of ea

Artificial Intelligence: intelligent machines i.e. robots, driverless cars... The world with the growing pace of technology in on the peak. Modernization of society with brisk technological reforms and fundamentals had led the life to experience a greater exposure in delight.  Among much other intelligence, the field of artificial intelligence is progressing rapidly in every field and sphere of routine life. Artificial intelligence  is the field of computer science which inhibits the technological world to create an intelligent machine that work, react and could think like a human. It is up growing field of technology which could make the pure sensation virtual world.  This intelligence revolves around the use of an algorithm, which is a set of unambiguous instructions that a machine can understand. Many of us understand this term as machine intelligence or also robotics. Many algorithms are capable of various abilities like understanding human instructions, speech, em

Nanotechnology: explained, usage, define and projects based on it Nanotechnology is a part of science and technology that changes the molecules of objects on the atomic and molecular scale.  The size of a nanoparticle is equal to eight-hundredths of the root of human hair.  The molecules in these experiments are between 1 nanometer to 10 nanometers. This technology is capable of solving many crucial environmental problems like cleaning the environment, preserving the amount of energy, improving our health, etc. It is able to increase the manufacturing cost of many items at a low cost. In the coming days, due to this technology, the goods will come cheap, small and light. Talking about the importance of nanotechnology, in 1999, Nobel laureate Richard Smalley had said, " There will be significant changes due to nanology in areas such as microelectronics, medical imaging, computer science, polymer science." Here are some of the uses of nanotechnology according to

5G TECHNOLOGIES: explained and when to launch, speed and everything about it 5G, A fifth-generation technology   - is a software-defined network which means it could entirely replace the cable and would use cloud storage as the basic platform. This would make more personalized experiences using the technique “ network slicing ” which is a way of creating separate wireless on the cloud for different networks.it initiates the potential to transform the internet.   5G network runs on the super high frequency which is just a bit less than satellite broadcasting. The future of automation has a boosting charge with a 5G network which could increase the efficiency of artificial intelligence operated or automation technology operated devices. How it works? As all other cellular networks work, 5G will consist of cells that would be divided into sectors and will send data through radio waves Each cell in this is connected to the backbone of the network through

INTERNET OF THINGS Nowadays we are positively progressing in 21 st century, almost all well introduced with the internet. It’s a pace of time where we can’t think of daily life without the use of the internet. This could be easily understood when we study the extension of internet connectivity into our physical world i.e. remote-controlled devices, virtual things and applications with sensors commonly renowned as   INTERNET OF THINGS (IoT). IoT is a joint network of all connected devices. These devices gather and store valuable information over the giant common platform offered by the internet. The emission of all information from the physical device is done with the help of embedded sensors in almost all physical devices and gathers data over IoT. Internet of things categorize things into three wider categories: Things with the ability to receive and sending data Things with the ability to collect and send data Things with the ability to collect receive
