3D Printing: Completely a Boon to Humans

What is Trending?

  1. On March 17, 2016 The Conversation author Sebastian Greenhough wrote the blog describing th progress of 3D Printing in printing Facial Human Cells.
  2. On August 29,2016 columnist Tess of 3ders told us about the successful implant of 3d printed Titanium Vertebrae Prosthetic by Chinese Doctors.
  3. On August 30, 2016 LIVESCIENCE columnist Richa Malhotra broke the news about Face Recreation of an Egyptian Mummy through 3D Printing.
  4. On August 31, 2016 columnist Nick of 3ders described about the Russian Cement Company 3D prints 6-meter-tall the Game of Thrones-style Tower.
  5. On 1 September, 2016 columnist Alec of 3ders shared the news about a New Zealand professor planning to 3D Print synthetic wood.

It seems that 3D Printing Technology had only been invented to be a much needed boon for Humans. It is great to think that 3D printing has a solution for almost all things. From printing text on papers it has grown to printing living human cells and bones, which indeed proves to a great blessing.

Reading the above trending updates, I am sure that you would be anxious to know about this technology and about what is the next update that you would get to know in this blog. I am here to share all the information on what future developments you can expect from the technologies. And not just that even a small gist about what the technology is and how it all started. So, this blog is also comprising of the same.

Let’s Know what it is

3D Printing is a process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material. It brings a digital object into its physical form by adding layer by layer of materials.

3D Printing — also known as additive manufacturing — has been quoted in the Financial Times and by other sources as potentially being larger than the Internet. It is deemed an additive process because the object is built up from scratch, as opposed to subtractive processes in which material is cut, drilled, milled, or machined off.

How to print a 3D model?

There are several different techniques to 3D Printing an object. 3D Printing brings two fundamental innovations: the manipulation of objects in their digital format and the manufacturing of new shapes by addition of material.

The digital format of the object can be created using a variety of 3D software programs like for industrial use we have 3D CAD software, 3D scanners for general consumers and some simple Softwares for general people use.

Every 3D print starts as a digital 3D design file – like a blueprint – for a physical object. Trying to print without a design file is like trying to print a document on a sheet of paper without a text file. This design file is sliced into thin layers which is then sent to the 3D printer.


From here on the printing process varies by technology, starting from desktop printers that melt a plastic material and lay it down onto a print platform to large industrial machines that use a laser to selectively melt metal powder at high temperatures. The printing can take hours to complete depending on the size, and the printed objects are often post-processed to reach the desired finish.

Available materials also vary by printer type, ranging from plastics to rubber, sandstone, metals and alloys – with more and more materials appearing on the market every year.

The different 3D Printing techniques and the sample objects printed by them are depicted in the below images:

Industrial Applications

  • Medical Sciences
  • Automobiles and Aircraft Manufacturers
  • Product Designers
  • Architects
  • Students
  • Engineers
  • Shoe Manufacturers
  • Design Entrepreneurs
  • Movie Prop Makers
  • Consumer Product Makers



  • Manufactures complex designs.
  • Customization available for each and every item.
  • No need for tools and molds, lower fixed costs.
  • Less time consuming and easy manufacturing compared to conventional methods.
  • Environment friendly technology and produces much lesser waste.


  • Higher cost of printers and materials eventually increasing the cost of large production runs
  • Limited choice of colors, materials and finishes
  • Low in strength and endurance compared to traditionally manufactured objects

My Prediction

The technology for 3-D printing has existed in some form since the 1980s. Expectations are running high that soon we would overcome above disadvantages. Technical improvements are being researched on to increase the strength and endurance of the materials. Addition of new materials to 3D Printing is growing the 3D printing palette. The increasing demand for it will eventually lower the cost of the raw materials and the printers.

There is more in the future as this field advances at a staggering rate and futurists are calling it the revolution of 3D printing like never before. I am predicting that in a decade or so you would be able to see some of the below changes:

  1. Human Robot

In reading it may appear crazy to you, but I have high expectations for that. We have already achieved some milestones in printing the bones and human cells. So, a Robot in a Human Body is not at all a crazy prediction. Companies could come up with the basic digital model developed in CAD software for the “Human Skeleton”. Model designing would even see to the criticalities of joint movements. Features of human body movement could also be considered in it.

So, one printer would print the human skeleton and the other would print the human skin, for which we already have the printers. And this would not even have the adaptability problem as there is no real human acquiring that skin.

Now the question is how is it going to work as a robot. Well, the answer is simple, the robot machinery that we fit in the metallic body could be fitted into this. Even Scientists are developing computers as small as a SIM which could be fitted in the brain of the robot and proper connections to body parts could be done through optical wires.

  1. 3D Printer Manufactured Homes or Buildings

After the success of Russian cement company in making the tower of Game of Thrones we could expect this as the next big achievement in the field of 3D Printing. Researches are working on strengthening the raw material and lowering the production costs. And soon we would be seeing the industry made homes in Dubai Rotating Towers. And after that 3D Printed Houses and buildings is not a far fetch dream.

  1. 3D Printer Consumable Fast Food Vending Machine

Yes, you read that right! Printer printing ready to eat fast food. Making such a printer would be a tough task or may be it could just be in papers. But I expect that it could be achieved. I am not saying that the vending machine would print all types of ready cuisines. But just some of them like cupcakes, nachos, chips, sandwiches, etc. Some of the stuffs like that.

We already have printers printing chocolates. So, expecting this printer is not that unimaginable. This Printer would have the saved 3D images and programs to print them. It could have different storage sections for all different stuffs. These storage sections would have the ready mixtures containing the spices and ingredients. And at the selection of the item and its amount it would ask you to enter the money and then it would print the eatable.

The above told future predictions are just some thoughts of my mind which I got reading about the advancements of 3D Printing. 3D printing is getting cheaper, faster and more accurate. Most reputable commentators on this technology sector agree that, as of today, we are only just beginning to see the true potential of 3D printing. It won’t be long before the technology expands from particular niches into the rest of the industrial sphere. From there the domestic world is just a short hop.
