3D printers and it’s usage in many industries

It is a device which print 3D objects, as it’s name suggests. 3D printers have become a new ideal technology to manufacture something efficiently and without producing much wastage. It is used in variety of fields smaller or bigger. It has gained popularity in no time and it’s sale is increasing day by day. There are lots of 3D printers available in the shops around you as well as online. You can find best 3D printer in the shops near you as well as online. It is a complex machine to use and not handy for everyone. It operates through application which can be in your desktop or in your mobile. There are several steps which is involved if you want to make something through it.

It is now used in many industries due to its rapid production ability. It can boost up any manufacturing and also reduces labours and wastage which ultimately going to save your money. This is why it is so reliable for the manufacturers. It is used in almost every industry for the process of design and model making. Many manufacturers are using this technology to manufacture their model. While manufacturing their model it guarantee that it will have less error and will have sharp design as well.

Here are some common industries which are using 3D printing technology.


It can be said that it is the first industry which uses 3D printing technology first time and using it from a long time. Car manufacturers have been utilizing 3D printing for a long time. Automotive companies are printing spare parts, tools, jigs and fixtures but also end-use parts, and many more. 3D printing has enabled on-demand manufacturing which has lead to lower stock levels and has shortened design and production cycles. After this, car manufacturers does not have to made parts and make it in stocks rather after this 3D printing technology, they can make manufacture the parts on the spot after the demand. This saves their time and money and also they have got relief from the tension of stock.

Automotive enthusiasts all over the world are using 3D printed parts to restore old cars. One such example is when Australian engineers printed parts to bring a Delage Type-C back to life. In doing so, they had to print parts that were out of production for decades.


The aviation industry uses 3D printing in many ways. The following example marks a significant 3D printing manufacturing milestone: GE Aviation had 3D printed nearly 30,000 Cobalt-chrome fuel nozzles for its LEAP aircraft engines. They achieved that milestone in October 2018, and considering that they will produce 600 per week on forty 3D printers, it’s likely much higher than that now.

Almost twenty individual parts that previously had to be welded together were consolidated into one 3D printed component that weighs 25% less than the previous one and it is also five times stronger also. The LEAP engine is the best selling engine in the aviation sector due to its high level of efficiency and GE saves $3 million per aircraft by 3D printing the fuel nozzles, so this single 3D printed part generates hundreds of millions of dollars of financial benefit.

GE’s fuel nozzles also made their way into the Boeing 787 Dreamliner, but it’s not the one and only 3D printed part in the 787. It also has many 3D printed parts in it. The 33-centimeter-long structural fittings that hold the aft kitchen galley to the airframe are 3D printed by a company called Norsk Titanium. Norsk Titanium choses to specialize in titanium because it has a very high strength-to-weight ratio and is rather expensive, meaning the reduction in waste enabled by 3D printing has more significant financial impact than compared to any other cheaper metals where the costs of material waste are easier to absorb. Rather than sintering metal powder with a laser like most metal 3D printers do, the Norsk Merke 4 uses a plasma arc to melt a metal wire in a process called Rapid Plasma Deposition (a form of Directed Energy Deposition) that can deposit up to a 10kg of titanium metal per hour which is a huge amount.

A 2kg titanium part would generally require a 30kg block of titanium to machine it from, generating 28kg of waste, but 3D printing the same part requires only 6kg of titanium wire, which saves lot of metal or we can say lot of money. It has also reduces the waste production.

Boeing has been using 3D printed parts in their airplanes for a long time. Back in 2015 it was estimated that Boeing had more than 20,000 3D printed parts implemented in their airplanes.
