Buying a commercial metal 3D printer engages a lot of hard work and effort. These machines are expensive and once you spend money on the option you don’t like, you are pretty much stuck with it.

So, why to make things difficult for you? If you really wish to enjoy the perks of owning a 3D printer, you must do the groundwork beforehand.

As you must be knowing that metal 3D printing has become very popular among users. This is because of the many advantages it has over traditional manufacturing.

The parts printed are way better than the ones produced by conventional methods. These parts not only exhibit amazing qualities but also save a lot of materials which is wasted and cut off during using the old methods.

Do you know that almost 90 percent of the material is wasted in the process which does not employ 3D printing? It does end up wasting a lot of energy and resources.

Moreover, the printed parts are lighter. Because of which 3D printing applications has been welcomed by aeronautics and automobile industries. Jewelers are also finding the alternative very alluring.

Apart from printing prototypes, these machines have evolved to produce end products. One can depend on this powerful technology for realizing complex geometries that may not be possible using any other method.

List of Metal 3D Printing Processes

There are few 3D printing processes that use metals as material for creating parts from it. As time is passing, new technologies are surfacing around the basic ones. So, let us talk about the most popular ones.

Powder Bed Fusion Process

Powder Bed Fusion

This 3D printing process is used mostly by industries and large companies. In this process, the powdered metal is fused using an energy source.

This could be a laser or any other beam of energy powerful enough to fuse atomized particles together.

At a time, one layer is fused and the next layer is later deposited on the prior one. The process goes on until the entire object is created.

There are many different brands that are manufacturing machines based on the powder bed fusion process. And, already, the users from around the world are using these machines for various applications.

Binder Jetting Process

BJ (Binder Jetting)

Binder jetting also used the powder bed for creating parts with metals. In this process, the metal particle layers are glued together. These are then sintered in a high-temperature kiln. This is very similar to the process involved with ceramics. This process is very expensive too.

However, companies are using another approach to manufacture affordable metal 3D printers based on binder jetting. This is done by mixing the metal powder together with the metal paste.

This mixture is then extruded using a pneumatic extrusion 3D printer to create the desired 3D object. Later, the 3D part is sintered in a kiln to complete the process.

Directed Energy Deposition Process

Directed energy deposition

This process is very similar to the FDM process that we use for filaments. However, it may sound impossible to apply such a process for metals, industrial metal manufacturers are doing it very well. To accomplish this, experts utilize two different methods.

Directed energy deposition (DED) is one of the methods. It is also known as laser metal deposition (LMD). In this method, a laser beam is used to fuse metal powder. This is then deposited after being released slowly by an industrial robotic arm to form the layers.

Another way is to use the Electron Beam Additive Manufacturing (EBAM) process. This is similar to the soldering process. In this method, companies use a powerful electron beam to melt fuse a 3 mm thick titanium wire.

The melted metal is then used to give shape to very large metal structures. However, this process is not very common and usually utilized by Defence departments.

Titanium

Titanium - 3d printing material

Titanium is a very common metal in 3D printing. It is used in the form of Ti64 and TiAl4V. The metal is very versatile and can produce parts that are lighter yet stronger.

It can produce parts with a highly attractive finish. The metal is used widely for applications into the medical, aerospace and automobile industries.

In the medical industry, it is used for printing personalized prosthetics while in automotive or aerospace, titanium can be used for a number of applications.

From prototypes to part manufacturing is possible by using this metal. The best part is that the metal can be crafted using powder bed jetting as well as binder jetting processes.

However, users must be cautious when working with titanium. The metal is very reactive. This is the reason why it is used as a vacuum or when surrounded by the argon gas. Not a metal to be used inside the house. So, careful when choosing the metal for your business.

Precious Metals – Gold, Silver, and Platinum

Precious Metals - 3d printing material

Using precious metals for 3D printing is very challenging. Working with gold, silver, and platinum isn’t easy and these are mostly used with powder bed fusion processes.

The fact that these are expensive choices, one must ensure to manage the precious powders properly while keeping the aesthetic properties of the materials intact. These metals are used for applications within niches such as medical, electronics, jewelry, etc.

3D Printing Service Centre or Metal 3D Printer?

Before you plan to opt for buying the best metal 3D printer, you must check your options. If you are not printing regularly and in a huge amount, it would be completely pointless to own a 3D printer that prints with metals.

These printers are very expensive. You can expect them to fall within the range of $100.000 and $500.000 and even more. Moreover, maintaining these printers isn’t a piece of cake. You will need someone to operate and maintain the machine from time to time.

If you are planning to invest that much for 3D printing two or three parts a day or a few in a week, you would be playing with your savings. Or, the loan you are going to borrow would only seem a burden for you.

Do not be disheartened yet. You do have a choice here. You can still 3D print with metals. You can opt for 3D printing service centers that offer a huge advantage to users with personalized design requirements.

Here is a list of a few of those centers.

Shapeways: The company produces parts for different applications. Either you are looking for a functional prototype or an end product printed in metal, this would be a great choice.

I.Materialise: This company mostly works with large industries who need prototypes and printed products. However, the company has an online website that serves end users through printing the designs they upload on the website.

There are other companies too. Such as 3D Hubs, Sculpteo, and many others. You can choose any of these if you think spending on a 3D printer would be too expensive and infeasible.
