Before we go talking about titanium 3D printer, let’s just get to know the miracle metal a little closer. Titanium is a combination of strength and delicacy.

Titanium can bond with other elements by sharing its electron, and with some ions, it can even get charged electrically. Titanium can be found in all those applications where a considerable amount of force is required.

Do you know that Titanium is the hardest known metal on the earth? Not just that, it is also the best when considering the ratio of strength to weight.

All these qualities make the metal best for a variety of applications and within different niches. From automobile to entertainment to aerospace, every industry enjoys playing around with this metal.

The best part is that the metal isn’t as susceptible to corrosion that most of the metals are. Plus, it features a high melting temperature, even more than most of the metals we usually 3D print with.

All these reasons are sure enough to make titanium unique and well accountable when lightweight material resilience is what you need.

It is the best choice for all sophisticated applications. Let’s not wander too far. The example is very close by. Titanium is the best suit for biomedical implants.

How to Work with Titanium 3D Printing?

Titanium, as we know, owns the highest strength to its collar. Hence, it does require more consideration alongside with specialized preparation than any other metal alloy.

This is due to its unique physical properties that come along with the metal. You cannot use titanium with thermoplastic combination and use it as a filament spool for creating models at home. On the contrary, you will require lasers to tame the metal as you want.

And, not just any laser for that matter. You would require a high power laser to wrangle the metal in your designs. You must look for a Direct Metal Laser Sintering (DMLS) 3D printer.

When working with DMLS 3D printers, you do not have to worry about the design part. This is because most of the 3D Designing applications are compatible with a titanium 3D printer.

In fact, you can choose the one that is easier for you to handle or the one you are used to working with.

Above all, these 3D printers work with the same extension of files as the usual FDM 3D Printers. So, you do not have to think much about the output of the design files as well.

What is Different Then?

The game changes when you start building the 3D model out of the DMLS machine. In other words, the 3D printing process is completely different from the usual desktop printers.

It does the same job of creating the 3D models from the 3D files, but the process differs. And, it starts right from the time you plan to feed the 3D file to the titanium 3D printer.

Instead of connecting your 3D printer to the computer, you need to upload the 3D design directly to the titanium 3D printer.

Once you have the design inside the memory of the 3D printer, it’s time for the optic lasers to act. These sinters the titanium powder together to create the end product.

This laser directs to the special chamber, a part of the DMLS machine. There is a platform inside the chamber responsible for dispensing the material into layers.

The job of the laser is to melt the titanium from powder form to the liquid substitute. The liquid takes shape with the help of the blade.

Do not worry. It may sound complicated. However, the best part is that the machine would take care of the entire process that happens inside the titanium 3D printer. After you have transferred the 3D file to the machine, your task ends and the machine starts working.

Electronic Beam Melting (EBM) 3D Printing

Electronic Beam Melting (EBM) process

EBM is another 3D printing process that has been gaining a lot of attention from experts in 3D printing. Only by looking at the names of both these technologies you can find out the major difference between the two. Yes, it is the power source.

One uses lasers and the other makes use of an electron beam. Both these 3D printing process can work with titanium otherwise.

EBM produces higher energy output from DMLS. And, there are various other advantages too. You can expect an EBM machine to produce fewer internal defects with way better fatigue properties that that of DMLS machines.

These also result in minimal to no waste material. Plus, all the excess titanium powder is recyclable.

On the contrary, DMLS can help achieve finer layer thickness. It can produce a minimum of 20–40 μm. Whereas, through the EBM titanium 3D printer, users can get to 50–70 μm layer thickness.

Hence, DMLS can produce a better and smoother surface finish. And, this is the major reason why DMLS is still chosen over EBM in most of the cases.

There is one more approach for getting a clean 3D model with a titanium 3D printer. An approach introduced by Norsk Titanium. And, the process is known as Rapid Plasma Deposition (RPD).

So, what happens in RPD? It starts with melting a titanium wire to build layers of 3 to 4 mm in height and 8 to 12 mm in width. The entire process takes place inside a chamber which is covered with an atmosphere of inert argon gas.

The RPD produces comparatively rough surfaces when compared to DMLS or EBM. But it could work faster, close to 50 to 100 times in comparison to the powder-based 3D printing. As per the creators, the production process when monitored 600 times per second, can produce high standards of consistency.

And, the machine can build larger volume parts. Making itself one of the major entries in the world of 3D printing. However, the journey is still long.

To replace DMLS with any other technology won’t be that easier. To date, the best titanium 3D printer is the one working on the DMLS 3D printing process.
