There are a lot of different 3D printing technologies and 3D printing materials actually available on the market. Metal 3D printing is developing really fast, and new technologies, 3D printers and 3D printing materials are unveiled quite regularly. This metal manufacturing process is really promising, giving life to outstanding projects. But metal 3D printing includes different technologies, and it can be a little bit difficult to understand exactly what they are all about.
How does metal printing work? What are the applications of the metal 3D printing technology? You will learn everything on this page, and we will tell you all you need to know about the benefits of metal printing.
Keep in mind that thanks to our online 3D printing service, you will be able to choose among various metal materials for your projects!
There are several 3D printing technologies on the market to create metal parts using additive manufacturing. When starting a 3D printing project using metal materials, you will have to make your choice between all of these technologies and materials depending on the project that you are working on. Each metal 3D printing material has its own mechanical properties.
We can notice two big categories: Powder bed technologies and Laser Metal Deposition technologies. They are the most used and you can totally manufacture parts printed with these two different processes.
The powder bed technologies uses, as their name tell us, a powder bed: the powdered metal is fused to create the parts additively. Metal deposition technologies are adding layers of materials. But let’s see more in details how these techniques are working, and how you could make the most of them.
But first of all, we are going to explain to you the benefits of this technology, how it is actually used in various industries and why you should pay attention to this manufacturing technique and try it! This additive manufacturing technology is a great method to manufacture finished parts.
Metal 3D printing has all the traditional benefits of the additive manufacturing technology, allowing:
3D printing is a great way to elaborate complex designs. By using a 3D modeling software, you will be able to design any kind of projects. When designing your project for metal printing, you will have to pay attention to the design guidelines of the material you choose, in order to create a printable and viable part.
Additive manufacturing is the best solution if you need to manufacture custom-made objects. Indeed, this method will be quite cost-efficient for these projects, as you just have to modify your 3D design and print it using, for example, a 3D printing service such as Sculpteo.
Using a 3D modeling software offers many advantages. You have a total control on the object that will be manufactured. It is the perfect method to optimize directly the design of your project, by modifying the shape or adding structures such as lattices. 3D printing allows to optimize your part by reducing weight, or work on the resistance of the part.
Additive manufacturing is a really convenient and cost effective technique to manufacture short runs. Indeed, it can totally be a cost efficient method for your project, depending on the technology, on the 3D printing material Have you ever thought about applying these 3D printing benefits to your metal projects? You should certainly think about it.
Metal 3D printing is useful as it is allowing to create devices and parts that we couldn’t manufacture with a 3D printed plastic material. Parts manufactured with metal materials can be really resistant and can be used as finished parts in sectors such as automotive, aerospace or aeronautics :sectors requiring parts with specific mechanical properties.
This printing technique can be used to manufacture objects for various different projects. We are noticing that the use of metal 3D printing is actually growing year over year in sectors such as aeronautics and aerospace, which need to stay innovative. This manufacturing process allows to create high-performing mechanical parts, it is a perfect solution to work on metal engineering. 3D printed metal parts can totally be used for automotive or medical applications, it can be a great methods for you to create 3D printed tools.
But metal 3D printing is not only used for functional applications, it is also well-used for jewelry! Indeed, as we just saw, one of the most interesting benefits of 3D printing is mass-customization. This technology is actually allowing to create custom-made products really easily.
You want to make the most of this technology and get all these benefits for your business? Now let’s see the various metal technologies available on the market.
Selective Laser Melting is a 3D printing technology developed to print metal alloys. A laser beam comes sintering the material, layer by layer, according to the shape of your 3D model. Unlike technologies such as Direct Metal Laser Sintering, the powder is fully melt during the printing process, thanks to an inert gas such as argon or nitrogen. Selective Laser Melting (SLM) is a good printing technology for pure materials such as aluminum.
While printing with this 3D technology, you need to use supports in order to reinforce small angles and hangovers, and get a part perfectly 3D printed. These supports have to be manually removed after the cooling process of the parts. This technology has a longer cooling time than the Direct Metal Laser Sintering (DMLS) technology, as Selective Laser Melting (SLM) needs a higher temperature to fully melt the material.
This technique has many advantages. First, it is allowing to create really detailed parts, and it also enables to integrate multiple components. There is also this possibility to create thin-walled objects. Be careful, you always have to respect the design guidelines of the materials that you are using, if your walls are too thin, your file will be non-printable, or your part could break. This technology is great to manufacture resistant industrial metal parts, such as propellers or gears.
A few examples of 3D printers using the Selective Laser Melting technology:
Direct Metal Laser Sintering (DMLS) almost works like Selective Laser Melting (SLM). It sinters the metal powder according to the shape of your 3D model. The difference is that Direct Metal Laser Sintering (DMLS) doesn’t fully melt the powder like an SLM printer does. The consequence of that is that metal prints made with the DMLS 3D printing technology don’t need to reach a temperature as high and therefore the cooling time is shorter.
Benefits of DMLS and SLM technologies are quite similar: It is a great solution to print multiple components into only one object, to create
There are various metal 3D printers, in our 3D printing factory, we use these 3D machines for Direct Metal Laser Sintering:
In this metal 3D printing process, the metal powder is placed under a vacuum and fused thanks to the heating of one or several electron beams. This additive manufacturing technique is melting the metal powder layer by layer according to the shape of your 3D model. The reason why this process has to be done under a vacuum environment is to prevent oxidation of the material.
This process operates at
Materials available on the market with this technology: Titanium and Cobalt’s alloys.
Examples of 3D printers used for the Electron Beam Melting technology:
This metal 3D printing technology, working by addition of layer, a little bit like the Fused Deposition Modeling (FDM) process. Indeed, the feedstock is brought and fused at the same time through a nozzle. They are many different terms that are referring to this same technique, like Laser Cladding, Direct Metal Deposition or Laser Engineered Net Shaping.
The principle of the printing process is still the same. For this additive manufacturing technology, a powdered metal material is melted and then consolidated using a laser.
The process is including a deposition of the metal material, layer by layer. It has a great accuracy and a high resolution for micro-structures. The substrate can be positioned either in a stationary position (3−axis systems) or on a rotating stage (5+ axis systems) to increase the ability of the machine to process more complex geometries.
What we call Laser Cladding is more about adding layers of material on an existing object, but the process is still the same. It is a great solution to improve the corrosion resistance of metal parts. Indeed, used as
Materials such as steel and aluminum can be printed using this manufacturing technique.
Binder Jetting is an additive manufacturing technique that creates parts additively with a binding agent. The process uses a liquid binding agent deposited on the metal powder material thanks to an inkjet head. This metal 3D printing method uses a layer-by-layer technique and creates the shape of the object according to your CAD file.
After this printing process, a consolidation process is required to add the complete mechanical properties of the
As it can create complex shapes and geometries quite easily, Binder Jetting appears to be one of the best metal 3D printing processes to create jewelry.
The cost of
Binder Jetting materials that we are producing in our 3D printing factory are:
Lost-wax casting is an alternative to additive and subtractive manufacturing to create multiple models from a first master model that will be used as a reference. The master model is
