What is Metal 3D Printing
This additive manufacturing printing process covers the basic principles of SLM (Selective Laser Melting) and DMLS (Direct Metal Laser Sintering). Both processes use metals in granular form.
The only difference between the two comes down to the fundamentals of the particle bonding process.
SLM printing process uses metal powders with a single melting temperature and fully melts the particle while
Meanwhile, in DMLS or direct metal laser sintering, the powder is composed of materials with variable melting points that fuse on a molecular level at elevated temperatures.
Both SML and DMLS are used in industrial applications to create end-user engineering products. In some cases, they are collectively referred to as metal 3D printing.
Metal Additive Manufacturing is a printing process also known as metal 3D printing. This technology offers unrivaled design freedom with the ability to manufacture parts from a wide range of materials.
A number of components that were impossible to create a few years ago can be made to high standards using 3D printing metal powder.
Additive manufacturing or 3D printing allows you to create a three-dimensional part layer by layer from a polymer or metal-based material.
Traditionally, metal and plastic objects can be a wasteful process. For instance, when aircraft manufacture metal parts, the majority of the material up to 90% is cut away.
Unfortunately, metal 3D printers are very expensive. But this offers a lot of benefits from the traditional metal manufacturing processes.
How Does Metal 3D Printing Process Work?
Metal Additive Manufacturing works in the following process.
The build plate chamber is filled with inert gas to minimize the oxidation of the metal powder. It is then heated to the optimal build temperature.
A thin layer of metal powder is spread over the build plate platform and a high power laser scans the cross-section of the component, melting (for fusing) the metal particles together and creating the next layer. The entire area of the model is scanned so the part is built fully solid.
When the scanning process is complete, the build platform moves downwards by one layer thickness and the recoater spreads another thin layer of metal powder. The process is repeated until the whole part is complete.
Following the removal of support structures to separate the parts from the building platform, you can mill, drill or polish. For instance, internal surfaces such as those in internal or tempering channels can be polished using abrasive flow machining.
Here are the other ways to improve the surface quality of your 3D printed metal during the additive manufacturing process.
Heat treatment. This is used to improve the mechanical and tactile properties of the surface.
Electropolishing. This electrochemical treatment significantly improves the surface finish of metal 3D printing. This is used to minimize microroughness and reduce the risk of dirt or product residues. This also improves the cleanability of the surfaces.
This is also used for deburring, brightening and passivating for surfaces exposed to abrasive media. This process doesn’t involve mechanical, thermal or chemical impact. This can also be used to treat small and mechanically fragile parts.

#1 HP Metal Jet Review
HP is popular in the printing world, but they take their game at a higher level when they joined the market for metal 3D printing by producing a first-rate metal 3D printer in the form of HP Metal Jet.
What I love most about this all-metal 3D printer is its usability. This 3D printer is designed to propel your business with its most advanced metal 3D printers for mass production. It can produce high volumes of parts and large parts at a lower cost.
It can also accelerate product development cycles with multiple iterations in just days. It produces parts faster, in fewer steps with no debinding required and eliminates tooling.
It’s huge, so you need to have enough space to store it.
This 3D metal printer delivers extreme performance, high quality and consistent reliability which is just worth it considering its hefty price.
Personally, I find this 3D printer expensive. This is priced at $399,000. So, basically this is not for home use but it’s great if you are in the industry and is planning to use this for business.
Considering the things that this can do and the quality that it was built, you will not regret choosing this. I highly recommend this especially for those in the 3D printing business.
#2 EOS M 100 Review
EOS 100 is from a German manufacturer and was designed for entry-level industrial metal 3D printing without you breaking the bank. This is only among the few metal 3D printers that you can purchase below $250,000.
This commercial metal 3D printer is another affordable machine. This is manufactured by a company based in Frankfurt, Germany. This machine was introduced in 2015. This works using the Direct Metal Laser Sintering (DMLS).
I’m impressed with its built and size. EOS M 100 has a small build size with a maximum of 100 × 100 × 95 mm only. However, it can build items with complex geometries out of several different metals including EOS CobaltChrome SP2, EOS Stainless Steel 316L, EOS Titanium Ti64.
Despite its small build volume, its performance is impressive. It can produce approximately 70 dental crown and bridges in three hours. Yes, EOS M 100 is that fast. This is designed to be cost-efficient for small quantities of production.
The system also works smartly with its build space, efficient recoating and exposure strategy that reduces the non-productive periods and contributes to the efficient production of smaller quantities, instead.
As for its design, it has a modular interior structure. You can quickly dismantle or set it up. The materials can also be replaced easily and maintenance is a breeze. You can perform it quickly.
For your safety, this is designed with a closed frame. However, it may take time until you’ll get comfortable using this. This doesn’t include automatic calibration, heated print bed, or an LCD screen. But it has 3D scanners and touchscreen for easier operation.
As for connectivity, this is only limited to Ethernet. Most machines allow you to print using UBS, SD card, Bluetooth or Wi-Fi. When it comes to this matter, EOS M 100 is a bit behind.
Despite the things it lacks, I still love this metal 3D printer, from its size, price, performance and quality of output. I am also satisfied with its price.
Desktop Metal 3D Printer
If you need a 3D metal printing machine that fits your workspace then desktop metal 3D printer is for you. In this section, we are about to give you the top metal 3D printers in this category.
#3 Markforged Metal X Review
Markforged experienced an unparalleled success after releasing its first marquee product, Markforged Mark One. The brand went on and venture in producing metal printing 3D printers in the form of Metal X.
The first thing I noticed in this brand is that it’s a lot cheaper than HP Jet Metal by about $300,000. So, if your budget is short and you can’t afford HP’s metal 3D printer then this is a more affordable option.
Although this is cheaper, you should not underestimate Markforged Metal X in terms of performance. This is equipped with a new innovative process to create parts made with the machine using its own technology Atomic Diffusion Additive Manufacturing (ADAM).
ADAM involves the process of using a bound metal powder rod embedded inside a plastic filament. Similar to other 3D printing processes, the part is built up layer by layer except with compensations made for shrinkage.
I’m personally impressed with ADAM technology because it allows for closed-cell structures. Prior to this, you need an escape hole for the unused powder but with Metal X, the powder just burns away. Thanks to this, you can create complex enclosed internal structures to create light parts without sacrificing its strength.
What I love about this is that it can process various metal powders including Stainless Steel 17-4 and 303, Aluminum (Beta) 6061 and 7075, Tool Steel (Beta) A-2 and D-2, IN Alloy (Inconel) 625 (Beta), and Titanium Ti-6Al-4V (Beta). It is also equipped with a versatile proprietary cloud-based software called Eiger.
Perhaps, if there’s something that this 3D printer lacks it is poor connectivity. It has no USB, Wi-Fi, Bluetooth, SD card or ethernet.
Despite this, Markforged Metal X remains a good machine if you want to start printing with metal powders like stainless steel.
#4 Desktop Metal Studio Review
Desktop Metal Studio 3D printer is the first office-friendly metal 3D printing solution. This will be a great addition to your devices in the office especially if you want to join metal 3D printing.
This metal 3D printing machine operates differently than the laser-based system that selectively melts metal powder. Instead, this extrudes bound metal rods similar to how FDM printer works which eliminates the safety requirements often associated with metal 3D printing.
Don’t worry about any risks because this is designed to be safe in the first place. It comes with a closed-cell infill for lightweight strength. Thanks to this, you can move this conveniently when needed.
One of the best things about this machine is its price because this is much cheaper than most brands. At $120,000 Desktop Metal Studio System offers metal additive manufacturing (AM) at a fracture of the size and cost of typical industrial metal 3D printers. If you will only get the metal 3D printer, then it will only cost you $60,000.
This machine uses Desktop Metal’s patented Bound Metal Deposition (BMD) method which is similar to Fused Filament Fabrication (FFF) technology. BMD takes rods made of powdered metals bound in a polymer binder then extrudes it layer by layer. To prevent metal supports from bonding to metal parts, MBD employs a second extruder to deposit ceramic interface media between the two.
The good thing is that getting it doesn’t cost as much as the expensive metal 3D printing machines. The three machines can also fit neatly alongside each other. However, you would need a bigger space for this.
Overall, I’m still pleased with Desktop Metal Studio 3D Printer. I love its size, the quality of prints and of course, the price. And I tell you even if you purchase the entire Studio system, it won’t cost you as much as HP Metal Jet, so yes it is affordable.
