10 Best Metal 3D Printers

Metal 3D printing has become a hot topic recently mostly due to the fact that the current 3D parts that are being printed are really good quality. So good in fact, some of it is actually better than what is made by normal methods.

Traditional methods tend to be wasteful when it comes to making metal and plastic parts. Often, when metal parts are made, almost 90 percent of the metal material is cut away creating a lot of waste and using a lot of energy. By using a 3D printer to create these same metal parts, manufacturers can use less energy and minimize waste.

Plus, the metal pieces that are printed can weigh up to 60 percent less than those pieces made with traditional manufacturing. Industries such as airlines can save a lot of money in fuel with this type of weight reduction. This has been an exciting new technology to keep an eye on as there can be so much development in a short period of time, things can progress almost within the blink of an eye.

Attempts to print with metal can actually be traced back to the 1880s by welders using carbon electrode arcs to fuse pieces of metal together. It really wasn’t until the development of the laser that 3D printing was brought to the general public and the eventual introduction by NASA of the technique called selective metal melting (SLM) Engineers at NASA has made it successful in producing parts with complex geometry and dimensional accuracy that is beyond what was thought possible with regular fabrication methods.

The fastest method of 3D printing has been discovered through depositing a powder metal matrix that has binders and, after each layer is deposited, the binder is melted and held together temporarily until a final baking in an oven. This process has been streamlined by Shapeways to give the public the fastest process possible from a variety of metal materials.

Industrial Metal 3D Printing

Buying a metal 3D printer for your business is a big and expensive step. It is probably not a wise business decision unless you plan on printing metal every day. The costs of just the printer can run between $100.000 and $500.000, plus you will need to add the additional cost of a salary for someone to not only run the printer, but who can also maintain it.

Instead of investing in your own 3D printer, you should probably look into hiring a 3D printing service that can take care of your needs, and companies like Sculpteo and iMaterialise will actually mail you your metal 3D printed parts right to your door. They currently offer 3D printing in the following metal materials:

3D Printed Metals Applications

best metal 3d printer metal applications

You probably don’t even know it but 3D printing is being used more and more for average objects like dental and medical implants. Since they can be adapted to an individual’s needs, they are considered the best available option for patients.

Jewelry has also benefited from the improvement in 3D metal printing technology as it enables manufacturers to switch from lost wax casting and resin 3D printing to direct metal 3D printing. The aerospace industry has also seen an increase in use of 3D printing metal objects and the automotive sector is the next industry where the manufacturers are using 3D printing not just for prototypes, but to make actual car parts

3D printing is still overcoming some obstacles, mostly its high cost, as well as its low production speed which can cause problems for printing 3D metal objects. However, many of the issues that metal 3D printers contend with are similar to any 3D printer that consists of limitation with hardware and software, plus materials and material optimization. Most metal parts generated by a 3D printer are just as strong as components made with traditional methods if not above industry standards in some cases.

Metal 3D Printing At Home

best metal 3d printer at home

For those interested in metal 3D printing at home, there are several obstacles to overcome including the need for very high temperatures to do the printing. This is not a technology that we will see for in home use probably within the next few years. But, as the technology evolves, there will be a lot of growth in these new applications.

It is possible to use added metal powders to a plastic filament that contain a high enough percentage of metal powders but also enough plastic that it can be printed at a low enough temperature that any 3D printer could do it. This combination will still have enough metal to have the feel and look of a metal object. The Dutch company Formfutura has a new metal 3D printing filament that they have increased their ratio up to 85 percent metal powder and 15 percent PLA for more of a metal feel.

If you do plan to try some of these metal 3D printing filaments, you may want to upgrade your 3D printer nozzle depending on your 3D printer’s quality. You may also want to invest in a durable printer hotends that is made of metal and can withstand high temperatures and can be mounted onto most 3D printers. Since metal 3D printing filament can be pretty abrasive, you will have to replace your 3D printer nozzle fairly often. And, don’t forget about investing in a proper finishing process like sand grinding, waxing, greasing, brushing, or coating so that your metal 3D print object can shine.

Available Metal 3D Printing Technology Types

Powder Bed Fusion

Most large companies are using powder bed fusion in their metal 3D printing process meaning that they use an energy source like a laser or another energy beam to fuse atomized, or perfectly round particles, powder to make the layers of the objects.

With eight major metal 3D printer producers in the world, this technology has already made its way into a number of machines and more and more are entering the market all the time. This technology is called DMLS (Direct Metal Laser Sintering) or SLM (Selective Laser Melting).

Binder Jetting

Binder jetting is another professional approach that uses a powder bed where the layers of metal particles are glued together and later sintered or melted together in a high-temperature kiln like with ceramics. Also similar to ceramics is the capability of mixing the metal powder into a metal paste and using a pneumatic extrusion 3D printer to create the 3D objects with the final step being sintered in a kiln. This approach is used by Mini Metal Maker 3D printer which is the only really affordable metal 3D printer on the market.

Metal Deposition

The final method for metal 3D printing is fused filament deposition which is not really possible for a desktop printer. This is a good option for very large industrial metal manufacturers who can deposit metal. The first option is called DED (Directed Energy Deposition) or Laser Cladding that uses a laser beam to fuse slowly released metal powder that is deposited as layers of an object with an industrial robotic arm in a closed chamber.

The second option is called EBAM (Electron Beam Additive Manufacturing) which is a type of soldering process that has a very powerful electron beam that is used to fuse molten metal and a 3 mm thick titanium wire and is shaped into very large metal structures. Only individuals that work for the United States Defense Department will need this type of technology.

Types of Metal Used

Titanium

One of the most commonly used metals for 3D printing is pure titanium, either Ti64 or TiAl4V. Its versatility is an attractive quality as it can print out both light and strong. It is mainly used in the medical industry in creating personalized prosthetics and in the automotive/aerospace industries in making prototypes and parts.

Titanium is used in both binder-jetting and powder bed processes. It does have one catch, it tends to be highly reactive, so it can explode easily in powder form which is why when it is 3D printed, it uses a vacuum or in an argon gas atmosphere.

Stainless Steel

When looking at affordability, stainless steel tends to be the most inexpensive as well as strong metal to 3D print. This is also a versatile metal that is used in many art and design projects as a well as a wide assortment of industrial applications. Because of this type steel alloy, you will find it almost exclusively used in industrial projects due the nickel and cobalt it contains making it have very high elastic properties while remaining hard to break.

Inconel

The superalloy called Inconel is manufactured by Special Metals Corporation. Inconel is made of mostly chrome and nickel and retains a high-temperature resistance which is why it is mainly used for projects in the chemical, oil, and aerospace fields like black boxes on airplanes.

Aluminum

Aluminum is very light and versatile making it a popular metal to use with 3D printing projects. Primarily, it is used as different Aluminum based alloys.

Cobalt Chrome

Containing a very high specific strength, this metal alloy is used mostly to make dental implants, turbines, and orthopedic implants. These are all applications where 3D printing has become a popular manufacturing method.

Copper and Bronze

Mostly used in wax casting processes, copper and bronze are usually not used a lot in powder bed fusion processes as they are not the perfect choice for industrial projects. They are more commonly used in arts and crafts.

Iron

Iron is usually only used as an additive to PLA based filaments like ProtoPasta and TreeD.

Gold, Silver and Other Precious Metals

Precious metals like silver, gold, and platinum are used mostly by powder bed fusion companies. This is a challenging process as the printer must manage the precious powders while maintaining the aesthetic properties of the materials. 3D printing of precious metals is used for medical, jewelry, and electronics applications.

2. Fabrisonic UAM – Ultrasonic Metal 3D Printing

Using Ultrasound Additive Manufacturing Technology, or UAM, Fabrisonic creates 3D print large metal parts with machines that use three-axis CNC mills with an additional welding head for additive manufacturing. With a build volume of 6” x 6” x 3”, metal layers are cut first cut and then welded together with an ultrasound.

The UAM process uses ultrasonic welding to build up solid metal objects into a three-dimensional shape with a series of metal tapes. The process includes periodic machining operations that create a shape detail of the object. A transducer produces vibrations that are transferred to the disk-shaped welding horn that makes an ultrasonic solid-state weld between a base plate and the thin metal tape.

With a continual roll of the horn, the entire tape is welded to the plate with a series of layers welded together onto to create the height of the object. This repeated process occurs until the finished component is created with a final CNC contour milling used to is then used to accomplish the necessary surface finish and tolerances.

Ultrasonic welding gives Fabrisonic its solid-state bond that has been around since the 1960s. The welding process uses ultrasonic vibrations to generate motion similar to friction between two surfaces that are being held together with pressure which can cause plastic deformation and shearing that can cause contaminants and surface oxides to disperse. As the sharpness disappears, the contact between metal and metal is increased and forms a solid bond between the parts because of the heat and pressure.

Fabrisonic has been working on parts for defense contractors, aerospace companies, and a few other high-tech manufacturing companies. They are also anticipating growth and looking to expand in the future.

A dense material that prints easily, the Proto-pasta SSP11701 makes heavy cast metal looking prints that can be sanded, brushed, or polished making it perfect for costumes, jewelry, props, and figurines. Proto-pasta does not require a heated bed, and it uses a direct-drive system with 0.4mm nozzles although a larger, wear resistant nozzle is suggested for more service intervals.

Pros:

  • Nice heavy material
  • Easy to print
  • Sands down smooth with very little effort

Cons:

  • Extruder doesn’t keep up very well

Final Thoughts

The last few years has seen amazing progress in the metal 3D printing industry. Each material has a unique set of properties that can suit a wide range of products including jewelry, medical and dental products, and prototypes. As the technology has developed, it has shown to be in some cases better than what is manufactured by traditional methods and keep in mind it is just getting started.
