Best 3D Printers that Print Metal

Which is the best 3d printer for metal? How much do metal 3D printers cost? Read on to find out.

In this Guide

Metal 3D printers are sought after by both hobby makers and commercial players. There are are number of 3D printers that work with steel and other metals. However, these printers are often expensive because of the advanced technology they employ.

There are also several companies that offer metal 3D printing services. The companies allow you to order 3D printed models online or at their shops.

In this guide, we’ll go through metal 3D printing technology, and highlight the best metal 3D printers on the market. Let’s get started.

History of Metal 3D Printing

The metal 3D printing industry has come a long way. The technology first hit the headlines in 1994 when EOS developed and released the EOSINT M250, which is considered the first 3D metal printer.

However, the machine had a few downfalls, like an inability to melt individual metal particles. As a result, it has to be updated. The updated metal 3D printer was the more efficient EOSINT M270, which was launched in 2004.

Since then, manufacturers have leveraged technological advancements to develop super-efficient metal 3D printers. These modern machines use a technology known as metal additive manufacturing, which makes them faster, more powerful, and generally handy. Also, the 3D printers can handle a wider range of printing materials than their predecessors.

The benefits of additive manufacturing (AM) cannot be denied. The technology is cost-effective and less wasteful than older technologies like wielding. The technology is often used to create complex designs, which can be difficult to develop using other metal fabrication processes like casting, forging, or machining.

Many businesses are jumping into AM because of its advantages. In particular, players in the aerospace and automotive industries are the fastest adopters of AM, and arguably the greatest beneficiaries.

The increasing demand for additive manufacturing has led to the growth of metal 3D printing industry in recent years. The industry is expected to grow from the current $18.33 billion to about $83.90 billion in 2029. Such massive growth means we will see more releases of metal 3D printers.

But before we continue, let’s find out what to keep in mind if you are interested in additive manufacturing.

Choosing an Additive Manufacturing Solution

To find a solution that suits your business, consider your budget and the requirements of your project. Depending on your situation, it may be better to rent rather than buy your own metal 3D printer. In other instances, you may find it economical to outsource the 3D printing of your metal parts.

Below is a primer of metal 3D printing.

Metals and Materials

The most common metal 3D printers are those that handle steel, brass and bronze. Conventional 3D printers prints with 3D filaments like ABS or PLA. These materials are used to produce plastic prototypes, toys, and other advanced structured 3D models.

With metal 3D printers, the materials used as as indicated; metals.

1. Stainless Steel

Stainless steel is one of the cheapest and strongest metals for 3D printing. The versatile metal is used in art and design projects, but also in industrial contexts. Steel contains nickel and cobalt, which give it elastic properties while still ensuring it is hard to break.

2. Titanium

Another widely used material for metal prints is titanium, usually Ti64or TiAl4V. Titanium is versatility and, therefore, can print items of different strengths.

The metal is mostly used in the medical field to make 3D printed prosthetics, and in the automotive industry and the aerospace industry for the production of prototypes and parts.

3. Cobalt Chromium

Cobalt is a high-strength metal alloy used to make dental implants, turbines and orthopedic implants. The metal is commonly used in 3D printing in medicine, and has become a popular manufacturing method.

4. Aluminum

Aluminum is light and versatile, making it a popular metal to use for 3D printing. It is primarily used for aluminum-based alloys.

5. Copper and bronze

Copper and bronze are used mostly in wax casting processes. The two metals are usually not used in powder-based techniques and, therefore, are not the top choices for industrial projects. Instead, they are used more commonly in arts and crafts.

6. Gold, silver and other precious metals

Metals like gold, silver and other precious metals are mostly used by powder-based 3D printers. This is a difficult process because the 3D printer needs to handle valuable powder while retaining the material’s properties.

3D prints of precious metals are used primarily for medical, jewelry and electronics applications.

Application of Metal 3D Prints

3D printed metals have many applications in different industries, including healthcare (dental), consumer (jewelry) and electronics, among others.

Most metal 3D printers are designed for commercial applications. This explains why they are expensive than consumer 3D printers. However, there are also a few printers that are designed for the broader consumer market.

How Metal 3D Printers Work

Printing metal objects works in the same way as printing plastic objects. However, here the temperatures are completely different from what normal plastic filament 3D printers can manage.

The working principle is the same; the printhead sprays out a layer of molten metal, which solidifies and into an object based on the digital file sent to the 3D printer.

Printing With Metal Powder

There is also another method of printing metal that does not require the same high temperatures. With this method, instead of molten metal, metal powder used.

When the metal powder is sprayed, the resulting layers of metal bond together into a uniform mass. This is repeated layer by layer until the entire print item is ready. Depending on the size and complexity of the model, the printing  process may take several hours.

Metal powders can be printed by cheaper machines. However, the material won’t be usable as an end product. For the model to be used, it must put into a melting furnace with a temperature of about 175 degrees for 24 hours, just like ceramics.

After the model has been printed, it is porous and full of air. The air spaces has to be filled with molten metal in the furnace to make the model strong.

3D Printing Metal at Home

Before metal 3D printers become available for the consumer market, there is always the possibility of casting metal into molds. This is an old, well-proven method that has been used for centuries.

But printing some metal items at home would undoubtedly be a lot easier – and more fun! So, when can we expect metal 3D printers for ordinary home use?

Unfortunately, most metal printers currently hundreds of thousands of dollars, which is a high price for printing a few teaspoons and towel hooks. However, metal 3D printers for home use could become reality within a not so distant future. For example, Shapeways allows individuals to print metal models with metal printers.

We will see how long it takes and what the final price will be for the metal 3d printer for the home user. Until then, we have to rely on other external methods.

With that out of the way, here’s a round-up of the best metal 3D printers on the market today.

HP Metal Jet

The HP Metal Jet is among the recently developed Metal 3D printers. It was released in 2018 and quickly gained popularity as one of the world’s most advanced metal 3D printers for mass production.

The quick ascension to fame can be traced back to HP’s extensive experience in the printing industry. Their deep technological knowledge has enabled them to manufacture leading 2D printers.

The breakthrough was followed by a successful exploration of the 3D printing space leading them to develop their proprietary MJF 3D Printing technology, an offshoot of bidder jetting. The technology is believed to be faster than other AM methods

The Metal Jet features the MJF technology, partly explaining its high production capabilities. According to the manufacturer, the printer is about 50 times more productive than other same-level metal 3D printers.

The unit’s overall design is founded on multiple ideas gathered from HP’s long-standing interactions with plastic 3D printers. Remember, plastic 3D printers are economical, so Metal Jet’s printing cost is lower than similar production units.

Consistent quality is assured regardless of the printer’s supersonic printing speed. In fact, the design allows for the production of geometrically complex prints with a printing accuracy of voxel-level 1200 x 1200 dpi 3D.

In order to print, a thermal inkjet squirts droplets of HP binding agent on the bed already overlaid with a thin layer of metal powder. The layering approach is responsible for the printer’s reputation for delivering solid parts. Also, developed components comprise high volumes of metal (up to 99%), reducing material waste. To further cut printing costs, the printer allows the recycling of excess metal powders.

The design also cuts back the need for de-binding. Printing is quickly followed by de-caking then components are sintered in a furnace. The full cabinet-sized build envelope of 430x320x200mm requires about five hours to manufacture products, be it just one product or a group of metal parts.

The Metal Jet is widely used in the automotive industry. In fact, the field was among the first beneficiaries, with Volkswagen and Wilo using the printer to obtain functional metal parts. HP Metal Jet is compatible with stainless steel. However, plans are underway to include Titanium and other powders.

Velo3D Sapphire

Velo3D, the Canadian-based 3D printing company, is the home of several LPBF additive manufacturing systems. The firm also developed Flow print preparation software, giving it an edge in 3D printing.

The Velo3D Sapphire printer is an update of a 2018 Sapphire release which had a small build space (315mm diameter by 400mm height). In other words, the new Sapphire model builds on the previous 2018 printer but with a few changes in its design.  The firm fondly calls it the new generation printer.

One notable change was adopting a bigger build volume. The manufacturer increased the printer’s size from 315mm diameter by 400mm height to 315mm diameter by 1-meter height. The vertical axis increase of 600mm was pretty significant since users could develop meter-long components.

The production unit marked a new era in the world of metal additive manufacturing—it was possible to take on applications that couldn’t be handled before, mainly in the oil and aerospace industries. The printer is also believed to be the tallest closed chamber machine with a laser-powder system. To put it differently, the new gen is a volume production system.

The machine’s print space hosts dual 1-Kilowatt lasers complimented by support-free geometries. It means the Velo3D Sapphire can deliver prints with zero degrees overhangs on horizontal as well as flat surfaces.

Aside from its Support-free printing abilities, in-situ optical calibrations are in place to ensure the machine delivers its promise. As for materials, Sapphire is compatible with Inconel IN718, aluminum F357, Hastelloy C22 (a nickel-chromium-iron-molybdenum alloy), Ti 6Al-4V Grade 5, nickel-based Amperprint 0233 Haynes 282 super-alloy powder, and Hastelloy X.

Farsoon FS121M

Released during the 2021 TCT Asia Trade show, the Farsoon FS121M is among the new entrants in the metal 3D printing market. The manufacturer, Farsoon, is one of China’s most prominent metal AM solutions. They are not limited to metal 3D printers. The firm also has a metal powder production line under its name.

Farsoon offers a wide range of printers, with the FS121M being the smallest on the list. The reasonably priced 3D printer features a small build envelope of 120 x 120 x 100 mm. The machine’s small footprint makes for a space-saving yet highly effective metal 3D printer.

Use cases are slightly inclined towards industries that require quick production of high-quality metal components, like the aerospace and automotive fields. The reason is that the design of the printer includes a 200W Yb-fiber laser plus a digital scanning system. The two support the development of accurate, structurally stable and strong metal parts. The production speed is also impressive.

An open system lends the printer higher levels of flexibility. For one, the manufacturer offers multiple laser spot sizes to choose from. In addition, the printer features different recoating blades as well as a range of powder choices.

Although Farsoon is a developer of metal powders, the FS121M isn’t confined to the firm’s proprietary materials. It can print with different powders including, 17-4PH, Maraging steel, HX, Cu, CoCrMoW, IN718, CuSn10, AlSi10Mg, 316L, Aluminum, Ti64, Ti6Al4V, Tantalum, and Titanium.

Inclusive also is a unidirectional powder feed system, a heat-resistant silicon rubber blade, and a gas advection dust recovery system. Meanwhile, an inert gas supply and protective filter systems deliver adequate safety levels for the product and users.

Best Office Metal 3D Printers

A few factors will go into helping you select an ideal metal 3D printer for office use. First off, the machine should be easy to move around (it can easily slide through the doors).

That has everything to do with weight and size, which determine the printer’s portability attributes. Also, excellent office printers can run without inert gasses or compressed air. We found a couple with the mentioned attributes and a few more attractive features.

Rapidia Metal Designlab

Dubbed the world’s fastest metal 3D printer, the Rapidia Metal Designlab was first revealed in 2019. The time-saving printer employs a paste called HydroFuse to help circumnavigate the traditional 3-step procedure associated with most metal 3D printers.

HydroFuse replaces up to 98% of the binder with water, most of which evaporates during the printing process to cut back on production time. The design also allows you to skip the de-binding process so that prints move from the printer right into the sinter.

Hydro-Fuse is also an environment-friendly paste. It contains ceramic and metal powders instead of polymeric binders that often shrink and produce odors when burnt. In other words, the printer’s design compensates for the shrinkage of parts and unfriendly odors in the office.

Aside from saving money that you’d have otherwise used to purchase a separate de-binding unit, this economical unit features an X1F furnace. This type of furnace eliminates the need for gas during the sintering step. Remember, gas is the second biggest expense after metal.

Instead, you use ultra-high purity Argon in just small amounts instead of hydrogen or forming gas. Argon is way cheaper than other types of sintering gas. Coupled with a relatively low buying price of $ 100,000, the Metal Designlab is pocket friendly.

The machine can print with different materials, including general-purpose ceramic, 17-4PH stainless steel, and 16L stainless steel. The company intends to have copper, Titanium, zirconia, alumina, tungsten chrome carbide, maraging steel, Inconel 625, copper, and H13 tool steel accommodated in the near future.

Markforged Metal X (Gen 2)

The Markforged Metal X is an easy-to-use and pretty fast printer. You can have your designs ready in as few as 28 hours. The production system comprises a compact footprint and utilizes the ADAM (Atomic Diffusion Additive Manufacturing) 3D printing technology.

The ADAM technology was developed by Markforged and is often used to manufacture lightweight metal prints. The process requires bound metal rods that are processed into layers, washed in a de-binder then sintered in a furnace.

In our list of the best office metal 3D printers, the Markforged Metal X has the smallest printing system. The total unit price is $160 000) and includes two processing components ($60 500) plus the printer itself ($99 500).

The printer’s metal feedstock acts as a support for materials. Clean breakaway post sinter is assured since a ceramic interface layer is included between supports and parts. Markforged Metal X is compatible with copper, H13 tool steel, 17-4 PH stainless steel, Inconel 625, A2, and D2 tool steel.

Desktop Metal Studio System 2

The average cost of a 3D metal industrial printer ranges from $420 000  to $1 M. However, Metal Studio System is quite affordable—with about $110 000, you’ll get the entire system, including the furnace unit. Perfect for the office, its two units easily fit alongside each other.

However, they’re large, with the furnace alone weighing about 798kg. Meanwhile, the binder and the printer are 150kg and 97kg, respectively. Considering your space and office arrangement is essential since moving the unit around might not be viable.

The printer uses the BDM (Bound Deposition Method) 3D printing technology which is similar to the popular FFM (Fused Filament Fabrication) technology. In other words, the metal 3D printer extrudes rod-like metal filaments just like the Markforged Metal X.

There’s a difference, however, since Studio System skips the de-binding step, particularly when printing with 316L stainless steel, 17-4PH stainless steel, D2 tool steel or 4140 low-alloy steel. In that case, components are moved to the furnace, which removes the binders. Further heating helps to sinter the parts.

Here are other compatible proprietary materials (remember, these require a separate de-binding unit)

  • Titanium Ti64
  • H13 tool steel
  • 4140 steel

Lastly, removing parts from Studio System 2 is easy. The printer automatically creates seams throughout the support structures during the printing process. It also prints a ceramic interphase between components and the support structure, allowing you to use your hands to remove your prints.

Alternative Best Metal 3D Printers

Is the hunt still on? It must be, that’s the reason why you have come with us this far. This section showcases other metal 3D printers. However, we have different categories, so you can jump right to your preferred list.

Research & Development Metal 3D Printers

Per our above reviews, some 3D metal printers have multiple use cases (R&D inclusive), which means a higher price tag. However, the market offers dedicated units for lab use. They’re designed to help develop and test metal materials specifically.

XXL-Sized Industrial Production Units

Industrial production systems feature generous build envelopes to allow for the development of large-sized metal parts. For that reason, they’re often gigantic. Following are some reliable options:

Hybrid Metal 3D Printers

Hybrid 3D metal printers feature both Additive and subtractive manufacturing technologies. Additive manufacturing systems develop components by adding one layer of the material on top of the other. Subtractive approaches involve the removal of material to create parts.

Combining the two techniques helps to achieve smooth solid surfaced products. Companies like Phillips can install additive capabilities in an existing printer enabling you to enjoy both worlds of 3D printing.

In other words, they save you money since you don’t need to buy a new printer. Some top manufacturers of hybrid systems include:

  • Gefertec, the award-winning German manufacturer of hybrid printers
  • DMG Mori  from Germany and the developer of LASERTEC 65 3D hybrid metal 3D printer
  • Mazak Corporation, the Kentucky-based manufacturer of INTEGREX i-400, one of the world’s largest hybrid systems
  • Matsuura, the Japanese developer of Lumex Avance-25
  • Sodick, headquartered in the United States and manufacturer of OPM250L and OPM350L hybrid metal 3D printers

Is Metal 3D Printing Worth it?

Like other technologies and products, metal 3D printing has advantages and disadvantages. Let’s look at either side of the coin.

Pros of metal 3D Printing

Facilitates the production of intricate designs

: Metal 3D printing provides an avenue for obtaining complex components that’d be impossible to create using traditional strategies. Alternatively, it would mean breaking the manufacturing process into smaller steps to achieve the desired geometry.

Yields lightweight components: Traditional methods are known to yield solid parts. However, they’re often heavy. The technologies used to 3D print metal parts result in somewhat hollow components. Nonetheless, they’re often solid and lightweight.

Convenient: Metal 3D printing delivers a convenience that can’t be found elsewhere. It’s the best way to satisfy on-demand production needs.

Safe and environment healthy: Modern metal 3D printers allow for material recycling. This is particularly true for extrusion-based systems as opposed to powder-based systems since they can accommodate excess material and use it to produce parts. The printing process occurs inside a closed unit keeping the environment clean and safe.

Economical: The economical aspect of 3D printing is bundled up with quick production time, convenience, efficiency and the ability to recycle printing materials.

Constraints of Metal 3D Printing

Pricey:

Metal 3D printers are expensive and so are the printing materials. They also consume considerable amounts of energy. Some units require expert knowledge to operate which means digging deeper into your pockets.

Problems with part structure:  It’s not uncommon for 3D printed parts to delaminate and lose their original structure when subjected to extreme stresses. This is a common problem with components created using FDM-based metal 3D printers.

Design inaccuracies: Sometimes, the final product can be different from the original design. This often happens when the machine is low on tolerance. Although post-processing can help to fix design inaccuracies, it consumes resources like time and energy.

How to Choose a Metal 3D Printer

As the metal 3D printing industry experiences an exponential growth, we’ll see many releases in days to come. The best way to approach a saturated market is by narrowing down your options. Here are guidelines to help you achieve the objective:

  • How fast would you like the production unit to work on your requests?
  • Know beforehand the materials you want to print with
  • Keep in mind the mechanical properties you’d like to see in your prints
  • Consider the ease of use since some production units might require you to hire an expert
  • Check out if the supplier offers consultations services
  • Consider the manufacturer’s customer support avenues. Is the service responsive to distress calls?
  • Are you looking to print for a regulated industry?

Types of Metal 3D Printing Technologies

Just like printer models and manufacturers of 3D metal printers, there are many 3D printing technologies. AM services often market their own proprietary method, with some opting to have a mix of two or more technologies.

Some new innovations, like Meltio’s laser metal deposition and the recently developed cold fusion from SPEED3D, are attracting massive attention. However, the most common additive manufacturing methods are:

  • Laser Powder Bed Fusion (LPBF)
  • Fused Deposition Modeling (FDM)
  • Electron Beam Powder Bed Fusion (EBM)
  • Metal Binder Jetting
  • Cold Spray
  • Direct Energy Deposition (DED)

Laser Powder Bed Fusion (LPBF)

The Laser Powder Bed Fusion is the most preferred 3D printing technique. In fact, it takes up about 80% of the total 3D printing market share. As the name suggests, a laser or more melts one layer of metal powder after the other. The process compels tiny metal particles to fuse, creating ready prints.

The only post-processing process is the removal of support structures unless the mechanical requirements demand smoother surfaces. At that point, some post-process will be necessary to achieve desired attributes.

LPBF technique produces layers that can be as thin as 0.04 mm. As a result, the technique can be used to build complex parts with high resolution. Aside from aluminum, prints can be developed using copper-based alloys, cobalt, nickel, iron, and their composites.

Fused Deposition Modeling (FDM)

Also known as fused filament fabrication, FDM is an extrusion-based printing approach often associated with plastic 3D printing. In the realm of metal 3D prints, the technique can use full-metal filaments or plastic ones infused with metal powder.

The plastic component acts as the binder requiring sintering and de-binding to achieve perfect parts. Although prints can be 98% metal, they’re often porous. Also, metal filaments can be abrasive to extrusion nozzles. As a result, FDM machines often require hardened steel or reinforced extruders.

Also, post-processing means additional costs and a slower production turn-around time. Besides, the process often reduces the overall volume of developed components, affecting the end product’s geometry. With reliable software, however, it is possible to account for the loss and make necessary pre-printing preparations.

On the upside, the technique is pretty cost-effective since it opens up the possibility to 3D print metal components using plastic 3D printing FDM systems. The market offers well-to-do professional plastic 3D printers for USD 10K and below. Perfect examples include the Raise3D Pro 2, MakerBot Method, MakerBot Method X, and Ultimaker S5.

Electron Beam Powder Bed Fusion (EBM)

EBM belongs to the Powder Bed Fusion (PBF) family. Other same-category techniques are Direct Metal Laser Sintering (DMLS), Selective Laser Melting (SLM), Selective Heat Sintering (SHS), and Selective Laser Sintering (SLS).

The PBF family has one thing in common: the methods use either a laser or electron beam to melt layers of material and fuse the particles together.

EBM works more or less like LPBF. However, the difference is that an electron beam, not a laser, handles the melting and fusing processes. The method is ideal for industries interested in quickly producing large 3D metal prints. However, the EBM isn’t as accurate as Selective Laser Melting (SLM).

On the upside, EBM leverages the power of high temperatures and a vacuum environment to create stress-relieved parts with attributes like those you’d find in wrought iron.

Metal Binder Jetting

The metal binder jetting technique is the fastest in the PBF family. As the name suggests, a binder jetting printer distributes layers on the printing material on the print bed. Meanwhile, a jetting head deposits the binder to create the desired geometry.

Aside from its lightning-speed printing abilities, metal binder jetting is inexpensive and offers higher material flexibility. The perks partly explain why it’s becoming more popular than SLM.

However, speed is limited to the printing stage. More time is required for post-processing, including de-binding, sintering, de-powdering, infiltration, and annealing. Overall, the technique requires more time than other AM methods.

Cold Spray

Cold spray was initially developed to help with coating tasks up until 2000, when it was adapted by AM services and used to 3D print metal parts. Unlike other metal 3D printing methods, cold spray is devoid of thermal power. Instead, metal powders are sprayed at high-speed to fuse the particles together.

The process features negligible levels of thermal stress minimizing the chances of creating deformed parts. Cold spray easily achieves precise geometries and can manufacture thick parts faster than other printing techniques.

The technique is helpful in on-location repair and restoration of metal parts and quick manufacturing of replacement parts. The mentioned use cases have made it a cost-saving 3D printing method since cold spray can thwart interruptions. Also, repairing is way cheaper than replacing a whole part. As a result, cold pray has become the most preferred metal 3D printing option in the oil, gas, and military fields.

Direct Energy Deposition (DED)

Direct Energy Deposition technology is pretty broad. It’s also known as Direct Metal Deposition (DMD), Laser Engineered Net Shaping (LENS), Electron Beam Additive Manufacturing (EBAM), Laser Engineered Net Shaping (LENS), or 3D Laser Cladding, depending on the application method.

Depending on the heat source, DED is further classified into five groups below.

  • Wire-based DED: While wires are the primary materials, the source of heat can be a laser, electron beam or plasma
  • Powder-based DED: Laser or electronic beams are used to heat metal powder in order to create parts
  • Electron beam-based DED: The feedstock here is metal powder, while an electron beam provides energy
  • Laser-based DED: Laser is the only energy source
  • Plasma or Electric arc-based DED: An electric arc provides the energy required to create a molten pool from wires

Regardless of the DED method used, the production process is similar to welding. A nozzle deposits the metal powder or wire while, at the same time, a focused energy source melts it. In other words, the two processes happen simultaneously.

In general, wire is economical as far as material use is concerned. Metal powder offers greater accuracy in deposition. DED printers can achieve layer thickness of 0.25mm to 0.5mm, and cooling can be super-fast—1000 to 5000 °C per second. Direct Energy Deposition can be used to repair parts, add material to existing ones, or print metal 3D prints from scratch.

Best Metal 3D Printing Services

Sometimes, outsourcing printing services can make more business sense than investing in a production unit. The reasons can vary from space limitations, a busy schedule, budget, and human resource constraints, or minimal printing needs.

Whichever the reason, you can order parts online to satisfy your printing needs. In most instances, you’ve to upload your request for review, after which the AM service sends you a quote. The general procedure includes the following steps:

  • Create an account with the 3D metal service and sign in
  • Upload your model to the manufacturer’s site
  • Specify the number of parts you want to be printed, the material, and finishing details
  • Receive the quote
  • Place your order if content with the price

Our below list of additive services has invested in high-end metal printers in order to reach a broader client base. They also have on-site 3D printing experts to deliver per your expectations. If you’re new to metal 3D printing, they offer guidance to help you get your bearings.

Metal 3D Printing Materials

The AM market offers different types of 3D printing materials. Each complements a specific printing method. Resin and metal sheets are quite uncommon. They’re mainly used in lamination-based production systems. Following are the popular 3D printing materials:

  • Wire
  • Metal powder
  • Filament

Best Applications for Metal AM Production Systems

Metal 3D printing is no longer reserved for rapid prototyping and concept modeling. The industry has expanded to include small batches in the consumer category to large-scale production. In short, the possibilities are limitless.

AM systems are widely used for tooling, repair, and replacement of parts and for creating new components from scratch. Whatever the reason for wanting to venture into the AM industry, it’s best to use traditional methods for simple tasks to save on costs. It means reserving AM systems for complex jobs like rapid prototyping and mass customization needs or for developing complex geometries

FAQs

How expensive is a metal 3D printer?

The cost can be anything from USD 30 000 to over USD 1M for premium grade industrial metal 3D printers. Aside from the production unit, printing materials and post-processing costs like tools can significantly alter the overall price. Nonetheless, you can opt for plastic 3D printers, which are pocket-friendlier. Keep in mind that their application is limited.

Are 3D metal printed parts brittle?

No. In fact, metal 3D prints can be stronger than traditionally developed parts. The additive manufacturing method and the printing environment often determine the strength of the final product.
