What 3D Printers Can Print Metal?
Metal 3D printing has transformed the manufacturing landscape, allowing individuals and businesses to create robust, intricate, and sometimes even impossible structures with metals. But not all 3D printers are created equal—only certain models and technologies are capable of printing with metal. In this guide, you’ll learn everything you need to know about which 3D printers can print metal, how these machines work, what it takes to use them, and practical tips to get started.
Types of Metal 3D Printing Technologies
Metal 3D printing is not a one-size-fits-all process. There are several distinct technologies, each offering unique advantages, limitations, and use cases.
1. Powder Bed Fusion (PBF)
Powder Bed Fusion is one of the most widely used technologies for metal 3D printing. It involves spreading a thin layer of metal powder and fusing it layer by layer using a high-energy heat source such as a laser or electron beam.
- Selective Laser Melting (SLM): Fuses powder fully to produce dense, strong parts.
- Direct Metal Laser Sintering (DMLS): Similar to SLM, widely used for both prototyping and end-use parts.
- Electron Beam Melting (EBM): Uses electron beams instead of lasers, often for titanium alloys.
Best for: High-performance aerospace, automotive, and medical components.
2. Binder Jetting
Here, a binding agent selectively glues metal powder, layer by layer. The green (raw) part is later sintered in a furnace to achieve full strength.
- Pros: Faster, often more affordable than PBF.
- Cons: May require additional post-processing.
Best for: Complex parts in medium to large batches.
3. Directed Energy Deposition (DED)
This technology feeds metal powder or wire directly to a heat source (laser, electron beam, or plasma arc) and deposits material where needed.
- Main use: Repairing or adding features to existing metal components.
- Scale: Typically used for larger parts.
4. Metal Fused Filament Fabrication (Metal FFF/Metal FDM)
A hybrid of traditional FDM printing, these machines use a filament loaded with metal particles and a binder. After printing, the “green” part is washed and sintered to remove the binder and densify the metal.
- Pros: More accessible, lower cost, easier to operate.
- Cons: Often less dense and robust than PBF-printed parts.
Best for: Prototyping, schools, labs, small-batch production.

The Benefits of Metal 3D Printing
Why is metal 3D printing such a game changer? Here are some compelling advantages:
- Design Freedom: Print internal channels, lattice structures, or parts impossible with traditional methods.
- Rapid Prototyping: Accelerate product development by quickly testing metal prototypes.
- Part Consolidation: Replace assemblies of multiple parts with a single printed piece, reducing manufacturing steps and potential points of failure.
- Lightweighting: Create strong, lightweight components for industries like aerospace.
- Customization: Produce bespoke implants, tools, or components tailored to unique needs.
Key Challenges and Considerations
While exciting, metal 3D printing is not plug-and-play. Here are some challenges you should plan for:
- High Initial Investment: True metal-capable machines (especially for powder-bed fusion) cost from tens of thousands up to several million dollars.
- Expertise Required: Handling metal powders, machine calibration, and part post-processing demand specialized knowledge.
- Post-Processing: Most metal-printed parts require support removal, heat treatment, or surface finishing.
- Safety: Metal powders can be hazardous. Proper ventilation, personal protective equipment, and training are essential.
- Material Costs: Metal powders and filaments are much pricier than standard plastic materials.
Practical Tips and Best Practices
Thinking of diving into metal 3D printing? Here’s some advice to make your journey smoother:
- Choose the Right Technology
- If you need top structural performance, go for powder-bed fusion.
-
For prototyping or smaller-scale projects, Metal FFF or binder jetting may suffice.
-
Factor in the Full Workflow
-
Remember: You’ll need to budget and plan for post-processing (heat treatment, support removal, and finishing).
-
Training and Safety
- Invest in operator training.
-
Use appropriate safety gear, and devise protocols for powder handling and waste disposal.
-
Start Simple
-
If you’re new, consider a solution that uses metal filaments (like Markforged or BASF’s Ultrafuse) to minimize complexity.
-
Work with Experts
-
Partner with service bureaus or consult with experienced professionals before investing in expensive machines.
-
Batch Production for Savings
- Metal 3D printing can be costly for one-offs, but batch production helps lower per-part costs.
Metal 3D Printing Costs and Price Tips
Understanding costs is crucial before you commit to metal 3D printing.
Initial Machine Costs
- Industrial powder-bed fusion machines: $200,000–$1,000,000+
- Desktop or entry-level systems (Metal FFF): $60,000–$200,000
- Conversion kits/metal filaments for FDM printers: Few thousand dollars for the printer; $200–$500+ per spool for filament
Material Expenses
- Metal powder: $300–$700 per kg (prices can soar for specialty materials)

Frequently Asked Questions (FAQs)
1. Can my home 3D printer be upgraded to print metal?
Most desktop FDM/FFF plastic printers can’t directly print solid metal parts. However, you can use metal-infused filaments (like BASF Ultrafuse) with compatible machines and then send the printed parts for debinding and sintering. True industrial-grade metal printing isn’t possible on standard home printers.
2. What’s the difference between SLM, DMLS, and EBM metal 3D printers?
All these are powder bed fusion technologies. SLM (Selective Laser Melting) melts metal powder with a laser for fully dense parts. DMLS (Direct Metal Laser Sintering) is similar, sometimes with slight differences in material handling. EBM (Electron Beam Melting) uses electron beams instead of lasers and operates in a vacuum, which is especially useful for reactive metals like titanium.
3. Is metal 3D printing safe?
Metal 3D printing involves hazardous powders and high temperatures. Stringent safety measures, including personal protective equipment, proper ventilation, and training, are necessary to prevent exposure and accidents. Small-scale Metal FFF systems are generally safer but still require caution.
4. How expensive is it to 3D print metal objects?
Metal 3D printing is costlier than plastic 3D printing. The largest expenses are machine purchase, metal powder or filament, and post-processing equipment. Single parts from service bureaus can range from $100 to several thousand dollars, depending on size and complexity.
5. What metals can I print with a metal 3D printer?
Common printable metals include stainless steel, aluminum, titanium, Inconel (nickel alloys), cobalt-chrome, copper, and tool steels. Availability depends on your chosen printer and technology.
In Summary
Metal 3D printers come in various forms, from evidence-based industrial giants to more accessible desktop models. The right choice depends on your needs, budget, and experience. While metal 3D printing offers unmatched design flexibility and production possibilities, it demands a thoughtful approach, from technology selection to safety and post-processing.
Whether you’re a seasoned engineer or a curious innovator, metal 3D printing opens up remarkable new ways to turn your ideas into reality. By understanding the technology, weighing the costs, and planning wisely, you can harness the power of metal 3D printing for prototyping, production, or custom projects.
