Here at Matrix Technology, we build end-to-end Selective Laser Melting (SLM) solutions that fit your exact needs. Whether you require a compact R&D system or a massive dual-laser industrial production platform, our machines deliver near-fully dense metal parts (≥99.9%). The result? Mechanical properties that easily rival traditional forging.
How Does a SLM Printer Work?
Curious about how digital files become solid metal? It’s driven by precise physics and digital-to-physical workflows.
Here is how the magic happens:
Digital Preparation: We use Voxeldance Additive software to slice your 3D CAD models (STL/SLC/JOB) into incredibly thin layers—down to just 0.02mm.
Atmospheric Control: Oxygen is the enemy of hot metal. We flood the build chamber with inert Nitrogen or Argon gas, dropping oxygen levels safely below 100ppm.
Precision Recoating: An automated bottom-up electrical cylinder pushes metal powder up. A precision blade then spreads it perfectly across the build plate.
Selective Melting: A high-powered fiber laser traces the exact shape of your part. It completely fuses the metallic particles into a solid layer. The bed drops, and the cycle repeats!

Compatible Metal Powders for SLM Printers
Your Laser Powder Bed Fusion 3D printer is only as good as the material inside it. Highlighting material versatility is crucial for modern manufacturing.
Here are the top metals you can print with today:
Titanium Alloys (Ti6Al4V): The industry standard for lightweight aerospace brackets and highly biocompatible medical implants.
Aluminum Alloys (AlSi10Mg): Incredible thermal conductivity. Perfect for automotive weight reduction and complex heat exchangers.
Stainless & Tool Steels: Ideal for creating conformal cooling channels in injection molds. Say goodbye to tooling bottlenecks!
Superalloys: Think CoCr, Tantalum, and Nickel alloys. Built to survive extreme heat and highly corrosive environments.
Reflective Metals: Pure copper and precious metals shine here. Our MA100G’s green laser technology handles them with spatter-free ease.
Top Industrial Applications for Matrix SLM Machines
How are real-world innovators actually using these machines?
Aerospace & Aviation: Engineers use SLM to print complex fuel nozzles and lightweight lattice structures. This consolidates dozens of separate parts into one unbreakable assembly.
Medical & Dental: Surgeons rely on metal 3D printing for patient-specific spinal implants and custom orthopedic joints. Dentists use it for ultra-precise frameworks.
Note: Professional manufacturing tool only. Always consult a physician for medical diagnosis and treatment.
Automotive & Motorsport: Race teams print custom suspension parts and complex tire molds with intricate sipes to shave seconds off their lap times.
Molding & Tooling: Injection molding relies on perfect temperature control. SLM printers create complex conformal cooling channels directly inside tool steel molds. This slashes your cycle times and significantly boosts final part quality.
Jewelry: Designers are pushing the boundaries of traditional casting. Using our specialized green laser technology, you can print intricate, highly detailed custom pieces directly in precious metals like gold, platinum, and 925 silver.
Manufacturing: Stop waiting on delayed supply chains. From on-demand rapid prototyping to producing heavy-duty custom jigs and versatile fixtures, industrial metal 3D printers keep your daily operations moving fast.
What is Selective Laser Melting (SLM)?
Let’s get back to basics. What exactly is this technology?
Selective Laser Melting (SLM), also called Laser Powder Bed Fusion (LPBF), is an advanced additive manufacturing process. A high-power laser selectively melts and fuses metallic powders layer by layer, directly from a 3D CAD file.
Why is this better than traditional machining? You eliminate tooling costs completely. You gain total geometric freedom to design impossible shapes. Plus, you drastically reduce material waste because you only consume the metal you actually melt.
The Complete Matrix Ecosystem: Post-Processing & Handling
An industrial metal 3D printer doesn’t work in a vacuum. SLM parts need proper post-processing to hit those tight final tolerances.
Matrix provides an end-to-end ecosystem to support your entire production floor:
Thermal Stress Relief: Use our Vacuum Annealing Furnaces and Drying Ovens to relieve internal printing stresses and optimize part toughness.
Powder Management & Safety: Reclaim up to 100% of your unfused powder. We supply Vibratory Sieves and Explosion-Proof Vacuums to keep your material costs incredibly low.
Subtractive Surface Finishing: Get that perfect final finish. We offer Wire EDM, Band Saws for exact support structure removal, and heavy-duty Sandblasting Machines.

Frequently Asked Questions (FAQs)
Is an SLM 3D printer expensive to run?
Metal powder costs are steadily dropping. Plus, our advanced powder recycling systems safely reclaim almost all unfused metal, making SLM highly cost-effective for complex, low-volume production.
What is the difference between SLM and DMLS?
Both are laser powder bed fusion technologies. SLM fully melts the metal powder into a homogenous solid part, while DMLS typically works with metal alloys and sinters them. Today, the terms are frequently used interchangeably in the industry.
Is metal 3D printing sustainable?
It offers potential benefits like reduced material waste (additive vs. subtractive), creating lightweight designs that improve fuel efficiency (e.g., in aerospace), and enabling localized manufacturing. However, energy consumption during printing and powder production are factors to consider. Life cycle assessments are complex but often show advantages for complex, low-volume parts.
