Materials for DMLS 3D Printing
We offer a range of metal powders for DMLS printing, including stainless steel, aluminum, titanium, and more. Each material is selected for its mechanical strength, durability, and suitability for complex geometries.
Aluminium
Lightweight and corrosion-resistant, aluminum is ideal for parts that need strength without added weight. It’s widely used in automotive, aerospace, and consumer electronics.
- Aluminium Al-Si10Mg
Cobalt Chrome
Known for its hardness and wear resistance, cobalt chrome performs well in high-temperature and medical applications. It offers excellent biocompatibility and strength.
- Cobalt chrome / CoCr
Steel
Steel offers solid mechanical strength and good machinability. It’s suitable for durable end-use parts, tools, and functional prototypes.
- Tool steel 1.2709 / MS1
Stainless Steel
Stainless steel combines strength, ductility, and corrosion resistance. It’s a versatile choice for industrial, medical, and food-grade components.
- Stainless Steel 17-4PH / 1.4542 / X5CrNiCuNb16-4
- Stainless Steel 316L / 1.4404 / X2CrNiMo17-12-2
Inconel
A nickel-based superalloy with high thermal and chemical resistance, Inconel is perfect for aerospace and energy applications. It maintains strength in extreme environments.
- Inconel 718
Titanium
Titanium delivers an excellent balance of strength, low weight, and corrosion resistance. It’s commonly used in aerospace, medical implants, and high-performance parts.
- Titan Grade 5 / 3.7164 / 3.7165 / Ti-6Al-4V
Finishing Options for DMLS 3D Printing
As-printed
Support structures are carefully removed, followed by media blasting to create a clean, uniform surface finish.
Bead blasting
Bead blasting uses a pressurized stream of fine plastic or glass beads to smooth and refine the part’s exterior.
Custom
Send us your inquiry with the finish you need, and our team will review it quickly and follow up with details.
DMLS Resolution (Layer Thickness) Options
Layer thickness refers to the height of each printed layer in the 3D printing process. It directly affects surface finish, detail resolution, build speed, and part strength. Koonze Model offers three options to suit different project needs:
- Economy (>60 µm): A faster, cost-effective option ideal for simple geometries and non-critical parts. Lower resolution and strength make it best for basic prototypes or concept models.
- Standard (40–60 µm): A balanced choice for general use, offering a good mix of surface quality, strength, and build time. Suitable for most functional and visual prototypes.
- Fine (<40 µm): Offers high-resolution detail and excellent surface finish. Best for complex parts requiring precision and mechanical strength, despite longer build times.

Pros & Cons of DMLS 3D Printing
| Advantages | Considerations |
|---|---|
| Supports Complex Designs: Enables production of intricate geometries that traditional machining can’t achieve. | Rougher Surface Finish: Typically has higher surface roughness compared to CNC-machined parts. |
| Strong Material Performance: Printed parts retain excellent mechanical properties thanks to high-quality metal powders. | Higher Cost: DMLS tends to be more expensive than other manufacturing methods. |
| Post-Processing Flexibility: Compatible with various mechanical and electrochemical finishing methods to enhance final parts. | Build Size Limits: Maximum part size is restricted by the build chamber of the printer. |
