What is Direct Metal Laser Sintering?

Direct Metal Laser Sintering or DMLS for shortis a 3D laser-based additive manufacturing method. It consists of creating metal additively by sintering fine metal powders, to fuse them together locally. This 3D printing technology allows to create fully dense metal parts, with no upfront setup or tooling costs. 

DMLS technology is suitable for producing meticulous metal parts, with exceptional mechanical properties and precision. With the help of our metal experts, we deliver highly precise metal parts with complex features, using high-calibre DMLS machines and a variety of materials.

Direct Metal Laser Sintering (DMLS), How Does It Work?

 

Pre-processing

The first step is to create a digital 3D model of the part that has to be printed, using a Computer-Aided Design (CAD) software and STL file. The technician uses this 3D model to properly align the geometry and add support structures. The digital model is then loaded into a slicing program that will analyze it and create instructions that the 3D printer will use to build the finished part layer-by-layer. 

 

Support Structures

Support structures are often used to anchor the part to the build platform, and draw some heat away to allow for stable, controlled cooling, and prevent warping. DMLS parts move around in the build envelope if not properly secured to the build platform. This movement  can cause failures in part accuracy and could potentially lead to machine crashes. 

Furthermore, complex designs require more support as they may contain more arches, curves, large holes and overhangs. Nevertheless, using support structures does not impact the quality of the print. They are made from the same material as the part and will be manually clipped off in post-processing, leaving no marks in the final printed part. 

 

3D Printing

The print run is now initiated. This step begins with heating the build chamber to just below the material’s melting point and filling it with inert gas in order to prevent the oxidation of the metal powder and preserve the quality of the metal. Similarly to the SLS process for plastics, a thin layer of powder is then spread across the building area. 

Following the points defined by the CAD model, a powerful laser in the 3D printer starts to sinter the powder. Once the first layer of the 3D printed part is done, the build platform lowers itself by one layer height and the recoater blade moves across the platform to deposit the next layer of powder into the inert build chamber. 

The process of distributing the metal powder, evenly, through the build platform and the laser sintering the powder into solid, is repeated until the part is completed. 

 

Post-processing

After the build process is done, the part needs to cool down to room temperature. Removing the loose powder, manually, follows. The excess of powder can be reused in future printing operations, minimising the waste of materials. 

Before detaching the part, the appropriate heat-treat cycle is administered to relieve any stresses. The final steps include removing the part from the build plate, then removing support structures. 

The final metal piece may need to undergo varying levels of finishing like bead blasting and deburring for function and esthetic requirements, because the printing process creates parts with grainy surface texture. 

3D Metal Printing Applications

Direct Metal Laser Sintering (DMLS) is revolutionizing many industries because it can produce customized parts with few restrictions to geometrical designs. Unlike CNC machining or casting, our DMLS printing service is very advantageous as it allows our clients to have design freedom and build parts in a shorter time.

Aerospace

Strict thermal, weight reduction and complex, dense parts are all requirements in Aerospace industries. These requirements are easily achievable with the DMLS printing technology. From Aircraft Rapid Prototyping to Spacecrafts and Rockets manufacturing, Direct Metal Laser Sintering (DMLS) allows to build intricate, incredibly durable, consistent and cost-effective metal parts that are difficult or impossible to fabricate with other manufacturing methods.

Components of satellites and rockets must perform consistently at high temperatures. Our DMLS machines are capable of producing flight-qualified, end-production parts for aerospace applications.

Prostheses and Implants

DMLS technology is used in the fabrication of human implants directly from computer-aided design (CAD). It helps meeting the patient’s specific anatomic needs which reduces the risk of problems normally caused by ill-fitted implants. Customization of parts is a great benefit provided by DMLS technology.

Custom implants make the surgery less complex and reduce the need for secondary revision procedures such as flap repositioning. Moreover, CAD surgeries have the potential not only to reduce surgical time, but also, to reduce prosthesis-related complications. Direct Metal Laser Sintering (DMLS) has proven to be a useful way to build prostheses for major reconstructive surgeries.

Components and Antennas

Waveguide-based components and antenna-feed chains are complex radio-frequency assemblies, used in applications such as imaging, satellite communications, navigation and earth observations. DMLS technology offers advantages in terms of the realisation of complex shapes, lighter weights, through hollow or lattice structures, with enhanced structural strength.

Microwave and antenna engineers can now use DMLS printing technology to design waveguide-based components, with high levels of efficiency and accuracy. This technique offers the flexibility to fabricate complicated microwave structures and antennas with good reliability and high precision.

Automotive

Due to a wide range of applications, materials, flexibility and low complexity in the manufacturing process, DMLS technology is transforming the automotive industry. This 3D printing method contributes in speeding up the design phase since it’s used in early stages to create miniatures components. This process enables testing of forms and functionalities for designers.

Using DMLS manufacturing technology in the automotive industry not only allows producing advanced designs and shapes, but it also raises the capabilities to produce consolidated, durable parts in a very short time. Optimized geometry enables a weight reduction in the final part which is required in producing cars with an internal combustion engine.

Dentistry

Following the patient’s dentition and oral anatomy, strong and durable bridges, crowns, partial dentures, and dental prosthetics can be custom-made, using DMLS. This technology guarantees a density of 99+ % which makes dental prosthetics highly accurate and very consistent. Besides being moderate in weight, computer-aided design (CAD) precision gives excellent fitting, high strength and rigidity, allowing a secure crown fixing.

Compared to conventional casting procedures, DMLS allows dental technicians to dramatically increase the number of crowns and bridges created in 24 hours, with higher quality and efficiency. This means that, for the dentist, time is reduced in both the chair side and the dental laboratory.

Rapid Prototyping

Rapid prototyping is used to test the efficiency of a part and validate the final design and manufacturing. Direct Metal Laser Sintering (DMLS) technology is perfect for building fully dense metal parts while creating a time advantage. Moreover, it offers design freedom in the case of complex structures and improves the functionality of the prototypes, which would not have been possible with conventional prototyping methods.

Furthermore, DMLS can be used for rapid tooling, printing versions of the model at different design stages, and being able to test and optimize the tool much faster. Rapid tooling helps reduce development and production steps, which leads to faster time-to-market and lowers costs.
