3D Metal Printing / Direct Metal Laser Sintering (DMLS)

How does Metal 3D Printing work?

The Direct Metal Laser Sintering (DMLS) process is an emerging metal 3D printing technology in which 3D CAD data is converted into physical solid models, layer by layer, by selectively fusing areas of metal powder with a powerful laser.

Initially the DMLS machine laser will be aimed onto a bed of metallic powder and it will draw the support structures required onto the build plate, then it draws the part itself. Each time a layer is sintered, the build plate will drop and a recoater blade will move across the platform to deposit the next layer of powder to be sintered. This process repeats layer by layer until the entire part has been built. When the build is completed the build platform is removed and loose powder is brushed away. While the parts are still attached to the build plate they may receive heat treatment or shot peening. Parts are then typically removed from the build platform using either a saw or EDM. Parts will then ready to be post machined, barrel rumbled or hand finished.

“name”: “4. What types of metals can be used in 3D printing?”,
“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Common metal materials used in 3D printing include stainless steel, aluminium, and titanium. Each material has unique properties that make it suitable for specific applications. Titanium, for example, has a high strength-to-weight ratio which makes it ideal for aerospace, automotive, and medical applications where lightweight and durable components are crucial. Stainless steel on the other hand offers excellent corrosion resistance and is often used in industrial, marine, and food processing environments.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Metal 3D printed parts can have mechanical properties comparable to or even better than those of traditionally manufactured parts, depending on the material and process used. Heat treatment during post-processing can further improve strength and durability, resulting in components that are stronger and denser than wrought materials.”

“name”: “7. What is the typical lead time for a metal 3D printed part?”,
“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Lead times for metal 3D printed parts can vary depending on the complexity of the design, material used, and post-processing requirements. However, metal 3D printing generally offers faster lead times compared to traditional manufacturing methods. Small, straightforward projects will typically be completed within 4-6 days, whilst larger and/or more complicated projects will normally be completed within a few weeks. This makes metal 3D printing ideal for both low-volume production and rapid prototyping.”
