Can a 3D printer print steel?

The Power of Steel. Like aluminum and titanium, stainless steel can be used to 3D print complex designs that are normally impossible to accomplish. It can also produce large objects, owing to its strength. Thanks to 3D printing technology, stainless steel is soon to be put into even more uses.

Which material is used in DMLS process?

DMLS parts are made with powdered materials like aluminum, stainless steel and titanium, as well as niche alloys like MONEL® K500 and Nickel Alloy 718.

Can 3D printers print metal objects?

Metal 3D printing, also known as Direct Metal Laser Sintering (DMLS) and Direct Metal Laser Melting (DMLM) is an additive layer technology. Metal 3D printing materials include stainless steel, cobalt chrome, maraging steel, aluminum, nickel alloy and titanium.

How does direct metal laser sintering DMLS work?

SLM heats the metal powder until it fully melts into a liquid. DMLS does not melt the metal powder, so less energy is needed. Sintering heats particles enough so that their surfaces weld together. The working material for this 3D printing process is finely powdered metal.

How strong are DMLS parts?

Fusing together fine layers of powder, DMLS has the ability to produce very strong and accurate parts (± 0.05 mm/0.002 in.), from simple to complex geometries. This makes it a great alternative to machining parts.

Which metal can be print using SLS technology?

SLS 3D Printing Materials The most common material for selective laser sintering is nylon, a highly capable engineering thermoplastic for both functional prototyping and end-use production. Nylon is ideal for complex assemblies and durable parts with high environmental stability.

What is the difference between DMLS and SLM 3D printing?

While the process is the same, DMLS is used when alloys are being created for the metal parts, while SLM is used to create single element metals, such as with titanium or aluminum. SLM Solutions 280, an SLM printer, next to the 3D Systems ProX, a DMLS 3D printer.

What metal powders are used in DMLS 3D printing?

Though 3D printer manufacturers are continuously innovating to create new metal powders, there are a number of main metal powders used in DMLS 3D printing. These include aluminum and titanium, though others such as Cobalt-chrome, Stainless steel and Inconel are also commonly used. We have a separate guide to 3D printing aluminum.

What is direct metal laser sintering (DMLS)?

Direct Metal Laser Sintering was patented by ERD and EOS back in 1994, before EOS pioneered the technology in their DMLS 3D printers. Though the patent didn’t come about until 1994, preliminary research conducted on what would eventually become DMLS can be traced back to the late 1970s. A part created using Direct Metal Laser Sintering.

What materials are used in laser sintering?

Direct Metal Laser Sintering / SLM Materials Though 3D printer manufacturers are continuously innovating to create new metal powders, there are a number of main metal powders used in DMLS 3D printing. These include aluminum and titanium, though others such as Cobalt-chrome, Stainless steel and Inconel are also commonly used.
