The generative design goal is to obtain as many answers from computer technology as possible to broaden the possibilities of how your design will be.

The designer's suite will prove a key tool when working in the design of multiple materials as well as the use of stainless steel.

The material gives you the ability to produce durable parts which can be difficult to achieve using other manufacturing methods. “This material is in some cases 20 to 50 times stronger than our next strongest composite or polymer. So, its physical characteristics are somewhat remarkable," says Felipe Castaneda, Creative Director for Maker.

The ability to 3D print in stainless steel will likely increase the potential of this high chromium and low carbon alloy. This material possesses vital functions in several industries for more than a century. It builds parts greater in complex design complexity than machine parts without sacrificing its superior materials. Stainless steel 3D printed parts are robust and light with good detail. Depending on the chosen stainless steel materials components can tolerate temperatures up to 800oC. It is no surprise that this high-performance steel-3D printed material is widely used for industrial applications such as aerospace, auto and manufacturing.

How does metal 3D printing work?

Metal powder 3D printing is using a laser to create a thin film using metallic materials and metal powder. The same laser which has been used for laser sintering binds up powder together selectively in powder beds. The support structure is automatically created in the same material simultaneously and in parallel, but later manually discarded. Once complete the part undergoes heat-treated and undergoes a process of creating the part and the support structures.

Stainless Steel powder 3D printing methods

Stainless Steel 17-4PH - Fused Deposition Modeling [FDM] - The powder is deposited at the surface from a building box where a print head is moved through this cradle and selectively dripping the adhesive. A heating lamp is used for drying the surface of the model as outlined by the binding agent. To add another layer a new coating was spread and the process repeated. The 3D version is constructed layer by layer until completion and is dried in ovens to strengthen the binding layer. SLM consists of selective sintering (heating and melting) and melting of stainless steel powder using a high-power laser to fuses the granule.

What is Stainless Steel 316L?

316LS stainless steels print accuracy is based on a high resolution and accurate light sources 30-40 m. Unlike polymer powder sintering stainless steel requires the addition of auxiliary bases to adhere the material to the Board and to strengthen distinctive geometries such as overhangs. The material is strong resistance to corrosion and is distinguished by its ductility. It's a great candidate for implementation in multiple industries like medical fields for surgery help with endoscope surgery or orthopaedics in the aerospace industry for the production of excellent mechanical properties; in automobile industries for corrosion-resistant materials.

Machine components

There are various metal powders and metal powder types, such as stainless steel 316L powder, alloy metal powder and metal titanium alloys used for metal 3d printing. The metal parts manufactured through this process need heat treatment before they provide the desired properties. All metal parts should be cleaned to remove any excess support material and metal powder after the metal 3D printing process.

Stainless steel 316L metal powder is metal 3D printing material with high resistance to corrosion. This metal has excellent ductility, which means it can be bent without breaking. It also has good thermal properties, meaning that it can withstand higher temperatures than some other metals. Stainless steel 316L metal powder is the perfect candidate for implementation in industries like medical fields for surgery help with endoscope surgery or orthopaedics in the aerospace industry for the production of excellent mechanical properties; in automobile industries for corrosion-resistant materials.

Sculpteo uses the technology of DMLS (Direct Metal laser sintering), 3DMITECH  uses the technology Binder Jetting [BJT] a technique on an EOS M280 laser printer for printing from steel. 3DMITECH use also technology Fused Deposition Modeling [FDM] to print metal Stainless Steel 17-4PH .The walls of your design must have a maximum thickness of 2 mm to ensure that the structure does not crack. Clearance is 0.2 mm and depends on the diameter of your object. For successful 3D printing an imposed minimum separation between objects must be maintained to allow any accumulated dirt to be sandblasted out. The minimal precision of individual details is largely determined by the resolution of printers. It is unusable if Stainless Steel contains the material of 3D printing.

Stainless Steel printing

Metal 3D printing is on the upswing. Researchers from a number of universities, including Oregon State University, Ames National Laboratory, Lawrence Livermore National Laboratory, and Georgia Tech University, made a major breakthrough in 3D printing 316L in late 2017. They were able to produce a low-carbon 316L that was strong enough for military and maritime.

conclusion

3D print stainless steel is the latest technological advancement in metal additive manufacturing. The generative design goal is to obtain as many answers from computer technology as possible to broaden the possibilities of how your design will be. Designer's suite will prove a key tool when working in the design of multiple materials with this material and also using stainless steel, which gives you the ability to produce durable parts that are difficult to achieve through other methods.

Stainless Steel 316L , Stainless Steel 17-4PH - has been used for more than 100 years due to its high corrosion resistance and strength properties such as ductility and tensile strength! It offers an excellent option for industries like aerospace, automotive, medical fields or domestic products sectors because it resists dirt accumulation and doesn't rust easily even if it is exposed to saltwater.
