Though there are several traditional techniques to manufacture aluminum parts and prototypes, 3D printing has prevalently gained significance over the years. Days are gone when heavy machinery and intensive labor employment are necessary for the manufacturing process.

Today, we are in an era of extensive automation and aluminum 3D printing service has become the new-edge production procedure. Why not? The evolution of sophisticated 3D printers has eased the process with faster and cheaper production. 

3D-printed aluminum products are extensively used across multiple industries, including medicine, aerospace, automobile, etc. Not only prototypes but end-use parts are also highly implemented. Since aluminum is a metal with incredible mechanical and chemical properties, it is widely used for 3D printing metal service.

In this article, we will throw light on the increasing use of aluminum 3D printing, including its benefits. So, let’s begin.

Popular 3D Printing Technologies for Aluminum

The concept of aluminum 3D printing is not restricted to one particular procedure. There are multiple methods to 3D print aluminum. These are:

1. Powder Bed Fusion (PBF)- It is the top 3D printing technology, which includes selective laser sintering (SLS), selective laser melting (SLM), and direct metal laser sintering (DMLS). The process uses the sintering of layers of fine aluminum powder by a laser or electron beam.
2. Metal Filament Extrusion- It comprises fused deposition modeling (FDM) and fused filament fabrication (FFF). In this process, the metal filament is heated and extruded through a nozzle on the build platform. Then, the part is placed in a furnace to burn out the plastic and sinter the metal.  
3. Binder Jetting- It is pretty similar to PBF, except the metal particles are bonded by an adhesive.

Why Choose Aluminum 3D Printing?

Aluminum is a widely used metal possessing impressive product manufacturing qualities. However, if we are to say why you should choose an aluminum 3D printing service, then here are the reasons:

• Design Flexibility- Compared to traditional manufacturing techniques, 3D printing offers enormous flexibility in design. You can create intricate parts with design complexities effortlessly.
• Low Manufacturing Cost- Today, 3D printing is a cost-effective additive manufacturing process. It does not require additional tooling or intensive labor employment.
• Faster Production- The production process is much faster since the lead time is less. It means the delivery of products is prompt.
• Enhanced Performance- 3D printed aluminum parts possess improved mechanical properties, enabling extensive utilization across a vast sector.
• Sustainable Production- The waste production in 3D printing is much reduced compared to the conventional methods. Since the ecological footprint is low, it curtails environmental impact.

Therefore, 3D metal printing aluminum is undoubtedly an expedient manufacturing process that is here to rule in the coming times.
