3D printing has become a popular buzzword in recent years. Whether you are an architect who wants to print a mock-up of your design or a person who wants to print a customized piece of jewelry, 3D printing has allowed us to do things that were previously impossible. But have you ever wondered how exactly this technology works? In this blog, we will dive deep into the basics of 3D printing and explore the process behind it.
The process of 3D printing.
The process of 3D printing involves the creation of a physical object from a digital 3D model. This model is created using a 3D scanner or a computer-aided design (CAD) software. The 3D model is then loaded into a 3D printer.
The 3D printer starts by slicing the 3D model into thousands of horizontal layers, each of which is thin enough that it can be printed individually. Then, the printer creates the object layer by layer.
There are various types of 3D printing technologies, but the two most common ones are fused deposition modeling (FDM) and stereolithography (SLA). Let's take a closer look at how both these methods work.
Fused deposition modeling (FDM).
FDM is a widely used 3D printing technology. In this method, the printer uses a spool of thermoplastic filament, which is melted and extruded through a nozzle onto a build plate. The build plate moves down with each layer, and the printer continues to add layers on top of each other until the object is complete.
One of the most significant advantages of FDM is its versatility. Different types of filaments can be used, such as nylon, ABS, and PLA, to create objects with different characteristics like flexibility, strength, and heat resistance.
Stereolithography (SLA).
SLA is another 3D printing technology that utilizes a liquid resin material. In this process, the resin is exposed to an ultraviolet (UV) laser beam that hardens it layer by layer. The laser beam traces the 3D model, solidifying the resin where it is exposed to the laser light.
The build tray moves down with each layer, and the printer continues the process until the object is complete. Once finished, the object is rinsed with a solvent to remove any excess resin and cured under UV light.
SLA is useful for creating intricate and detailed objects. It is commonly used in industries such as healthcare and dentistry for creating accurate and customized models.
Conclusion.
3D printing technology has come a long way in recent years, and today, it has become more accessible than ever before. With the ability to create an object from a digital 3D model, 3D printing has revolutionized the way we design and create objects. The process of 3D printing involves slicing a 3D model into thousands of layers and building the object layer by layer.
The two most common types of 3D printing technologies are fused deposition modeling (FDM) and stereolithography (SLA). FDM uses a spool of thermoplastic filament to create objects layer by layer, while SLA uses a liquid resin material solidified by an ultraviolet (UV) laser beam.
With advancements in technology and decreasing costs, we can only expect 3D printing to become more common and accessible in the future. From creating complex medical models to printing simple household objects, 3D printing has an incredible potential to change the world as we know it.
