Introduction

The rise of 3D printing in Chennai is a testament to the city’s growing technological prowess. Once considered a futuristic concept, 3D printing is now revolutionizing various industries across Chennai. But why has Chennai become a hotspot for this innovative technology?

History of 3D Printing in chennai

Evolution Over the Decades

Since its inception, 3D printing has evolved significantly. Initially used for simple plastic prototypes, it now caters to complex metal parts and is widely adopted in sectors such as healthcare and aerospace. This evolution has made 3D printing more accessible and versatile.

Understanding 3D Printing Technology

How 3D Printing Works

At its core, 3D printing involves creating a three-dimensional object by layering materials based on a digital design. Starting with a 3D model created using CAD software, the printer reads the design and layers material until the object is complete.

Different Types of 3D Printing Technologies

• Stereolithography (SLA): Uses UV light to cure layers of photopolymer resin.
• Selective Laser Sintering (SLS): Fuses powdered material using a laser.
• Fused Deposition Modeling (FDM): Extrudes melted thermoplastic to build objects layer by layer.
• Direct Metal Laser Sintering (DMLS): Similar to SLS but for metal powders.
• Multijet Fusion (MJF): For high quality production grade plastic parts
