Understanding 3D Printing Technology

What is 3D Printing?

3D printing, sometimes known as additive manufacturing, is a process where a three-dimensional object is created by laying down many continuous layers of material until the final product is formed.

In other words, 3D printing is like having a magical machine that can turn any design you can think of into physical reality. From a simple toy to a complex engineering component, you can make it out of thin air with just a few clicks.

The future possibilities of this technology are almost limitless! It’s changing the way we think about manufacturing, design, and even creativity itself.

Evolution of 3D printing: Key milestones of 3D printing

The evolution of 3D printers has been a remarkable journey since the inception of the idea several decades ago. From its humble beginnings to its current advanced stage, here are some key milestones that have shaped the technology into what it is today.

• 1981: Dr. Hideo Kodama created one of the earliest rapid prototyping machines that built items layer by layer. He used a material that could be polymerized by UV light.
• 1984: Stereolithography, the first 3D printing method, was created by Charles Hull. It which used a laser to cure a liquid photopolymer into solid layers.
• 1992: Hull received the first 3D printing patent. This opened the door for industrial 3D printing.
• Late 1990s: Thermoplastic filaments were extruded layer by layer to construct a 3D object using fused deposition modelling (FDM) technology.
• 2000s: Selective laser sintering (SLS) and direct metal laser sintering (DMLS) technologies were developed. These made it possible to accurately create complicated metal pieces.
• 2010s: Desktop 3D printers became affordable and widely available. So homes and small businesses could also enjoy it’s benefits. New materials such biodegradable polymers, ceramics, and metals were created for 3D printing.

How Does 3D Printing Work?

3D printing works on the concept of Additive Manufacturing. This basically means depositing material like plastic or metal layer by layer. It follows instructions from a digital model or blueprint in a way that creates the desired shape. As each layer is added, it fuses with the previous layer, creating a solid object.

How 3D Printing Works in More Detail:

The process begins with a 3D digital model. This is created using 3D modelling software. You can also get them from 3D scanners that scan physical objects and convert them into digital models like a blueprint.

Then the 3D printer reads the digital file of the object and slices the model into thousands of thin layers. These are then created using different methods, depending on the technology used by the printer. Some 3D printers use melted plastic, metal, or resin. Others use powder or liquid that is solidified using lasers or UV light.

Once the 3D printer has created the first layer, it moves on to the next layer. It adds another layer of material, sticking it to the previous layer. This process continues until the entire object is created. The printer can also sometimes need support structures to hold the object in place during printing, which is later removed.

Types of 3D printing Technology

There are 8 major types of 3D printing technology that include: Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Digital Light Processing (DLP), Binder Jetting, Material Jetting, Direct Energy Deposition (DED) and Electron Beam Melting (EBM).

• Fused Deposition Modeling (FDM) uses melted plastic filament to create objects layer by layer.

• Stereolithography (SLA) uses a liquid resin that is cured with UV light to create solid objects.

• Selective Laser Sintering (SLS) uses a laser to melt and fuse together powdered material, such as metal, plastic, or ceramic.

• Digital Light Processing (DLP) uses a liquid resin similar to SLA, but it uses a digital projector to cure and create the final object.

• Binder Jetting uses a liquid binder to fuse together powder materials, such as sandstone or metal.

• Material Jetting uses a print head to deposit droplets of material, layer by layer, to create an object.

• Direct Energy Deposition (DED uses a high-energy heat source to melt and deposit material and is often used in metal printing.

• Electron Beam Melting (EBM) uses an electron beam to melt and fuse together metal powder to create solid metal objects and It is similar to SLS, but uses an electron beam instead of a laser.

Types of 3D printing Materials

There are many different types of 3D printing material and can be categorized as:

• Plastics (PLA, ABS, PETG, Nylon)
• Metals (Stainless Steel, Titanium, Aluminum, Copper)
• Resins (Standard, Flexible, Tough, Castable)
• Ceramics (Porcelain, Stoneware, Earthenware)
• Wood-based (Bamboo, Birch, Maple, Cherry)
• Composites (Carbon Fiber, Fiberglass)
• Paper-based (Cardboard, Copy Paper)
• Food-based (Chocolate, Dough, Sugar)
• Bio-based (Living Cells, Living Tissue)
