An In-Depth Look At The Different Types Of 3D Printing Technologies Available Today

In the last few years, 3D printing technology has become increasingly popular as more and more people are turning to this high-tech method of creating objects. But what many don’t know is that there are a variety of different types of 3D printing technologies available today, each of which has its unique advantages and disadvantages. In this article, we look in-depth at the different types of 3D printing technologies available today!

Introduction to 3D Printing

3D printing is creating a physical object from a 3D computer model of that object. There are currently many different types of 3D printers on the market because 3D printing technology has advanced significantly in recent years. Each type of 3D printer has its unique capabilities and benefits, and choosing the right type of printer for your specific needs is essential to getting the most out of this technology. The first thing to consider when choosing a 3D printer is what material you want to print with. The most common materials used in 3D printing are plastics, metals, and ceramics. Each material has its own unique set of properties that will affect the final product, hence it is important to choose a material that is compatible with the type of object you want to create. Once you've decided on a material, you need to choose a printing technology that is compatible with that material.

Types of 3D Printing

There are several different types of 3D printing technology available today.

• Fused Deposition Modeling (FDM)
• Selective Laser Sintering (SLS) 
• Stereolithography (SLA)
• Digital Light Processing (DLP)
• Laminated Object Manufacturing (LOM)

Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM) is a type of 3D printing technology that uses a filament of thermoplastic material. The filament is fed through a heated extrusion nozzle, which melts the material and deposits it in layers, on a heated bed in an enclosed chamber maintained at the desired temperature, to build up the desired object. 

Advantages 

• It is a relatively low cost
• It is easy to use.
• It is well-suited for prototyping and small-scale manufacturing applications.
• Products printed with this method are industrial-grade
• Produces strong and durable parts

Disadvantages

• It can produce visible layer lines
• It generally has a poorer surface finish

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) is a 3D printing technology that uses a laser to fuse small particles of plastic, metal, ceramic, or glass powder into a three-dimensional (3-D) solid object. The laser selectively fuses the powder particles by melting them. This layer-by-layer approach to 3D printing allows for the creation of complex shapes that would be difficult or impossible to make with traditional manufacturing methods.

Advantages 

• SLS is well-suited for creating prototypes
• It is used for manufacturing small batches of parts 
• Very little  post-processing is required after printing
• It used to print in a wide range of materials, including metals and ceramics

Disadvantages

• It can be expensive
• SLS printers are typically large and bulky

Stereolithography (SLA)

Stereolithography or SLA works by using a laser to cure a photopolymer resin into the desired shape. If you're looking for high-quality parts with tight tolerances and smooth surfaces, stereolithography is likely the best 3D printing technology for your needs.

 Advantages 

• It supports higher resolutions
• It has higher accuracy
• It can produce parts with smooth surface finishes

Disadvantages

• SLA printers are more expensive

Digital Light Processing (DLP)

Digital Light Processing (DLP) is a form of 3D printing technology that uses a digital projector to cure the photo-sensitive resin with ultraviolet light. A DLP projector projects an image onto a build platform, which is then coated with a layer of liquid resin. The light from the projector cures the resin, and the process is repeated until the desired object is built up layer by layer.

Advantages 

• DLP printers are fast
• It produces high-quality results

Disadvantages

• DLP printers are more expensive than both FDM and SLA printers
• It requires specialized resins

Laminated Object Manufacturing (LOM)

Laminated Object Manufacturing is a type of 3D printing technology that uses layers of material to create an object. The process begins by creating a digital model of the object to be printed. This model is then sliced into thin layers, and each layer is printed one at a time. The layers are then bonded together to create the final object.

Advantages 

• It produces objects that are strong and lightweight
• It is used for producing medical implants 
• It is used for producing aircraft parts. It can also be used to create objects with complex shapes.

Disadvantages

• It is relatively slow compared to other 3D printing technologies
• It can also be difficult to achieve fine details with this method
