3D Printing

Printing is a process that most of the people are already familiar with. We just make use of a printer, and get stuff printed in 2 dimensions on the paper. But did you ever imagine the concept of 3D printing? Well, it’s not just a concept, but a reality now, with many of the products and objects being built through 3D printing, instead of traditional manufacturing processes.

In this article, we are going to talk about 3D printing. We will explore what is 3D printing, how it works, and the software, and also we will talk about some applications of 3D printing. So, let’s dive into the world of 3D printing!

What is 3D printing?

Well, most of you might be already familiar with the good old concept of printing, which we have been practicing for years, from printing information to designs to even house blueprints. But when it comes to 3D printing, it is something that is revolutionary has a number of applications, and is growing.

3D printing can be understood as a process, in which a digital file is used for creating a 3 – Dimensional Solid Object. In this 3D printing process, sequential layers of material are laid down by the 3D printer, until the object creation is done. The 3D printing is also called as Additive Manufacturing. Later on, we will understand how 3D printing is done in greater detail.

3D printing is not just a concept, but a reality now, being used in many places, in order to print many objects, things, and even houses, and buildings. I am not joking, if you want you can explore the houses and the buildings being manufactured with 3D printing. Many startups and companies have been using this technology.

How does 3D printing work?

Now, some of you might be wondering how does this 3D printing work? Well, we will not go into much technicalities of the technology, but let’s understand it in layman’s terms.

3D printing is also called additive manufacturing, and in simple words, you can understand this as if the 3D printer places layer after layer of the material until the desired object or thing is “Printed”. Each layer printed by the printed can be considered as a finely sliced cross-section of the thing being “Printed”.

3D printing enables consumers to be able to produce complex shapes and structures without consuming much material in comparison to traditional manufacturing methods.

Here, we are NOT cutting out any material using the machinery, which happens in subtractive manufacturing. Instead, in additive manufacturing, the layers of the material are stacked and fused. There can be many different advantages of 3D printing from different angles, about which we will try to talk later.

Please understand that the above explanation is in layman’s terms, and there are some different types of 3D printing processes, and each works quite differently. Later on, you can explore and dive deeper into the concept, if you are interested in this.

Types of 3D printing

Diving deep into the world of 3D printing, let’s try to understand about some different types of 3D printing processes and techniques. First of all, let’s list out the different types, and then we will explore each type one by one, in quite greater detail.

  • VAT Photopolymerization.
  • Binder Jetting.
  • Powder Bed Fusion.
  • Material Extrusion.
  • Direct Energy Deposition.
  • Sheet Lamination.
  • Material Jetting.

Now that we have listed some of the types of 3D printing processes, let’s have a brief look at them one by one –

VAT Photopolymerization

In simple words, we can understand this process as a process, where photopolymer resin is exposed to certain wavelengths of light and then it becomes solid. The additive manufacturing processes like Stereolithography(SLA), Direct Light Processing, and Continuous Direct Light Processing come under the category of VAT Photopolymerization.

In Stereolithography, the object being printed is created by selectively curing a polymer resin layer by layer, using an Ultra Violet laser beam, making it a hardened plastic.

Digital Light Processing is somewhat similar to SLA but uses a digital light projector screen to flash a single image of each layer at once.
Continuous Digital Light Processing is very similar to DLP, but it is dependent on the upward motion of the build plate.

Overall, the VAT photopolymerization process is a great choice for most of the jewelry and medical applications, due to the fine details and smooth finishing done.

Binder Jetting

Like many other 3D printing technologies, Binder Jetting doesn’t require heat. Binder Jetting can be considered as an additive manufacturing process, in which, an industrial printhead selectively deposits a binding adhesive agent into the thin material layers.

Powder Bed Fusion

Powder Bed Fusion(PBF) technology uses a heat source to bring fusion between the particles of plastic or metal powder one layer at a time. The processes like Selective Layer Sintering(SLS), Multi Jet Fusion(MJF), and Electron Beam Melting(EBM) all come under this category. Even the 3D metal printing processes like Selective Laser Melting, and Direct Metal Laser Sintering(DMLS) also use the Powder Bed Fusion for selectively binding the metal particles.
Material Extrusion

The material Extrusion process is very simple and straightforward to understand. The Material Extrusion technique can be simply understood as a process, in which the material is squeezed through a nozzle onto the build plate layer after layer. Fused Deposition Modeling(FDM) falls under this category, and it is one of the most widely used technologies in the world of 3D printing.

Direct Energy Deposition

Direct Energy Deposition, or DED, is a 3D printing method, in which, a focused energy source, like a Plasma Arc, laser, or electron beam is used to melt the material being simultaneously deposited by the nozzle.

The Laser Engineered Net Shape (LENS) and Electron Beam Additive Manufacture(EBAM) fall under this category.

Sheet Lamination

Sheet Lamination can be simply understood as an Additive manufacturing Methodology, where the thin sheets of material are bonded together layer by layer, in order to form a single piece that is cut into a 3D object. There are some different types of laminations to choose from, like bonding, ultrasonic welding, or brazing.

Material Jetting

The Material Jetting technology uses ultraviolet (UV) light or heat to harden the metals, photopolymers, or wax, building the parts one layer at a time. Other types of Material Jetting include NanoParticle Jetting and Drop On Demand.

Best 3D Printing Software

The world of 3D printing is more dense than it appears. It is highly dependent on Software in many phases, from designing the output to controlling the 3D printer. So, another obvious thing that you might want to know is the best software you can use for 3D printing. There are many options for Software related to 3D printing, but we will talk about some software here.

So, let’s check out some of the best 3D printing Software. Please note that the order in which the software is arranged does not define their ranking.
