The technology of 3D printing has emerged and has revolutionized the manufacturing, food, fashion, and healthcare production. Whether a tech scientist, a hobbyist, or even just curious about the newest advancements, 3D printing is something that everyone should be aware of.

In this blog, we will be covering the whereabouts of 3D printing, its operational activity, and what is in store for the upcoming future regarding this path-breaking technology!

Turning Digital Dreams into Reality with 3D Printing

What is 3D Printing?

Digitalization and advancements are at their peak, and one can only imagine being able to design something on personal computer systems at one time, and then holding it in their hands- no requirement of massive machinery and factories, it is just you and a machine that develops objects layer by layer. This is the power that 3D printing withholds, which is also referred to as additive manufacturing. In comparison to conventional methods that slice away material, just like sculpting a block from wood, 3D printing operates in a reverse way. Instead of carving out, it keeps on adding material in a precise way as per the need, thereby creating objects from scratch without wasting anything.

How Does 3D Printing Actually Work?

This usually comprises the following three simple, but mind-blowing steps-

1. Designing the model: It all begins with a digital blueprint! Utilizing CAD software, such as Fusion 360 or TinkerCAD, or even a 3D scanner, one can scan and create a 3D model based on the desire to print. This can be a miniature statue of a pet or even a replacement gear.
2. Slicing the model: The 3D printer does not understand the model as a whole; instead, it needs instructions. In this regard, specialized software, including PrusaSlicer and Cura, can be utilized to chop the design into hundreds or even thousands of ultra-layers that are thin and horizontal. This will effectively turn the 3D object into a stack of 2D slice.
3. Printing the object: The real fun begins in this particular step. The printer primarily heats up the selected material, be it metal, resin, flexible TPU, tough ABS, or even PLA plastic. It then deposits on a layer-by-layer basis, by following the sliced design. After this process, slowly and steadily, the object will take the shape as provided.

Therefore, depending on the complexity and size, a print can take minutes or days for a small keychain or a detailed architectural model. But the best part lies in the fact that no two prints are exactly similar. Whether a hobbyist crafting cosplay props or an engineer prototyping the latest invention, 3D printing ensures the power to directly create anything.

The 4 Game-Changing 3D Printing Technologies

It is obsolete to think that all 3D printers are the same! Just like cars range from heavy-duty trucks to compact city runabouts, even different 3D printing technologies also serve numerous purposes. From being a maker crafting prototypes in a garage or an aerospace engineer developing rocket parts, there exists a perfect method of 3D printing for desired requirements. Now, let us dive into the four most revolutionary types of transformation:

Fused Deposition Modeling (FDM) - The People's Printer

Let’s picture a high-technology-based hot glue gun that has been precisely layered by melting plastic. This is what FDM caters to when in action! This particular 3D printing technology is the most widespread and cost-effective technology, which can melt plastic filament, including PETG, ABS, and PLA, through a heated nozzle that can create objects on the basis of layers. Besides, this technology is suitable for beginners, it comprises low-cost operation with existing materials and is appropriate for educational models, DIY projects, and functional prototypes. On the contrary, FDM cannot match with ultra-smooth finishes since multi-material and soluble support printing are the newest upgrades.

Moreover, as stated in the September 2021 China Journal of Aeronautics report, glass fiber (GF) and carbon fiber (CF) strengthen at least 5% of composite filaments, which are fabricated by utilizing a temperature extruder, along with an increased volume fraction, owing to differences in the density. These filaments are then 3D-printed in test samples by further utilizing a home-based and high-temperature FDM printer, with enhanced fiber content for augmented mechanical components.

Stereolithography (SLA) - The Detail Master

These 3D printers work like magic since they comprise a laser beam that dances across a tank of liquid resin, which hardens it into an exquisite solid form with microscopic precision. The result, in turn, leads to smooth details and surfaces. This particular 3D print is readily utilized by jewelry designers who create intricate pieces, dentists who craft picture-perfect aligners and crowns, and last but not least, artists who produce gallery-worthy sculptures. Besides, one appealing fact is that the existence of detailed miniature figurines are created by SLA printing.

Selective Laser Sintering (SLS) - The Industrial Powerhouse

SLS, in general, turns a laser welding powder into solid nylon or metal parts. It utilizes unsintered powder as natural support, in comparison to other printing methods that require support structures. The ultimate objective is to permit incredibly complicated geometries. SLS printing is a game-changer for industries, for example, the aerospace sector that requires components to sustain extreme weather conditions, followed by durable end-use industrial parts, and customized medical prosthetics and implants. Besides, a few airplane cabins currently comprise SLS-based printing components that are strong and light when compared to conventionally manufactured parts.

Digital Light Processing (DLP) - The Speed Demon

DLP operates in a similar way to SLA, but there is a twist! It utilizes a digital light projector instead of a single laser to cure entire layers at once. This results in blazing fast print speeds without the need to sacrifice any details. This printing method readily excels in fast prototyping, especially during severe timelines, dental laboratories producing numerous crowns in a batch, and research institutions requiring rapid iterations. DLP has a promising future since it can print complicated and twisted objects in minutes rather than hours.

Based on the above-mentioned 3D print types, it is essential to choose the perfect match. From FDM’s cost-effectiveness to SLS’s industrial might, each technology caters to exclusive possibilities. All of these methods are gradually continuing to evolve, thereby producing unusual hybrids and advancements that can blur the lines between them. Besides, it is recommended for beginners to commence with FDM to gain insight and eventually explore SLA to print fine details. Therefore, the 3D printing revolution is not underway; it actually exists, and these four technologies are deliberately leading the charge.

How 3D Printing is Reshaping Our World?

There exists a common notion that 3D printing is all about making simple plastic toys! This revolutionary technology is readily breaking such barriers across various industries in every possible way that seems to be science fiction-based. At present, there are five astonishing industries that are being transformed by additive manufacturing.

Healthcare Revolution: Printing Body Parts

The medical sector is undergoing the biggest leap, owing to the presence of antibiotics. Organizations, such as UNYQ, are effectively creating customized prosthetic limbs that perfectly fit patients at a fraction of conventional expenses. In addition, dentists can easily print aligners and crowns in-office while patients wait during appointments. But the real game-changer is bioprinting, through which scientists have magnificently layered live cells to develop fully functional organs and skin grafts.
