Even the best artists in the world struggle to show us what virtual, real-world objects look like in their three-dimensional (3D) glory. Most of the time, it doesn’t even matter to us – for instance, looking at a perfectly drawn picture gives us a rough idea of the product’s final look. But, if you are a part of a business launching machinery parts or any sort of other physical objects, then you might want to see the product’s 3D design before practically launching the product. Or in other words, before coming up with its sample. Well, in this case, nothing beats a prototype – it allows you to touch, hold, and feel the object in your hands in its initial stages.
Thankfully, we have 3D printers these days that allow developers to build 3D models at much cheaper rates than traditional methods. But, have you ever wondered, how do 3D printers work, and what’s the mechanism behind it? Well, let’s find out.
3D printing relies on a computer-aided design (CAD) to build three-dimensional objects through a multi-layering method. 3D printing, also known as additive manufacturing, involves layering different materials, like composite, plastics, or bio-materials to create physical objects that vary in size, shape,rigidity, color, etc.
How Does A 3D Printer Work?
3D printers work just like inkjet printers, but in virtual/physical formats. They work by building up a 3D model layer-by-layer from the bottom upwards, and constantly printing over the same areas – this repetitive layering method is known as fused depositional modeling (FDM).
The 3D printer is fully automatic – so, it operates on its own. It is powerful enough to create various models for consecutive hours by turning its 3D CAD drawing into tons ofcross-sectional, two-dimensional layers. During the process, it effectively separates 2D prints that are sitting on the top surface, without having any paper in between.
The major difference is that 3D printers rely on molten plastic, or powder instead of ink to come up with the final product. The machine fuses the mixture together with the help of ultraviolet light or adhesive. 3D printers can also be considered as a part of the additive manufacturing chain, as it uses similar printing methods to traditional inkjet printers – albeit in 3D formats. It uses a combo of high-end software systems, precision tools, and powder-like material to build three-dimensional objects from scratch.
Interestingly, we have a wide range of 3D printers on the market that have various internet-enabled features as well. For example, connecting your 3D printer to a stableinternet can allow the users to print remotely, through various online interfaces. In simpler words, you can open up your web browser and control your 3D printer from there.

3D Modeling Software
3D modeling is the first step of the 3D printing process. To maximize precision, all objects need to be designed in 3D modeling software. However, some designs are too complicated and intricate to go through the traditional printing methods only – and that’s where CAD software comes to the rescue.
The modeling process allows the printers to produce customized products as per their liking. Up until now, 3D modeling has been a top hit in the market for its high-processing abilities to approve customized precision designs – it has proven to be a game-changer for many industries. For example, 3D modeling software is specifically helpful for dentistry where laboratories are successfully coming up with three-dimensional software for teeth aligners. It allows them to produce much better quality for their clients, in terms of measurements and shape. Also, the dental technicians are able to spot any glitches in the product during the initial stages only, before handing over the final product to their customers.
Slicing the 3D Models
Once the 3D model has created the final product, it’s time for the slicing. As 3D printers cannot process the concept of 3 dimensions like humans, the engineers and technicians need to slice the model themselves into layers.
The 3D slicing software works by taking scans of different layers of a model and indicating to the printer how to move in order to produce the perfect layers. These slicers also send signals to the printer to indicate where to fill a model – this fill is supposed to provide the 3D product an internal lattice and column to shape and strengthen itself. So, once your 3D model has been sliced, it is sent to the printer to carry out the actual printing procedure.
The Bottom-line
We hope you enjoyed learning about the functioning and features of 3D printers.Although we have tried to cover up all the important aspects of 3D printing in this article, still if you wish to know more about its processing, please reach out to some reliable tech-related websites, blogs, or articles on the internet.
