3D printers, the future of technology
3D printing has gained momentum and popularity in recent years. The concept of a machine capable of turning whatever you design from your computer into a reality has attracted a lot of attention, but if you want to know how they work and a little more about them, this article is for you.
3D printers allow you to create a 3-dimensional object by successively building layers until you achieve the desired object. This process is called "additive processing." Currently, there are also 3D scanners that can scan an object and view it directly on our computer for later printing.
Types of 3D printers
Polymer deposition (FDM): Polymers are plastics. So, what it does is melt a polymer filament through a spout and deposit layer upon layer of the molten material until the solid object is created. The material itself is then added in layers until the desired shape is created. This technique is also known as "Fused Material Deposition" or FDM.
These printers are generally less expensive and are the most commonly used in education. They allow for creating parts using ABS plastic similar to the material used in Lego toys.
They are also through laser and there are two types of these:
SLA or photosolidification:
A polymer hardens in light. It starts with a base that's submerged in a container filled with liquid resin, and the resin flows out layer by layer. The laser then solidifies the base as it flows out of the container, creating the object. This process is called stereolithography.
SLS: Laser sintering of a material:
The material, unlike SLA, is in a powder state. The laser hits the powder, melting it and solidifying it. It's the same as SLA, except the material in which the base is coated is powder.
A wide variety of objects can be 3D printed. Whether it's household items, models, food, space components, prosthetics, human organs, etc. Let's say anything you can "create" yourself could be printed in 3D.
And while you might think these printers are designed for small objects, there are large printers that can even print a building piece by piece, including its furniture.
An example of the development of this technology is being applied by NASA itself, which will send one of these 3D printers to the International Space Station so astronauts can manufacture parts they deem necessary in space.
If you're interested in purchasing a printer, we have a catalog of printers with different prices, sizes, and features, as well as filaments in various colors so you can make your creations a reality.
