What is 3D Printing?
Did you know that 3D printing has been around for quite some time now and has come a long way since its inception? It’s amazing how much it has advanced! Nowadays, there are various types of 3D printing technologies available, each with its own set of advantages and disadvantages.
You’ll find that these technologies are widely used in different industries such as healthcare, architecture, engineering, and manufacturing, or even for hobbyists. So what are some of these technologies? Let’s mention a few and help ‘print’ a clearer picture (pun intended).
Digital Light Processing (DLP)
DLP, or Digital Light Processing, is a 3D printing technology that uses photopolymerization to solidify liquid resin into a solid object. Unlike SLA, another resin-based 3D printing technology that uses a laser, DLP uses a projector to shine light onto the resin, solidifying it layer by layer. This allows DLP to produce parts up to ten times faster than SLA, making it a more efficient option.
Despite being more expensive than FDM printers, DLP printers are still more affordable than SLA printers. This affordability, combined with the fast production rate, makes DLP a popular choice in product design, engineering small parts, and hobbyists alike.
The high precision and accuracy of DLP printers also make them ideal for creating intricate designs and fine details. Additionally, DLP can produce parts with smooth surfaces and sharp edges, perfect for creating detailed and complex geometries.
DLP technology may be more expensive than FDM printers, but its speed, precision, and longevity in projector quality make it an invaluable tool in various industries, including product design, engineering, and dental and jewelry applications.
Stereolithography (SLA)
The twin sibling to DLP is called SLA, which stands for Stereolithography. It is a highly popular form of resin-based 3D printing that uses a laser to cure liquid resin into solid parts. This intricate technology is renowned for producing parts with exceptional detail such as miniatures, product design, engineering small pieces, and hobbyists.
While SLA printing may seem complex, the superior quality of the finished product makes it a wise investment for those interested in spending more for a high-quality finished product. Just know that your 3D printer may need parts replaced more frequently than a DLP printer.
Fused Deposition Modeling (FDM)
So you want to get into 3D printing, and don’t want to break the bank? Let me tell you about Fused Deposition Modeling (FDM). It’s a pretty popular 3D printing technology that’s known for being affordable, easy to use, and versatile. You can create all kinds of 3D objects by melting and extruding thermoplastic filaments layer by layer.
And the best part? Even though it’s cheaper, FDM still produces impressive results! So if you’re on a budget, this might be the perfect option for you. Plus, it’s so easy to use that even if you’re new to 3D printing, you’ll be able to get the hang of it in no time.
Seriously, if you want to give 3D printing a try, you should definitely consider FDM. It might not be as high-quality as some other technologies, but it’s still a great way to explore the world of 3D printing and create your own unique objects. So why not give it a shot and see what you can come up with?
Selective Laser Sintering (SLS)
Got some serious cash laying around? There’s this 3D printing technology called Selective Laser Sintering (SLS) that’s super advanced and innovative. It fuses powdered material together using a laser to make a 3D object that looks awesome and works great too.
The reason SLS is so cool is that it can make super complicated shapes and designs that would be near impossible with regular manufacturing methods. Plus, SLS can make parts that actually work and are super tough and reliable, so it’s great for all kinds of things engineering or miniature related.
However, it is worth noting that SLS printers can be more expensive than other types of 3D printers and require specialized training to operate effectively. Additionally, the process of sintering powdered material can generate a significant amount of heat, which can cause warping or distortion in the final product if not properly controlled.
And get this, SLS is so precise and accurate that it’s a top choice for manufacturers who want to make parts that are top-notch and meet all the highest standards for quality and performance. Pretty sweet, right? Well, if you can fork over several thousands of dollars and not blink an eye, then this is for you!
Summary
As you can tell, the world of 3D printing is quite vast and varied, with lots of different technologies available to you today. Each type of 3D printing technology has its own unique advantages and disadvantages. For instance, some are better suited for creating small, intricate objects, while others are better for larger, more complex designs.
It’s important to understand the key differences between these technologies so that you can choose the best option for your specific needs and budget. This way, you can ensure that you have access to the right tools to bring your ideas to life.
For example, if you’re a hobbyist, you might be interested in a more affordable 3D printing technology that’s great for creating smaller objects with high precision. On the other hand, if you’re a professional, you may require a more advanced 3D printing technology that’s capable of handling larger, more complex designs.

Out of all these fancy techs, we think DLP is the best bang for your buck. It’s pretty cheap and it makes stuff super fast compared to other resin-based 3D printing techs like SLA. But don’t just take our word for it – make sure you understand all the differences between these techs and choose the one that’s best for your needs and budget.
No matter what your needs are, there is a 3D printing technology out there that can help you achieve your goals. With so many options available, it’s important to take the time to explore your options and find the technology that is right for you. So go ahead and do your research, and don’t be afraid to experiment with different technologies until you find the one that fits your needs best!
