What is the difference between PLA and SLA 3D printing?

Mar. 31, 2022

There is no doubt that 3D printing is a common technology in engineering and manufacturing today. While 3D printing is most commonly used to create working prototypes or 3D models that an investor can hold in his hand, it can also be used to create durable moving parts for your product, provided it's guaranteed. Here's what you need to know about the different types of 3D printing and when to use them.


The development of SLA and SLS dates back to the early 1980s. This was followed by the release of the first commercial SLA system by 3D Systems in 1986. In the early 1990s, DTM commercialized the first SLS Systems, which later became part of 3D Systems. What's the point of the history class, you ask? Really emphasize how much additive manufacturing has evolved over 20 + years of industry experience. Over the years, we have been in a position where technology and materials have been tried, tested and refined.

So, what's the difference between a SLA and an SLS? There are some things in common, for example, both use lasers to track and build layers. For SLS, the liquid resin is cured, whereas in SLS the powder is selectively fused together. Selective laser sintering (SLS)

Comparing these technologies is not easy because each has its pros and cons. If we limit it to one sentence, SLS are generally stronger and less costly, while SLAS produce parts with tighter dimensional tolerances and better surface finish that are more similar to injection molded parts. However, once we start to look in more detail, the choices start to boil down to the requirements of individual projects.


SLA 3D printing for manufacturing

SLA or stereoscopic photocuring molding 3D printing is an original process developed in the 1980s. SLA uses lasers to solidify liquid resins in hardened layers to build 3D models and even products with moving parts. SLA 3D printers offer durability, functionality, and flexibility to work within the parameters you need.

In manufacturing, SLA 3D printing is often used to create working prototypes before actual manufacturing begins. That's because 3D printing projects that go wrong is cheaper than making products out of expensive materials without perfect products.


PLA 3 d printing

PLA 3D printing is the most popular because it is the cheapest and most widely used. PLA has some advantages over SLA, but not in terms of performance. If you are just making the first prototype or physical model of the project, PLA will be suitable for that purpose. In fact, it is a good idea to use PLA at this stage to keep costs low while our engineers and your team refine the project. After all errors are resolved, the project should be moved to the SLA 3D printer for the next phase of the project.
