Difference Between FDM and Resin Printer

The world has seen tremendous technological advancements. One of the latest and most awesome inventions is the use of 3D printing, which utilizes multiple technologies such as Fused Deposition Modeling (FDM) and digital light processing (DLP). FDM is a type of 3D printing in which the material is layered in builds up to the desired shape, while DLP printing is used to speed up the printing process by using liquid plastic and photopolymers to rapidly create parts. In this article, we will discuss the differences between FDM and DLP technology and shed some light on which type of 3D printing is more suitable for your specific needs.

Fused Deposition Modeling (FDM)

FDM is one of the most popular and oldest 3D printing technologies. It is capable of producing highly accurate parts, making it ideal for a wide range of applications including medical, prototyping and production. This technology works by depositing a thin filament, called the model material, into the desired shape. The model material then hardens and is removed from the printing bed. The printing speed, resolution, and accuracy of the printed parts depend on the parameters used in FDM.

Digital Light Processing (DLP)

DLP is an advanced 3D printing technology that utilizes light to rapidly create parts with higher accuracy and better surface finishes. This technology requires the use of a photopolymer resin, which is cured using a light source such as a projector. The resin is exposed to the light to quickly turn it into a solid object. As a result, the printing speed is much higher than that of FDM technologies but with a slight reduction in accuracy.

Which Technology is Right for You?

The type of 3D printing technology that is right for you will depend on the specific application. FDM technology is more suitable for applications that require a higher resolution, greater accuracy, and the ability to build complex shapes. DLP technology is ideal for applications that need higher printing speeds and better surface finishes. DLP printing is also preferable for medical and production applications due to its high levels of accuracy.

Summary

To summarize, FDM and DLP are two of the most popular 3D printing technologies available today. FDM offers a higher resolution and accuracy, while DLP offers higher printing speeds and better surface finishes. When choosing the right technology for your application, it is important to assess the needs and find the technology that best suits your needs.
