FDM vs SLA: Complete 3D Printing Technology Guide
FDM (Fused Deposition Modeling) and SLA (Stereolithography) are two of the most common 3D printing technologies, each designed for a particular use. FDM employs thermoplastic filaments and is both cost-effective, robust, and simple to operate, and hence appropriate for prototyping and functional parts. SLA, on the other hand, employs liquid resin and UV light to create highly detailed prints with smooth surfaces, hence ideal for detailed designs, dental models, and visual models. Although FDM is cheaper and more suitable for mechanical durability, SLA is superior in precision and finish. The correct option relies on whether your project values strength and price (FDM) or detail and surface quality (SLA).
