In terms of speed and cost, how does FDM compare to SLA?

Fused Deposition Modeling (FDM) is typically known for its advantages in speed and cost-effectiveness when compared to Stereolithography (SLA). FDM uses thermoplastic filaments, which are relatively inexpensive and readily available, leading to lower operational costs. The materials and equipment used in FDM also contribute to faster production times, as the printing process involves melting plastic and extruding it layer by layer, which can be completed more quickly than the curing process in SLA that relies on ultraviolet light to solidify resin.

FDM's ability to print larger parts more quickly also supports its positioning as a faster technology, especially for prototyping and functional parts. It is chosen frequently for applications that require quick turnaround times and lower costs, which is why FDM stands out as being faster and cheaper when compared to SLA, particularly for larger quantities and less detailed prints. In contrast, SLA offers higher resolution and better surface finish, but this comes at a higher cost and generally slower print times, making FDM the preferred choice in many cost-sensitive and time-sensitive applications.
