In terms of maintenance needs, which technology is typically less demanding?

Fused Deposition Modeling (FDM) technology is generally viewed as less demanding in terms of maintenance compared to Stereolithography (SLA). One reason for this is that FDM relies on thermoplastic filaments that are typically easier to handle and less sensitive to environmental conditions than the resins used in SLA.

With FDM printers, maintenance primarily involves tasks such as cleaning the nozzle, checking the extruder, and occasionally replacing parts like the build surface. These tasks are usually straightforward and can often be performed without specialized training. Additionally, FDM machines tend to have fewer critical components that require frequent calibration or replacement.

On the other hand, SLA printers involve a more complex setup that includes resin management, UV light systems, and often delicate components like build platforms and vat mechanics. The resins used in SLA can be more messy and hazardous, requiring more careful handling and cleaning, which adds to the maintenance workload.

Overall, due to its simpler operation and fewer maintenance requirements, FDM technology is suited for users looking for a less demanding maintenance experience.
