I’ve reviewed a couple of consumer 3D printers from ELEGOO so far…the Mars Pro MSLA printer , and the Neptune 2 FDM printer . Now I’m taking a look at the Mars’ big brother, the ELEGOO Saturn MSLA printer. SLA vs FDM:

The Two Types of 3D Printing

 .

Briefly, for our readers who aren’t that familiar with 3D printers but are thinking about dipping their toes in the water: There are essentially two types of printers available, stereolithographic (SLA) and fused deposition modeling (FDM). FDM models use a heated filament (most frequently PLA plastic) to build up a model, adding layer after layer until the model is complete. SLA printers use light to solidify a layer of resin at a time, creating the model. In the case of the Mars Pro, which is a masked stereolithographic (MSLA) printer, it uses light specifically from an LED array combined with an LCD photomask. Both types of printers use their own type of “slicer” software to prepare a 3D model for printing, allowing you to adjust for the type of material you’re printing, how much detail you want to put into the final product (the finer detail, the longer it takes to […]
