A while back, I made a post about the different types of 3D printing. It focused on explaining the differences between filament-based printing (fused filament fabrication, or FFF) and resin-based printing (stereo lithography apparatus, or SLA) and how they go about creating a 3d print. It also linked to an article on All3DP.com that provided more details about FFF, SLA, and many other types of 3d printing.
For this post, I'm once again focusing on filament and resin printing, but this time, I will explain the pros and cons of each in relation to model railroading.
In October of 2020, I procured my first SLA printer. Since then, I've used it to build n scale new models as well printing some older models that had only been printed using filament printer. I have to say that it has been very satisfying because it printed my older models in much higher detail than my filament printers. It is very exciting to have this technology available at my fingertips!
While SLA printing has definetly found a permanent home at Lyforms Small-Scale, filament printing continues to play a big role in creating n scale models. I find that it still works well for larger parts because they come out strong and quickly. I still think that filament printing can print a decent amount of detail for n scale, especially considering that the naked eye is limited to how much detail it can distinguish. Most casual admirers of model railroad layouts won't be able to see details that are too tiny.
Based on my experience, here is my list of pros and cons of filament vs resin. Again, these are in relation to model railroading.
