I don't model for printing my self my my understanding is that the printer/filament has a specific resolution that dictates a minimum feature size - going below this size will cause the features to flow together.
cg cookie did a tutorial on it a while ago;

Right now you are limited by the maximum resolution that your friend's printer can print (likely .1mm).
Think of it like you take a 14 megapixal picture of a tree, and then print the picture on a paper printer that can only print at 100dpi. You will still see a tree, but most of the detail will not be there.
The faces/verts/polys does affect the quality of the print, but only until you hit the max quality the printer can print. In Blender, I usually decimate (in the "add modifier" tab) down to about 50,000 faces. I have down this from as high as about 8 million faces with no perceivable loss in quality of the print.
BTW, that is an awesome elemental tile you have there.

Actually, the more I look at the photo, the more I think your friend may have printed it at a resolution of .2mm. Ask them to print it again at .1mm. I bet you will regain a bunch on the missing detail....

He did give me the advice I should exaggerate the details so they might show better. Will try that next time. Oh so around 50,000 faces is the magic number lol? I had over a million and brought it down to 300,000, but can bring it down more, no problem.

I use about 50,000 faces just because there doesn't seem to be any point to having a 150mg file when you can print the same quality with a 3mg file. Also, many sites and service software (like NetFabb) have a 100mg file cap. And Blender for me starts getting really really slow when the poly count starts getting up there.
Your friend has good advise: Exaggerate the detail. Take a look at the gap between the square floor bricks (the grid lines). Im going to guess that the gap in the file measures somewhere between .5mm and .75mm. That barely shows up as a pronounced gap. Use that as a base reference for the rest the things you design.

I finished some tiles, but when I bring them into netfabb it gives me errors. I checked them in Blender and it says there's no problem, but netfabb brings up errors. I tried fixing them, but some seem to not work. One of the tiles disappears when I try the automatic repair. First time using the program. Anyone who knows what they're doing, could you take a look at them? Here are some of the files.

I ran one of the 2x2 A tiles through NetFabb and it cleaned up almost all of the self-intersecting surfaces. The two that it didn't fix I wouldn't worry about.
Two things to consider: When I dropped the file into the slicing software, it said that the tile size was 1.6mm x 1.6mm. (Blender confirmed the scale was to small to see the tile). I imagine that the hollowed out underside of the tile is for some form of locking clip? You may run into problems printing it successfully. The way it is designed leaves very little contact to the build plate when you try to print it. The printer may also have trouble bridging the top of the cavities. Just two cents.

Yeah the one floor tile runs ok, I think I could understand that one. But I think it is the wall tile that disappears when you try to repair it. Do you know why that happens? Yeah I knew the file was too small. I built it with inches in mind, but didn't care to change it over to mm. I'll do that when I'm 100% they're ready. Yes it is designed for clips. I've been thinking about just filling in most of the bottom anyways, so I might just do that. I have someone doing a test print this weekend to see how it looks Will post the pics then. Your 2 cents is a welcome lol.

I've brushed on some slightly thinned modeling past on 3D printed dungeon tiles in the past, filling in the print lines I didn't like. Seemed to improve the appearance of the particular tile quite a bit.
Also if the tile you print has enough varying/random texture, the less any "print lines" will show up. I notice.

Yeah I did notice that too. I was looking at some pics of of models next to the stl file and it seems more detail helps hide some of those lines.

2 things, Should I start a new thread with my designs or keep this one? next, here are a few things I've been working on, but not everything. Gate Floor Spiral Stairs with Door Down Long Narrow Passage Collapsed Narrow Passage Stairs Down Hidden Door Wall Double Doors

All walls that does not support a door, window, secret passage, torch, etc I would lower to be only 1-2 cm high else your going to have problem manipulating the minis in there or even seeing them.
Other than that they look fine - I especially like the winding stair / door combo

Other than that they look fine - I especially like the winding stair / door combo 1-2 cm would be way to short for my plans. But I will make short walls for most of these. A few I might have to remake. But most I have planned to turn into short versions too.
