In my personal opinion, the brick is one of the most important inventions of mankind, along with fire and the stone knife. Bricks are used to build simple houses, cathedrals or halls. A brick wall can separate neighbors or connect them by a path. Produced by hand or in mass, the brick is used all over the world and if we would look around more, we could discover how many different applications and forms of the brick there are. The brick has disappeared from our perception as an everyday product, but it has a long history behind it. Also among model makers.
Omnes viae Romam ducunt and so there are different methods to create bricks in model making. As a beginner from egg carton, or for more experienced from XPS foam. You can create bricks from old Warhammer sprues or press them into Greenstuff with a roller. Since I am currently working on a model, I wanted to test how bricks could be made with a 3D printer. unfortunately I have not found any suitable models online. There are complete walls or dungeon tiles, but a single brick was unfortunately not there. Therefore, I have created myself one.
After some tests I decided to use a standard dimension and since I as a European always convert everything into a standard, I invented the ESMB PDS. This has the correct dimensions of
3.5H x 5.0W x 9.0L mm and thus fits e.g. into the game figure shown on the photo above. Please note that the brick should look authentic, not realistic. Since we are on the subject of authenticity. The 3D printer is very suitable for the creation of bricks, so I have created per print about 211 bricks. Since my simple 3D printer, in contrast to a Resign printer, prints inaccurately, the bricks look more authentic. They all have a basic shape and sometimes small damages or broken corners. You can also use a modeling knife, pliers, or a file to help with this by adding small damages and scratches.Since I use painters tape on my 3D printer bed, the bricks get a stone texture on the front, which looks great.
I also decided to use this method of production because I want to save time. This way, I only have to clean the printed bricks briefly with a pair of pliers and can then use them. Unfortunately, the printing time is quite long, and with the setting of 0.1 mm for one layer, the printing of 211 bricks takes 13 hours. But the details are cleaner and look more like a quality product. But since I don't have to watch the printer, that doesn't affect me. I can spend time planning or doing other projects in the meantime and concentrate better. Personally, I don't see a 3D printer as a killer that destroys my creativity, but gives me more room for it. I want the bricks to look authentic already, but I have no interest in sitting at my work table for hours with a modeling knife. Walls or other brick models off the shelf I also do not want. The models or terrain object should already have my own style, so that these are recognized by people.
I have a larger project that use the bricks and am satisfied with the texture. At certain requirements it is quite good if you have bricks, which was recreated like the original form. But sometimes you just want to blend a wall because it looks better or saves material. Therefore I created the flatbrick as a 3D model. These are only 1.0 mm high and can be glued very easily on a wall or base. Especially if you have e.g. in a passage or a small bridge less space these fit quite well. They still look like real stones. I glued a few flatbricks on a mini wargaming base for testing and quickly primed and drybrushed with white. The result looks quite good in my opinion, if you want to cover a mini base with bricks, for example.

 European Standard Model Brick
 Of course, there is also the ASMB (American Standard Model Brick) which is calculated in the Imperial Unit System.

 PDS, Public Domain Standard. A public domain standard to protect dimensions or design objects from access by corporations and patents. This standard should be available for the whole humanity and accessible for everyone, e.g. model maker.
