Modelling Decorative Paving Various Size Sheets 3D print model

On the market, several manufacturers make sheets of different building materials and have thought about doing some of these for a while. When someone approached me to look at doing these they complained that the cost of these sheets was getting more and more expensive, so I thought it was time to add them to my collection.

I had thought about doing them in the past with my resin printer but are probably better suited to FDM printing, Whilst researching these designs I liked the decorative paving that used different sized paving slabs to create a nice looking patio or paving, this design is based on slabs that are approximately 300mmx300mm and 600mmx600mm ** I have also found if you print this design inverted you can get a nice pattern on the slabs from your print bed if you have something like a textured PEI sheet**. This design can be used as a patio of footpath or something similar.Other options will be added as and when I get to them, so if not available please wait or feel free to contact me.

I have included the following sheet sizes (sheet sizes are based on brick size in the OO scale).20mm x 100mm, 40mm x 100mm, 60mm x 100mm, 80mm x 100mm, 100mm x 100mm, 120mm x 100mm.20mm x 200mm, 40mm x 200mm, 60mm x 200mm, 80mm x 200mm, 100mm x 200mm, 120mm x 200mm.

The sheets are 1.56mm thick which is based on the layer height being 0.12mm. Additional Lines on technical design pictures are from how I created the design, its a pattern that is replicated and lines don't appear in STL file or printed item.

designed at OO gauge, 1/76.2 scale but can easily be scaled for other gauges.for HO gauge print at 87%, 1/87 Scale,for TT gauge print at 63.5% 1/120 Scale,for O gauge UK at 175%, 1/43.5 Scale,for O gauge International print at 158%, 1/48 Scale,for N gauge print at 51.49%, 1/148 Scale, (Caution: I have not printed this model in N gauge so I can’t guarantee its printability)

Examples in the pictures were printed on a Bambu Labs A1 FDM Printer.As normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.

For FDM printing, I used a 0.2mm nozzle and a layer height of 0.12mm using PLA+ filament. You can use a 0.4mm nozzle but the corners of the brick won't be as sharp, can also be printed in PLA but I recommend PLA+ or PETG for better durability. Note print times vary based on the amount of bricks for the sheet, this isn't a design that uses a lot of filament.
