What shapes tessellate perfectly?

Squares, equilateral triangles, and regular hexagons are the only regular polygons that tessellate perfectly (tile a plane with no gaps). Hexagons are the most efficient, enclosing the most area per perimeter.

How do I add gaps between tiles for a grouted look?

Set the gap width to 0.8-1.2mm for a visible grout line effect. For FDM printing, gaps smaller than your nozzle diameter may not print cleanly. A gap of 2x nozzle width gives the cleanest result.

Can I print tessellated panels on a standard printer?

Yes. For panels larger than your build plate, split them into sections and join them. Each section should end at a tile boundary for clean joins. Use alignment pins or dovetails to connect sections.

What is the best tile size for 3D printing?

Tiles between 10-30mm work well on most FDM printers. Smaller tiles show more detail but take longer to print and may lose definition. Larger tiles are faster but may not look as intricate.

How We Calculate This

Tessellation Formulas

Tiles per row = Surface width / (Tile size + Gap)
Tiles per column = Surface height / (Tile height + Gap)
Total tiles = Tiles per row x Tiles per column
Coverage = Total tiles x Tile area / Surface area x 100%

Hexagonal tiles use hex packing geometry where each row is offset by half a tile width. Triangle areas use the standard equilateral triangle formula.
