Using the "create pattern" function of my CAD software, Fusion 360, I created a grid of duplicate cookie cutters. That enables 3D-printing up to 25 at a time. While it is impossible to remove them while the clay is soft I can leave them in the cutters overnight, the next day they just drop out. Creating the rounded top edges is easily done first using a little stretch wrap as shown, then it is just a matter of pushing the cutter the rest of the way through and setting them aside to dry. This method creates a high-quality edge finish. Of course, the embossed design was first stamped into these Polar Ice porcelain tiles using a letterpress plate.

This is the most complex shape known that can fit together organically, without a pattern (dubbed the Einstein tile, it was discovered by mathematicians in 2023). It has six sides of 1 unit length, six of 1รท1.73205080757 and one side measuring twice the latter. Placing the tiles is tricky because it is only logical to seek a pattern, but there is none. One method is to start with a center tile and move outward in a spiral, being ready to backtrack and place them upside down when a piece cannot be fit. The tile shape is a product of connecting four identical irregular pentagons - each made by cutting a regular hexagon into three pieces. To achieve the maximum precision, 3D print multiple cookie cutters and let them stiffen and shrink in the cutters. To round the upper corners use stretch wrap) when stamping (print cutters in both orientations if doing this). Tiling a floor or wall will present issues with the number of edge tiles that need to be cut. However, cutting at least some custom edge shapes is practical because only 90 and 120 degree angles are needed.

Cookie Cutting clay with 3D printed cutters
We are finding more and more applications for this simple process of cookie-cutting shapes in ceramics. You won't believe whats possible and how easy it is to get started. |
