Digital fingerprints

I 3D printed two tests pieces for casting some new test shapes and noticed that the printer has made up the texture on the larger angled surfaces.

On the Rhino file the two large surfaces were angled, flat surfaces, it was only at the 3D printing stage that the programme that generates the print path read the file and created this pattern and texture.

I wrote about the use of both digital and hand making in ceramics and how the marks that the machine makes can be beautiful and can be just as important as the marks made by hand. I think it's so interesting that the 3D printer has created this pattern on this shape, I like the idea that the printer is part of the design process and it leaves a mark like the way a fingerprint could be left on a handmade object.

When I made moulds these two pieces that plaster captured the texture of the 3D print and it's picked up by the slip cast. I really like this texture, the layering that's a mark of the printing process also makes me think of the stepped layers in bismuth.

I think angling different surfaces in my CAD file could be a way for me to recreate this texture in other prints.
