The ceramic 3D printer cannot completely stop the extrusion of clay and the clay itself cannot print all forms because of its softness, resulting in random errors and unexpected things in the printing of some models. But it's the uncertainty and the texture of machine error that fascinates me a lot. The phenomenon that the machine has problems when printing, I feel it is just like our body has some small problems and changes. I play with it, I collaborate with it, I destroy it then I rebuild it. I combine 3D print and hand-made methods together, where there is a typo error, there are nodules. The addition of a 3D printer makes my ceramic art creation more interesting, and also brings some conflicts into the works. The conflict between new technology and old hand craft methods, also the conflict between error and perfection.
