As evidenced by this article, plastic tends to dominate 3D printing as the primary print material. We’ve explored some other options already, and here’s another: clay. Boasting earthenware properties, clay 3D printing filament contains a mixture of clay and polymer.

There are a few different companies offering stone/earthen material-based filaments, with clay (often marketed as ceramic) being the one with perhaps the strongest use case: faux-pottery.
A common characteristic shared between these filaments is brittleness, meaning care is required to properly handle and print them.
Lay Filament’s LAYCeramic is one example of a ceramic filament that achieves near-authentic results. Fireable in a kiln after printing, the polymer binding the ceramic particles within de-binds to leave behind a slightly shrunken, but hardened print ready for glazing and other ceramic post-processing effects.

When Should I Use Clay/Ceramic 3D Printer Filament?

When you’re looking for a handmade earthenware look paired to the impossibly precise repeatability 3D printing gives.
