Prai 3D - Stoneware for 3D printing

from 28.15

Developed by Spanish company CERAMICA COLLET, S.A., their popular PRAI, high fire white body with 40% impalpable grog (up to 80 Mesh) was adapted for 3D printing. Its particular white ivory color after firing is much appreciated and provides an excellent ware for glazes and coloring oxides. Besides, its characteristics offer an excellent behaviour during drying and firing. Available in extruded body with the ideal humidity for 3D printing. Presented in a practical cylindrical format with double packaging. Each bag is double packed and weighs 11 lbs.

The real advantage with pre-prepared and de-aired clay, is there is no need for a pug mill. This simplifies the whole process and makes the initial startup and learning experience simpler. All that you need is a wall-mounted hand loader and Scio pre-prepared clay.

It's a simple process of unwrapping the clay and forming it into a cylinder small enough to place inside the hand loader. At this point the polycarbonate tube is attached to the bottom of the hand loader and the clay is gently pushed into the tube.
That's it. At this point you're ready to go. Mount the tube into the extruder and you will have superior results from the very beginning.

Here's a demonstration of loading the tubes from our Instagram:
