In the recently published ‘ 3D printing of kaolinite clay with small additions of lime, fly ash and talc ceramic powders ,’ Carlos F. Revelo and Henry A. Colorado explore the use of direct ink writing to create innovative ceramics, using a variety of inexpensive powders such as lime, fly ash, and talc—all commonly found in the ceramics realm—around the world.

3D printer used in this research Kaolinite is a clay material and is a natural mineral found in many countries. It is also commonly used as an additive in the following: Paper coating formulations Ceramics Plastics Adhesives Pharmaceuticals The result of kaolinitic raw materials depends on the parent rocks, which may be based on granite, rhyolite, syenite, trachyte, gneiss or arcose. The researchers used kaolinite clays from Colombia, stating that they were most ‘abundant’ in the area. “The world today demands new technologies for the production of ceramics […]
