Dual-Phase Materials Extrusion Process for Rapid Fabrication of Ceramic Dental Crown

Abstract

A novel ceramic forming process, dual-phase materials extrusion process based on solid freeform fabrication (also known as rapid prototyping), has been developed. It is a kind of selective slurry extrusion (SSE) technique previously proposed in our group. The dual-phase materials extrusion machine was constructed with micro-extrusion system and 3-axial positioning system. To demonstrate the usability of this machine, a functionalized dental crown was directly fabricated with support material and dental material from 3D model (STL format) of a human tooth. The fabrication time is usually in 20-50 min.

Optimization of Sintering Time and Holding Time for 3D Printing of Fe-Based Metallic Glasses

“…Pneumatic injection additive manufacture is also known as slurry direct writing technology. It is a non-mold forming method based on the principle of pneumatic injection that uses a liquid suspension, slurry, or colloid as the printing material [10][11][12]. Recently, the technology of pneumatic injection additive manufacture has been widely used in the additive manufacture of metals [13][14][15], ceramics [16,17], batteries [18], biomedical engineering scaffolds [19,20], and biological tissue [21].…”
