title: Functionalized bio-artifact fabricated via selective slurry extrusion. Part 1: Preparation of slurry containing tourmaline superfine powders.
abstract: The far infrared dental porcelain slurry for fabricating artificial tooth via selective slurry extrusion (SSE) of solid freeform fabrication (also known as rapid prototyping) techniques was prepared by using tourmaline as additive and employing ball-milling approach. After characterization by transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectrometry, it was found that the far infrared emission properties of the dental porcelain were apparently improved in the ranges of 2000-1201 cm(-1) and 881-600 cm(-1). This is due to the increase of the number of infrared active bonds that are from the tourmaline superfine powders. Moreover, it was also found that the tourmaline superfine powders can improve the pseudo-plastic properties of dental porcelain slurries, which results from the increase of the absolute value of zeta potential of the suspensions. Slurries with pseudo-plastic behavior are highly desirable in controlling the shape of the extrudate during solid freeform fabrication. With the functionalized material, a variety of bio-artifacts beneficial to body health can be built by using selective slurry extrusion machine.
