Abstract
The invention provides bioactive glass, which is used for solving the problem that a large amount of adhesive needs to be mixed in the existing bioactive glass. The bioactive glass comprises: 60-80% by weight of a substrate, 10-30% by weight of a binder and 1-10% by weight of a non-ferrous metal oxide, the non-ferrous metal oxide comprising a metal element, and the metal element may be a transition metal element selected from the group consisting of one or more of vanadium, chromium, iron, cobalt, nickel and copper. The invention further relates to a method for manufacturing a bioactive glass three-dimensional product by using the bioactive glass.
Description
Technical Field
The present invention relates to a bioactive glass, in particular a bioactive glass for selective laser sintering, and further relates to a method for manufacturing a bioactive glass three-dimensional product by using the bioactive glass.
Background
Bioactive glass (BAG) is a biocompatible material that can be dissolved in an aqueous medium and is capable of dissolving in an aqueous mediumCan be connected with bone tissue and soft tissue, and is widely applied to the manufacture of dental fillers (dental filling materials) and bone implants (bone implants). The composition of the existing bioactive glass comprises silicon dioxide (SiO)2) Sodium oxide (Na)2O), calcium oxide (CaO) and phosphorus pentoxide (P)2O5) For example, 45S5 bioactive glass comprises, in weight percent, 45% silica, 24.5% sodium oxide, 24.5% calcium oxide, and 6% phosphorus pentoxide, wherein the molar ratio of calcium to phosphorus (molar ratio) is 5: 1.
three-dimensional printing (3D printing), also called Additive Manufacturing (AM), refers to a processing technique of melting material powder by using different energy sources under computer control, and stacking the material powder layer by layer after melting and curing to form a printed product. In the Selective Laser Sintering (SLS) method developed in recent years, laser sintering material powder is used, and after a low-melting-point binder added to the material powder is heated and melted, the material powder is bonded with high-melting-point powder such as ceramic or metal, and the high-melting-point powder and the ceramic or metal are sequentially stacked layer by layer until the printing operation of a three-dimensional object is completed, so that the method has the advantages of wide applicable materials, high molding efficiency, high material utilization rate and the like; however, when bioactive glass is used as the material powder in the selective laser sintering method, it is often necessary to add a large amount of binder due to its high melting point, for example, stearic acid (stearic acid), polyvinyl alcohol (PVA), Polycaprolactone (PCL), polylactic-co-glycolic acid (PLGA), etc. are used to assist the formation of the product, and the addition amount of the additive even needs to be more than 50%, which not only greatly affects the biocompatibility of the formed three-dimensional object, after forming into a three-dimensional object, degreasing and sintering (sintering) at high temperature is additionally required, holes may be formed on the surface of the formed three-dimensional object, resulting in insufficient structural strength (structural strength) of the formed three-dimensional object, in other words, the existing bioactive glass is not suitable for the material powder used as the selective laser sintering method.
In view of the above, there is a need for a novel bioactive glass and a method for producing a three-dimensional bioactive glass product using the bioactive glass.
