Three dimensional(3D)printing technology was utilized to fabricate a new type of drug implant with complicated architectures,employing levofloxacin(LVFX)and rifampicine(RFP) as model drugs.The prepared drug implant prototype consists of a double-layer structure,of which the upper region is a reservoir system containing RFP and the lower region is a matrix one containing LVFX.The release test in vivo revealed that LVFX was released in the early stage;no RFP was de-tected until 8th day;both of them continuously released more than 6 weeks.Therefore,3D printing technology provides a precise and feasible method to fabricate a controlled-releasing drug implant with complicated architectures and this drug implant may present a new strategy for the prophylaxis and treatment of bone diseases such as combined bone infections and bone tuberculosis in the near future.
