Research Progress of 3D Printing Technology in Manufacture of Pharmaceutical Films
The pharmaceutical films have the characteristics of good patient compliance,convenience for carrying and taking,and accurate dosage.3D printing technology is an additive manufacturing technology based on computer-aided design models,which generally builds objects by layer-by-layer printing and stacking.It has the advantages of providing complex structures,developing compound preparations and personalized medicines.This review gives an overview of the widely used 3D printing technologies in the preparation of pharmaceutical films,including inkjet printing,fused deposition molding,and semi-solid extrusion.Then,the formulation composition and key process parameters of 3D printing technologies are briefly outlined.It is hoped that this review can provide some references for further researches on the application of 3D printing technology in the field of pharmaceutical films.
