Background: Three-dimensional printing is a revolutionary technique with Computer-Aided Design software and Standard Triangle Language (STL). This software helps print tablet (object) by placing material on the substrate, 3-D printing is an additional process in the manufacturing technology, where a 3-D object forms sub-substrate, the successive material layers are deposited. Method: 3-D printing technology requires technologically operated instruments for the layer-by-layer formulation of Active Ingredients and Excipients for the production of Personalised Medicine (PM) as per need of the individual patient. The techniques used to formulate 3-D printing objects include Stereolithography, Inkjet printing, and fused deposition modelling. Inkjet printig is again divided into continues jet printing and drop on demand. Different polymers are used to formulate such dosage forms like polyvinyl alcohol, poly-caprolactone, poly-lactic acid, etc. Conclusion: In this mini-review analysis, we have reviewed about 3-D printing technology. We have reviewed different dosage forms prepared using 3-D printing technology and discussed different technologies used in the 3-D printing technique.
