The increase in the number of people affected by genetic and infectious diseases resistant to conventional treatments has led to the need to develop new medical treatments by understanding the mechanisms of action and the targets of pharmacological action at the molecular level. As well as, to develop more specific transport systems for existing hydrophobic and hydrophilic drugs in order to increase the therapeutic efficacy of these drugs. Implantable drug delivery devices (DDDs) technology offer several advantages over conventional methods such as oral or parenteral dosage form, allowing specific drug administration at the target site, minimizing potential side effects. This therapy may provide controlled release of a medicine for acute and chronic treatments. In recent years, Additive Manufacturing (also known as 3D printing) processes such as Selective Laser Sintering (SLS) has shown great prominence in the biomedical field, and several researchers have conducted studies showing a wide diversity of materials and applications, such as the additive manufacturing of medical products, scaffolds and drug delivery devices (DDDs). SLS is a good alternative to controlling the porosity of bio-inert and bio-absorbable polymeric matrices and, consequently, control the drug release of implantable DDDs. In this study, DDDs with polymeric matrices, hydrophilic and hydrophobic drugs were manufactured and characterized. The structure and properties of the manufactured DDDs were evaluated and correlated with the processing conditions.
