Effects of excipient properties on pharmaceutical printlet fabrication via selective laser sintering 3D printing
In this study, the impact of excipients on the quality of printlets manufactured using selective laser sintering (SLS) 3D printing was investigated. Various thermoplastic polymers, commonly used as pharmaceutical additives, and mannitol of different particle property grades, were used as excipients. SLS can produce complex structures and customize drug release rates; therefore, it can be used for personalized medicine. The significance of selecting suitable excipients, focusing on their powder flowability and printability, and their influence on the printlet properties was evaluated. An optimal amount of yellow iron oxide, a necessary laser-absorbing agent for printlet formation, was determined. Results revealed that excipients with optimal flow and shape characteristics considerably enhanced the printlet quality. The relation between the powder properties of excipients (internal friction angle, shear adhesion force, and flow function coefficient) and the SLS printing outcomes was evaluated using the powder shear cell test. The powder properties considerably affected the application of the powder layer using a spreader from the powder reservoir to the building platform. Moreover, the electron laser density impacted the printlet hardness. The as-fabricated printlets exhibited higher porosity and faster dissolution rates than traditional tablets, suggesting the potential advantages of using SLS in drug manufacturing.
期刊介绍:
The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide.
The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them.
Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
