Mass customization of polylactic acid (PLA) parts via a hybrid manufacturing process
(MDPI, 2022-12-10)Mass customization is the development of items tailored to specific customers, but produced at low unit cost in high-volume. In this context, hybrid manufacturing (HM) combines fused deposition modeling (FDM) and injection ... -
Mass-customization of oral tablets via the combination of 3D printing and injection molding.
(Elsevier, 2019-10-05)The new frontier of medicine is the personalization of treatment to match a patient’s individual needs. Fused-filament fabrication (FFF) offers a platform for the personalization of drug dosage forms, but one of its chief ... -
Material considerations for fused-filament fabrication of solid dosage forms.
(MDPI, 2018-04)Material choice is a fundamental consideration when it comes to designing a solid dosage form. The matrix material will ultimately determine the rate of drug release since the physical properties (solubility, viscosity, ... -
Material considerations for fused-filament fabrication of solid dosage forms.
(MDPI, 2018-04-02)Material choice is a fundamental consideration when it comes to designing a solid dosage form. The matrix material will ultimately determine the rate of drug release since the physical properties (solubility, viscosity, ... -
Material testing, design & construction of a laboratory-scale FRP composite.
(ACIC, 2017-09)Pedestrian loading on flexible structures such as footbridges, grandstands and lightweight floors is an area, which is receiving significant attention from the research community of late. One of the key parameters in ... -
Matrix and reservoir-type multipurpose vaginal rings for controlled release of dapivirine and levonorgestrel
(Elsevier, 2016-09-10)A matrix-type silicone elastomer vaginal ring providing 28-day continuous release of dapivirine (DPV) a lead candidate human immunodeficiency virus type 1 (HIV-1) microbicide compound has recently demonstrated moderate ... -
Mechanical properties of anodic titanium films containing ions of Ca and P submitted to heat and hydrothermal treatment.
(Elsevier, 2016-12)Anodic oxidation is a technique widely used to improve the bioactivity of Ti surface. In this study, micro-arc oxidation (MAO) was used to obtain an anodic film incorporating Ca and P ions to evaluate the effect of heat ... -
Methods of Characterization of 3-Printed Objects
(CRC Press, 2024)The popularity of 3D printers has increased in the past decade, partially attributed to the expiration of significant patents and the availability of cost-effective equipment. The utilisation of 3D printing technology ... -
Micro-injection mouding of PEO/PCL blend-based matrices for extended oral delivery of Fenbendazole
(MDPI, 2023-03-10)Fenbendazole (FBZ) is a broad-spectrum anthelmintic administered orally to ruminants; nevertheless, its poor water solubility has been the main limitation to reaching satisfactory and sustained levels at the site of the ... -
