Article Synopsis
- This study explores how various post-printing treatments and aging affect the mechanical properties of 3D-printed materials, specifically focusing on white opaque and flexible photopolymers used in surgical simulators.
- The researchers conducted tensile and Shore hardness tests on 3D-printed specimens with different removal methods (dry vs. water) and surface treatment using glycerol, revealing significant changes in properties like elongation at break and tensile strength.
- Findings show that glycerol increases rigidity in flexible photopolymers initially, but aging restores their elongation, while rigid photopolymers become more deformable over time, highlighting the need for careful material selection and processing for durable surgical models.
In this work, assessment of microplastics (MPs) in commercial vegetable edible oils from Italy and Spain, including extra-virgin olive oil, olive oil, sunflower oil, and mixed seed oil, has been conducted for the first time. The method was based on sample dilution with ethanol:n-hexane (1:3, v/v), homogenization, vacuum filtration on macroporous silicon filters with 5 μm pore diameter to collect MPs, and automatic µ-FTIR spectroscopy for MPs detection and characterization. In the analysis of oil samples, a mean MPs abundance of 1140 ± 350 MPs/L was found.
