Special Issue "Biomedical Applications of Biodegradable Composites"
A special issue of Materials (ISSN 1996-1944).
Deadline for manuscript submissions: 30 April 2021.
The use of biodegradable composites is increasing in the biomedical space. Composites, by their nature, impart the beneficial properties of the individual components while overcoming their limitations through the synergistic combination of distinctly different materials. However, the potential of biodegradable composites can only be achieved if there is intimate, uninterrupted contact between the reinforcement and matrix phases of the composite and in the case of nanocomposites exfoliation of the nanoparticles. This can, in itself, be difficult to achieve while retaining the biocompatibility of the final construct, as the matrix and reinforcement agent are generally not compatible. Approaches for this can include the following:
- Surface treatment
- Reactive extrusion
- Process optimisation
Biodegradable composites can generally be processed using traditional manufacturing techniques but can also utilise emerging technologies such as additive manufacturing to produce final fabricated implants. These enable easy production scaling, which can expediate the uptake of these technologies.
Furthermore, while the biodegradable nature of these composites allows tissue to repair uninterred as the implant degrades, the biocompatibility of the degradation components must be given special consideration.
Nevertheless, these composites can be used to overcome shortfalls of traditional materials in a variety of applications such as:
- Tissue engineering
- Bone repair
- Cardiovascular, urinary, and other stents
- In-situ controlled release of active pharmaceutical ingredients

Title: Precision and strength properties of PLA biodegradable material for producing of dental and orthodontics patterns
Author: Juraj Beniak
Abstract: The PLA material is produced from the natural sources and the biggest advantage comparing to conventional thermoplastic produced from oil is that they are biodegradable. The another advantage is that the PLA material is easy use for 3D printing with low warping, low printing temperature and good strength properties. The PLA material is also suitable as a basic for composite material. Nowadays the PLA plastic material is also used for for preparation of dental and orthodontics patterns for preparation of different medical models. So there is necessity to know the material and accuracy properties of produced models if there are suitable for our application and if the PLA plastic can replace others usually used materials suitable form FDM technology. Presented paper deals with experiments, where the strength of produced specimens is measured and compared to others usual used thermoplastic suitable for FDM additive manufacturing technologies. The second part of presented research is experimental determination of specimen precision produced by FDM printing. They are used different shapes and dimensions and also different software for 3D model slicing and 3D model printing data preparation. All the experiments are statistically evaluated by statistical methods.
