Effect of mechanical recycling on the mechanical properties of PLA-based natural fiber-reinforced composites
(MDPI, 2023-04-06)
The present study investigates the feasibility of utilizing polylactic acid (PLA) and PLAbased
natural fiber-reinforced composites (NFRCs) in mechanical recycling. A conical twin screw
extrusion (CTSE) process was utilized ...
Heat dissipation plays critical role for longevity of polymer-based 3D-printed inserts for plastics injection moulding.
(MDPI, 2022-10-08)
Injection moulding is a polymer processing method of choice for making plastic parts on
industrial scale, but its traditional mould is made from tooling steel with time-consuming and costly
production. Additive manufacturing ...
Enhancement of scaffold in vivo biodegradability for bone regeneration using P28 peptide formulations
(MDPI, 2023-06-13)
The field of bone tissue engineering has shown a great variety of bone graft substitute
materials under development to date, with the aim to reconstruct new bone tissue while maintaining
characteristics close to the ...
Bone tissue engineering scaffold optimisation through modification of Chitosan/ceramic composition
(MDPI, 2023-06-01)
A large bone defect is defined as a defect that exceeds the regenerative capacity of the bone. Nowadays, autologous bone grafting is still the gold standard treatment. In this study, a hybrid bone tissue engineering scaffold ...
Investigation of thermal. mechanical and shape memory properties of 3D-printed functionally graded nanocomposite materials
(MDPI, 2023-09-28)
In this study, a 3D-printed photocurable resin was developed by incorporating graphene
nanoplatelets functionalised with melamine to investigate the thermal, mechanical, fracture and
shape memory behaviours. The objective ...
Designing sustainable polymer blends: tailoring mechanical properties and degradation behaviour in PHB/PLA/PCL blends in a seawater environment
(MDPI, 2023-06-29)
Biodegradable polyesters are a popular choice for both packaging and medical device manufacture owing to their ability to break down into harmless components once they have completed their function. However, commonly used ...

Triangular Silver Nanoparticles Synthesis: Investigating Potential Application in Materials and Biosensing
(MDPI, 2023-07-11)
Triangular silver nanoplates (TSNPs) exhibit unique optical and antimicrobial properties due to their shape, sharp edges, and vertices. In this study, TSNPs were incorporated into biopolymer blends (bacterial cellulose ...
Rheological behaviour of ABS/metal composites with improved thermal conductivity for additive manufacturing
(MDPI, 2023-11-17)
Metal-reinforced polymer composites are suitable materials for applications requiring special
thermal, electrical or magnetic properties. Three-dimensional printing technologies enable these
materials to be quickly shaped ...
Post-process considerations for photopolymer 3D-printed injection moulded insert tooling applications
(MDPI, 2024-04-17)
Injection moulding (IM) is a manufacturing technique used to produce intricately detailed
plastic components with various surface finishes, enabling the production of high-tolerance functional
parts at scale. Conversely, ...
