To expand the chemical capabilities of 3D printed structures generated from commercial thermoplastic printers, we have produced and printed polymer filaments that contain inorganic nanoparticles. TiO2 was dispersed into acrylonitrile butadiene styrene (ABS) and extruded into filaments with 1.75 mm diameters. We produced filaments with TiO2 compositions of 1%, 5%, and 10% (kg/kg) and printed str...

The mechanical and combustion properties of metal-nested composite hybrid rocket fuel grains composed spiral aluminium (Al) frameworks fabricated using three-dimensional (3D) printing with an embedded paraffin-based were investigated. the resulting evaluated by compression tests. In addition, characteristics Al examined in a lab-scale engine gaseous oxygen as oxidizer at initial mass flow rate ...

Unmanned Aerial Vehicles (UAVs) have high popularity, especially in the military field, but are now also being applied to private and public sectors. One of UAV components that require material technology is wing. The latest developed as a for unmanned aircraft wings composite has strength lightweight. This research aims identify materials can be used wing structures. method this qualitative wi...

An important polymer processing technique is additive manufacturing (AM), which enables shape-free design of complex final parts with limited waste during the development change, at least if impact molecular degradation reactions minimized. In present work, polystyrene (PS) and acrylonitrile butadiene styrene (ABS) have been processed via: (i) fused filament fabrication (FFF), separately accoun...

Multi-material 3D printing offers new possibilities regarding product development, allowing design freedom and multiple materials choices in terms of colour polymer type. Material extrusion technologies are among the most popular options for multi-material due to their low equipment cost various thermoplastic materials. However, polymers’ compatibility bond interface must be considered componen...

The electrolyte for dye-sensitized solar cells (DSSCs) is subject of constant innovation, as the problems leakage and drying greatly reduce long-term stability a device. One possible way to solve these use gel polymer electrolytes (GPEs) with gelling structure, which offer different advantages based on used polymers. Here, potential GPE systems dimethyl sulfoxide (DMSO) solvent low-cost, non-to...

In this study, the toxicity of combustion gases polycarbonate/acrylonitrile butadiene styrene (ABS) blends that include aryl phosphates as flame-retardants (FRs) was analyzed according to European railway standard EN 45545-2 (NBS chamber + FTIR). FRs have a significant influence on evolution generated during process. experiment, asphyxiant hydrogen cyanide (HCN) detected at beginning (4 min tes...

Fused deposition modelling, or 3D printing, is an additive manufacturing technique that quickly gaining popularity because of its ability to produce usable parts with several geometries. It provides multiple advantages in everyday life. However, the emerging risks using printers at home issue needs be addressed. estimated a person spends, on average, 80-90% their time inside building, up 60% ho...

Polybutadiene and a co poly mer consisting of 76.5 percent butadiene and 23 .5 percent of styrene were investigated as to t he rates of t heir t hermal degradation . The ra tes for polybu tadiene indicated an act iv:ttion energy of 60 kilocalories per mole. The copolym er had very high init ial rates of degradation, followed by a rapid cirop, so t hat it wa~ not possible to obtain a reliab le a...
