This paper shows how fused decomposition modeling (FDM), as a three-dimensional (3D) printing technology, can engineer lightweight porous foams with controllable density. The tactic is based on the 3D printing of Poly Lactic Acid filaments with a chemical blowing agent, as well as experiments to explore how FDM parameters can control material density. Foam porosity is investigated in terms of fabrication parameters such as printing temperature and flow rate, which affect the size of bubbles produced during the layer-by-layer fabrication process. It is experimentally shown that printing temperature and flow rate have significant effects on the bubbles’ size, micro-scale material connections, stiffness and strength. An analytical equation is introduced to accurately simulate the experimental results on flow rate, density, and mechanical properties in terms of printing temperature. Due to the absence of a similar concept, mathematical model and results in the specialized literature, this paper is likely to advance the state-of-the-art lightweight foams with controllable porosity and density fabricated by FDM 3D printing technology.

Introduction: While stroke remains a leading cause of death and disability, recent advances in endovascular technology an important opportunity to make a significant impact in clinical outcomes. However, training opportunities are rare, preventing dissemination of these techniques. Hands-on training is further complicated by the critical time to therapy associated with stroke treatment. This physical simulator was built for neurosurgical residents and fellows to practice mechanical thrombectomy. Methods: A simplified virtual model of the anterior cerebral circulation was created based on patient imaging. This luminal model was 3D printed using flexible filament and attached to a guide catheter at the proximal carotid to provide endovascular access and an IV tube at the distal M2 branches to permit outflow. A 7Fr sheath was also connected at the anterior cerebral artery to permit placement of a simulated clot model and simulate a proximal M1 occlusion. This entire construct was placed into a container of polyvinyl alcohol (PVA) and after crosslinking the flexible print was removed. Results: Using 3D printing technology and polymer hydrogels, a low-cost, high fidelity stroke model was achieved. Despite its simplified anatomy, the model permitted realistic wire and catheter navigation through the different segments of the internal carotid and middle cerebral arteries. The ACOM sheath provided a convenient method to reliably place an embolism and created a life-like proximal M1 occlusion. Recanalization was performed using the solumbra technique, which is used in live-patient cases. Conclusions: This model demonstrated proof of concept for a mechanical thrombectomy simulation. The angiographic profile and response to endovascular tools created a training experience similar to live endovascular procedures. As the model is perfected visually and mechanically, next steps are to perform validation studies and create a training curriculum.

Placing dielectric lens structures into an antenna's aperture has proven to be one of the most reliable methods of enhancing its gain. However, the selected material and the prototyping method usually limit their fabrication process. With the advances in 3D printing technology and their applications, the microwave designs that were either impractical or impossible in the past to manufacture using traditional methods, are now feasible. Herein, a novel prototyping method by using 3D-printer technology for low-cost, broadband, and high gain dielectric lens designs has been presented. Firstly, the elliptical lens design has been modeled in the 3D EM simulation environment. Then fused deposition modeling based 3D-printing method has been used for the fabrication of the dielectric lens. The measured results of the 3D printed antenna show that the lens antenna has a realized gain of 17 to 20.5 dBi over 8-12 GHz. Moreover, the comparison of the prototyped antenna with its counterpart dielectric lens antenna in the literature has indicated that the proposed method is more efficient, more beneficial, and has a lower cost.

Uchebn. Zaved. Khim. Khim. Tekhnol. 2017. V. 60. N 1. P. 87-94.This article contains results of composition optimization of thermoplastic polymeric mixture for the development of new low flammable material for molten thread 3D-printing technology. In order to receive qualitive polycarbonate - main material for aviation purpose functional products- a couple of tasks were solved – namely decreasing of polycarbonate melt viscosity and flammability characteristics. On the first step polybutylene terephthalate (PBT) and ABS-plastic were used for decreasing in polymeric melt viscosity. Both PBT and ABS have low viscosity melts. Incorporation of these substances into polycarbonate leads to decreasing in effective viscosity and consequently in processing temperature. On a second step the influence of halogenated fire retardant decabrombiphenyl oxide (DBDFO) in amount of 3-10% on flammability characteristics (combustibility, smoke generation, oxygen index, heat release intensity) of researched mixtures was investigated. Fire retardant incorporation allows decreasing the duration of residual burning from 22 to 1-3 s and thus, transfering material from burning to self-extinguishing type. Investigation of smoke generation shows that all mixtures belong to III group of medium fumed materials with smoke generation properties not exceeding upper level (for this group) – 200 units. Besides, it has been shown that incorporation of DBDFO permits to decrease maximum velocity of heat liberation, 18-40% reduce total amount of liberated heat during first two minutes and 26-40% increase in the time of maximum reaching. It has been figured out that increasing in fire retardant amount leads to insignificant increasing in strength properties, decreasing in tensile strength and deformation characteristics. This may be explained by the presence of fire retardant fractions having lower level strength and deformation properties. In this way basing on the conducted studies it has been shown that polycarbonate mixture comprising rheology modifier and fire retardant possesses viscosity similar as 3D-printing suitable materials (ABS, Nylon-618) and advanced flammability characteristics. Investigation results may be used for creating of aviation interior functional products satisfying to Aviation Rules standards for fire hazard and capable for recycling by 3D-printing technology.
