Agomelatine (AGM) is an effective antidepressant with low oral bioavailability due to intensive hepatic metabolism. Transdermal administration of agomelatine may increase its and reduce the doses necessary for therapeutic effects. However, transdermal delivery requires crossing stratum corneum barrier. For this purpose, use microneedles efficiency administration. The aim study was prepare agomelatine-loaded hydrogel suitable coating drug AGM. optimized formulations were subjected...
The paper presents the results of experimental study – part research additive technology using thermoplastics as a build material, namely Fused Deposition Modelling (FDM). Aim was to identify relation between basic parameter FDM process model orientation during manufacturing and dimensional accuracy repeatability obtained products. A set samples prepared they were manufactured with variable parameters measured 3D scanner. Significant differences in products same geometry, but different observed.
Numerous experimental studies, including experiments performed by the authors, have shown that part orientation during layer deposition has a very strong influence on final strength of product manufactured additive Fused Deposition Technology.The paper presents results tensile, bending and impact tests samples various orientations, made out ABS material using FDM technology.The these allowed discovering unique phenomenon -with changing orientation, not only values indexes change, but...
The paper presents results of research conducted on a batch additively manufactured individualized openwork wrist–hand orthoses made thermoplastics and designed automatically based 3D-scanned geometry given patient. aim the work was to establish an automated design process find reliable set parameters for rapid affordable manufacturing usable popular 3D printers, with little or no supervision process. motivations, methodology design, plan testing, obtained in terms stability, fit assessment...
The aim of the study was to compare two types mandible reconstructive operations with scapula and fibula free flaps: procedures 3-D models from thermoplastic materials conventional planning surgeries. 8 patients were treated due an advanced oral cavity squamous cell carcinoma. In four a mandibular defect, physical model consisting reconstructed unaffected sites prepared for reconstruction protocol. designed based high resolution CT scans. Assessment comparative functionality (stability...
Growing age and different conditions often require the replacement of orthoses, FDM-based 3D printing can produce them quickly with less investment. In today's market for orthotics, these characteristics are highly desired. Therefore, this study is fully focused on optimization strength analysis FDM 3D-printed ankle-foot orthoses (AFO) fabricated using PLA reinforced carbon fiber (PLA-C). An increase in ankle plantar-flexor force be achieved by reinforcing thermoplastic AFOs CFs. Specially...
This paper presents the results of experiments conducted on a batch additively manufactured customized prosthetic sockets for upper limbs, made thermoplastics and designed automatically basis 3D-scanned limb 3-year-old patient. The aim this work was to compare two different materials—rigid PLA elastic TPE. Two distinct socket designs with various mounting systems were prepared. To find reliable set parameters cheap stable manufacturing usable prostheses using 3D printers, realizing fused...
The paper presents the design and manufacturing process of an individualized wrist orthosis.The patient's upper limb was 3D scanned orthosis designed using a CAD system.Each part consists two different materials that fulfill functions.By double-head Fused Deposition Modelling machine it possible to produce these parts in single without need for additional assembly operations.The has been tested mutual fit parts, strength comfort use.
This paper presents the outcomes of investigations conducted on development procedure a personalized prosthetic device for an adult patient. The individualization is achieved through 3D scanning, followed by semi-automated design using AutoMedPrint system, and low-cost fused deposition modelling (FDM) technology printing. prosthesis aimed use during bicycle riding other sport activities. During experiments outlined in this manuscript, equipped with force movement sensors. purpose to collect...
The article presents the results of research on influence natural moisture a filament made acrylonitrile-butadiene-styrene terpolymer (ABS) mechanical properties and quality products fabricated with fused fabrication (FFF). concept was defined, range its variability identified in reference to ambient humidity. It is shown that change humidity by 10% resulted about 0.05%. an ABS stored package, airtight container, or container absorber are also discussed. last part impact select filaments...
The paper presents design and manufacturing process of an individualized ankle orthosis using additive technologies reverse engineering.Conventional processes orthoses are expensive time consuming Thus, alternative method was proposed.The patient's leg 3D scanned the designed a CAD system.It then manufactured Fused Deposition Modelling technology, assembled fully tested.Positive results were obtained.
Abstract The paper presents results of studies on an innovative approach to mass customization prostheses, namely automated design and rapid manufacturing (3D printing), the basis 3D scanning upper limb a given patient. Two different products are presented – simple mechanical prosthesis cosmetic prosthesis. In both cases, intelligent CAD models, with adaptive geometry changing automatically data from were prepared. digital models built tested using real patients. A special algorithm...
In this study, caffeine-loaded photoresin composites with homogeneous structures, suitable for additive manufacturing of transdermal microneedle systems, were obtained. The properties the varying caffeine concentrations (0.1–0.4% w/w) investigated carbon–carbon double bond conversion using Fourier Transform Infrared Spectroscopy, surface wettability and mechanical a static tensile test nanoindentation, release in ethanol UV-Vis. concentration did not affect final degree conversion, which was...
Purpose This paper aims to study strength properties and accuracy of a new type composites, in which matrix is manufactured additively, whereas infill polyurethane resin. The process manufacturing these composites invented patented by authors. Design/methodology/approach authors developed method was then used build samples for tensile bending tests (according ISO 572 178 standards), as well measurements accuracy. Findings It found that the composite designed allows obtaining both stronger...
The paper presents a method, developed by the authors, for manufacturing polymer composites with matrix manufactured in layered manner (via 3D printing -Fused Deposition Modeling) out of thermoplastic material.As an example practical application this functional prototypes are presented, which were used as elements foundry tooling -patterns sand molding.In case prototype castings or short series products, foundries usually cooperate modeling studios, produce patterns conventional, subtractive...
