Opis:
The article presents a new tool for modeling parts produced by rapid prototyping (RP) technologies that has great potential for building structures with programmable properties, especially for items related to the energy dissipation during deformation. Using a wide variety of building materials and controllable part growing is the most important benefit for industry implementation of RP technology. Mass deployment is also hampered by the high price of equipment and materials for the technology.

Opis:
Fused Deposition Modelling technology allows to produce elements of very complex shapes without any additional tooling, which is why it has a broad range of industrial applications. Possibility of manufacturing parts with controlled degree of internal filling allows to shorten the manufacturing time and reduce volume of used material. The paper presents influence of layer filling type on part capability of carrying loads and economical coefficients of the manufacturing process. A problem of mechanical properties is important especially in case of elements used as functional prototypes. The paper presents methodology and results of experimental strength tests of samples with various types of internal filling. As a build material for test samples, ABS material was used. Composite samples were also used the ABS matrix produced by Fused Deposition Modelling was filled with chemically hardening polyurethane resin in a process developed by authors. The samples were subjected to destructive testing and their strength properties were compared.

Opis:
The paper presents a method, developed by the authors, for manufacturing polymer composites with the matrix manufactured in a layered manner (via 3D printing – Fused Deposition Modeling) out of a thermoplastic material. As an example of practical application of this method, functional prototypes are presented, which were used as elements of foundry tooling – patterns for sand molding. In case of manufacturing prototype castings or short series of products, foundries usually cooperate with modeling studios, which produce patterns by conventional, subtractive manufacturing technologies. If patterns have complex shapes, this results in high manufacturing costs and significantly longer time of tooling preparation. The method proposed by the authors allows manufacturing functional prototypes in a short time thanks to utilizing capabilities of additive manufacturing (3D printing) technology. Thanks to using two types of materials simultaneously (ABS combined with chemically hardened resins), the produced prototypes are capable of carrying increased loads. Moreover, the method developed by the authors is characterized by manufacturing costs lower than in the basic technology of Fused Deposition Modeling. During the presented studies, the pattern was produced as a polymer composite and it was used to prepare a mold and a set of metal castings.

Opis:
The paper presents results of experiments aimed at determination of range of critical orientation for parts manufactured additively using the Fused Deposition Modelling method, out of ABS material. Numerous previous observations of plastic parts manufactured additively using the FDM process allowed concluding, that change of values of the manufacturing orientation (i.e. direction of layer slicing plane) has large influence on the macrostructure of obtained parts, thus affecting their strength and behaviour under load – the material behaves either as a thermoplastic with a yield point or as a brittle material with no yield point. The paper presents methodology and results of experiments aimed at determination of a certain value or value range, at which transition between the two behaviours occurs. The experiments consisted of tensile tests performed on samples manufactured additively in a pre-selected range of orientations. The obtained results – a value range valid for the selected type of load and sample shape – will be useful in future to help select an optimal orientation of part for a defined task.

Opis:
Tematem prezentowanej pracy jest prototyp elektrycznej protezy dłoni z użyciem technik wytwarzania przyrostowego. Przedstawione wyniki są rezultatem pracy inżynierskiej [1] pt. Prototypowanie elektrycznej protezy dłoni z użyciem technik wytwarzania przyrostowego, która została zrealizowana na kierunku Inżynieria Biomedyczna na Politechnice Poznańskiej. Celem pracy było zaprojektowanie i wytworzenie elektrycznej protezy dłoni metodą osadzania topionego materiału. Zastosowane rozwiązanie umożliwiło wykonanie sztucznej kończyny z możliwością zginania palców, a także przeciwstawiania i odprowadzania kciuka. Jej sterowanie zrealizowano przez elektrody, które odbierały sygnały napięcia mięśniowego. Były one przekazywane do czujnika pomiaru aktywności mięśni EMG, który przesyłał je do Arduino Leonardo. Płytka z mikrokontrolerem sterowała serwonapędami, których obrót orczyków wprawiał w ruch poszczególne palce. Założeniem pracy było zaprojektowanie lekkiej, funkcjonalnej i tańszej od dostępnych na rynku rozwiązań protezy dłoni. Część teoretyczna pracy omawia protezy i ich podział, przyczyny protezowania i stopnie amputacji. Część praktyczna przedstawia proces projektowania wraz z doborem parametrów sztucznej kończyny oraz jej wytworzenie. W zakończeniu podsumowano właściwości protezy takie jak: funkcjonalność, masa, koszt oraz czas wytwarzania elektrycznej protezy dłoni.
The subject of this work is the prototyping of an electrical hand prosthesis using additive manufacturing technologies. The results, which were presented at Poznan University of Technology, represent a part of an engineering thesis of Biomedical Engineering Prototyping of electrical hand prosthesis using additive manufacturing technologies. The aim of this work was to design and manufacture a hand prosthesis by fused deposition modelling. The applied solution allowed to manufacture an artificial limb with ability to flex the fingers and to aditionally make moves such as the opposition and reposition of the thumb. The control was regulated by biomedical electrodes, which received the muscle tone signals and send them to the EMG muscle activity sensor and further to the Arduino Leonardo. The board with a microcontroller controlled the work of servomechanisms in which the rotation of the horn caused the fingers' movement. The assumption of this work was to design more lightweight, functional and cheaper solutions compared to commercially available electrical hand prosthesis. The theoretical part of this work discusses prostheses and their types, causes of substitution of prosthesis and levels of amputation. The practical part of this paper presents the process of designing an artificial limb with choices of parameters and manufacturing of the prosthesis. The conclusion of this experiment gives evidence for the existence of features of the prosthesis such as: functionality, mass, cost and manufacturing time.

Opis:
The purpose of this research is unsatisfactory state of knowledge of the abrasive wear of composites with thermoplastic polymer as matrix material and reinforcing material in the form of short and focused carbon fibers that can be used in additive manufacturing technologies. The paper presents a conceptual design of an extrusion head used in Fused Deposition Technology, which allows for the implementation of appropriately stacked fibers at the level of detail production. Finite element simulation was performed to simulate the thermal effect of the system to demonstrate the effect of head cooling on the system. The assumed extrusion temperature of the material was obtained at a uniform nozzle temperature and stable temperature of the entire system. Flow simulation of thermoplastic polymer was carried out in the designed extrusion nozzle. By supplying 0.5 mm wire of 1.75 mm diameter thermoplastic material to the nozzle, the extrusion rate was 0.192 m/s. The proper design of the extrusion head for the intended applications has been demonstrated and the purpose of further research in this field has been confirmed.

Opis:
Low drug loading efficiency is the limiting factor in the use of pre-fabricated filaments for 3D printing of pharmaceuticals. The aim of present study was to modify the material properties of pre-fabricated filament by incorporating the suitable solubilizing aids in order to enhance the drug loading efficiency. Loratadine was loaded into PVA filaments by using solubilizers (Soluplus®, Sodium lauryl sulphate) and plasticizers (glycerin and Polyethylene glycol-400) and the printability of filaments was investigated. The treated filaments were characterized for morphology and diameter changes, drug content, FTIR and thermal properties and printed into tablets of suitable dimensions. The printed tablets were also characterized for drug assay and drug release. The results have shown that the surface of different drug loaded filaments become rough with almost no change in diameter hence, these filaments remained printable. However, there was 7 to 24 times enhancement in drug content of filaments treated with particularly those pretreated with glycerin and soaked in drug solution containing Soluplus. The printed tablets have also shown almost similar drug content as their precursor filaments and the release followed diffusion mechanism in most of the formulations. The study concludes that the treatment of PVA filament with solubilizer aids has significantly improved the drug loading entrapment without compromising the printability.
