Atualmente, a utilização dos recursos de Tecnologia de Informação e Comunicação tem sido cada vez mais significativa. Porém, para deficientes visuais sem o adequado acesso ao computador e demais tecnologias, os obstáculos no que se refere à educação, lazer ou a garantir um lugar no mercado de trabalho podem ser inúmeros. Sabe-se que na educação para cegos os recursos audiovisuais são frequentemente utilizados pelas Instituições de Ensino, o que pode acarretar que eventualmente alunos com cegueira ou baixa visão venham a adquirir uma compreensão fragmentada da realidade, reduzindo o seu interesse e motivação. Assim, torna-se evidente a importância do uso de material didático adequado, e que não recorra apenas a soluções virtuais, uma vez que isso requer elevado esforço imaginário destes indivíduos. Desta forma, este trabalho propõe o desenvolvimento de uma impressora de gráficos em altorelevo com a utilização de tinta de emulsão acrílica com propriedades expansivas ao calor. Para averiguar a viabilidade deste produto propôs-se a construção de um protótipo através de resíduos de equipamentos eletrônicos e posteriormente analisou-se seu desempenho. Este trabalho teve a intenção de colaborar para a utilização da exploração tátil no aprender dos conhecimentos relacionados às disciplinas de Física e Matemática do Ensino Médio, e contribuir também no fornecimento de subsídios para a inclusão deste grupo de alunos em escolas regulares, profissionalizantes e de ensino superior. / Currently, the resource utilization of Information and Communication Technology has been increasingly significant. However, for the visually impaired without adequate access to computers and other technologies, obstacles with regard to education, leisure and secure a place in the labor market can be numerous. We know that in education for the blind, audiovisual resources are often used by the Institutions of Education, which may force eventually students with blindness or low vision to acquire a fragmented understanding of reality, reducing their interest and motivation. Thus, it is evident the importance of using suitable teaching material, which is not only virtual, since its require a high effort imagination from these individuals. Thus, this paper proposes the development of a graphics embossed printer by the use of acrylic emulsion paint with expansive heat properties. To investigate the viability of this product, it was proposed to build a prototype using scrap electronics and subsequently analyzed for their performance. This project has the intention to collaborate in the use of tactile exploration in the learning of knowledge related to the disciplines of Physics and Mathematics in high school. Also contributing to the provision of subsidies for the inclusion of this group of students in regular, vocational and higher education schools.

The thesis deals with 3D printing by the FDM and ambient temperature on print quality. The thesis describes the principle of printing by the FDM method and the occurrence of errors caused by the influence of ambient temperature. The aim of the thesis is to design a heated chamber for RepRap Prusa i3 printer, its construction and subsequent testing of ambient temperature influence on print quality. To test the occurrence of the described errors, specific tests and materials are selected in the work. The result of this work is the recommended ambient temperature in the heated chamber for improved FDM printing.

In this diploma thesis, I focus on the main principles of the HandJet mobile printer. This printer is mostly intended for industrial use to mark products and spaces with 2D and EAN codes. Despite the purely utilitarian function of the printer, I have decided to use it for artistic purposes. I look for its potential in application in the field of graphic design and art. I record the process as a part of the work process of a graphic designer when delivering assignments via research, sketching, and automatic drawing. The key aspect is the exploration of the possibilities of visual form. The result is a series of prints presented in the form of an installation.

The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method. Verification of the results was performed on a vertical milling cantilever FV 25 CNC with control system Heidenhain iTNC 530 using a cutting strategies by PowerMILL CAM software. At the end of the resulting models edit as necessary.

The essence of the work is to test the possibilities specific type of simple 3D printing device, which has recently been getting more and more into the awareness of professionals and the general public. First, the work is focused on presentation 3D printing technology and current professional equipment, in the second part are experimentally evaluated possibilities of of a simple kind of 3D printers followed by assessment of the applicability of the device in engineering practice.

This thesis is about creating library for control of the 3D printing machine. Printer active axes are realized by stepper motors from Microcon Corporation connected with CD30x control unit. Communication between application and control units is via RS232 serial link. Part of this work is dedicated to application showing typical usage of this library.

As a cutting edge manufacturing methodology, 3D printing or additive manufacturing (AM) brings much more attention to the fabrication of complex structure, especially in the manufacturing of metal parts.A number of various metal AM techniques have been studied and commercialized. However, most of them are expensive and less available, in comparison with Selective Laser Melting manufactured stainless steel 316L component.The purpose of this Master Thesis is to introduce an innovative AM technique which focuses on material extrusion-based 3D printing process for creating a Stainless Steel 316L part using a metal-polymer composite filament. The Stainless Steel test specimen was printed using an Fused Deposition Modelling based 3D printer loaded with a metal infused filament, followed by industrial standard debinding and sintering process. Investigation was performed on the specimen to understand the material properties and their behaviour during the postprocessing method. In addition effects of debinding, sintering and comparison of the test Specimen before and after debinding stages was also carried out. Metal polymer filaments for 3D printing could be an alternative way of making metal AM parts. / Som en avancerad tillverkningsmetodik ger 3D-printing eller additiv tillverkning (AM) mycket mer uppmärksamhet vid tillverkning av komplex struktur, särskilt vid tillverkning av metallkomponenter. Ett antal olika AM-tekniker vid tillverkningen av olika typer av metallkomponenter har studerats och kommersialiserats.De flesta av dessa AM-tekniker är dyra och mindre tillgängliga, i jämförelse med Selective Laser Melting vid tillverkningen av en komponent i rostfritt stål 316L. Syftet med detta examensarbete är att introducera en innovativ AM-teknik som fokuserar på materialsträngsprutningsbaserad 3D-printingprocess för att skapa ekomponent i rostfritt stål 316Lkomponent med ett metallpolymerkompositfilament. Ett prov bestående av rostfritt stål skrevs ut med en FDM-baserad 3D-skrivare laddad med filament av polymer och metal, följt av industriell avdrivnings-och sintringsprocess. Provet studerades för att förstå materialegenskaperna och dess beteende under efterbehandlingsmetoden. Dessutom genomfördes också resultat från avdrivning och sintring på provet och en jämförelse av provet före och efter avdrivnlngssteget. Metallpolymertrådar för 3D-printing kan vara ett alternativt sätt att tillverka AM-metallkomponenter.
