Angles in LightPearson, Terry 16 November 2012 (has links)
My work on canvas and in jewelry focuses on the tension between the hard edges of geometric shape and soft lines of organic form. Light plays an important part in the viewing of these opposing forms. It reflects off the shapes and textures creating sharp contrasts and enhancing the individual sections as they relate to the whole. In my paintings, I set organic floral forms against geometric architectural structures. I create texture and contrast by adding digitally enhanced transfers, torn paper, and acrylic putty. In my jewelry, I also set organic forms against geometric shapes, by adding stone, wire, and various types of metal to the raised surfaces. The different textures in both of my focus areas attract and reflect light, allowing the look and character of the piece to change as the light changes.

O uso de bambu e metal clay no design de jóias de arte /Takamitsu, Helen Tatiana. January 2011 (has links)
Orientador: Marco Antonio dos Reis Pereira / Banca: Marizilda dos Santos Menezes / Banca: Antonio Ludovico Beraldo / Resumo: Esta dissertação teve como objetivo desenvolver processos de confecção de Jóias de Arte ecologicamente corretas em bambu e metal clay. Para tanto foram projetados e confeccionados alguns protótipos de jóias com estes materiais, aliando o material renovável bambu e o metal clay, que é proveniente da reciclagem de chapas fotográficas e outros resíduos industriais. Foram confeccionados um anel, uma pulseira e um pingente, com partes de colmos de bambu devidamente secos, da espécie Dendrocalamus giganteus, fornecidos pelo Laboratório de Bambu do Cmpus da UNESP de Bauru, e a Prata metal clay, da marca Mitsubishi materials. As jóias foram produzidas de acordo com o instrumento de análise ecológica de produtos joalheiros. Foram avaliados parâmetros como: custo, tempo de feitio, treinamento, ferramentas e maquinários utilizados, durabilidade da peça e resíduos gerados. No final foram propostas as etapas necessárias para a confecção de jóias em bambu e metal clay, associando o design a processos mais enxutos, eficazes e seguros na produção artesanal destas / Abstract: This study aimed to develop eco-friendly art jewelry in precious metal clay and bamboo. Therefore, it was designed and made some art jewelry prototypes with these materials, combining renewable bamboo material and metal clay that comes from the recycling of photographic plates and others industrials wastes. Initially, a ring, a bracelet and a pendant were made using wastes of dried culms of Dendrocalamus giganteus bamboo and silver metal clay of Mitsubishi materials. The pieces were produced according produced according to the analysis chart of ecological products jewelry. The evaluated parameters were: cost, producing time, necessary training, used tools and machinery, durability and generated waste. As a result, proposals were made for the necessary procedures to make jewerly with bamboo and metal clay, combining design with streamlined, efficient and safe processes to make those pieces / Mestre

Characterization of tensile and hardness properties and microstructure of 3D printed bronze metal clayGolub, Michael January 2017 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Bronze is a popular metal for many important uses. Currently, there are no economical 3D printers that can print Bronze powders. A recent product, Bronze Metal Clay (BMC) has arrived. Additionally, commercial metal 3D printers require laser or electron beam sources, which are expensive and not easily accessible. The objective of this research is to develop a new two-step processing technique to produce 3D printed metallic component. The processing step includes room temperature 3D printing followed by high-temperature sintering. Since no material data exists for this clay, the tensile strength and hardness properties of BMC are compared to wrought counterpart. In this research tests are completed to determine the mechanical properties of Cu89Sn11 Bronze Metal Clay. The author of this thesis compares the physical properties of the same material in two different formats: 3D printed clay and molded clay. Using measured stress-strain curves and derived mechanical properties, including Young's modulus, yield strength, and ultimate tensile strength, the two formats demonstrate inherit differences.
The Ultimate tensile strength for molded BMC and 3D-printed specimens sintered at 960 C was 161.94 MPa and 157 MPa, respectively. A 3D printed specimen which was red at 843 C had 104.32 MPa tensile strength. Factory acquired C90700 specimen had an ultimate stress of 209.29 MPa. The Young's modulus for molded BMC and 3D-printed specimens sintered at 960 C was 36.41 GPa and 37.05 GPa, respectively. The 843 C 3D-printed specimen had a modulus of 22.12 GPa. C90700 had the highest modulus of 76.81 GPa. The Yield stress values for molded BMC and 3D-printed specimens sintered at 960 C was 77.81 MPa and 72.82 MPa, respectively.
The 3D-printed specimen had 46.44 MPa. C90700 specimen had 115.21 MPa. Hand molded specimens had a Rockwell hardness HRB85, while printed samples had a mean of HRB69. Also, molded samples recorded a higher Young's Modulus of 43 GPa vs. 33 GPa for the printed specimens. Both samples were weaker than the wrought Cu88:8Sn11P0:2 which had a 72 GPa. Cu88:8Sn11P0:2 also was a harder material with an HRC45. The property di erence between 3D printed, molded, and wrought samples was explained by examining their micro structures. It shows that 3D printed sample had more pores than the molded one due to printing process. This study demonstrates the flexibility and feasibility of using 3D printing to produce metallic components, without laser or electron beam source.
