Exploring Convergence Of Snake Skin-Inspired Texture Designs And Additive Manufacturing For Mechanical Traction, Catherine Sue Tiner
Exploring Convergence Of Snake Skin-Inspired Texture Designs And Additive Manufacturing For Mechanical Traction, Catherine Sue Tiner
Graduate Theses and Dissertations
This research focuses on the understanding, development, and additive manufacture of a 3D printed snake skin-inspired texture pattern. The design functionalities of snake skin were determined through the study of the snake species Python Regius otherwise known as the ball python. Each scale of a snake has hierarchical texture with hexagonal macro-patterns aligned on the ventral surface of the skin with overriding anisotropic micro textured patterns such as denticulations and fibrils. Using a laser-powder bed fusion (L-PBF) process, 420 stainless steel samples were 3D printed which closely resemble the above described directional texture of natural snake skin. This printed surface …
Design And Process Of 3d-Printed Parts Using Composite Theory, Jordan Garcia
Design And Process Of 3d-Printed Parts Using Composite Theory, Jordan Garcia
Theses and Dissertations--Mechanical Engineering
3D printing is a revolutionary manufacturing method that allows the productions of engineering parts almost directly from modeling software on a computer. With 3D printing technology, future manufacturing could become vastly efficient. However, it is observed that the procedures used in 3D printing differ substantially among the printers and from those used in conventional manufacturing. In this thesis, the mechanical properties of engineering products fabricated by 3D printing were comprehensively evaluated and then compared with those made by conventional manufacturing. Three open-source 3D printers, i.e., the Flash Forge Dreamer, the Tevo Tornado, and the Prusa, were used to fabricate the …
Developing A Commercial Product Using A Consumer Grade 3d Printer, Calvin Smith
Developing A Commercial Product Using A Consumer Grade 3d Printer, Calvin Smith
All Graduate Theses, Dissertations, and Other Capstone Projects
The development of affordable, quality, consumer grade 3D printers has allowed entrepreneurs to develop new products and start small businesses. As the print quality of consumer grade printers has improved entrepreneurs have been able to develop consumer quality products without the traditional expense of mass manufacturing. This change from mass manufacturing to small scale and custom production has allowed for the growth of small businesses. Websites such as www.etsy.com show hundreds of small businesses based on 3D printing, these businesses showcase thousands of products ranging from useful household items to cosplay. This thesis covers the process of a small business …
Developing A Testing Instrument To Evaluate The Performance Of 3d-Printed Body-Powered Prosthetic Hands, Araz Al-Dawoodi
Developing A Testing Instrument To Evaluate The Performance Of 3d-Printed Body-Powered Prosthetic Hands, Araz Al-Dawoodi
All Graduate Theses, Dissertations, and Other Capstone Projects
A 3D printed prosthetic hand is an open source technology that became a good substitution for many products in the market. For many reasons, Low-cost, easy made / easy build. As an open source product, 3D printed prosthetic designs are available to anyone around the world, a good option for young children because they need to have a new prosthetic more frequent until they reach the adulthood age. Most families cannot pay a thousand dollars technology. From the research, it found that that there are not enough studies cover the open source wrist body-powered prosthetic. Other studies covered products used …
Remanufacturing Of Precision Metal Components Using Additive Manufacturing Technology, Xinchang Zhang
Remanufacturing Of Precision Metal Components Using Additive Manufacturing Technology, Xinchang Zhang
Doctoral Dissertations
"Critical metallic components such as jet engine turbine blades and casting die/mold may be damaged after servicing for a period at harsh working environments such as elevated temperature and pressure, impact with foreign objects, wear, corrosion, and fatigue. Additive manufacturing has a promising application for the refurbishment of such high-costly parts by depositing materials at the damaged zone to restore the nominal geometry. However, several issues such as pre-processing of worn parts to assure the repairability, reconstructing the repair volume to generate a repair tool path for material deposition, and inspection of repaired parts are challenging. The current research aims …
