Developing A Measurement System To Assess Line Profile Retention In 3d Printing, Heng Li
Developing A Measurement System To Assess Line Profile Retention In 3d Printing, Heng Li
Theses
Manufacturing three-dimensional (3D) objects with methods adapted from conventional digital printing have propelled the development of additive manufacturing. In this process, the printing devices directly deposit or fuse materials to form 3D solid objects in a layer-by-layer fashion, thereby creating the additive approach of fabrication.
As additive manufacturing (AM) has been increasingly adopted for rapid prototyping and part manufacturing, the need to determine the part quality which results from the processes becomes crucial (Monzón, Ortega, Martínez, & Ortega, 2015). There is a lack of quantifiable measurement systems to define a printer’s ability to resolve systematic and geometric features and dimensionalities …
A Multi-Channel 3d-Printed Bioreactor For Evaluation Of Growth And Production In The Microalga Dunaliella Sp, Cristian A. Cox
A Multi-Channel 3d-Printed Bioreactor For Evaluation Of Growth And Production In The Microalga Dunaliella Sp, Cristian A. Cox
Electronic Theses and Dissertations
We explored the capabilities of additive manufacturing using a photo-cured jetted material 3D printer to manufacture a milli-microfluidic device with direct application in microalgae Dunaliella sp growth and intracellular compounds biosynthesis tests. A continuous microbioreactor for microalgae culture was CAD designed and successfully built in 1 hour and 49 minutes using black photopolymer cured by UV and a support material. The microreactor was made up of 2 parts including the bioreactor itself and a microchannel network for culture media fluids and microalgae. Both parts were assembled to form a single unit. Additional optical and auxiliar components were added. An external …
3d Printing And Healthcare: Will Laws, Lawyers, And Companies Stand In The Way Of Patient Care?, Evan R. Youngstrom
3d Printing And Healthcare: Will Laws, Lawyers, And Companies Stand In The Way Of Patient Care?, Evan R. Youngstrom
Pace Intellectual Property, Sports & Entertainment Law Forum
Today, our society is on a precipice of significant advancement in healthcare because 3D printing will usher in the next generation of medicine. The next generation will be driven by customization, which will allow doctors to replace limbs and individualize drugs. However, the next generation will be without large pharmaceutical companies and their justifications for strong intellectual property rights. However, the current patent system (which is underpinned by a social tradeoff made from property incentives) is not flexible enough to cope with 3D printing’s rapid development. Very soon, the social tradeoff will no longer benefit society, so it must be …

3d Printed Bone Supplement Materials, Azem Khalifa Yahamed
Dissertations
Three-dimensional (3D) printing is an advanced rapid technology that can be used to make human bone substitutes with exact shape and designed structures, based on models created from actual individual bone medical Digital Imaging and Communications in Medicine (DICOM) images. Biocompatible polymers have been selected for 3D printing of human bone structures. The thermoplastics were 3D printed with Fused Deposition Modeling (FDM) are Acrylate Butadiene Styrene (ABS), Polylactic Acid (PLA) and ULTEM 9085 (a polyetherimide). The polyamide PA 2200 was 3D printed using Selective Laser Sintering (SLS). Digital ABS (a crosslinked acrylic polymer) was 3D printed using PolyJet Technology. These …
