This paper describes the Bricklayer Ecosystem – a freely-available online educational ecosystem created for people of all ages and coding backgrounds. Bricklayer is designed in accordance with a “low-threshold infinite ceiling” philosophy and has been successfully used to teach coding to primary school students, middle school students, university freshmen, and in-service secondary math teachers...

Facial reconstruction using 3-D computer graphics is being used in our institute as a routine procedure in forensic cases as well as for skulls of historical and archaeological interest. Skull and facial data from living subjects is acquired using an optical laser scanning system. For the production of the reconstructed image, we employ facial reconstruction software which is constructed using ...

In this paper, the application of Rapid Prototyping in fabricating non-assembly robotic systems is presented. Using the Stereolithography Apparatus SLA 190 of the Department of Mechanical and Aerospace Engineering of Rutgers University, and the Selective Laser Sintering Sinterstation 2000 of DTM Corporation of Austin, TX, prototypes of mechanical joints were fabricated experimentally. The desig...

A process for customized implants, that minimizes bone removal while maximizing the fit and the “usability” of the implant, is developed. The process involves integrating technologies of Computed Tomography (CT), image processing, stereolithography, finite element analysis (FEA), and investment casting in the design and fabrication of a near optimal fit between the patient’s bone and the implan...

In this paper, the application of Rapid Prototyping in fabricating non-assembly robotic systems with inserts is presented. Previous work demonstrated the use of the Rapid Prototype Stereolithography and Selective Laser Sintering techniques to fabricate prototypes of mechanical mobile joints. As examples of their applicability, the joint designs were then used to fabricate complex multi-articula...

In this paper we present the world’s first micropump entirely fabricated using a 3D direct manufacture process based on microstereolithography. The device employs a single pneumatically actuated membrane, with flow rectification provided by a nozzle/diffuser arrangement. A maximum flow rate of just over 2,000 μl/min was achieved with a pneumatic pressure of 2 PSIG and a stroke rate of 96 Hz. Th...

Stereolithography (SL) technology is the mostly widely used Rapid Prototyping (RP) process in which complex structures are fabricated in a layer-bylayer fashion. Currently Microstereolithography (MSL) is undergoing fast development. In this paper, the development of MSL and its application in micromanufacturing are reviewed. One promising direction for the development of MSL is the assembly-fre...

The benefits of the integration of novel optofluidic elements, e.g., fluidic lenses and liquid-core / liquid-cladding (L2) waveguides, for on-chip optical sample analysis are discussed. Using properly designed microfluidic channels, pre-calculated flow rate ratios and transparent fluids with different refractive indices but similar viscosity novel fluidic optical elements can be created. In thi...
