Remotely Accessible Laboratory for Rapid Prototyping
The Rapid Prototyping (RP) Laboratory1 was established in Fall 2003 and funded by the National Science Foundation DUE 0311586 grant and Tennessee Tech University (TTU) matching support. Since this time, almost 500 high school students and student(s) studying computer aided design/computer numerical control have practiced with RP technology. In order to further extend a remote access capability to this current laboratory and let more engineering and technology students learn this technology via online materials, a new NSF grant was awarded in Summer 20062. Since this time, the remote RP laboratory development has been in progress. Workshops for Pre-K16 (P16) teachers have been organized for the dissemination of RP and this project. A project website3 has also been developed and feedback collected via an online poll. The scope and current development of the project will be reported in this paper.
RP is expressed as a group of techniques used to quickly produce a scale model of a part using 3D computer aided design (CAD) data. The methodology behind the RP process is an additive technology which builds the parts layer by layer. RP was first developed in the late 1980’s. Since then various RP techniques have become available in the market.
There are various motivations in implementing RP technology. Foremost, this technology decreases product development times while dramatically lowering costly expenses. Namely, detailed RP models can be used for testing, modeling, visualization, patterning, and analysis.
The basic steps for all RP techniques can be generalized as follows4:
• A CAD model of the target part is constructed, and then converted to an STL file format. • The RP machine processes the STL file by creating sliced layers of the model. • The first layer of the part model is created at the machines. The model is then lowered by the thickness of the next layer and the process is repeated until the completion of the model. • The final RP produced part and its support structures are removed. The surface of the part is then post processed and cleaned.
The extra steps integrated into the current TTU RP laboratory to make it remotely accessible are
• To develop an accessing interface to view the lab live. • To set up webcams so that students feel like they work in a real RP lab environment. • To establish some scheduling tools so that students can identify their part submission and delivery dates online. • To form some kind of communication mechanisms to communicate to the lab staff. • To deliver the RP produced part back to student on-time.
