Project Timeline

It was necessary to identify when each task within the project must have been completed in order to move on to the following subsequent task to complete the specific goal of of creating the artificial Pulmonary heart valve in the ten week time frame.  It was realized that the initial project timeline was slightly more ambitious than the actual timeline used to complete the tasks.  Based on the proposed model from from Week 1, the timeline stays true up until week 4.  During weeks 1 and 2 the group identified to create an artificial Pulmonary heart valve.  This carried through and proceeding into Week two, the group began to work on the Creo Parametric design of the valve.  There were several difficulties involved with designing the valve, including calculating the major definitions of the valve including, average diameter, thickness, and bileaflet design.  Initially, the original design process was only planned to take two weeks, with the group expecting its first prototype design by the end of week three.  However, this process took slightly longer than expected, submitting the first prototype design during week five.  The group received its first design back in week 6, however the designs turned out to be smaller than the accuracy of the 3D printer capabilities.  Fixing this problem, the group enlarged the whole valve design by 10 times the original size and resubmitted the design to print again.  The group should be receiving the altered design in week 7.  

Originally, one of the aspects of the Artificially Designed Pulmonary Heart Valve project was simulating the Creo Parametric design on an online software system, such as MATLAB Simulink.  The simulation was supposed to take place during weeks two and three upon the completion of the online design.  The group reached out to several software companies, Drexel University software databases, and eventually MATLAB Simulink.  The MATLAB Simulink software has many capabilities including simulating blood flow through the heart valve, measuring continuous-time systems, and providing organized results of simulation results.  The group was not able to receive this online software because the MATLAB did not approve the selection to give access to the group for the Student Edition of Simulink.  So far, there has been no other simulation software the group has encountered, that provides the same in-depth simulation results as MATLAB Simulink.  

Moving into week seven, the ammended valve should be printed out, and the group will be able to construct its multiple parts together.  Testing will then take up a large portion of the next 4 weeks, simply as there are many facotrs and stipulations to consider when creating the end result pulmonary heart valve.  The testing will encompass applying force to simulate blood flow and observe how the valve reacts.  Testing will occur between weeks seven and nine.  During this time, any and all errors will be corrected.  

After testing has begun, the group will begin the final report of this project.  The pre-final report has been started in week six and will continue to be revised and new information will be added to create the final report due in week ten.  There will be many parts of the final report that will be able to be completed in week seven, such as design process and materials list, however, the final specifications of the testing and durability will be completed in weeks eight through ten.
