The parts list located in Appendix C details the complete component quantities needed to assemble the hand structure. The total cost of a spool of ABS and PLA is $62 at the MatterHackers site. The entirety of the structure will consist of 3D printing the hand components as well as the pins that assemble it. Due to the expense of printing ABS, it was decided to print the parts in only PLA. the cost of material became $29 when using 2 readily available spools, while also ordering one to finish the printing. Material was bought through sellers on Amazon.

 

Schedule:

            The scheduling of this project is reliant on being able to produce the structure of a prosthetic hand that can interface with the actuation components and reach completion within the time frame of presentation.

 

           The time constraint for the prosthetic hand is the limitation imposed by the capstone course. The project must be completed by the spring quarter for presentation purposes. The schedule for this project is shown in Appendix E. The schedule is detailed along with the Gantt chart in that Appendix. The tasks and milestones are reiterated there as well.

 

           Tasks associated with the project include the test fitting of base components. Which will be printed by 1-3-19 and assembled by 1-6-19. The task that follows base assembly is the refining of the actuation and fitment of those components. That task will begin on 1-6-19 and end on 1-27-19 with a fluidly actuating hand. The final task will be the refining of the material quantity in order to further optimize the design. Expected time spent on these tasks will accrue to 12 hours a week at a total hour count of 120 hours by the end of the build process.

           Milestones associated with these tasks are as follows:

• First assembly of hand components

• Initial beginning of interfacing the components

• Finished motion of hand

• Optimization of material use
