MSD P16512 - Simple Ink Jetting Station Detailed Design Review 12/10/2015

Risk Assessment Added: ● Team Meetings next semester - rank 9 ○ New schedules next semester ○ Will be more difficult to meet as a team frequently

X-axis from Igus ● Place order at end of this semester or start of next semester ● Purchasing Procedures ○ Should team follow standard MSD purchasing procedure?

X-axis - Visual of Scanning Length

Y-axis - Feasibility Test ● The y-axis from the P14551 Senior Design project ● Wanted to ensure that the axes could ○ Handle the weight they are expected support ○ Operate with the required accuracy ● Y-axis passed Feasibility Test and we utilize it in our system ● However the motion bed has some play in it and the team plans to add reinforcements to make the axis more robust

Y & Z CAD ● The pitch of the Z axis lead screw was 2 millimeters / revolution ● The pitch of Y axis lead screw was 3 millimeters / revolution ● The motors driving the system are capable of 200 steps per revolution ● However, since these motors can microstep, the aforementioned limitation is more than compensated for

Y & Z axes (contd.) Side View Back View

Encoders ● Will utilize a linear encoder on the X-axis ● Motor on the Y & Z axes have rotary encoder built in ● HEDS-97X series Digital Output Small Optical Encoder ● Heidenhain Position read out ● Image Loader Board Software

Schematics

Print Head Tubing

Bucket Reservoir ● Bucket reservoir and top fill plate are no longer required with the syringe/tubing system ○ Both replaced with standoffs ● Syringes can be clipped to these standoffs

Print Head Mounting

UV Protecting glasses ● $ 19.95/pack of 4 ● Includes side shielding ● Order 2 packs of 4

UV Protected tubing ● ~ $10-20/ 10 feet

UV Curing Cost Summary System components: $175.22 Light control circuit: $16.71 UV protecting materials: $73.40 Total: $ 265.33
