19. Draw a 500 unit horizontal LINE starting on the very bottom sloped line. 20. Click the portion of the vertical line nearest to the circle previously labeled A. 21. EXPLODE and select this line again. 22. OFFSET this line 500 um to the left a. Type OFFSET b. 500 c. then click on the left side 23. EXTEND this line down to the bottom a. Type EXTEND b. Select where you want to extend to (the line you drew in step 19) c. Click on the line you want to extend (the line you made in step 21) Your main device is DONE! This is where you have 2 choices on how to proceed, for COMSOL modeling or for mask production. When first designing a device you should do COMSOL modeling to make sure you have the right dimensions and types of flows for your needs. After perfecting your design (multiple iterations of AutoCAD/COMSOL models) you will be ready for mask production. These two avenues have different requirements for the end AutoCAD product. Thus make a saved archive copy of the AutoCAD file you are currently using so you can go back to it in the future. COMSOL Production Requirements: 1. Clean AutoCAD device – no extraneous lines, completely closed regions, 2. Different areas the of the device that will be at different heights will need to be: a. Completely separate closed objects b. On different layers labeled well enough to know the object/height by reading just the layer name UConn - Dr. Shor’s Engineered Microhabitats Group Page 6
Customization for COMSOL Since the big circle at the top will actually be a tall punch through the PDMS and the other parts of the device are only 50 microns tall we will have to separate them into different objects and then into different layers. 1. Go back to the top of the device near the circle. 2. Create an arc with the same radius of curvature as the circle between the two vertical lines (HINT: ARCs always travel counterclockwise in AutoCAD, don’t ask me why) And yes this will create an arc over the existing part of the circle. You won’t be able to see your arc yet. a. ARC, then click on the top of the left vertical line b. Then type C for center, choose the center of the circle. c. Click on the top of the right vertical line. 3. Type in LAYER 4. Add two layers using the button in the square box in the figure below 5. Make one red named 50 microns and one blue named 10000 microns UConn - Dr. Shor’s Engineered Microhabitats Group Page 7
