Midterm Project Progress
Continue working on your midterm protoype and follow the timeline as outlined on this page.
If you are using the 3D printer or laser cutter for your work, be sure to submit your files as early as possible to ensure it gets printer/cut in time for your deadlines.
Progress check-in is due by beginning of class on October 14th.
Assignment #5: Design a Keychain
Design a keychain for your keys to be 3D printed. Your design must fit within 45x45x20mm and have an opening to connect a key ring. The design is to be developed in Fusion 360.
Note: Do not produce an object that looks similar to the part in the examples below as it was not designed to be a keychain. It is just an example of how to use the software.
To submit your keychain, you will need to use the slicing program Cura and generate the a G-code file to send to the printer.
To set up Cura for use with our printer on campus, follow the instructions below:.
-Download Ultimaker Cura from here.
-After installing Cura, open the program and click through the Getting Started screens. When it asks you to "Sign in to the Ultimaker platform," choose Skip.
-On the Add Printer screen, click "Add a non-networked printer" and select the Ultimaker S3. Then click Next.
-Press Skip on the Whats New screen and finish up by pressing Done.
To prepare a file you've designed in Fusion 360 for slicing, follow these instructions:
-Within Fusion 360, select the body you want to send to the 3D printer.
-Under the Tools menu, click on the Make button.
-Deselect the checkbox that says "Send to 3D Print Utility" and make sure the other settings look similar to below.
-Save the .STL file for your model somewhere on your computer where you can access it later. Name your file "A5_[name]_Keychain.STL"
To slice a .STL file for printing, follow these instructions:
-Open up Cura and drag your .STL file into the main window.
-Make sure to rotate and orient your model to the best printing orientation. This is dependent on your design.
-Ensure AA0.4 print core is selected and the material is any color of Ultimaker PLA. For this assignment, we will use whatever color is installed within the printer to lower the time requirement for the operator. In the future, you can specify a color based on our stock.
-Under Print Settings, select the 0.2 Default print profile and check/uncheck Support if needed. For this print, we will only be using Extruder 1 so if you enable Support, make sure Extruder 1 is selected. In the future, you can use Extruder 2 with PVA soluble support.
-Press Slice.
-Click on the Preview tab at the top and ensure the slice looks appropriate. Take a look at the time estimate as well and see if it is reasonable. For example, multi-hour prints are likely not possible at this time.
-If the preview looks good, press Save to Disk and save the sliced model as a .UFP file. Name your file "A5_[name]_Keychain.UFP".
Send both your .STL and sliced .UFP files to me over DM on Slack before the beginning of class on 10/14.
