3d Print

Workflow for 3D printer:

1. Make sure the printer is on 2. Download your fusion file, that should be on the engineering shared google drive folder (it should be an stl file) 3. Open cura 4. Hit load model- then load or choose the file you created 5. rotate object to make it lay flat 6. Go to scale to make it smaller (don’t delete values, go like 1.5 then delete 1, because object will delete or disappear if delete scale values) 7. Go to beginner, standard 8. Polybright, under polymaker for material 9. Can press print to brime and support structures. Support structures are used when objects to start start off of the ground, or need support. Brime is used to hold circles in place. 10. Go to control 11. Will give us two motim choices, or two usb choices, which means there is 2 printer choices given. Make sure you choose the right printer, so you don’t cancel someone else’s print. If you here air or move the x or y axies, you can tell which printer you have control over 12. 220 degrees celcius is temperature, bed temperature shoudl be set at 60 degrees celcuis 13. Clean plate off, then use alcohol to make the objects not as hard to get off of the printer

(*Have to get to 220 degrees before extruding pla, or the printer will jam*) 14. Click extrude once it reaches the right temperature, and you want it to come out straight, clean it off with tweesers to make it come out straight and not in a loop

15. Hit print (*Expect print temperature to drop*) 16. turn the printer off you are done using it at the end of the day, or it will ruin the tip of the printer 17. Clean it off in the end

Making the 3D print:

For this project, we had to use Fusion in order to create a 3d object that is a household item. I decided to make a bottle opener because I could customize it and use what skills I have on Fusion to make it. I started off by using the spline tool to make the general shape of the bottle opener. I used the line tool to make straight lines across the top and end and bottom, but added a little curve on the bottom to give it almost like a better angle to position your hand. I created the pointed edges of a bottle opener with the spline tool. I made sure all the lines were connected to make one large shape. I press pulled the shape of the bottle opener 5 mm, to make it 3d. I also used fillets on the back corner to make the bottle opener more rounded. I then wanted to add a smiley face on my bottle opener, and so made a circle and then added on small circle inside the circle, and used a rectangular pattern with a quantity of 2 across to evenly space two of the exact same circles out for eyes. The hardest part of the smiley face was the smile because I originally just made a spline for the smile, but I learned that I could not cut out or extrude or press pull just a spline, so I had to manipulate two splines to make them connect and look like a smile to make one shape, not just two splines. I then press pulled the two eyes and the smile of my smiley face -5 mm, so it would cut through the whole bottle opener. I then press pulled the larger circle of the smiley face -2 mm, so it would be indented, but not cut through all the way. I also, created a curved line in the middle of my bottle opener, but I had to use the spline tool and connect all of the splines together in order to make it work and one shape to manipulate. I made this curve press pull - 2 mm, so it would indent just like the smiley face. I originally tried to create two circles and a spline and use the sweep function to make a curve in the middle of my bottle opener, but it didn't work because it would have to create a whole circle onto of a not very thick object, and it would be awkward onto of the fact that Fusion did not want to do this action, so I used the splines instead. I then saved my design as a stl and put it in my google drive to transfer to the 3d printers.

Printing the 3D print:

I used the 3d printing workflow to print this project.

Summary:

This project helped me remember and refresh my memory on how to use the 3d printers be able to use CAD programs to create 3d designs and prints. I also learned how to use Fusion and connect that CAD software to be able to make 3d prints. If I was to do this project again or had more time to complete this project, I would have probably incorporated more of the skills that I learned in previous projects, that are a little more advanced, that I am not confident in, like making forms or sweeping or manipulating images in Fusion, but I still helped my skills improve on Fusion. I also learned what could or could not be pushed pulled, which will be helpful to know for future projects. This project helped me work on the basics of Fusion, once again, and also work on 3d printers, which are two helpful skills that I can use on future projects.
