With SOLIDWORKS and 3D Printing, Graphics Systems was able to design and print a full-size replica of the Lombardi Trophy!
The Super Bowl is upon us! It all comes down to Denver and Carolina. Who is going to win it all?
Although I'm still getting over the fact that Green Bay's season is over, it's an exciting time. It's the biggest game of the year and the best team will win the coveted Lombardi Trophy.
In the spirit of the game, we decided to model a replica and have it 3D printed! Here's how it went.
Everything starts with a sketch! I opted to start with the base of the trophy. We used a drawing to gather all of the necessary dimensions ahead of time.
Then, I created another sketch offset at about 19 inches to give us the second profile necessary for our lofted stand.
Then I created a loft using those two profiles, and we now have our stand. Ta-da!
Now it's time for the ball. We'll need to start with the general shape, cut a groove for the seams, and add the laces.
We'll start by sketching a profile that gives us the shape of the football.
Upon revolving that sketch, we now have our ball, and can begin finalizing the design. Since we intend on 3D printing the model, it's important for our purposes that the ball be separate from the stand, so we will leave "Merge Result" unchecked.
Now we are going to make adding the laces a bit easier. Since we will be adding them after the seams are cut, it will be nice to have a surface representative of the face pre-seams. I am going to do this with the Offset Surface command.
Next we will use a swept cut to create our seams. I've created a profile that will cut a rounded groove into the ball, and will use a copy of our original revolve sketch for the path.
Now we can pattern those cuts around the ball using a Circular Pattern set to 4 instances, equally spaced.
Now that our seams are in the ball, we are ready to cut the stand to match the bottom of the ball. In order to do this, I will use the Indent feature. This is better than Combine in my case, as it allows me to keep both bodies. I will select the stand as my target body, and a face of the ball as a surface to cut. Then by checking the "Cut" option, it will cut the stand, leaving me with two separate bodies.
Now it's time to add some laces. (Pointing outward, Dan Marino) I'll use a Boss-Extrude with the Up to Surface end condition. For the surface to select we will use the surface we created earlier with our Surface Offset
Lastly, we will add some fillets to round off the sharp edges, and we'll be ready to print!
Bonus Render in SOLIDWORKS Visualize:
Both the base and the ball were printed on the Fortus 250mc. The base was printed in 2 pieces and then glued together using a plastic welder. Both the base and ball were sanded and smoothed in preparation for the chrome dip.
Once they were sanded, the ball was glued to the stand and then sent to Coat of Chrome! The finished product is coated with a silver metal deposition with a mirror finish. The final product turned out so great that it has actually been difficult to get a good picture of it without being in the shot!
And that's it! Enjoy the game, and equally important, all the hilarious commercials!
