Race Day

The Race

After we 3-D printed the cars, we took them off the printers, and began working on the post processing of the car (see below). We assembled the wheels, axles, and washers onto our cars. There were three different categories of races: all thin tires, all fat tires (my race), and combo (fat and thin). We then had to put the guideline through the guideline holes of our cars to keep them on the track. It was a 60ft track in which we had 5 seconds to get across the finish line or be disqualified. We then had to put our times in a spreadsheet to record the times.

Different angled images of the 3-D printed co2 car. The post processing of this car included: removal of supports, sanding of body, addition of washer, wheels, and axle. The axle had to be cut down to size for the front and back tires. Also had to cut pieces of straw to accommodate for the oversized axle holes.

Speed/Time:

My first, second, and third times were 1.807 seconds, 1.521 seconds, and 1.513 seconds respectively. Therefore my average time was 1.614 seconds. My maximum velocity is shown and calculated below. I also believe I got 5th overall for the races.
