Is it a good idea to 3d print out the frame and base of my battery buggy?

It might be too heavy but it's worth a try! Make sure the infill is set low though. (10 to 15%)

If you were to 3D print the chassis or frame of a battery buggy, I would suggest not covering the entire bottom of the chassis and only covering half or a third of the bottom. So have something like the picture below. Leave the red area empty. This will decrease the weight a lot. Or maybe try 3D printing a chassis that is somewhat like an F1 car or a capital i. Then have the motor, batteries, and other components in the center of the vehicle. Hope this helps!!!

Or print only components that are used to join other parts like dowels.

Carbon fiber rods are included in dowels. I've left the choice of material up to the user. Aluminum, steel, plastic, carbon fiber, basswood, balsa wood, K'nex, etc.

I would not recommend 3D printing the buggy, as the plastic can be quite brittle. If you were to, it would be quite heavy as a solid piece. To counter it, you would have to implement a hollow design with necessary supports, but that will be tricky to design and print.

I have done Scrambler, a 2016-2017 event, and used Actobotics parts from Servo City to make the structure. The weight came in at about 1000g, way to heavy. Now doing Battery Buggy this year, I salvaged my Scrambler car and replaced heavy aluminum parts with half as light PETG 3d printed parts made by my very new 3d Printer. You can find these part's STEP files on the Servo City website by finding the part you want and clicking the RECOURCES tab. Also, if you don't have a 3d printer and are using Actobotics, make the car lighter by using Mini Channel on the Servo City website.

Did you try PLA? Isn't it risky to use petg since it's flexible? Also, what did your mass come out to following this alteration?

PLA is definetly better than ABS or PETG. It's easier to print and alot stronger.
