Petrol RC Buggy redesigned with VECTARY and 3D printed

Welcome to the era of customization! Thanks to 3D printing, it’s now easier than ever to redesign products of mass production and turn them into something special. Jan Alaksa, a transportation designer, created this Petrol RC Buggy during his very first testing of VECTARY.

Jan shares with us a sneak peek of how the VECT-Buggy was designed.

1. Sketching the RC buggy

Sketching is an important part of the design process. It is practical to have at least a basic idea of how your buggy should look like so you can quickly evaluate layout choices later on.


2. Preparing the RC buggy skeleton

First, I needed a solid base for the new buggy design. I ordered an FS Racing Petrol Radio Controlled Buggy and removed almost all of its original body, keeping only the functional parts. I scanned the bare chassis with a cell phone and imported the model into VECTARY.


3. 3D modeling in VECTARY

This is where the fun began! Although I was modeling with VECTARY for the first time, I got used to the new 3D tool very quickly. What I found great about it, besides the numerous, unique solutions, was the way it combines subdivision modeling and parametric plugins.

Parametric plugins

The use of parametric plugins came in handy when customizing the tires and rims. VECTARY makes that possible with a parametric functionality called “Wheels”. Basically, all I had to do was go to the plugins Library, add the plugin to the scene and then simply move a slider.

For the VECT-BUGGY I printed out all four rims. Printing a tire isn’t really an issue anymore, since you can print using elastic materials, too. The list of plugins offered goes on with Joints & Wires, Mirroring, Revolve or Array, which I find so easy to use and apply. I think it’s what sets VECTARY apart from other 3D tools I used.

4. Exporting and 3D printing

The newly-designed buggy skeleton and its wheels were 3D printed on a Zortrax M 200 3D printer. Since the 3D printer is limited to printing a certain size, I had to cut the models into smaller parts.

I recommend adding little pins and holes (interlocks) to all the small parts you want to print. This makes it a lot easier when combining them, and, in my case, helped keep the buggy together. I exported them as *.obj, because it works with most 3D printers available on the market.

5. Assembling the RC buggy

Seeing a finished product is an incredible motivation for every designer. Prepare to get your hands dirty (or sticky from the glue, if you are a beginner :) I started off by putting together and then gluing the parts. The pins and holes I prepared made it as easy as playing with LEGOs. After that, I sprayed the model with a filler and sanded it until the final model looked just as I wanted. Finally, I sprayed the 3D buggy with three layers of white color and attached it to the original buggy chassis.


6. Buggy’s maiden voyage

For its first ride, I took the buggy to an empty hallway that was just built for a prototyping company ready to move in the building. Driving the 3D printed RC buggy in a space like that felt almost symbolic. I call it destiny. :))
