How to Make Custom Car Emblems
How to create your own emblem and 3D print it. I recently acquired this 3D printer. This was a huge learning experience for me, I did have 3D modeling experience with AutoCAD but zero 3D printing experience. I’ll be sharing my experiences through this video and hopefully it’ll help out others wanting to do the same. A friend of mine requested these emblems for his mom’s car. #bambulab #3dprinting #camaro

Procedure:
With the original emblem, I was able to pull the exterior dimensions so the new emblems could be installed without any issues.
I was lucky enough to find pre-made text online that could be inserted into AutoCAD. However this isn’t as easy as it looks, I wanted to ensure it was all symmetrical and the text does have a tendency to change slightly when zoomed in and out. It took some time to make reference marks.
Next was making a border. At the moment, this is a 2d drawing so there’s no thickness, it’s simply flat and just lines on paper. All the lines that touch are joined together so I can turn each of these shape boxes into a thickness, also known as extruding in AutoCAD.
Now the letters are extruded. I got rid of some of the hard edges, so a radius was used on these. You can set whatever value you’d like as long as it’s able to fit into the various faces of the object. The object was then exported as a lithography file.
I started out with my Windows pc, then switched over to my MacBook as that’s where I have Bambu Lab’s software installed which is called Bambu Studio. I haven’t done much modeling in Bambu Studio, it has a load of options to modify your prints and it’s fairly easy to use.
Once the filament has been loaded into the printer, you can sync the program and then select what colors are applied to each object. When picking colors, you’ll need to make sure the different colors are the same type of plastics. There is a huge range of plastics available for 3D printers, not all printers can print every type of plastic. I have found this specific model does work excellent for a wide variety after months of testing and being an enclosed unit, the specific plastic I picked for this application requires a heated environment.
When printing and learning, I discovered printing a small portion of the emblem was best to determine if it was the correct finish or if there were any issues. For the emblems, my final prints were with ASA which is similar to ABS but has more benefits. It can be painted, UV-resistant, flexible, strong, and impact-resistant.
I can then slice the print which prepares it for printing and then I can send the file to the printer wirelessly.
For this emblem, you can see thicker and thinner areas for the red layer, this means the emblem was warping and not staying flat on the build plate. The build plate is where the part is made. Being ASA, it is prone to warping during the printing so the 3D printer should be warmed up 30 minutes before printing, turn all cooling fans off, and then have a brim applied which is a thin border that holds the part in place but is easily removable once done.
Whichever emblem is picked, it’ll be stuck on with double-faced thin foam tape, it can be purchased in a small roll and cut to size. If you plan on making your own emblems, you can even apply a primer to remove any imperfections and then paint them fully to your desired color.
