3D PRINTING CAR PARTS HARDWARE
I originally started with an Ender 3 max neo 3d printer for printing car parts. I’ve since upgraded to an enclosed 3d printer to print with ASA/ABS and put a free 3d printer tool selector together you can use here:

3D PRINTED BMW VENT GAUGE
First up is a cooling vent that also functions as a gauge holder. The model was made by J0Mueller and can be found on Thingiverse.
This model replaces the stock BMW e30 mid sized front dashboard air vent. You can add a turbo gauge or any other gauge for that matter. Multiple vent gauges can be printed
THE 3D MODEL IS A SIMPLE DESIGN THAT’S PERFECT FOR A FIRST PRINT…
🕓 TIME TO PRINT: 4 HOURS
Note: Print speed depends on the 3d printer infill density, infill pattern, and print speed.
3D PRINTED COLD AIR INTAKE
Next is a cold air intake inlet. Our BMW e30 has 4 headlights and this 3d printed part replaces one of the high-beam headlights.
🕓 TIME TO PRINT: 11 HOURS
The air intake inlet is then connected to the intake manifold. The model was made by Johnny379 and can be found here on Thingiverse as well.

3D PRINTED DIGITAL DASHBOARD
The third item on the list is a 3d replica model of a BMW e30 dashboard insert.
The model looks to have been scanned and converted into a 3d file and cost $30 from Tangent Innovation.
This is the largest 3d printed car part we could print on our 11.8”x11.8”x12.6” Ender 3 print bed without splitting up the part.
🕓 TIME TO PRINT: 20 HOURS
But if you need to print bigger car parts take a look at the Bambu Lab H2D. It can 3d print car parts up to 13.77”x12.59”x12.79” in size.
Once 3d printed, an LCD touch screen and Raspberry Pi were added to the 3d printed dashboard. We also plan to swap out the BMW DME ECU to a Speedunio that can interface with the Raspberry Pi to display different digital gauges.
WHAT’S THE BEST FILAMENT FOR CAR PARTS?
Most beginners start with PLA filament because it's easy to print with. However, PLA can’t withstand the weather or the hot sun or wet environments.
PLA will start to warp around 120 F. However, ABS will not melt or sag in direct sunlight. Therefore you’ll want to print car parts with ABS-based filament.
PRO TIP: The downside to ABS is that it's harder to print with, but with a hotter hot end, bed heat, and an enclosure ABS is much easier to print.
There’s also PEGT which has some weather-resistant properties but is said to print more easily than ABS. However, some have mixed results depending on filament selection.
We tested our 3d printed PLA vs PETG vs ABS car parts and here’s the results:
PLA filament started to sag in sunlight after 30 minutes.
PETG filament had no change after more than 1 hour.
ABS filament had no change after more than 1 hour.
For PETG printer settings, Creality has good directions for beginners here.
For ABS settings check out our 3d printing results on a Creality Ender 3 Max Neo here.
BEST 3D PRINTER FOR CAR PARTS
By far one of the easiest 3d printers to use with little to no fussing is any printer from Bambu Lab. The best bang for your buck will be the Bambu Lab P1S. Its print bed comes with a 10.07” x 10.07” x 10.07” print bed size.
