"Este coche es la bomba"


"Explosive" car to make Crash Derby more dynamic, dangerous and explosive. 

You can print two versions, monocolour or multicolour, up to you. For multicolour you will need a multi-material printer. 

Both version needs a bit of organic supports in the tail and in the cable exit connexion of one bomb, however are super easy to remove as is super little, there are configured in the multicolour version file.

Monocolour version:


You can use the multicolour file and set it to one colour and remove mmu, and keeping the supports configured. 
Or you can import the stl with all parts joint. Up to you.

As is monocolour, I will recommend using the smaller nozzle possible, I used Prusa 0,25mm to the golden bombcar an the 0.07 detail default profile as a base, increasing the perimeters to 5, enabling organic supports and using 30% gyroid infill. 

This models benefits from slow speeds, lower temperatures and lower layer height, as it has tiny parts than can overheat when printing. However, with 220Cº has been a nice experience, but maybe I will low it to 210Cº if I had to print it again.

Print time with this setting was 6h, and 20g of material.

If you use metallic materials it will seem like a trophy, the photos don't make justice.

Multicolour version.

The showed multicolour version was printed with a normal profile, you can use your standard profile or use Prusa Balanced 0.2mm profile for 0.4mm nozzle. I use 20% gyroid infill, 3 perimeters 5/4 top/bottom layers. 
Please take care of setting purges correctly, as is a little model if you don't set i right you will have colour transmission (as I have).
Is important as well that you have perfectly configured the overhangs config, as the lower part have a step overhang and with good config you don't need extra supports.

Print time was 8h 12min, and 77g of material used.

If i had to print it again, I will lower layer height to 0.15mm, as if benefices a lot the final result of the model.

I share a captures when I use supports for getting the photos results.
