Why F1 Engines are Built with Sand

Sand printing is similar to 3D printing; layers of 0.25mm thick sand are ‘printed’ onto a jobbox with a layer of chemical binder in between allowing for complex 3D shapes to be made, slice by slice, layer by layer. It's so good that F1, LMP1, LMP2, WRC, WRX and Moto GP use this tech to make all sorts of parts. So how does it work and is it the way of the future?

    Bonus - The most powerfull F1 engine ever was "cured" with urine. The BMW M12/13 of 1986 produced an estimated 1400bhp as a 1.5l turbo and was created from used BMW M10 road car engines. These were then left outside in the elements for months and as legend has it, urinated on which might have had some nitriding effect on the ferrous metals.

    7:44 -- A little correction.. the sand doesn't want to expand 1%. Molten aluminium occupies a volume ~1% bigger than when in a solid state so as the metal cools it contracts by 1% from the shape defined by the mould. Been dealing with this for 20-odd years and have designed thousands of moulds including 3d printed cores.

    Your explanation is exactly 100% wrong. 2 mm thermostat is not 10x0,2mm sand. Also, not 20x 0,1mm = WRONG!!! You must make the outside of the thermostat in the sand, not the material wanted to remain. It is negative moulding not positive.

    Nice video, good basic explanations. I addition to bottom up, you might mention that for some years now high stress parts casting has been done under vacuum to reduce gaps and contamination of the crystal structure. This allows for greater strength and lighter weight since the parts can use less material.

    Um.... No F1 Engine maker is going to 3d print a sand casting for a part lol...... If anything they will Print the part over and over and test fit it till they get what they want to use from a laser cured Light Reisen printer. Extremely high resolution vs sand casting Garbage casting lol.... Then they put the 3d printed model in a silica ceramic mix and shake it for about 2 hours release all the air and let it dry. They heat the mold up after and bake it for a few hours to cure it and in the process the 3d printed model is now turned to dust and your ready to cast a part with perfect dimensions. It's How they do most race engines casted part. Maybe 20 years ago when they invented Sand casting printers this was high tech... No one uses sand anymore to much that gets stuck in the mix and causes metal imperfections.

    HOURS PER GALLON. Never liked MPG, it didn't make sense when I was sitting in bumper to bumper traffic in Seattle. Some weeks I would get 0 (zero) miles per gallon, while waiting in traffic, then calling the Tow truck because my 35mpg car was out of gas. Totally made sense when I rented a tractor for the weekend, and it clocked Hours used, which could be calculated out to Hours per gallon of diesel. Why don't cars do this??

    This was actually entertaining, was hoping to see a little more discovery Channel footage, ie the actual process in real life, not an animation, but still really good way of explaining it. Would you be able to, say, build a model big enough to manufacture large containers vessel parts for sea? And I know some metals/alloys need to go through different or multiple processes to make it stronger so how would that work with sand molds?

    Instead of flipping the image making the video black and white and then inverting the black and white would be better. To represent the sandcast mold. I figured you were talking about the part not needing draft as well as being able to get away with different if not lower core strength because you don't have to assemble the cores. My metallurgy isn't good enough because then I would know if they use nitrogen in the sand casting to avoid ceramic creation.
