Making progress on my build...

That is VERY cool.
Laser welding, 3D scanning, and 3D printing are all areas I have really wanted to get into but just haven't.

Hit me up if you want to have a conversation about 3D printing. I've been 3D printing car parts since 2009.

A 3D scanner is the #2 item on my list of things to buy (after a new ECU for my 818) once I sell my current project. Mind sharing a little bit about why you picked that specific one?

This is still a "consumer" grade scanner, although it's on the higher end. Not professional by any means ($15k +++). The $1k consumer scanners do ok for larger objects (6"+) but fall on their face scanning smaller parts/objects. Some of the brands rely on kickstarter purchases then the business model is to release a new model immediately. These don't perform very well at all. Anything under $1k seems to be junk unfortunately. You can probably get away with a $1k scanner. Shining 3D is a reputable company that makes $25k+ scanners and the cheaper scanners like the one I bought benefit from the software development of the "big boys". Software is a major contributing factor to a quality scan.

I've been printing for about the same amount of time. Always something new to learn, I appreciate any help I can get!

I was directing my comment towards Crash, you certainly have a lot of experience with the craft. It is crazy how far it has come, I just found my first 3d printer a few weeks ago tucked away. Sanding drums for gears and shoestrings for belts.

I had been eyeing this one. CoachBuilt on Youtube was getting really good scans of engine pieces with it:

Looks like what you bought is the next model up.

Just started playing around, very impressed with the capabilities, and very easy to use.

Quick scan of the front bumper to see how it does with larger scans. It's still fairly rough with exposed body filler. Scanner didn't reliably see the edge of the fairly glossy hood, so I applied some scan spray which disappears after a few hours. Plenty of data here to mod the fascia.
FYI these are 0.5mm resolution scans.
Another large gif file in this post.

Very cool!!

[Shoeless]

That's awesome!!!

In a prior life, we had to use a similar spray when we white light scanned parts for dimensional evaluation. These were machined F-135 engine parts for the afterburner section of the engine. Ridiculously tight tolerances and basically needed this method of inspection to prove every single point on a machined surface met the profile tolerances. Insane in that you needed basically a mini super computer to handle the amount of data it captured in about a 5 second scan.

Life has been very busy with kids sports. Working with a 3D mesh, I have had to switch CAD software. I was using designspark mechanical, which I really like. But it seems like everybody is moving to Fusion 360. Little bit of a learning curve, working with forms, surfaces, t-spines etc is completely different than what I'm used to which was basically creating drawings, then extruding, then filleting, etc.
So import the mesh into Fusion. Create a surface which matches the mesh. Create the surface shape of the part. Thicken and export as STL. Divide the part so it fits on the printer. Print and reassemble.
I'm leaning towards this style of intake vs the previous fancy design. I think this will scoop more air with less drag.
I'm going to redesign the front angle to point towards the corner of the rear hatch, like I marked in the attached photo, to better tie into the lines of the car.
Three gif's attached.
Thoughts?

Thoughts?

I'm not qualified to talk about how this will collect air versus the lambo design, but I agree it fits much better with the curves of the car. it's not too dissimilar to what I arrived at for my 818:

I like that you filled in behind the door frame. Cleans that up nicely. Not so sure about the angled scoop. I think a bigger picture view would maybe give a better idea of how it fits and flows with the rest of the body.

Roof scoops are along these same lines. What fits and works is one thing, and what actually looks good is another. I have seen plenty of functional roof scoops on prototype cars that I am sure work perfectly well, but IMHO, ruin the side view of the car's lines.

[beeman]

Mike-
I angled the scoop because every airflow/CFD analysis I've seen on a moving car shows air crashing down off the roof to the side of the car. I think that an angled scoop will more efficiently capture that air. Perhaps I should parallel the b-pillar angle for better aesthetics? What do you think?

[crash]

Obviously if you run with your roof off it won't matter much, but I think you should at least mock it up with the same angle as the B pillar. I would just put some cardboard in there and paint it black and see how it looks from different angles while you move around. I believe in prioritizing function, but form is also super important in cars like ours.

[lance corsi]

I made a similar pair of scoops for my 818 but after I put them into place, I didn’t like the look. Mine parallel the B-pillar and bow outward to form a scoop. Mine are acrylic and allow a view of the candy store.
