3D printed RZ34 Aero Project

[jamesmcintoshjr]

Hey Gang, figured I'd share this as I'm a fair way along with the initial bits I'm designing for the Z. For context I used to have an FK8 that I made a complete aero kit for back during covid, and that worked out so well I'm doing it again for the Z.

The end goal is front lip, front half spoiler, grill garnish w/license plate mount, side skits, rear spats and possibly rear diffuser and a different spoiler. As of now I've designed my grill garnish and it's on the car being tested, and I've tossed a few test prints at the car to check size and the accuracy of the laser scan before I print a complete lip.

I'm quite pleased with the grill garnish, as I was interested in the speed forme one until I saw they wanted almost $1000 CAD, and you need to drop the bumper to install it. My version uses self locating mounts I made that attach from the front similar to the stock license plate frame, and then the garnish "cover" snaps into the mounts. and can be secured with screws or just adhesive for a cleaner look. I also did the license plate frame which lowers the plate to allow more air flow up top and angles the plate downwards to visually shrink it.

Wow...that looks great
what material are you using? How will it hold up to summer heat and cold weather? What about paint prep and longevity?

 

[jamesmcintoshjr]

I typically use PETG which historically has been fine. 5 years of testing with my type R and it held up better than most fiberglass parts. That being said this time I'm going to try ASA which is a very standard plastic you'd find on cars, and temp stable past 100 C. It's basically ABS that is resilient to UV light degradation. Paint prep was just sanding and a good plastic primer and I've had no issues.

One great thing with printed parts is that compared to fiberglass it's very flat. You don't get the waviness you get from composite parts, plus the ductility and impact strength.

Man that looks amazing. Will you be selling these parts. I'd be interested when and if you do. I really like how the bumper flows. Can't wait to see the rest.

I'll be selling the files so you can make your own. I have an etsy store where all my design work lives and can be downloaded - jmjrdesign.etsy.com

Looking forward to your releasing the completed files, now I just either need to learn how to 3D print or find a friend who can do so.

yeah when I release files I make a point to target common home printers, and I usually do 2 versions that are cut up so they can be printed on small and large ones.

I am very interested in that center bar across the grill, somebody sells one but it's over 600 $ shipped.

yeah, speed forme in japan. $660 USD. For me in canada that's near $1000 :S

Mine is a little bit different as it has it bit more shape to it, it tapers top and bottom. I will probably make a few to sell pre-printed for those that do not want to print, and it'll be probably half that price.

In case you were wondering what it looks like in red

my printer is small so yes I would be interested in a pre made one for sure

How small is your printer? There will be a version that can print on the smaller Bambu printers. If you can do PETG you'll be good to go.

 

[alutwon]

its an anycubic kobra 2 max, 500 mm. I've never gotten the thing to print the way I want

 

[jamesmcintoshjr]

Lol that's not a small printer!! My biggest printer is a Bambu h2s, it's only 340x320x340 so you'd be able to print the less segmented version if you can dial your printer in for PETG. An enclosure really helps, even just a big box around it to keep the temps in.
