We have around a dozen or so printers of various types. I've found the ones that print in ABS to give quite strong models, with acceptable surface finish. They finish is obviously better when cleaned up and finished with some mr surfacer or similar.

Nice. Just need to get the 3D drawing sorted!

Further thinking, I guess the air box could contain longer runners extruded as plastic? I guess I'd need to fasten this air box in a way differently from the TB mounts but technically possible.

Could even be very long and join together as a combined 76mm mouth, like an exhaust header - yeah?

Check out what I'm printing!

Its the start of a full sized spoiler out of translucent PLA plastic. All up I have to print 10 sections, each one around 150mm high and around 11 hours of printing. There will be two ali tubes that run through the holes that will pick up the CNC waterjet support brackets and clamp the 10 sections together. Wickerbill on the trailing edge will be glued on and two endplates will be clamped either side. Should look pretty different being translucent as you can see the honeycomb structure inside.

This piece is my final test piece to check tolerances to the metal support structure and strength.

total weight of the plastic wing will be around 2kg in plastic ($100 in print material)

The wing profile is a custom one but it's based on the APR GT200 wing profile with a slightly different form for less drag and a little less downforce.

I've finished printing all the required parts for my spoiler. A total of 12 section with 3 unique parts. I'm just waiting for the CNC cut aluminium bits to be finished before I can assemble and fit to the car.

I've also modelled a little brake duct converter for the 'R' package front lip and the GV lip. This will fit around the trimmed port at the rear of the bumper and channels the airflow into a 3" duct which will go to an aluminium brake shroud that I'm also getting made. Here are some pics of the prototype 'R' package printed part:

For the GV lip, I modelled this part from photos. Does anyone have one on their car in Perth that I can use to test fit a prototype print?

When 3d printers start to do girlfriends I will be interested.

How much?

Free... I'll put a link to the 3D models on here when they are finished. Alternatively I can print them and mail them out if someone doesn't have access to a printer. I think they weigh around 110grams and take around 5-6 hours each to print. Say $70 a pair to cover materials and time. Shipping on top of that.

You still need brake shrouds and ducting to attach to thems. I'll be getting some shrouds CNC cut for my car at some point that people can use. Alternatively you can buy the Singular Motorsports ducts that you can get off miataroadster or trackspeed.

EDIT: Goodwin not miataroadster

If you are going to get shrouds CNC cut, I'm sure there would be plenty of interest.

I could do a bulk order... problem is they also have to be bent and have the pipework welded to them to attach the ducting too. If I was handy with a welder I'd make them but unfortunately I can't weld ali. So it will be a bit of hassle all up to make them all. Plus this work has already been done: http://www.singularmotorsports.com/product/singular-motorsports-3-inch-brake-ducts/

How much do you think it will cost?

madjak · Postby **madjak** » Fri Feb 27, 2015 6:39 pm

The waterjet or CNC cutting isn't that expensive, especially if your doing a few at a time... I'd guess around $20-30 a side. It's then got to be bent and the 3" tube cut and welded on. I have someone who can do that for me but I can't ask him to do 20 of them! The ducting is a little pricey locally so it might be easier to order a whole stack from somewhere online.

I'm happy for someone to use my CAD and get them made over East. I'll get a few done for the local crew.

Whilst this one is plastic:

This one is not...

yeah I want one of those... what they don't say is how much it costs to print! I wonder if I should send them my ducts and ask for a quote? haha
It's great to see this tech being developed in Australia... this is where we need to move as a country! High tech.
