Do you plan to do a release of the 1:12 wing set too??

As it was a first test and just a tool - not a model - I took the cheapest available option, which was Gray PA12 at that point. And you are right. It is incredible rough! I could imagine it might work for a seat.
Thank you for clarifying this matter.
I would say that a resin frame would also do, but I have to admit that I don't have an exact overview of the prices at Shapeways (but in my opinion it was always very expensive).

This endplate looks like a FW14B, right?
May I ask how thin you can make such an endplate?
Basically I see 3 levels:
The lowest level is the one on the inside of the rearwing with the areas where you can attach the various wing elements.
The level in the middle is the one with the whole profile
And the top level only has the details like reinforcement plates or the flap at the tail.
I would assume the level in the middle should be the thickest?
Not quite right, but close. :D
It's the end plate of an FW14 (it's a conversion of an FW13B to FW14).

But to your question.
Yes, there are more or less 3 levels, but they also merge into one another.
I believe the main surface is 0.7mm thick. But you could also try to make it even thinner, the print went without any further problems. Then the pockets for the wing elements are worked out of this area from the inside, about halfway up the main surface - ca. 0.35mm. On the outside, the elevations/reinforcements (as well as the original) are then applied with a variable thickness (I think 0.1-0.2mm). Here, too, you are very flexible in thickness.

The thinnest thing I've printed so far were individual elements (paddels) on a steering wheel with a thickness of 0.2mm. These are also stable and paintable after curing, but certainly not really resilient. Therefore not suitable for a rear wing.

I would therefore see the limit for a rear wing at around 0.5mm, even if the individual elements ultimately contribute to stabilization. But you can certainly try a lot. :wink:

No, I don't really know why.
There is a kit in 1/12, why would anyone need new resin wing elements?
And if someone wanted to make a conversion to the FW14, then of course you can always talk about anything. A rear wing from the 90s is mostly a "simple" thing.

Well guy I had time to read it all, and just can say THANKS!!! :D lots of valuable info and approaches.
So far, I tell you what the situation is (and hopefully it can be a help for absolute newbies). Basically I bought a PC with 3 GHz speed and 8 GB of RAM, I undusted my good old Autodesk 123D and have a kind offer of getting a Sketchup copy.
Two first factors and a few hours of jwork later and I've come uo with these...

There's an Indycar brake disc, a JS11/15 front brake, a 15 inch rim, and a Kobas Rotax 250 bike brembo front brake disc.

123D is reasonably useful for things like those, though it lacks IMHO handy tools to make dimension references. Also looks not much user friendly when it comes to drawing the 2D sketches from which I prefer to start.
MAYBE this just depicts my poor knowledge of the program. I preferred to start with what I already knew I could do. There are a good amount of YouTube tutorials, so I'll take the time to watch them.
Then comes a set of questions I have for the...
NEXT STEP!! :shock: :lol: as some of you have named it. You know, the second half.
I don't really know if, assuming that what I have are "perfect" vectorial geometrical figures, I lose resolution when exporting to a printable" format. I.E., what's the resolution, of the density of triangle mesh my program will use to export it, or if it depends o the progra or not.
As I mentioned earlier, some might come to me with a nice JPEG assuming I can make an excellent decal set with an ALPS, just they don't know how far that is form being usable. So I fear to be in a similar position.
Who knows, as Peter Griffin would say, maybe it all fixes by itself if I do what I want.

Ah, Roman! :lol: a reference to the Seth McFarlane world is always welcome :lol:
Well guys, emanwhile I'll try to see how what I designed is "seen" by meshmixer...
Thanks to all again!!
I loved specially the "how this goes from the start" reports! :D

It is important not to get lost in the details.
You will find that not everything can really be taken over 1:1.
This step usually depends on the scaling - 1/12 certainly allows for more details than 1/20...
What you need is a "good" STL file with no errors in the mesh.

After that you basically get to slicing and printing.

Getting more RAM may be quite easy for that PC too. Can you run the tool on this website (https://www.belarc.com/products/belarc-advisor) and PM me the details? I can let you know what would be compatible.

Thanks Thomas! You nailed it, it has so much detail because it's 1/12th 8) Obviously, if I depict an Allen screw that measures less than a mm, trying to depict the hole is getting really anal! but sure I want to check the boundaries of this thing.
From that point, I don't understand :lol: not sure if I have made a good STL (maybe yo talk about inner holes or something) and let alone the slicing. I think I'll send you thiese files to see if you can check them please! :wink:
Thanks, Stu. I checked the APP, there goes the info.
I think it's DDR3...
All the best and thanks again!

I`m not sure if the printer gets all these details done, some might be to small, even in 1:12, what kind of printer did you bought?
A lot is experience when using the printer, so you have to give it a try to see where problems show up, play around with the direction the part sits on the build plate, some issues can be fixed that way, others might need a reconstruction in CAD cause parts are to small or thin.
Take a stand!

I’m not sure either so the idea is to check the equipment. No I didn’t buy anything yet. It’s my in law making a favor...

looks promising!!
https://i.postimg.cc/2yn9vC0Y/pantallazo-impr.jpg
Maybe not the ideal configuration but didn’t want to cause trouble to my brother in law :D and besides I can check what the results are with the less favorable spec :wink:
Yep surely with all disc shaped stuff in horizontal looks the ideal.
Next time I ask something l’ll check I don’t overbook.
I will show the results tomorrow, so watch this space :D
