#1 1969 Bardhal Lola T-152 Bobby Unser

[jj66]

As I continue to learn to print in 3d, it seems like the temperature of the resin is important enough, I drew the Lola T-152 from the T-153, changing the nose, tail and engine.





3D printed in 1/43th scale, with the wheels aside, painted with yellow spray, black decals and white lines.

Both of those look GREAT Juanjo...I really like the Bardhal...

[quattro]

WOW!

I keep thinking learning to design for 3d printing has to be worth the effort.
Seeing these confirms it.

And the finished painting and decal work. Superb.

[csl]

They look fantastic!!

[craig]

Fantastic design work!
I just started 3d printing as well. What temperature range do you find works best? So for I've had good luck but I'm concerned once winter returns.

I would love for you to design some cars for me.

Superb work on your models!!!

Can you make this available in 1/25 scale?

Please?

Oh Yea...a 1/25 scale kit would be AWESOME for sure!!

As a 1/43rd collector I snapped up a few of Terry's 3d printed models
and have some neat results from them.
Those were the ones that got me thinking about the future and getting some
of the simpler lesser formula material done I have always wanted.

Saw some Radio controlled and slot car 3d printed bodies up close
then saw these and its all kinda steering me that way but have no clue as yet.

Only just got my head around creating a couple of masters for resin casting
which have come out OK. And I am not even doing the casting!

JJ and Terry.
What software are you chaps designing in?

And JJ. Are you likely to ever share the files or the finished product with anyone who might want one?
Or even post the files on a download site?

1/25th. That would be great but are the print costs prohibitive and would it mean tightening up the
details even more at this bigger scale?

Just trying to understand as much as I can about the process before trying to find the time to commit.

[IndyCarModels]

JJ, what settings are you using plus what program are you using to design your cars.

I found that resin I use (Elegoo ABS-like) works better between 19ºC to 24 ºC. Last winter 80% prints failed because I kept resin outside.

I use Freecad to design. There are many tutorials on Youtube.



I'm thinking of sharing files in a Patreon scheme, but not in the near future.



In terms of details, you can design as many details as you like, regardless of the scale you print, but when you print on a smaller scale, a lot of detail will be lost. I usually design the 1/25 scale, thinking to take into account the thickness of the final parts.


In terms of printing costs, this 1/25 scale Lola T-152 weighs 100 g, the resin costs 40 USD / 1000 g and a basic 3D resin printer is about 250 USD.

Until I’m able to press the print button and all the parts come out perfectly, I don’t think so.

Perhaps you are shooting too high? What is perfect? If I had something I could work with, I would be very happy.

This is amazing!

[Art Laski]

Great work, Juanjo!

[putt]

Just amazing.

[illeagle10]

As usual Juanjo, just outstanding! Love your stuff!

Have you considered separating the suspension into individual pieces (1 set for each wheel)? That's what I've done for easier painting:


For the angled pieces as shown above, I just 'pull' the piece so it is horizontal at the point where it meets the body. Ideally I'd have a recessed surface that the piece sides up to, but I haven't gotten that for on that project.

Printing in 1/43 scale, I prefer to print assembled suspensions, to keep the geometry. I have learned that prints have slight warping that affects fit.



Another advantage is that I apply clearcoat to the entire assembly before painting the metallic parts, which improves the finishing.

I'm making the suggestion because I've done the above approach for 1/43 without problem. Maybe you need to evaluate other parts of your process if you're getting that much warping.
