Topic: Printing rc car body from free 3d file

Dear All Master,

i'm from Jakarta, Indonesia i have 3d printing machine on my office and i have a hobby remote control car.

i'm already try to print rc car body from free source 3d file for example from grabcad or google warehouse

what i'm doing is delete the wheel and all material under the body, because i just wanna print the body for put on my rc car.

but what i get when i printed that file the file is not printed like the design (i'm attach the printing result)

can you help me for this problems?

sorry for newbie asking sad

Re: Printing rc car body from free 3d file

The problem with your model is that it's just a skin.  It's not a closed mesh, and there are hundreds of holes in it.  Closing the holes is not a problem, however, turning this into a manifold, watertight model is almost impossible.

To print or, 3D print, that is the question...

Hi Pirvan,

thanks for your helping, do you have suggestion for the software that can i use for turning into a manifold that easy and still printing like the model?

I hate to admit it, but this model had me beat.  I spent nearly 3 hours on it, and still couldn't get it to work. 

First I loaded it into NetFabb, which closed all the holes, but at the same time filled in all the wrong spots.  Then I manually filled the holes to make it a solid body.  The idea would be to print it with 2-3 layer walls and supports, so it would print hollow with supports only for the ceilings.  Problem was that it still has many errors, and neither Slic3r nor Kisslicer can handle the model due to the errors.

Then I loaded it into MeshMixer.  I tried to use it's extrude function to give the skin thickness.  The problems is that this model is made up of multiple meshes, so it only thickened some parts, not others.

Next up MeshLab.  I was able to make it manifold, but I can't Boolean (join) the meshes.  Every time I try it crashes, because there are like 214 separate meshes in it.  I tried to slice the model anyway, but no joy.  Different errors, weird slice with missing parts.

So at the moment, I put it aside.  I might give it a go at a later time, but for now, I'm conceding defeat.

FWIW, I can tell what you want this for, as I'm a MiniZ fan myself.  Your model is full size (the size of the real car), so it needs to be scaled down to about 1:27.  Unfortunately, MiniZ's are not scaled down exactly, the 1:27 scale is approximate,  so you'll have to measure your chassis wheelbase, and use that measurement to scale the model down (center to center of wheel wells).  You'll also have to make the body clips and the nose clip socket.


P.S.  Do you have the original model?  It was probably something like a .3DS or a .max file.  Maybe if I load it back into the original program it can export it more cleanly.

Hi Pirvan, exactly i wanna put it for my lovely micro rc 1:28 or 1:27. and you right that's the full size because i grab from sketchtup or gradbcad, may be you can try to download any kind of model on there the file is to big almost 45mb for .3ds

Yesterday after i post reply to you i'm already try meshlab & netfab like you said, and always crash...

or maybe you have any suggestion for creating the minirc body for 3d printing so i can try to creating, because yesterday until now i'm always stuck with editing model from skethcup & grabcad sad

Note : on behalf of my self sorry for bothering you to spend 3 hours for checking the file

Salam,
from Jakarta Indonesia

Re: Printing rc car body from free 3d file

Update:

THis weekend I had a little extra time to fool around with the car model.  I was able to reconstruct the mesh, however a lot of the original detail sharpness is no longer there.  On  the other hand, I don't thin a Solidoodle could have printed that detail at this scale anyway, and the overall body shape is there.

Unfortunately, the remeshing process also generated 1.5 million faces, so I had simplify/reduce the mesh size dramatically in order to get it down to something "reasonable", in this case 18.4MB.  Of course, even more detail was lost in this process, but it's not all that bad.

Here is a link where you can download the STL file (It's zipped up to get it down to 9MB).

You should be aware that slicing this file will take some time, on my Core i7 machine it took 24 minutes to slice the file @ .1mm without any support.  Turning support on, will probably increase the slicing time.

Good luck with your print, and post some pics of your printed (and painted) model.
