3d printing software issues

[Gattaiolato]

Hello.
as I said in another post: "I don't feel like I didn't see a thread (?) on the press approach, in the sense of how to set the model for export. being a forum of professionals, before amateurs, I imagine there is a lot of rest on their tricks. but if someone wanted to share. . . "
That's it. yesterday I put myself in front of my model in 3d studio: a plot with cubes and a detailed building, quite rich of small 80cm tall and 30 wide walls.
I exported to stl and as he suggested, sorry ignorance, I do not remember who, I checked the file with "minimagic" which detected various problems in the mesh of the ground and in some walls of the building.
It is not a big surprise I admit, if you have to make renderings the problem is minimal but with the press I guess not.
tell me which software you prefer to work with and how do you solve these problems? especially, if there is, who also realizes architecture plastics, that I think are produced a little peculiar.
Moreover these walls would be a problem to make in a 1:200 scale?
Get the answers! :wink:

Get the answers! :wink:

the services to which I support myself for prototypes m ask for a minimum thickness of 1mm, below which there may be problems .
make two accounts with the reduction factor to see if in your model you have areas that could be under that limit. (e.g. internal walls)

Hello everyone!....1mm!?! look here, performed for a world-famous civil engineering studio, dear mariuss I see you are close, very close to my house, literally, and I did not know you, .... I send you an mp!!!
the particular is a pellet stove auger very close to our house, from whom you know them mariuss!! ! !

the bridge traliccio is run with thicknesses 0.6 and 0.7mm ....just know and experience a little bit with the machines you have, some trick you learn:wink:

But wow! I saw the post in the other 3ad, especially the first model, I don't understand what it is but it seems very complex. the bridge is very remarkable and shows all the usefulness of these technologies.
But... it seems to me to see a surface not perfectly homogeneous or mistaken. . .
In my opinion, however, considerable. and you did it with a size, right?
the original file required a lot of processing before going to print?
you were talking about sketchup, I after years of 3d study discovered the wonders of that program. What does it have for 3d printing?
and in this regard I ask (as usual) if I make a cube, a primitive, the printer full print? If I remove a face I stay with 5 faces without thickness, how does the printer react to such a file? applies its minimum thickness or does not accept the file?

 

[Gattaiolato]

I put myself on some modeling test.
I made a basic model of a hypothetical house, in sketchup:biggrin:
-exported to 3ds, although the best results I got them from an obj;
-ported to meshlab, and exported to stl;
-open in minimalgics still detects some mistakes, I think 4 faces oriented badly.
At this point I hope machine software can solve the small problems of the model.
It seems to me that getting a good model for printing is a pretty demanding enterprise, compared to a rendering model.
among the modeling software which is advisable in the end to prototyping?
I heard about solidworks around here.

mechanical cads if the cavano better, are built to manage complex and articulated geometries and many have settings to choose the definition of the stl in phase of export.

 

[2¶ - progetti]

I agree...I always have big problems with the files exported by 3dstudio as well as the files exported by revit are Arabic for sw, I always have to import them to 3ds, export them tarmite a plugin bought separately, and then export them to step....
for the faces, if they are under the definition threshold, you can print the same, they turn out invisible, but it depends a lot on the geometry....the best thing is cmq verify the file inside the machine software (in my case catalyst ex) and see how it leads once simulated the printing paths. .

p.s. I didn't talk bad about google sketch up, I said that no civil engineering studio, architecture or mechanical worst, designs in this way....applying textures and managing geometries can be as expensive as the same print...for example managing a revit file and making it suitable for printing can cost 2000€. . .

...for example managing a revit file and making it suitable for printing can cost 2000€... diego

2000€: wow! a lot of hours of work I deduct it.
Sure that if these are the 3d printing costs I deduce that potential customers must have a huge interest in getting a three-dimensional model, or perhaps in this case, an industrial prototype.
diego system your site so I can browse through the works you've done. :smile:

Anyway, I did a tour of software stores... also shock a 6000€ only you sw is long. I'm thinking of taking rhinoceros in my hand, first used it in 1999 and then switching to 3dmax. Given the prices I think it's worth removing it but I'm afraid the nurbs will agree less than the poles with stl.
I unload the trial version and find out.. .
solidworks I have never seen nor used, nor I know the price. I saw a movie today that makes me say: That's cool.

hi maxopus, I saw that your studio offers, among other services of "reverse engineering". I asked for information about the base zscan but still latitano.
I was wondering what you get from the scanner? a friend of mine as a thesis took part in scanning part of the adriana villa to tivoli and, from a large 3d scanning system, they got clouds of points, which he then processed. Same thing with "object" scanners? but above all finished scanning you can go immediately in print or you have to work a lot on scanned data?

 

[2¶ - progetti]

costs? depends on the version ...standard, professional or premium...I paid the premium 12000€....but here I leave the answer to who sells by profession....and then, the nurbs of 3dstudio very frequently become "bucate" surface in stl.. at least this is my experience.. .
for the hours take into account that this phase exists only for the preparation of the models that I receive from archicad and revit (i.e. for the plastics), for the rest only a small verification in minimalgics, study the ideal orientation in the machine, some simulation and then on!! and these costs do not pour them on the customer... to the increase of experience these times fall.

hi gattaiolato, from the scanner you get a cloud of points that you can turn directly into stl.
these are always optical scanners and these have two limits:
1) do not detect hidden areas;
2) economic ones have many operating limits.

so if the model does not have hidden areas the work to do is very little (from a few minutes to an hour).

If you leave from a complex model that is not entirely detectable from the optical point of view, you may need a lot of time for your accommodation (even days).

Be careful with cheap scanners, they have many limits.
