Full Version: STL save as assembly

Show messages:  1-3  4-23  24-28

I'm exporting parts from MOI as .stl files and 3D printing them without a problem.
Just select the part, then use export.

"""""""Just select the part, then use export."""""""""""""""

What he's saying though, is if he has 100 parts and does the export, the "stl" is one solid stl file with no individual parts selectable...........

Hi Grendel, I think it should be possible to cook up a script that would export a separate STL file for every object, I'll see what I can do.

There isn't really any proper way to store multiple parts within one single STL file itself, the STL format was mainly intended to store just one solid in the file, it just has a big heap of separate triangles in it with no connection information. If parts don't touch it might be possible for a receiving application to sort things out but if they touch it's pretty difficult to figure out which triangles were supposed to go with which particular part.

Hi Grendel, I've attached a plug-in which I think may help you.

To install it, copy the attached file SaveMultiSTL.js into the \commands sub-folder. That will a make a new command named SaveMultiSTL available, set up a shortcut key with SaveMultiSTL for the command name and then when you trigger it, it will prompt you for a filename and then output each object in your model out to a separate STL file with a number incremented on it.

So for example if you have 3 objects and you give it a filename of c:\files\file.stl it will generate 3 files in that folder named file1.stl, file2.stl and file3.stl

The only downside is that I thought you probably did not want the mesh options dialog to pop up for every separate object that is being saved, so it suppresses that and instead uses a hard coded setting of Angle = 5. You can edit that at the top of the file to change it to something else if you want.

I hope this will help out.

BurrMan - You are correct that is exactly the case regarding the multiple stl requirement

Mike - As BurrMan points out I need the multiple stl files as my printer prints in multiple materials at once and when I import a single stl assembly there is some overlap where shells touch from the components that share a boundary with another shell. Objet studio just lumps everything together and cannot separate the shells internal to the program

Michael - That is exactly what I needed, thank you for your help. I will try this out when I get to the shop this morning and confirm it works. I will also post the result of the print as well.

Hi Grendel,

I'm just curious about you 3d printing an assembly, are you printing the object as an assembly or are you laying out separate pieces of the assembly on the printing plate?

I am printing an assembly as a unit on the plate, here is the progress from plate, to support removal to final clean up

way to push the print.... Nice piece Grendel. Wow!

---

Hi Grendel, wow that's some pretty sophisticated printing with multiple materials and components all produced at once, cool!

I'll post more detailed ones later. The script worked perfectly, thank you Michael. I output a 507 piece model using it and it just chewed through it no problem and imported perfectly with all the mesh separation.

Hi Grendel,
I used to work with American Marine Services who sent off a couple newt deepworkers and pilots to the gulf area. Maybe they are installing some of your devices!

Anyway..........

All my subsea equipment gets deployed between 500-12,000ft so we use unmanned ROV's for physical interaction if the primary control system has a problem. When I was in the Navy I worked at the Deep Submergence Unit and we had a couple Newt suits, Avalon, Mystic, Sea Cliff, Turtle and unmanned ROV's.

Intense stuff.... :o

Take care.

OK, here is a telescopic riser joint I am using as a classroom aid for my training program..

An actual TJ in service onboard an offshore rig. It is 65 feet long and 75,000lbs.

Me likey!!!

Is that render still Carrara?

---

Yes it is....old habits die hard

---

I would have to say I don't think I've seen anybody render with Carrara as well as you..... I wish I was a fly on the wall in your work area for a bit....

Thanks for sharing.

---

LOL....You would hear a lot of cursing and screaming that DAZ has let the product languish technically since they purchased it to emphasize their....."content" delivery

---

It would just be ambient noise while I focus on what your doing.

Ray Dream was my first 3d modeler.

A quick print out of the CreatureBox JellyBean character, I used to paint warhammer figures years ago so I will break out my paints and get him colored up. The figure is about 4"" tall, I had to change the diameters on the arms cylinders and fingers to get them to be rigid enough to clean up...still has the same feel though
