Topic: Split Larger Models

I noticed RH has an option to Cut Objects.  I tried to do this on a larger (12") stl after loading, but although it cuts it on the screen, the object still registers a collision error.  Maybe I'm missing something...

Otherwise, is there a good way to cut larger .stl files and incorporate a wave pattern or dovetail joint without specifically modeling it into the original design?  I know the Stratasys machine drivers have this function.

Re: Split Larger Models

you have to remember that both RH and slic3r are open source community projects to provide free software to run these hobby printers. its not going to provide a one stop solution for every situation. yet. go suggest the feature to the main devs, or code it up yourself and submit it to the project for inclusion in the main build!

but for now, best bet is to just plan your models for printing on your size of printer, and split accordingly. or if your working with an existing model, import the stl into blender and cut it up from there (or what ever editor you use that can work with stl format.)

God knows I do... My PPG model is 12 pieces because I have an SD2 so a 6 inch cube is limiting... HOWEVER it's wholly do-able and most of the pieces are halves so that you can join it and so it looks pretty and takes a lot less time to repair.

Re: Split Larger Models

Here is the method I have been using in Solidworks...still would like to have an RH function to do this, but I am not a programmer!

Re: Split Larger Models

this might be  useful:

Thingiverse script for splitting models in a puzzle cut (great for good surface area for the bond)

There are probably several scripts like this.

Re: Split Larger Models

Tomek,

Nice!  But I get short-circuited by lines of coding...need to directly manipulate visually...just a crotchety old man perspective :-)

Why not use NetFabb to cut the STL?  It works extremely well.

A lot of models are made up of different parts, and even thought the STL appears as a single entity, NetFabb has the capability of separating the parts and saving them individually. Kinda like disassembling a model kit.

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

...and too much time on my hands.

Re: Split Larger Models

Apparently Netfabb's free-cut feature (ironically named) is only available in the pro version...

I guess I'll stick with my method for awhile...

Re: Split Larger Models

I do this sort of thing in Blender with a boolean modifier. Slicing models apart with cubes. It's messy, but works rather well.

Re: Split Larger Models

Meshmixer is good at splitting models, and also free.

Re: Split Larger Models

You can split your model in Blender. This explains how to do it as well as how to make it a separate part:
