Internal latticing a requirement for 3D printing?

[BioGuy]

Hello all,

 

I have initially uploaded a few very high quality models that I had produced from a small collection of high resolution CT scans I have. They are all in manifold STL format.

Here are some screenshots of a full spine model, high resolution ear, pelvis, and full heart lumen model which I have attempted to convert into an assembly/display model with a base:

 

 

My personal usage for these models has been for computer simulations, so I'm not too familiar with the requirements for a good 3D printable model.

 

- Is it typically a requirement to have latticed internal volumes to reduce material costs?

- What about dowels/pins so that the model can be assembled? Do people usually want this?

- Are there any other considerations that would make these models more valuable to the community - I potentially have a few more anatomies that could be of value.

 

Many thanks.

Thanks for sharing these high-detail anatomical models! Many students visit Embodi3D and this type of models is very useful to them. About your questions, maybe Prof. @valchanov and @Dr. Mike could help you.

In my experience, the model have to be solid and without internal meshes. The material cost can be controlled with the percentage and the type of the infill.

- What about dowels/pins so that the model can be assembled? Do people usually want this?
If you're printing a bone model in two parts, its better to glue them together after the print. If you're printing a model with a important cavity (skull or aorta), pins or sockets for neodymium magnets are a choice, which guarantees good alignment for the parts of the model and increases usability. The magnets are better, unless your client specifically prefer pins.

- Are there any other considerations that would make these models more valuable to the community - I potentially have a few more anatomies that could be of value. Make them shinier, more stable and design a stand for the model.
