Medical 3D Printing ZTips/Tricks

Hello everyone,

I was posting this in hopes to maybe find out some particular settings and tips/tricks people use when printing out anatomical models (skulls,brain etc) as I have been offered an opportunity to print models from CT Scans supplied by some local surgeons wanting models of their patients fractures and what not. I have already printed 3 frontal orbits from scans using the stock profile from Cura (Fine 0.15mm) with supports everywhere as the prints can be very intricate but I had a slight mishap with the very previous print. It seemed that some of the supports had actually fused into some parts of the nasal cavity and this loses the accuracy of the file. My supports seem to be very tough to actually pull from the print so I have been resorting to soaking it in warmish water which seems to be helping a small amount.

I'm using my Mk3S. 0.4mm Nozzle, PrusamentPLA, Standard Fine 0.15mm Cura Profile, Supports Everywhere

If anyone maybe has some profile settings they would/do use for this line of work it would be greatly appreciated! 🙂

Hi there,

apologies to reply with a question rather any help to your problem (although I will watch closely for answers as this is something that happens to my prints as well).

My question is how do you get your .stl files from the scans? Is there any specific software involved or are you just using the 3D-recons provided by the CT scanner? Would be interesting to get some potentially printable things out of a standard DICOM file without having to suck up to our radiographers 😉

Cheers

Hello, 

So I use either InVesalius or 3D Slicer when importing DICOM files from the cd provided from surgeons/ medical imaging folk! I personally find 3D Slicer to work better for me as it's a bit more user friendly while also having a very wide variety of different options/settings/plugins. Seems to be heaps of plugins made by professionals which is also great sifting through them as well. You can also use the website Embodi3d to render NRRD files you can create from the DICOM files and it will use it's algorithms to pull out whatever option you choose. Hope that helps :).

 

Kind regards,
Zach
