Prusa 3D printing stories: University Hospital Olomouc

My name is Jaroslav Ptáček. I am in charge of Medical Physics and Radiation Protection Department in the University Hospital in Olomouc Czech Republic. We use our Original Prusa 3D printer to produce testing equipment, so-called phantoms, for machines used in nuclear medicine – this mainly concerns computer tomography devices, such as SPECT/CTs or PET/CTs. A phantom is a vessel of a specific shape with several containers of different sizes inside – these are filled with RI solution. We are using spherical containers from the original equipment manufacturer, and also 3D-printed elliptical containers – these are mainly used to compare the results with the spherical containers. It’s neccesary to use materials that have properties equivalent to human tissue – as far as gamma rays and X-rays are concerned. Materials such as ABS or PETG have density similar to water, so when the 3D-printed parts are exposed to X-rays or gamma rays, they produce results similar to human tissue. The benefits of using a 3D printer are obvious: we can design and produce custom shapes and we can have them pretty much in an instant – we don’t need to wait for someone to order a batch and have it delivered. Plus, we’re saving a considerable amount of money by 3D printing these models. We know exactly what we’re getting and that the produced objects will suit our requirements perfectly.

  1. This is so awesome! My dad actually works in this specific field of medicine imagery it nice to see how this technology seems to creep in diverse type of works

  2. I thought that it will be effective to print real vascular malformations from contrast CT 3D data and “train” doctors on specialization before min. invasive operations.
    It’s a huge job. Necessary to test different materials to present different tissues similar on CT or angio.
    But so amazing to train people for real cases with 99,(9)% safety

  3. Nice to see that someone has found a use in medical field for cheap 3d printing.
    It's always a slippery slope when hospital self manufactures devices/accessories for use with medical devices. You have to follow MDD with all kinds of standards depending on the part, and you take the full responsibility.

    I've been asked if our hospital technical department should get an 3d printer since I personally own MK3 and Elegoo Mars, and also work daily with medical device repair & maintenance.
    Sorry to say, but so far I've advised against 3d printers for now. And if we decide to get one in future, it wouldn't be Prusa nor FDM at all.
