    Thorax for 3D printing

    I generated this model for cardiosurgical training simulator. I used the Obelix dataset from the Osirix dicom library. Those are the the raw 3d models of the thorax and the heart. I used those to add two mini invasive accesses to the right and a table for pig hearts in the mediastinum with the shape of the diaphragmatic of the heart. I took 2 kg. of PLA and more than 200 hours of print, sliced into 10 separate pieces and glued with cyanacrilate glue. It's quite resilient, the floating ribs are quite breakable and I don't recommend to print them. I'm adding here the raw files, because I don't know what kind of access you need on the thorax. The printed thorax can be covered with vinyl or leather for extra realism.

    Abdominal aorta aneurysm with horseshoe kidney - Postoperative

    An aneurysm of the abdominal aorta in close proximity to horseshoe kidney. Postoperative model. 
    Preoperative version. Due to the improved circulation (result of the surgery), the structures are with improved details, compared to the previous model.

    Abdominal aorta aneurysm with horseshoe kidney

    An aneurysm of the abdominal aorta in close proximity to horseshoe kidney. Presurgical model. The operation is ongoing.
    Honestly, I'm pretty happy with the result (and also the surgical team, which ordered the model). I printed it on Prusa MK3S, the kidney with the veins and the distal parts of the arteries with white Esun PLA, the aorta with red 3dJake Eco PLA, on 0,150mm layer height. The kidney is printed on 30% gyroid infill and 2 perimeters, with support on build plate only plus several support enforcers. The aorta is with 4 perimeters and 100% concentric infill, with support on build plate only and few support blockers. I glued them together with cyanacrylic glue and used a touch of red acrylic paint to make the glued parts more appealing. It took 300 grams of plastic and the printing time was 36 hours because of the kidney.

    Anatomical heart box

    This is my best selling model for 2019. Download, print, assemble, enjoy. Merry Christmas 
    Originally modded as an engagement ring box, it became really popular birthday gift for the colleague from heart-related departments. I'm selling one of those models for 35$ I'm always bringing few, when I'm going on conference. Really nice gift.
    I'm printing those with Silk PLA. The metalic colors looks fantastic. I'm using several support blockers for the atrii, because this negates the artefacts and makes the whole upper part hollow. It requires some experience...
    Slice thickness: 0,15mm
    Infill: 30% gyroid
    Circular bottom fill pattern.
    Six neodymium magnets, 8x2mm. If you use too powerful magnets, the parts are closing so strong, that they can hurt someone. N50 are fine.
    cyanacrilic glue.
    Make sure you're gluing the magnets with the right poles!

    Chimpanzee Skull - Pan Troglodytes Verus

    This model is made from 0,28mm CT scan. A female subject. An HD model for 3d printing. Source CT dataset - "Eric Delson, Kyle Viterbo, and Randall Susman provided access to these data, the collection of which was funded by Stony Brook and NYCEP. The files were downloaded from www.MorphoSource.org, Duke University. "
    I still have to revisit the nasal cavity, but the model is ready for 3d printing.

    Full head HD set - bones and soft tissues

    This is a full High definition 3D model set of a head, made from 0,7mm CT scan. Caucasian female in her 20s.
    The set doesn't include the original dataset and the metadata for ethical reasons. I can provide the dataset as a personal request.
    The set includes:
    1. Full head model of a head with the nasal cavity, paranasal sinuses, the pharynx and the superior part of the larynx.
    2. Skull model with most of the foramens. The inner ear is NOT included in the set.
    3. Mandibula model.
    4. The first 6 cervical vertebrae.
    5. The hyoid bone.
    The models are accurate, with proper geometry and measurements, in their raw format. They are also 3d printable. I can slice and dice them in whatever format you need, but I'll have to charge you additionally for that.

    Thoraco-abdominal aneurysm, preoperative model.

    This is a preoperative model of thoraco-abdominal aneurysm, Crawford typle I, with rupture above the diaphragm. The subsequent haemorrhagia in the mediastinum closed temporary the rupture, probably saving the life of the patient. This was an impossible operation, which took 7 hours and the team of the best cardio-thoracic surgeons in Bulgaria. I don't know how, but the patient is still alive and kicking. It took me 3 days to make the model and to turn it into a 3d visualization and I'll share my workflow with you. I'm printing the model right now for a cardio-thoracic surgery symposium.
    The source is Angio CT scan with 1,3 mm slide thickness.
    1. I analysed the model in Radiant Dicom viewer (you can activate trial license for unlimited amount of times, if you can't afford 100 euro for it). I selected the best series and exported them in a folder.
    2. I loaded the model in 3D Slicer. First, I run two denoising algoritms (Gradient Anisotropic Diffusion and Curvature Anisotropic Diffusion), which improved the quality of the images significantly. Then I selected a ROI, which included the whole aorta. With the Segment Editor Module I segmented the lumen of the aorta. Then, as a separate segmentation, I used the Margin operation to grow the lumen with 2 centimeters and applied a boolean operation, resulting in a hollow shell with precise lumen. I had to segment the rest of the aortic wall manually. I exported the result as STL file.
    3. In Meshmixer, I modeled the whole thing, until I was satisfied by the result.
    4. My client asked me to remove the aortic arch (it's such a pain, I love aortic arches) and to print the aneurysmal sac with the abdominal aorta and the bifurcation of the iliac arteries. Note the double renal artery. I divided the model into two parts and installed ports for two 8x2mm and two 5x2 mm neodymium magnets with tolerance of 0,250mm. The final preprint version is on picture 3.
    5. I'm printing this model with 1,5mm slide thickness, 4 perimeters, 15% gyroid infill, custom support with support enforcers, using red Natural PLA from a local manufacturer. The whole printing will take 45 hours.

    Winged Heart

    Love is in the air, so I made for you the perfect anatomically correct present for your medical professional lover. I added a set of lego wings model to  Dr. Marco Vettorello's amazing heart model.
    For best coronary artery visualization, scale to 200%. 0,15mm layer thickness(0,05mm on the upper layers for better visualization of arteria interventricularis anterior), 4 layers of raft, automatically generated support. I printed it on Prusa MK3 with generic natural PLA. If you break the wings or the holder during the removing of the support material, use cyan-acrylic glue to fix it. I added some glaze varnish "for extra kick".

    Reconstruction of facial malformation

    This is my version of the Phenix CT dataset from the Osirix Dicom Library - an infant with Treacher-Collins syndrome and aplasia of the left zygomatic bone and maxilla after a reconstruction surgery with an autograft. I wanted to preserve the small details of the maxilla and the nasal cavity, so I segmented them manually. It took me a week. The spine is not done yet - I'm redoing it and I'll reupload the whole set in the following week. The model is 3D printable, but you'll need a multi-material extruder with soluble support for this purpose - PLA/PVA will be best (PLA/PVA is much better than ABS/HIPS in my opinion). I hope you'll enjoy it
