  • Free 3D Printed Human Anatomy Model STL Files for Medical 3D Printing

    In this week's blog entry, we'd like to share some of the best medical 3D printing models, as well as a few detailed examples that garnered the attention of embodi3D users over the past month. 3D-printable STL files like these are helping physicians and medical students to further their understanding of complex diagnoses and treatments — and your contributions are a big part of embodi3D's continued success.

     

    If you are not yet an embodi3D member, we invite you to register and take advantage of all the wonderful resources available to you. Registering is free and allows you to upload, download, and share 3D-printable medical models with our diverse community. While Gray's Atlas of Anatomy and other classic reference pieces remain beneficial, there is nothing like seeing a true-to-life, full-scale 3D model that can be held and studied. Become a registered member of embodi3D so you can access the many free resources available. 

     

    1.  Cerebrum Scan in 3D-Printable STL Format

    Dr. Mike uploaded an excellent 3D model of the cerebrum. Just look at the details of those gyri! This model was created from a high-resolution MRI scan and uploaded for use by the embodi3D community.

     

     

    2. 3D-Printable Stable Slices of a Human Heart in STL Format

    Dr. Mike has uploaded several 3D-printable stable slices of a human heart. This STL file was created using contrast-enhanced CT scans, and this upload wins our hearts for its detailed anatomy and exquisite details. 

     

     

    3. STL File of Anterior Muscles of a Human Torso

    A big "thank you" to Infinity Print for uploading this STL file featuring the sternocleidomastoid, deltoid, pectoralis major, brachioradialis, abductor longus, and other highly detailed anterior muscles of the torso.

     

     

     

    4. A 3D-Printable Model of a Dilated Biliary System

    In this upload from an MRCP image, user nevitdilmen uploaded a detailed file of a dilated biliary system (tree). This patient has a benign biliary stricture, and this 3D-printable rendering will serve as a great tool in the surgical process of correction the obstruction and fixing the hydropic gallbladder. 

     

     

    5. Scoliosis Example as a 3D-Printable STL File

    User hewtech uploaded a 3D-printable STL file to our collection of spine and pelvis stl files depicting a severe case of scoliosis, a disorder that causes an abnormal curve of the spine, or backbone. The spine has normal curves when looking from the side, but it should appear straight when looking from the front. Kyphosis is a curve in the spine seen from the side in which the spine is bent forward. There is a normal kyphosis in the middle (thoracic) spine. Lordosis is a curve seen from the side in which the spine is bent backward. There is a normal lordosis in the upper (cervical) spine and the lower (lumbar) spine. People with scoliosis develop additional curves to either side of the body, and the bones of the spine twist on each other, forming a "C" or an "S" shape in the spine.

     

    You may also want to check out the upload by user markchui, showing another highly detailed rendering of a patient with scoliosis.

     

     

    6. Full-Size, 3D-Printable Human Left Foot in STL Format

    GMorein uploaded full-size, human left foot 3D rendering to our collection of lower extremity including the foot stl files . This 3D-printable STL file was created from MRI images.

     

     

    7. 3D-Printable Mandible and Teeth Scan Featuring Deep Third Molar Inclusions

    User Nicola uploaded to our Dental, Orthodontic, and Maxillofacial STL Files Collection, this well-defined 3D rendering of a human mandible with teeth. This 3D-printable scan features deep inclusions of the third molars ("wisdom teeth"), as well as a supernumerary tooth. Great upload, Nicola! 

     

     

    8. A CT Scan Illustrating a Right Maxilla Fracture

    Dr. Raghavendra Byakodi uploaded a CT scan showing a right maxilla fracture to the Skull, Head, and Neck CTs section of the Medical CT Scan Files portion of the Downloads page.

     

     

    9. Cervical Spine 3D Model with Great Details

    This upload by FroOkk to the Spine and Pelvis section shows a 3D printable model of a cervical spine in exquisite detail.

     

     

    10. Highly Detailed 3D-Printable Human Skull 

    Last but certainly not least, James Greatrex uploaded a highly detailed human skull to the embodi3D Skull and Head category.
