  12. Version 1.0.0

    This model is the right knee bone rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. The knee is composed of 3 separate joints: two hinge joints (medial and lateral femorotibial joints), and one sellar, or gliding, joint (the patellofemoral joint). These also compose the three compartments of the knee: medial, lateral, and patellofemoral. Although the knee is thought of as a hinge joint, it has 6 degrees of motion: extension/flexion, internal/external rotation, varus/valgus, anterior/posterior translation, medial/lateral translation, and compression/distraction. To provide stability to the joint, static and dynamic stabilizers surround the knee, including muscles and ligaments. The major ligaments that provide stability to the knee include the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral (or fibular) collateral ligament (LCL), and medial collateral ligament (MCL). The ACL prevents anterior translation of the knee and the PCL prevents posterior translation of the knee. The LCL prevents varus stresses and the MCL prevents valgus stresses on the knee. Furthermore, the medial meniscus is a secondary stabilizer to anterior translation and is therefore commonly injured during an ACL tear or after an untreated ACL tear. This model was created from the file STS_022.

    This is a case of 56-year old female patient with right thigh swelling, histo-pathology revealed it to be solitary fibrous tumor of the right thigh with intermediate grade of malignancy. MRI and PET scan were done for this patient after the initial diagnosis by 3 and 36 days respectively. Her treatment plan included radiotherapy and surgical resection of the tumor combined. upon 637 days of follow up , the patient showed no evidence of disease (NED). This STL file had been created from a CT scan DICOM dataset and is availabe for medical 3D printing .

  18. Cutting down costs for 3D prints is the number one concern for many Doctors and Patients. In order to achieve this, we need to understand how costs for 3D prints are calculated. Probably the most important variable is the amount of material that is needed for printing your medical object. So all we need to do is to make sure to use as little material as possible. Here are our some top tips for more successful 3D printing. They're short and to the point, and if you follow them, you'll find your models will stand straight and look beautiful. Create a hollow 3D model & 3D print with Escape Holes if needed. A hollow model means that the interior of your object will not be solid. Solid designs are not necessarily a problem – they will be stronger and harder to break (depending on the material), but they will also be more expensive as more 3D printing material will be used.With a hollow model the interior of your print will be empty (in theory). However, since our printers print layer by layer, 3D printing material can get trapped in the interior of your model. If you would like to avoid this, you can add ‘escape holes’ to your design. Material that is not used for building your 3D print can then be removed. However, creating a 3D model with an empty interior can be a bit tricky, you need to know how to hollow your model in the 3D modeling software you’re using, you need to define a wall thickness that is strong enough for your model not to break, and it probably makes sense to add so-called ‘escape holes’ to your model Why do I need escape holes? As already pointed out, our 3D prints are created layer by layer. With a hollow interior, this means that 3D printing materials can get trapped inside the object. A hollow model full of trapped powder is in danger of deforming. Escape holes are recommended for getting ‘trapped’ 3D printing material out of your 3D print. We typically use pressurized air for cleaning the excess powder off. How do I design escape holes? Again, the exact procedure depends on your software but the idea is often the same: create a cylinder at the bottom of your model and extrude or subtract from its wall Use supports If you plan on printing out a figure as one solid piece, you'll want to consider placing supports at overhang areas. Some slicing/preference software will do this automatically. The Infill for FDM 3D Printing The Slicing softwares lets you adjust the infill percentage and infill type to print your model in FDM. Choosing the correct percentage and type of infill depending on how strong you want your model to be can reduce the volume of your model making it cheaper. Know your materials Learn the tolerances of the various materials used. It's better to err on the larger side, because you can always sand or trim down the piece afterwards. Happy 3D Printing!!

  24. Occasionally files uploaded to the democratiz3D service for conversion to STL will not process correctly. What should you do if this happens? Usually these failure are due to one of two items: 1) There is some problem with the uploaded file, or 2) The uploaded file is simply massive (i.e. head to toe thin cut CT). If you encounter a problem with processing of your file, the first thing to do it check the quality of your input file. See my earlier tutorial, Choosing the Best Medical Imaging Scan to Create a 3D Printed Medical Model, if you want more details. 1) Check the modality. Did you upload an MRI when the operation calls for a CT? 2) Check for artifacts. This will often cause the model to have obvious deformities. The most common is beam hardening from dental fillings, as shown below. Normal teeth without fillings are on the left, and teeth with metal dental fillings are shown on the right. Unfortunately, you can't make an STL file from data that isn't there. If you scan has lots of artifact, you can either choose another scan or go through the laborious process of fixing the artifacts manually after the model is created. 3) Reconstruction kernel. This refers to the edge enhancement or sharpening algorithm that was applied to the scan images after they were acquired on the scanner. These are often done on dedicated bone or lung CT scans to enhance the contrast as make it easier for the radiologist to see subtle findings, like hairline fractures. Which the edge enhancement algorithm (or sharp kernel) as shown on the left below makes the edges easier to see, it also results in a speckled or noisy appearance of the tissue. This can confuse the algorithm because some very high intensity spots may look like bone. If your file is failing and you are using a sharp kernel series from you scan, consider using a different series that has a smooth kernel, such as shown on the right below. If you must stick with the sharp kernel, increase the threshold level to reduce the amount of "sand" in your output file and increase the changes of a successful processing job. Hope this helps, Dr. Mike
