  1. Hello!, maybe this model printed by @valchanov could help you, regards
  2. Hello you can try with https://www.radiantviewer.com/
  3. Hola a todos!, gracias por sumarse a esta comunidad. Estoy convencido que podremos construir un lugar donde realmente podamos incrementar y evolucionar el conocimiento alrededor de Embodi3d y de la impresión 3d para fines médicos. La idea es que dentro de este apartado se vayan presentando. Un abrazo y nos estamos leyendo Angel Sosa.
  4. It's an innovative solution that can be put into practice during this crisis, as it can be considered when there is a shortage of FFR. The CDC puts it as an option (although it needs more research) when there is a crisis, some studies guarantee that the quality of the material may or may not be affected depending on the dose and the model of facial mask used. Nebraska Medicine has implemented a protocol for UV irradiation of N95 respirators in the context of the COVID-19 pandemic based on the dose generally needed to inactivate other single-stranded RNA viruses on surfaces: Lowe JJ, Paladino KD, Farke JD, et al.

  8. In recent weeks we have seen that the spread of the Coronavirus has increased. However, on the good note, we have also seen an increasing number of people willing to help. Thousands of people from around the world who have 3d printers have share their contact information, creating a large database, offering their knowledge in 3d technology (mostly non-profit) to help in this fight against coronavirus. In Spain, for example, thanks to the biomedical3d company, some hospitals such as the University Hospital of Virgen del Rocio and Hospital Puerta del Mar, have been testing the 3D printed hands-free door openers that help in preventing the transmission of the covid19 as the staff don’t need to touch the doors to open them. Other organizations such as Ayudame3D, have printed face shields. Currently, each Ayudame3D volunteer has the ability to create one every 3/4 hours. They are part of a group called "Coronavirus makers", a group of people from different fields (medicine, biotechnology, 3D printing, industrial design, among others) that decided to share their knowledge and experience in a Telegram group and at their website to co-create artificial respirators and other solutions by using 3D technology. Since the onset of the COVID19 crisis, Coronavirus Makers volunteers have delivered more than 350,000 face shields using more than 9 tons of material. Isn't that amazing? Another Spanish company that is joining these initiatives is Leitat Technological Center. They have used 3D printing to make an emergency ventilator, costing less than EUR 500. It's in testing now. Their goal is to share the files for free, so the 3D printing community around the world can contribute to saving lives. There is now a large network of 3D printing against coronavirus in Spain, which currently has more than 1,000 printers and more than 300 professionals, and they are still looking for more volunteers to join the initiative. Those with a 3D printer and interested in join this team can register at 3dcovid19.tech. Files availables Take a look at some of the files that are available now and that can help protect you from COVID-19. Respirator Adapter for Decathlon Mask – These files allow you to convert a recreational mask into a respirator. Hands-Free Door Openers – These can go a long way in reducing the spread of infection in businesses and offices that must remain open. They can fit on a variety of doors and allow users to open doors with their forearm rather than their hand. Bonus: Leave them on after the crisis and people can open doors while carrying coffee and documents. ‘Savegrabber’ Door Opener – While the previous door opener mounts to the door handle, this one is portable and can be used on most lever door handles. Reusable Filter Mask – This simple mask allows users to change the filter material out regularly and it works with HEPA filters, coffee filters, and paper towels. Face Shield – This was designed by Canadian ER worker Dr. Tarek Loubani. All that’s needed is some elastic strap and Mylar sheet. Those with more complex materials and equipment available can take a look at the most complex files designed by the Isinnova team: The Venturi valve – The original that started it all. Protective face shields by prusa3d in Czech republic. There are more organizations that have recruited volunteers to join forces and fight COVID-19. Fathom is working to design printable nasopharyngeal swabs for COVID-19 test kits as well as ventilators. You can also be part of the CoVent-19 Challenge. It was founded by residents at Massachusetts General Hospital as “An Open Innovation Effort to Design a Rapidly Deployable Mechanical Ventilator” using additive manufacturing. Participants will be allowed to submit multiple designs during Round 1, and participants may choose to submit full system designs and/or modules/parts for other teams to integrate into their design. Do you know any other initiative? leave us your comments!
  9. LIVERPOOL, N.Y. - A couple of entrepreneurs Isaac Budmen and Stephanie Keefe are making 300 face shields to help help workers at a coronavirus testing site in Syracuse County. They make and sell 3D printers in their house by the name of Budmen Industries. Last Saturday they produced 50 shields using seven 3D printers, they are now using 16 printers to produce 250 before the end of this week. "It just sort of felt right to us to do what we could to help the situation," Budmen said. They started their business in 2017, they spent most of Sunday trying to translate their idea that the protective shields were easy and comfortable to use. Since then they have not stopped producing the shields requested by the county. This is an example of solidarity in these times of crisis due to the pandemic. The couple has not set a price for the prints and they have focused on producing them to help their community. This is how Budmen put it "I just said we'll get it done," “We're really not looking to make money off the county in this crisis. Onondaga County Executive Ryan McMahon gave the couple a big shout-out during his daily update on the coronavirus pandemic on Tuesday. Budmen said he and Keefe got to work designing the shields as soon as soon as they heard the county was planning to open a site in the city where people could go to be tested for the coronavirus. They figured the county would need face shields for the safety for workers performing the tests, he said. However, the county has agreed to pay for the shields for what is estimated to be an approximate price of $ 8 for the expenses for the materials used. This is another story worth sharing with you.

  11. In Italy, young entrepreneurs used their engineering skills with high precision combined with their passion for 3D printing to create 3D printed valves that can be connected to machines to help coronavirus (COVID-19) infected patients breathe. Chiari Hospital General Manager Mauro Borelli on the phone confirms that not only are the 3D-printed "life-saving" valves working properly, even a second improved model from the first version has been developed, "which generates less friction." This is a beautiful story during the coronavirus season that fills us with hope. The idea arose due to the need for valves to connect the breathing helmets to the oxygen cylinders, not available in the market because the manufacturing company was saturated by the number of orders. How to do it "Why not try recreating them with a 3D printer?" It was intuition. In a round of calls, the SOS del Mellini di Chiari recovers in the editorial office, at the hours when the solidarity of AiutiAMObrescia runs fast, to reach Massimo Temporelli, a physicist, entrepreneur and scientific disseminator, who among the fablabs finds the immediate availability of Cristian Fracassi and Alessandro Ramaioli, young engineers from Brescia who get to work. In a few hours they print 3D prototypes. Then Mellini is presented with the first fifty valves ("It's actually a Venturi tube, a hydraulic invention that dates back to the 18th century," says Borelli, an engineer himself). Ready it is, everything works. A small miracle in which Brescia's technology, heart, competence and determination made the difference. For many as for Antonio, 60 yo, he admitted Mellini by covid-19, among the first to benefit from the "valve that saves lives." Without which he would now struggle to breathe. Instead, his course is progressing well. For the two young engineers, hours of unremitting work to produce a hundred of these valves, but the smile behind the masks also outweighs signs of fatigue on the face. And their commitment is reflected in the immediate availability gathered by many other companies in the medical and 3D printing sectors, such as Invatec-Medtronic, Only 3D, Fabula 3D. Digit of the generosity of Brescia. REFERENCES 1.

  15. This has been an amazing year for us at Embodi3d and we'd like to share with you the best 3d medical printing models of 2019 1. A great brain 3d model, the first place! uploaded by Osamanyuad. This example shows the cortex which is a thin layer of the brain that covers the outer portion (1.5mm to 5mm) of the cerebrum. 2. A heart 3D printed model uploaded by Tropmal. It shows the coronary arteries that supply oxygenated blood to the heart muscle, excellent for educational purposes. 3. Portal vessels anatomy uploaded by Platypus1221. The portal vein or hepatic portal vein is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. 4. A Dental Cone-beam Computed Tomography in an adult orthodontic patient uploaded by R Thomas. The cbct is an advanced imaging modality that has high clinical applications in the field of dentistry. 5. A kidney 3D .STL file uploaded by Shahriar The kidneys are a pair of organs found along the posterior muscular wall of the abdominal cavity. The left kidney is located slightly more superior than the right kidney due to the larger size of the liver on the right side of the body. This is an excellent example in .stl format. 6. 3D Printable Human Heart Model with stackable slices, short axis view uploaded by Dr. Mike. This 3D printable model of a normal human heart was generated from an ECG-gated contrast enhanced coronary CT scan. The slices are cut to illustrate the echocardiographic short-axis view. If you are interested in a 3D printable heart that shows slices in the anatomical transverse plane, 7. A bony hand in a .STL file processed uploaded by MABC The wrist has eight small bones called the carpal bones, or the carpus. These join the hand to the two long bones in the forearm (radius and ulna). The carpal bones are small square, oval, and triangular bones. The cluster of carpal bones in the wrist make it both strong and flexible. This incredible 3D medical printing model shows all the bones and joints for learning purposes! 8. 3D Prenatal Ultrasound uploaded by kevinvandeusen The 3D ultrasound images provide greater detail for prenatal diagnosis than the older 2D ultrasound technology. 9. A bony knee in a .STL file processed uploaded by Yousef97 In this example we can evaluate the knee joint in three parts: The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint. 10. A lower extremity CT scan of a femoral fracture uploaded by Yondonjunai The femur is the largest bone in the body, and consequently it is often thought that high energy mechanisms are required to produce a femur fracture. You can see an example here: 11. An skull fracture example uploaded by Raspirate This example shows a fracture skull. The skull is a bony structure that supports the face and forms a protective cavity for the brain. 12. A CT chest scan with contrast upload by Nikluz This example shows the vascular structures and thorax muscles. 13. 3D-Print a Left Knee Joint Model with this Excellent STL Upload (Converted from CT Scan) by Niels96 A 3D model of left knee, we can see that is formed by three bones: the femur, the tibia and the patella. the knee joint is the largest synovial joint and provides the flexion and extension movements of the leg as well as relative medial and lateral rotations while in relative flexion. 14. A Huge thoraco-abdominal aneurysm (preoperative model) by Valchanov This is a difusse dilatation of aorta with a high risk for rupture. Most of the patients are asymptomatics and accidentally discovered on routine chest radiography. 15. A stl file showing the elbow´s bones by Pekka The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. The ends of the bones are covered with cartilage. 16. A CT scan of Left Knee Joint Model by Niels96 Computed tomography scan (CT or CAT scan) is a non-invasive diagnostic imaging procedure that uses a combination of special X-ray equipment and sophisticated computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. In this example we can evaluate the knee with detail. 17. A 3d model of a polytrauma pelvis in a .STL file by Narkos. This patient suffer a polytrauma right hemipelvis with fracture S1-S2 and fracture of the ischiopubial branch. 18. A full body CT scan by davidmorris80@oulook.com A whole body scanner images without injection with window function that allows the study of the soft tissues, including lymph node structures, mediastinum and abdomen. 19. A .STL file of a left temporal bone ready for 3d printing by Nicola Di Giuseppe. This shows the mastoid, malleus, incus, the bony canal of the facial nerve and the stylomastoid foramen excellent for learning purposes. 20. An Anatomical heart box 3d model by valchanov This was valchanov´s best selling model for 2019!
  16. Great work! valchanov
