Dr. Mike posted a blog entry in 3D Printing in MedicineHere is my video review of the Ultimaker 3 Extended for medical 3D printing. It was 4 months in the making. Medical anatomical models can be challenging to 3D print because of complex anatomy and large size. This 3D printer has a couple of features which help overcome these challenges. Ultimaker 3 Extended specfications and pricing. First, the Ultimaker 3 is a dual extrusion printer which allows for two different materials to be used during a single print. This video shows 3D printing with one water soluble material for support and another material for printing anatomical structures. I show how water soluble PVA provides support during the build and can be easily dissolved in tap water once the build is complete. Second, the Ultimaker has a large build volume compared to most 3D printers in this price range. This allows for anatomical structures to be created in one print rather than having to do several prints and putting the pieces together. While there are several good features of this 3D printer, there is still room for improvement. In this review I successfully 3D print small structures like a vertebra, but struggle with large and more complex structures like human brain and lumbar vertebrae. Watch this video review and follow along as I provide the pros and cons of medical 3D printing with the Ultimaker 3 Extended.
Ultimaker just announced the new Ultimaker 3. It looks pretty awesome. My main interest is the use of water-soluble support material, which will allow manufacture of complex anatomic structures without having to worry about support removal. For example, a skull can be printed without having to rip out the support structures inside the cranium using tweezers or pliers. I want one!
