What is a 3D Printed Anatomical Model?
A 3D printed anatomical model is a physical representation of body parts, organs or pathological conditions created using advanced 3D printing technologies. These models are based on digital data, typically from CT or MRI scans, and are transformed via technologies such as FDM, SLA and SLS into detailed copies. Where traditional models are often standardized, 3D printed anatomical models enable unique individualization for each patient. Typical examples are skeletal parts, heart, liver or models of rare diseases. If you want a more thorough introduction to the concept, you can read more at What is an anatomical model? .
Definition and basic principles
A 3D printed anatomical model differs significantly from classic plastic models. Here, the starting point is real patient data, which opens up for precise, patient-specific solutions. The most commonly used technologies are FDM (Fused Deposition Modeling), SLA (Stereolithography) and SLS (Selective Laser Sintering). FDM is suitable for coarse structures such as bones, while SLA and SLS enable very fine details, ideal for organs and complex tissues. An example could be a 3D printed anatomical model of a heart with visible vessels, or a model of a tumor for training and planning.
