1, obtain the human organ digital model: through medical imaging technology (such as CT, MRI) to obtain the digital three-dimensional model of the human organ, and related trimming processing, so that it is suitable for 3D printing.2. Select 3D printing equipment: according to the size of the desired organ, complexity, material and other factors, select the appropriate 3D printing equipment, such as FDM, SLA, SLS and other technologies.3. Preparation of 3D printing materials: Select materials suitable for the chosen 3D printing device, and carry out the necessary pre-processing, such as cutting, slicing, model support and so on.
3D printing (3DP) that is, one of the rapid prototyping technology, it is a digital model file as the basis, the use of powdered metal or plastic and other bondable materials, through the layer-by-layer printing to construct the object of the technology. 3D printing is usually used digital technology material printer to achieve. Often used in mold making, industrial design and other fields to manufacture models, and then gradually used in the direct manufacture of some products, there have been parts printed using this technology. The technology is used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields.
