3D Printing is a manufacturing process that creates a physical object from a digital design.
Technically nearly every manufacturing process in the the world utilizes this technology in some way or the other.
It is now becoming an important method for Radiologists to communicate pertinent findings to medical care teams especially in surgical branches.
We are presenting the concept,
process and applications of 3D printing in Medical Imaging.
Charles "Chuck" Hull (Fig.1) created the first 3D printer capable of printing an actualmodel and called it Stereolithography.
3D printing in radiology is synonymous with additive manufacturing that uses a digital model to manufacture a 3D solid object.
also known as rapid prototyping,
expanded widely in the 1990s in architecture and manufacturing.
The terms additive manufacturing and rapid prototyping are,
for the purpose of this review,
synonymous with 3D printing.
Charles Hull’s first 3D printer proved successful on March 9 1983-over 30 yearsbefore...

DIFFERENT TYPES OF 3D MODELLING:
7 Main types-all use different technologies (Fig.4)1
Material Extrusion (the type our printer does)
Powder Bed Fusion
Direct Energy Deposition
3D printers do not accept DICOM images.
A standard file format to define3D modelsis Standard Tessellation Language (STL).
The STL format defines surfaces as a collection of triangles (called facets) that fit together like a jigsaw puzzle.
A newer format called Additive Manufacturing File Format (AMF),
was approved by ASTM International...
3D printing is one of the emerging and most promising new paradigms in Medicine spearheaded by Medical Imaging.
Radiology needs to takecharge of 3D printing.
Integrate it with our 2D reports as a 3Dmodel to enhance the value of our "products".
Rapid expansion in the use and application of 3D models as described.
Endless applications and opportunities to collaborate.
