Background
- Charles "Chuck" Hull (Fig.1) created the first 3D printer capable of printing an actual model and called it Stereolithography.
- 3D printing in radiology is synonymous with additive manufacturing that uses a digital model to manufacture a 3D solid object.
The process,
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 years before the term “3D printing” was used.
- “Rapid Prototyping” was the description of the process given to Hull’s unique new machine,
the “SLA-1”(Fig.2)
The same process is still used today-a 3D model is built by depositing layers on material on top of each other (Fig.3)
