3 Types of 3D Printing Technologies Used in Dentistry

 

Fused Deposition Modelling (FDM)

Fused Deposition Modelling (FDM) is a layer-by-layer approach where a plastic filament is heated to a semi-liquid state and then extruded to build an object. Imagine crafting a tooth using only a string of plastic! 

FDM printers are lauded for their affordability, making them an accessible innovation even for small dental clinics. They can produce durable dental models, although the detail and surface finish level might not be as refined as other technologies.

 

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) is a game-changer due to its ability to print complex geometries and interlocking parts without supporting structures! 

In the dental field, SLS technology is typically used to fabricate orthodontic models, aligners, and surgical guides, owing to its high precision and material versatility.

 

Stereolithography (SLA)

Picture a pool of liquid resin transformed into a solid object – that’s the magic of Stereolithography (SLA)! SLA uses a light source to solidify specific regions of the resin, gradually crafting an in-depth 3D object. 

SLA’s remarkable precision makes it the perfect choice for intricate dental models, molds for clear aligners, and even bite splints. Moreover, it’s renowned for providing smooth, high-resolution objects that surpass the detail level offered by FDM.
