Fused filament fabrication (FFF) also known under the trademarked
term fused deposition modeling (FDM), sometimes also called
filament freeform fabrication, is a 3D printing process that
uses a continuous filament of a thermoplastic material. ...
The print head is moved under computer control to define the
printed shape.
Stereolithography (SLA) is the oldest form of 3D printing.
It works by exposing a layer of photosensitive liquid resin to a UV-laser beam;
the resin then hardens in the desired pattern, and the object is built layer by layer
until it is complete.
This allows you to print a model with extremely fine detail.
