14. A device that performs stereo lithography is called an SLA.
Plenary:SlA – STEREOLITHOGRAPHY
This is a common rapid prototyping technology for producing parts with high accuracy and good surface finish.
A device that performs stereo lithography is called an SLA.
Stereo lithography is an additive fabrication process utilising a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts a layer at a time.

16. Put the process in the correct order:
A wiper (arm) moves across the layer to ensure it is free from excess material and flat.
Software slices the CAD model up into thin layers.
The platform drops down into the tank a fraction of a millimeter and the laser paints the next layer.
This process repeats, layer by layer, until your model is complete.
A 3-D model of your object is created in a CAD program.
The laser "paints" one of the layers, exposing the UV plastic in the tank and hardening it.

A wiper (arm) moves across the layer to ensure it is free from excess material and flat.
The platform drops down into the tank a fraction of a millimetre and the laser paints the next layer.
This process repeats, layer by layer, until your model is complete.
It may then be cured in an oven to ensure it is fit for purpose.
