additive technique layer of powder placed on base high power laser used to fuse
selected parts of the powder the powder bed is lowered a
small amount and a new layer of powder is spread
does not require any support structures

additive processuses a vat of liquid UV-curable
resin and a UV laserexposure to the laser causes
the material to hardenafter a pattern has been traced,
the platform descends and aresin filled blade recoats the top
requires support structures7

sheet is adhered to substratewith a heated roller
laser traces out the outlineof the layer
non-part areas are cross-hatched to facilitate removalof waste material
next layer is pulled across and the process is repeated

metal parts are made from a metal powder
a layer of powder is spread and the part region is melted together by a computer controlled electron beam

“inkjet” type processa fine powder of plaster or corn
starch is bonded by “printing” an adhesive from the printhead
considered the fastest technique
