Selective laser sintering (SLS)additive technique layer of powder placed on basehigh 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 3

Stereolithography (SLA)

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

Laminated object manufacturing (LOM)sheet is adhered to substrate

with a heated roller laser traces out the outline

of the layernon-part areas are cross-

hatched to facilitate removalof waste material

next layer is pulled across and the process is repeated

Electron beam melting (EBM)metal parts are made from a metal

powdera layer of powder is spread and the

part region is melted together by a computer controlled electron beam

3D printing (3DP)

“inkjet” type processa fine powder of plaster or corn

starch is bonded by “printing” an adhesive from the printhead

considered the fastest technique
