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 techniquematerial is laid down in layersplastic material is melted in

a nozzle that moves in XYdirection

typically uses ABS plasticsupport material is required

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
