3. Selective laser sintering (SLS)
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

5. Fused deposition modeling (FDM)
additive technique
material is laid down in layers
plastic material is melted in a nozzle that moves in XY direction
typically uses ABS plastic
support material is required
stratasys

7. Stereolithography (SLA)
additive process
uses a vat of liquid UV-curable resin and a UV laser
exposure to the laser causes the material to harden
after a pattern has been traced, the platform descends and a resin filled blade recoats the top
requires support structures

9. Laminated object manufacturing (LOM)
sheet is adhered to substrate with a heated roller
laser traces out the outline of the layer
non-part areas are cross- hatched to facilitate removal of waste material
next layer is pulled across and the process is repeated

11. Electron beam melting (EBM)
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

13. 3D printing (3DP) “inkjet” type process
a fine powder of plaster or corn starch is bonded by “printing” an adhesive from the printhead
considered the fastest technique
