Selective laser sintering (SLS)

additive technique

layer of powder placed on base

high power laser used to fuseselected parts of the powderthe powder bed is lowered asmall amount and a new layer of powder is spreaddoes not require any support structures3

Fused deposition modeling (FDM)

additive technique

material is laid down in layers

plastic material is melted ina nozzle that moves in XYdirectiontypically uses ABS plasticsupport material is required5stratasys

Stereolithography (SLA)

additive process

uses a vat of liquid UV-curable

resin and a UV laserexposure to the laser causesthe material to hardenafter a pattern has been traced,the platform descends and aresin filled blade recoats the toprequires support structures7

Laminated object manufacturing (LOM)

sheet is adhered to substrate

with a heated roller

laser traces out the outlineof the layernon-part areas are cross-hatched to facilitate removalof waste materialnext layer is pulled across and the process is repeated9

Slide11

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

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 technique13zcorp

Steps to Create a Part

Model part (or assembly) in SolidWorks.

Save part (or assembly) file in .

stl format.Note: To save an assembly as one single .stl file, go to Options and check the box next to ‘ Save all components of an assembly in a single file’.Run the Catalyst software. Orient the part on the build tray and send to rapid proto machine.23
