Technologies Prototyping Technologies Base Materials Selective laser sintering (SLS) Thermoplastics, metal powders Fused deposition modeling (FDM) Thermoplastics, eutectic metals Stereolithography (SLA) Photopolymer Laminated object manufacturing (LOM) Paper Electron beam melting (EBM) Titanium alloys 3 D printing (3 DP) Various Materials EML 2023 Department of Mechanical and Aerospace Engineering 2
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 EML 2023 Department of Mechanical and Aerospace Engineering 3

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 EML 2023 Department of Mechanical and Aerospace Engineering 5

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 EML 2023 Department of Mechanical and Aerospace Engineering 7

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 crosshatched to facilitate removal of waste material • next layer is pulled across and the process is repeated EML 2023 Department of Mechanical and Aerospace Engineering 9

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 EML 2023 Department of Mechanical and Aerospace Engineering 11

3 D printing (3 DP) • “inkjet” type process • a fine powder of plaster or corn starch is bonded by “printing” an adhesive from the printhead • considered the fastest technique EML 2023 Department of Mechanical and Aerospace Engineering zcorp 13

Steps to Create a Part 1. Model part (or assembly) in Solid. Works. 2. 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’. 3. Run the Catalyst software. Orient the part on the build tray and send to rapid proto machine. EML 2023 Department of Mechanical and Aerospace Engineering 23
