  1. EML 2023 Rapid Prototyping

  2. Technologies

  3. Selective laser sintering (SLS) • additive technique • layer of powder placed on base • high power laser used to fuseselected parts of the powder • the powder bed is lowered asmall amount and a new layer of powder is spread • does not require any support structures

  4. Technologies

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

  6. Technologies

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

  8. Technologies

  9. Laminated object manufacturing (LOM) • 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

  10. Technologies

  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

  12. Technologies

  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 zcorp

  14. Technologies

  15. UF machines - FDM • Dimension Uprint (Soluble Support Technology) Building MAE-B

  16. UF Rapid Prototyping Machines sodium hydroxide & water tank 101012” build volume 868” build volume
