  1. EML 2023 – Rapid Prototyping Lecture 1 – Additive 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 1200es SST (Soluble Support Technology) Building MAE-B Room 313

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

  17. former UF machine - FDM

  18. Existing Equipment • 2 Dimension sst 1200es Rapid Proto Machines • ABS plastic • 101012” build volume • .010” z-axis, .005” xy-axis resolution • Roland MDX-540 Subtractive R.P. machine • plastic, wood, aluminum • 4 axis ; 4 tool magazine • 4412” build volume • .0008” repeat accuracy

  19. Existing Equipment • Next Engine 3D Scanner • 54” macro field of view • 13.510” wide field of view • .005” accuracy

  20. Equipment to be delivered • Fortus 360mc Rapid Proto Machine • ABS plastic, Nylon, polycarbonate • 161416” build volume • .005” accuracy • 1.5 speed compared to existing machines

  21. MAE-B 313 Lab Renovation Plan

  22. 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.
