  • Rapid  prototyping     for  jewelry                  JD171  OL1  :  Materials  &  Proper=es                   Spring  2012                                                Professor  Steven  Parker                            By  Cho=ma  Vachiravu=chai  
  • Rapid  prototyping  •  is  a  machine  that  used  to  create  a  model  that   designed  by  using  3D  computer  aided  design   (CAD)  data.    •  The  first  machine  of  rapid  prototyping  hit  the   markets  in  the  late  1980s.  •  in  its  earlier  days  was  applied  to  produc=on  of   models  and  prototype  parts.  But  nowadays   with  the  advancement  in  technology,  rapid   prototyping  is  used  widely  for  many   applica=ons.        
  • Rapid  Prototyping  machine     used  in  Jewelry              There  are  many  companies  out  there  that  developed  Rp   machine  for  jewelry  fabrica=on.  However,  I  will  specifically   talk  about  two  most  common  brands  and  types  that    use  in   the  jewelry  field  these  days.  I’m  not  including  the  CNC   machine    here  because  in  my  opinion  the  machine  does  not   work  fast  enough  to  use  the  word  ‘rapid’!                                    2  types  of  the  RP  machine  in  focus…    •3D  prin=ng  from  solid  scape;  an  inkjet  printer  that  using  hot  wax  instead  of   using  ink  building  a  model  in  3D.    •Stereolithography  from  envision;                Uses  a  light-­‐sensi=ve  liquid  polymer.        
  • “  Model  making  process     from  solidscape  ”   •  Transfer  the  finished  design   in  STL  file  that  created  from   CAD  to  the  machine   •  Set  up  the  file  in  a  sodware   called  Modelworks  that   come  with  the  machine     •  the  machine  will  apply  the   wax  layer  by  layer  to  create   3D  models  by  prin=ng  the   suppor=ng  surface  in  the   pink  wax  and  the  real  model   in  the  blue  wax.      
  • •  Take  the  plate  with   the  completed   models  to  the  hot   plate  so  you  can   remove  the  model   out.  •  Then  place  the   pieces  into  a   cleaning  solu=on   to  clean  off  pink   base  wax  and  dry   the  pieces  to  get   ready  to  be  cast  or   making  a  mold  out   of  it.    
  • “  Model  making  process   from  Envision  ”    •  This  machine  builds  the   model  up-­‐side-­‐down  by   laser  one  layer  at  the   =me  crea=ng  interior   and  exterior  feature   including  support  and   sprue.    •  Clean  the  finished   pieces  in  a  cleaning   solu=on  and  the  piece   will  ready  to  be  direct   cast  or  make  a  mold    
  • Machines  overall  •  These  machines  make  the  jewelers’  lives  easier.  We  can  see   the  3D  model  from  the  CAD  program  and  then  transfer  the  file   to  the  RP  machine,  here  the  process  called  WYSIWYG  (What   You  See  Is  What  You  Get)  takes  place  wherein  the  final   product  is  same  as  the  image  created.  •  The  materials  in  use  are  non-­‐toxic  thermoplas=c  for  the   solidscape  and  photopolymer  for  envisiontec  which  is   featuring  lost  wax  cas=ng:  fast  melt  out,  no  ash  or  residue  ;   this  make  the  process  free  from  porosity  and  no  thremal   expansion.  •  Such  a  machine  makes  no  more  =me  consuming  for  carving   wax  
  • Machines  overall  •  To  decrease  the  waste  of  wax  or  metal  and  also   decrease  the  development  =me  by  allowing   correc=ons  to  a  product  to  be  made  early  in  the   process  when  the  model  s=ll  be  a  STL  file.  •  Increasing  product  complexity;  designers  can  be   more  crea=ve  as  the  computer  program  lead   them.  Unlike  CNC  machine  that  have  a  tool   limita=on  that  can  not  carve  a  hallow  form  and   too  complex  shape.  •  To  Provide  clean  smooth  surface  of  the  prototype   and  also  precise  with  out  lower  the  speed.      
  • Machines  overall  •  Decreasing  delivery  =me;  3D  prin=ng  machine   and  stereolithography  (digital  wax)  works  a  lot   faster  and  making  more  pieces  in  the  same   period  of  =me  compare  to  CNC  machine.  
  • Sustainability  and  environment  impact  •  Non-­‐toxic  thermoplas=c  composites  will  not   harm  the  environment  where  they  are  placed.   Unlike  other  materials  that  release  chemicals   over  =me  •  Thermoplas=c  is  a  polymer  that  can  remelted  and   remolded  many  =mes.    •  Liquid-­‐Photopolymer  releases  26%  CFC-­‐11   equivalents  (  ozone  deple=on  factor)  •  Liquid-­‐Photopolymeris  a  water-­‐base  so  no   chemical  that  harm  the  environment.    
  • The  use  of  RP  machine  in  general  
  • The  use  of  other  types  of  rapid  prototyping  in   many  applica=ons  
  • Future  predic=on  for  the  machine  in  Jewelry   fabrica=on  •  Be  more  faster  and  more  precise  •  Bigger  in  size  that  could  make  the  bigger  piece   and  more  pieces  at  the  same  =me      •  Become  a  main  tool  for  the  jewelry  produc=on  •  No  Need  to  store  too  many  metal  models
