3 D Printing part finishing We have two 3D printing systems that we produce metal and plastic parts. We are finding the surfaces on both types of parts very rough. What finishing system would you recommend to smooth our surfaces? Surface refinement of complex shaped 3D printed parts is a good fit for mass finishing. Surface refinement processes take time but are very effective. We recommend higher energy systems to reduce time cycles. There are two machines that work well with 3D part refinement. 1. Highspeed vibratory tub machine (23000 rpm’s) 2. Centrifugal disc high energy systems Vibratory Tub Centrifugal Disc Ceramic tristar media 3D printing produces surface finishes in the 120300 Ra range. With high energy mass finishing, use a fast cut medium sized 5/8 x 5/8 tristar ceramic media. 3D surfaces on plastic and metal parts can be refined to as low as a 16Ra. This will take 68 hrs in the highspeed vibratory tub and 24 hrs in the centrifugal disc machine.

3  D  Printing  part  finishing    We  have  two  3D  printing  systems  that  we  produce  metal  and  plastic  parts.  We  are  finding  the  surfaces  on  both  types  of  parts  very  rough.    What  finishing  system  would  you  recommend  to  smooth  our  surfaces?    Surface  refinement  of  complex  shaped  3D  printed  parts  is  a  good  fit  for  mass  finishing.  Surface  refinement  processes  take  time  but  are  very  effective.    We  recommend  higher  energy  systems  to  reduce  time  cycles.  There  are  two  machines  that  work  well  with  3D  part  refinement.
