The First Step in the 3D Printing Post-Processing WorkFlow is OFTEN Cleaning

May 6, 2021 3:43:10 PM

You can have the best 3D printed parts in the world, but if you do not have a good cleaning/post-processing workflow, your parts are likely not going to look their best or be as functional as possible. This is especially true with powder-based 3D printing technologies. 

The most common cleaning process for powder-based 3D printing is bead blasting.  In the past, this was done manually bent over a bead blaster; you would have a bead blaster hooked up to an air compressor and clean each part one at a time.  This process not only takes time, but you could damage and/or discolor the parts by putting the spray nozzle too close to the part.  See example A for discoloration, called burn marks. Example A Burn MarksIf any of you have ever bead blasted by hand you know what a pain in the back, neck, and eye strain it can be, not to mention a major time suck especially if you have many parts to clean. 

Now with the DyeMansion Powershot C automatic cleaning system what would take me hours has been reduced down to 10 minutes a load.  The other advantage with the DyeMansion Powershot C is I get consistently clean-looking parts.  See example B20210428_155747 The cleaned parts are ready for finishing or shipping depending on your or your client's needs.  Again, remember the advantage of additive manufacturing is cost-effectiveness and turnaround time.  

In the video below, you can see I am unpacking parts from the HP Multi Jet Fusion.  I am just cleaning the loose powder off the parts as the HP recycles the unused material back into the system for reuse.  The parts are then loaded into the DyeMansion Powershot C and cleaned. 

After using the DyeMansion cleaning system, I would never want to go back to the cleaning process manually again.
