Media Tumbling guide HERE
- We use the Bel-Air FMT-06 tumbler with their Ruf-7 cone media
- We will tumble for a minimum 60 minutes, or until the rough “sugar cube” like granular texture has been worn smooth.
- Individually bag all dyed parts so they don’t damage each other in shipping
- Do not let your machine warm up for longer than a few hours
- Ensure you have simple and clear communications between you and the customer, and are on the same page. (This applies to every process)
- Be aware of the constraints while setting up a build.
- Make sure build time fits within your schedule.
- Try to stay under 8% density.
- Orient 10° off of recoater in order to prevent drag and short spreading.
- Bottom part should always have a soft stepping on the bottom for a smoother part.
- If your part is shaped like a cone, print it face down, as it helps anchor the part.
- Check for vertical lines while printing
- Let your builds cool for as long as you can.
- When removing a hot build, keep as much powder on the part as possible in order to prevent it from cooling too fast.
- When opening holes, dip the drill bit to prevent part from overheating.
- Don’t try to fix the warping until all processes (such as dyeing / media tumbling) are done, as it will just warp again.
- Powder that sticks to the surface of parts MUST be thrown away, not recycled.
In the event of a machine crash, you must throw away all the powder within the machine, as it will be thermally damaged.
