The normal surface finish of FDM parts is suitable for most purposes but in applications where a different finish is required, media blasting is an inexpensive and quick solution. It can be used to achieve the final surface appearance or as a preliminary step for subsequent finishing operations.

I knew it had to be possible, thank you!
This looks pretty good, I think I might have to look into picking up the supplies to do it myself!
Impressive!
Will have to try this with my air eraser.
what type of media was used for this process?
Hey Thomas, in this case a plastic media was used, but there would be different options based on the project requirements.
Blasting media is commonly rated mild to harsh based on a metal substrate.
Aluminum oxide: harshest
Aluminum oxide is the most aggressive blast media for smoothing an FDM part and can also be used to texturize or etch parts. This media is ideal when preparing a surface for electroplating.
Plastic: mild to harsh
For surface smoothing, this finely ground plastic media is recommended. This media is available with abrasiveness ratings from mild to harsh (Figure 2).
Sodium bicarbonate (soda): mildest
Soda is ideal for converting a glossy finish, like that which results from a vapor smoothing operation, into a frosted, matte finish.
@@proto3000_ What about using glass bead at a low pressure? We need to smooth PP so we're thinking glass bead or soda blast media.
do you guyz still have this product in your production line?
We use a range of different finishing systems now
This could put my airbrush compressor to better use!!
Have a before and after shot?
ermmm 0:09?
