Recently I designed some flowers posted here

The stems i designed are simple tubes with internal diameter of 2.1mm , wall thickness is 1.1mm. The tube has printed correctly. It appears to have a hole running all the way through (I can drill to the length of the bit , and the material removed was in powder form).

After a few different attempt im still unsuccessful in removing the powder deeper within the tube.

My question is :
What is the minimum internal diameter for not only printing a tube but being able to clear it with ease?

Since SLS parts have a somewhat hydrophobic effect would bathing in something like Isopropanol help loosen the powder more?

Kind regards

Oh i got a new camera, and took this photo ..... shame to waste it Wink

Hey Micheal
I tried compressed air with no luck.......that said if i had a finer nozzle on the air gun (something similar to a can of compressed air or a WD40), lowered the PSI and tried that way it may work. Will give it a go.

Since i havent figured out the stems I used the Shapeways box to hold the fiber optics in place and block any unwanted light.....worked surprisingly well Rolling Eyes

Thanks

Yea, that's what I would get. A can of compressed air. Maybe try a pipe cleaner? The tiny ones you can find at a craft store or something.

Havent tried them but I assume that if a .5mm wire cant shift the blockage.

I forgot to take them into work today so will test the Isopropanol to see if it can loosen the powder and then try the pipe cleaner idea.

Thanks Micheal

Some people reported freezing allowed them moving apparently stuck parts. Maybe it works for holes too.
