Shapeways: Bring your creativity to life in 3D http://www.shapeways.com/forum/index.php Shapeways: Bring your creativity to life in 3D Powder in my ears... literally! http://www.shapeways.com/forum/index.php?t=rview&goto=60753&th=12548#msg_60753 To facilitate wall thickness in my design, I put a 1mm+ hole in the end where the ear connects to the main body.
However, I was surprised that the ears were heavier than my calculations; causing them to droop when assembled.
Ultimately, it was discovered that the ears were filled unfused powder material! I drilled a hole and emptied the contents out which equalled 3 grams of extra weight on a part that should weigh 5.5g.

Not sure if this extra weight is charged to me upon printing, but I'll be making bigger holes whenever possible from now on Shocked

Happy Fabricating,

Now you know first hand about why we require 4mm/ 2mm for two or more escape holes. Best of luck removing and cleaning the powder.]]> Mhagan 2013-01-25T21:10:54-00:00 Re: Powder in my ears... literally! http://www.shapeways.com/forum/index.php?t=rview&goto=60821&th=12548#msg_60821 stop4stuff and Mhagan.
The powder was easily squirted out of the first ear just to show the volume of material trapped in there.
A vacuum made quick work of the second ear Laughing ]]> 8th-elephant 2013-01-26T02:37:10-00:00
