Hints for reflective objects

Postby JThompson » Fri Jun 22, 2012 10:30 am

:idea: Hi Fellow Designers, Scanners and Engineers
I have read on various posts that reflective surfaces are causing problems.
i was taught a little trick some years back when taking photos of shiney metal pats.
rub silicone grease/vaselene onto the part, this stops the light reflecting in such a way as to affect the camera.

If someone tries it and has success, will they please feedback their results

The 'opportunity' I have is that I have clients that need high resolution (<0.005") on metal parts so the coating needs to be very thin and not 'fill-in' small details.

Hi Dan,
You could try silicon grease spray (comes in aerasols)

If you are in the US - Magnaflux Spotcheck SKD S2 Developer is the "standard" that all the 3D Scanning studios use.
It is an ultra fine white powder that goes on wet and drys almost instantly and washes of easily with warm soapy water.
Note: there are a "few" caveats ...
extremely high VOC content - spay OUTSIDE or in well ventilated room or you will pass-out !
It will craze/crack some paints and plastics so do a pre-test on a hidden surface BEFORE going on an all out spraying spree ...
