Hello Chang-Shik,Min
We measure every mold using traditional measuring tools. Digital data
collection is an excellent tool as well.
Are you having difficulty finding datum points inside the mold to
begin your inspection? If this is your problem you need to establish
physical inspection set-up points. These points should correlate to
the cavity/core part geometry datums.
Are you using RapidSteel 1.0 (LR1) or RapidSteel 2.0 (LR2)? This will
make a difference. Molds we have made to date in LR2 are flat within
.005".
Kindly,
Jim Williams

Subject: about the measurement of mold built by SLS RapidSteel

Dear all:
There seems to be somebody who knows what the best method
to measure 3D dimension of mold built by RapidSteel is....
I think the dimensional accuracy of mold built by RapidSteel
is relatively inaccurate to be used as an injection mold.
So it is very difficult to define the origin and axis on it.
That is why I've checked the accuracy of the whole mold surface
using 3D laser digitizer(scanner) and then compare measured data
with designed data.
Is there anyone who has other opinion ?
Your ideas will be appreciated...Thank you in advance.
