I have an idea of using cheap RTV silicones for covering the part and
putting in a regular shape box. The silicone should not be vacuumed or
vulcanised if you can find a quick solidfying cheap silicone.
After covering the part with silicone you can put it in a hard box and
ship to other side of the world. The problem here can be the weight of
the shipment will increase and this will probably affect the price.
But this is only an idea and I did not experienced it.
Wish a nice day to all

I've used the SLA process to build a "nest" of support structure for
I just added the cost of the nest into the quote for the prototypes.
You can automate the process by assembling the parts as they are to be
shipped, and combining them into a single STL file.
If you set the support parameters correctly, you can build the nest with
no saw teeth (and no overlap into the prototypes) to make them fit with
virtually zero clearance around the prototypes.
Create the supports from as many directions as necessary to trap the
prototypes in a rigid structure that can be disassembled.
To get a nest to go completely around a prototype you can create an
additional object for the program to support that is shaped like the
underside of the top surface of the box. The result will be a honeycomb
structure with a cavity shaped like your prototype in it. Split this
structure as needed to allow for assembly.
Box the completed structure in something indestructible so that nothing
can move and you are ready to ship.

It reminds me of 6 grade science class where we had to package an egg in
a box that was going to be dropped from a flag pole. The person with
the lightest packaging won.
I dont think it was me...
Seriously, back when I was at Martin Marietta I had to ship a complex
sensor back to a different lab. In the central warehouse there was a
team of engineers that did nothing but packaging. I assume if you are
going to pack something for transport on the Suttle you really want to
have it get there. But these guys also did design of packaging for far
more mundane jobs like the sensor.
I would think it would not be too difficult to get data on the average
forces experienced in various shipping scenarios and then look at the
survivability of various RP parts. The default shipping method always
seems to be foam peanuts but sometimes the peanuts can actually cause
damage to the part.
Also we have used the RP process to make fixtures to improve shipping
survivability. Could you make that work into your packaging solution?
The solutions we did find for shipping: we may have found a company that
will provide 3rd party insurance for high value fragile items. Will post
it works. Also, air cargo, where you drop it off at the airport and
customer picks it up is very cost effective for large items and reduces
3rd party trucking. However, you do need to be precleared to ship this
way due to new security regulations. Certification takes at least 3
weeks so plan ahead if you intend to use that method.

Kenny / Phill et al
Further to the previous thread on Shipping of parts, etc. and having
just received an undamaged, apparently well-packaged box of 2 urgent
parts (one of which was in 6 pieces, the other in 7 pieces...) I have a
suggestion for a future research project....
How about sorting out a definitive packaging solution for waxes /
delicate layer built parts which more often than not end up broken or
damaged (usually only on critical projects!)
Having witnessed over 10 years of trial and error (as both supplier /
customer) using various combinations of: boxes within boxes, eps
peanuts, bubble wrap, sealed air pockets, inflatable bags, cotton wool,
shredded paper, silicone rubber, ceramic etc. there is still no
comprehensive solution for this as far as I am aware.
Geometry and material are the key variables, and I am sure that list
members could provide some suitable test geometries. (Wax turbine
wheels for automotive diesel turbos for starters).
Potential end result could be a packaging solution for delicate parts
available at a premium. If this could effectively guarantee the safe
arrival of your parts, then it would be worth the extra ($10? $50?
$100?) per shipment.
Am I crazy or would this be best solved by a research project approach?
I am tortured by visions of boxes suspended by springs on all sides that
couriers could play soccer with and still not break the part(s) held
Any comments / ideas welcome.
