That's not what's typically done. A 4-40 screw is a machine screw mainly designed for metal. You can tap #4-40 threads in Shapeways polyamide, however, threads that small are going to be problematic. At best, you'd want to leave the screw in there to prevent the threads from getting damaged. What you can do is use a rotatory tool with a cut off wheel and make the screw into a self tapping screw and then just leave it in place once in stalled. If you have a 4-40 tap you can tap threads, but you need to be very careful that you get the screw started correctly or you could crack the polyamide or damage the threads to the extent that the screw doesn't hold. All of this will work if you're just doing a one off and you are highly skilled at correctly doing things like this the first time you try it.

Now, here's how it's done if this is not going to be just an one off or you don't want to run into issues. What you want is something like these 4-20 or 4-24 screws specifically designed for plastic. The thread profile on these are designed to help prevent cracking the plastic. These will work for a few times of installing and removing the screw. Or, if it will be a situation where the screw needs to be installed and uninstalled numerous times you will want to use thread inserts and go with your 4-40 machine screws.

Let us know how it worked out! :D

Or how about Shapeways polished Strong and Flexible and then electroforming in copper and electroplating with brass, gold or rhodium.

Yeah, aluminum would be good too, maybe sandblasted or just left raw for the 3D printed look. Also, it can be anodized.

Has anyone tried polishing Shapeways aluminum yet?

@Ryan H - I too design in ACAD, but so far (touch wood!) all my uploads appear in the same orientation that I had when they were exported to STL. Are you sure you haven't been fiddling with different UCS settings? I find the Z axis in the STL file (and thus the SW render) is whatever the Z axis is in the active UCS when I exported. Still doesn't prevent the SW techs from spinning my models around for their own reasons though...


No, it's nothing like that. I start with a "blank" model and make a copy 5 inches up in the Y axis and make door and window modifications, then repeat for the next variation on and on for 20 or so variations. All the nearly identical models lie side by side like soldiers in the drawing. When all the variations are done I export them in order using the stlout command, one right after the other. So there's no opportunity to change any settings. I don't understand why it happens but it does. Maybe the drawing is corrupted.
