The restriction of having no loose parts in a model is restrictive and greatly reduces the quality and ease of certain models. And don't tell me the printing process can't handle it - I've used 3D printers before and they are designed to be able to create intricate models with various independently moving parts. I'm trying to design a model with some small and intricate pieces in it, and it's a major b***h trying to work out ways to assemble the model without using glue (which wouldn't hold on stainless steel very well, and even if it would, the pieces I'm working with are quite small, it would be very annoying to hand glue them together).

Long story short, I don't understand why the rule is no loose parts. 3D printers have the capability to do that - in fact it's one of their major advantages, that models can be printed already assembled, instead of in pieces to be assembled later.

Some print systems can, others not at all (or not without some postprocessing, which SW doesn't offer). Check the material info pages, the table in the Design Guidelines tab of each material. Watch videos about how each machine works.

The steel-bronze puts the bronze by infusion, so all parts must be connected to let the molten metal get everywhere. The silver is done via investment casting, and a loose part would mean no path for the wax to escape or the metal to enter. The best you can get is add connections and then remove them upon arrival (the step SW doesn't offer).

On the other hand, people print chains in WSF every now and then, without any extra steps.

Hmmm, I see. Seems an awful shame to add a connection and pay for that volume when you're just going to break or sand it off anyway, though.

Right, guess it can't be helped. Hopefully a new method is developed, eventually, but it's still new. Thanks for the reply!
