Hi,
Short question: when I want to print a Pendants out of metal, how thick should be a ball with 25mm diameter?
What machine do you use to print that?
Or you’re doing lost PLA?
What kind of metal?
If the ball is being made via lost-PLA, it won’t have a wall thickness.
It’s unlikely that the ball will be of a metal, such as lead, lacking structural stiffness. Even aluminum, formed into a sphere will have reasonable strength with a 1 mm wall thickness, but not if it is expected to take point impacts.
Pendant implies jewelry which is often handled carefully. Silver is soft, so if that is the material of use, at least 2 mm wall should be strong enough for jewelry. Too thick means too expensive in that example.
Other metals, other than gold, are going to have greater strength than silver or aluminum, but also may be more difficult to work.
Daniel Kruger’s question is likely the most important to answer.
I’m going to print it via shapeways. They offer allot of materials for jewelry. I’m still not sure which one. Bruss looks also nice.
This kind of material is not really printed. They print a mold and fill the fluid metal inside.
