Forward AM’s Ultrafuse has a narrow shrinkage window of 16-17% on the XY and 19-20% on the Z axis. Using Filamet brand metal filament from The Virtual Foundry, you can plan for the print to shrink about
 5% for copper and bronze, 10% for the steels using the company’s published debind/sinter process. The Z will show expansion if the debind process doesn’t go smoothly, but should shrink just a bit more
than the X and Y in a successful cycle. Overall, normal shrinkage is 7-10%, the company says. Final parts will be 80-85% dense, but parts can be sintered for longer, meaning more shrinkage and higher density.

It’s also helpful to know that Ultrafuse offers a comprehensive user guide
 that includes information on tolerance, shrinkage and scaling, wall thickness, and more.
