3D printing metals is practical

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, n
ormal 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.

DSH has Debinding and Sintering runs scheduled every other Tuesday, on the 2nd and 4th week of every month, and parts need to have arrived to DSH on the Friday before. See the schedule below for the days when they will run any properly packaged and shipped Ultrafuse 316L parts they have received. What counts as properly packaged and shipped parts? Check out our "How to Prepare Ultrafuse 316L Parts for Debinding and Sintering" guide.

BASF Ultrafuse 316L 3D Printing Filament Settings

  • Recommended Print Bed Surface: Dimafix on Glass Bed
    • Alternative Option: Kapton Tape on print bed (preferably on glass)
  • Recommended Nozzle: Abrasion Resistant and clean of any filament that isn't Ultrafuse 316L
  • Heated Bed Temperature: 100 - 120°C
  • Hotend Temperature: 215-235°C - Never to exceed 250°C.
  • No Part Cooling: Layer cooling can cause warping during printing
  • Recommended Layer Height: 0.10 - 0.25mm [.15 or lower for higher density]
  • Recommended Speed: 15 - 40 mm/s
  • Infill: 100% - We recommend either Lines or Concentric pattern depending on your geometry. These will give you the most uniform and solid infill. Any gaps or voids in your infill could lead to failure during the debinding and sintering process.
