Stainless Steel filament

Metal parts with FDM: 316L stainless steel.

Sample part made from Stainless Steel

What is Stainless Steel?

Ultrafuse® 316L is a stainless steel composite filament developed by BASF. Grade 316L is preferred in industrial applications and prototyping for its durability, corrosion resistance and mechanical properties. It makes it possible to produce complex metal parts with FDM.

Debinding and sintering are required after printing. TAİ Robotik takes on the 3D printing stage of the work.

Design guidelines for Stainless Steel

General guidelines for FDM technology. All design guidelines

  • Minimum wall thickness0.8 mm
  • Smallest detail0.4 mm (nozzle diameter)
  • Clearance for moving parts0.3 – 0.6 mm
  • Text and logosEmbossed ≥ 0.6 mm, engraved ≥ 0.8 mm
  • Minimum hole diameterØ 2 mm
  • Unsupported overhang angle≥ 45° from horizontal; flatter surfaces need support

Applications

  • Industrial design
  • Spare part production
  • Custom metal parts
  • Metal prototyping

Advantages

  • Real stainless steel parts with FDM
  • Mold-free metal prototypes and spare parts
  • 316L-grade corrosion resistance

Limitations

  • Requires debinding and sintering
  • ~16–20% shrinkage during sintering; allowance must be designed in
