3D Printing in Stainless Steel
We are pleased to offer low-to medium volume metal printing using a binder jet system. Primarily used for production parts, this 3D print technology replaces traditional machining and metal fabrication methods for highly complex parts that can not be easily manufactured. It is also a convenient option for prototyping and short runs when the urgency of the need necessitates a turn-time that can't be supported by traditional manufacturing methods due to tooling lead times and supply chain backlogs.
Binder Jet Material Options (current offerings)
17-4PH Stainless Steel

As with all additive manufacturing, the cost of 3D metal printing is a factor of (a) the time it takes to print and (b) the cost of material used. Slower print speeds make the cost of 3D metal printing significantly higher than other 3D print technologies such as Multi Jet Fusion, therefore the ideal part size for metal printed parts is approximately 3.5" in diameter or less. Very small and very complex parts are ideal for this technology.
Design tips for binder jet printingPart size: for best results in printing and sintering, limit the part size to 150 x 100 x 50 mm (X, Y, Z)
Maximum wall thickness: For successful removal of binder during the debindstep of sinter, limit maximum wall thickness to 25 mm (not to exceed 25 mm in more than two axes) Minimum wall thickness: Wall thickness under 0.75 mm results in insufficient strength in the brown part. Thicknesses between 0.75 mm and 2 mm may still be very fragile during the depowdering stage and will require delicate handling to avoid breakage. When possible, please design wall thickness to exceed 2 mm. Aspect ratios: Aspect ratio requirements are split into two categories depending on wall thickness: Wall widths <1mm not to exceed 4:1 Wall widths >1mm not to exceed 8:1 Additional design considerations are included in our FREE DESIGN GUIDE.
