Production 3D Printing of Metal Components

3D Printed Stainless Steel Metal Parts for Production Runs

If you’re looking for medium-sized production runs of 3D printed stainless steel parts, RapidMade has you covered. Our direct steel 3d metal printing service is the best option for stainless steel and bronze alloy manufacturing in quantities ranging from about 100 to 1000 parts.

This new technology offers excellent value for orders that are too large for other metal printing methods like DMLS but too small for die-casting or metal injection molding.

Direct custom metal 3D printing online bridges the gap between existing technologies by providing a solution with limited lead times that is 10 times faster than DMLS and 8-12 times less expensive for medium-sized production runs. And, because it doesn’t require tooling, direct custom metal 3D printing is more flexible and affordable than die casting or metal injection molding.

Request a quote with our Classic Quote tool or by giving us a call. A RapidMade engineer for steel 3d printers will review your design and send you a price in 24 hours or less. Once your order is placed, metal 3D printed parts made with rapid casting have a typical lead time of 5-12 days.

The Most Advanced Production Metal Manufacturing by Metal 3D Printing Company, in the US

When it comes to medium-sized production runs of metal 3D printed parts, manufacturers are often in a bit of a bind. Die casting and metal injection molding require expensive and time-consuming machined tooling, making them impractical for all but large orders. Moreover, this tooling means that any adjustments to a part’s design are costly and slow to implement.

Traditional custom metal 3D printing online technologies like DMLS, on the other hand, have a very high per part cost, limiting their use to prototypes or extremely short runs of specialty 3D printing of metal parts. While machining produces excellent finishes and tight tolerances, it is expensive for large quantities or complex designs.

Now, you can get production-grade metal 3D printed parts in weeks, not months, and at a more affordable rate than ever. Plus, direct metal printing is compatible with a variety of 3D printed stainless steel and alloy metals, so you can make 3D printing of metal parts to fit a wide range of applications. It’s even a great option for producing durable metal tooling!

Design Advantages of Direct 3D Printing of Metal Components

Direct metal printing affords all of the design advantages of most 3D printing of metal components technology. Complex geometries, nested cores and latticing are all able to created accurately and consistently over many metal 3D printed parts.

This allows new possibilities for combining multi-part assemblies into single pieces as well as reducing part weight by replacing solid blocks with lightweight, durable lattices. Because direct custom metal 3D printing online does not require any tooling, design alterations are easy, even after parts are already in production.

Our expected tolerances are within 1%, though this can be reduced even further in some cases. Additionally, 3D printing of metal parts can be machined after printing to maintain even tighter tolerances.

3D Printing With Metal Design Considerations

When designing parts for direct custom metal 3D printing, there are a few important factors to consider:

  • It is best suited for 3d printing of metal parts no greater than 5″ in their largest dimension.
  • Overhangs over 25 mm (in) must have supports or fillets.
  • Inside corners should have a fillet radius equal to wall thickness.
  • Hollow cavities need a hole to drain loose powder after setting.
  • Thin connections between thicker sections may warp.
Part SizeMin. Wall Thickness
3-75 mm (0.12-3 in)1 mm (0.04 in)
75-150 mm (3-6 in)1.5 mm (0.06 in)
150-200 mm (6-8 in)2 mm (0.08 in)
200-300 mm (8-12 in)3 mm (0.13 in)

Why Use 3D Printed Stainless Steel?

3D printed stainless steel is one of the most popular metals for industrial parts and consumer products. Considering everything it has to offer, it’s easy to see why.

Corrosion resistance, thermal resistance, mechanical strength, sterilizability and good looks—3D printed steel has it all. Plus, it’s affordable and easy to work with.

Direct metal printing opens up an entirely new field of use cases for stainless steel by eliminating cost, quantity and design barriers to economical manufacturing.

Countless industries use 3D printed steel, including:

  • Medical
  • Transportation
  • Energy
  • Appliances
  • Food
