The Economics of MIM Versus 3D Metal Printing

Metal 3D Printing is becoming a great complement to Metal Injection Molding (MIM) and the decision to use one or the other largely comes down to the volumes required. The added bonus with metal 3D printing is that you can update a part without needing to invest in a brand new mold.


Manufacturers today who are searching for a cost-effective way to make small and complex metal parts for production by and large only have two options: metal injection molding (MIM) or investment casting. Casting has been around for thousands of years, and MIM was created ~40 years ago.  Metal 3D printing is the new entrant to the scene, and for the first time in a long while adds another option to the engineer's toolkit.  New low-cost, high volume metal 3D printing technologies (like 3DEO) are beginning to change conventional manufacturing wisdom.

New Powder Metal Alloys Added to MPIF Standard 35

The MPIF Standard 35 for powder metallurgy now includes two aluminum alloys in the 2xxx designation series.


The Metal Powder Industries Federation (MPIF) released a new materials standard for aluminum alloys, which will become part of their Materials Standards for Metal Injection Molded Parts publication.

Top 3 Benefits of MIM 17-4 PH Stainless Steel in Firearms Manufacturing

MIM 17-4 PH is a powder metal alloy containing iron, chromium, and nickel. It’s ideal for firearms manufacturers who demand final product integrity, part complexity, and lower cost per part.


1. Maintains Firearms Accuracy with Structural Integrity

In the case of firearms, heat is the enemy of accuracy. Gun models that require steady or repeated discharge, as is the case of many automatic weapons produced for the defense industry, produce heat in the barrel. And that heat leads to expansion of the bore, which, in turn, allows the ordnance to spread. Instead of a tight grouping, a shooter will begin to see looser target patterns.

The Economics of CNC Milling Versus 3D Metal Printing

Cost per part is only one aspect of the economics involved in CNC Milling and metal additive manufacturing technologies. At its core, the decision to choose CNC or AM (or both) comes down to part requirements within a specific application.


If you’ve been researching solutions for metal parts manufacturing, you’ve probably encountered the “either-or” scenario: either metal additive manufacturing (AM) is the best option or CNC milling can’t be beat.

3DEO in the News: TCT Magazine Article

3DEO are, like Desktop Metal, aiming to make metal 3D printing more affordable. And like Desktop Metal and Markforged, they are using MIM powders and a secondary sintering step to achieve that. However the big difference comes in their process, 3DEO describes six steps to achieving a finished metal part that is more affordable and meets the high industry benchmark MPIF Standard 35 while still achieving tight tolerances.
