TIPS WITH TONY: Prototyping with Hard Metals

Last week we discussed prototyping with soft metals like aluminum, copper and brass, so this week we turn our attention to hard metals and processes (3D printing, CNC machining and injection molding) used for rapid prototyping in low volumes.

Hard metals that are offered in three different manufacturing processes at Proto Labs: direct metal laser sintering (DMLS), CNC machining (CNC) and metal injection molding (MIM).

Stainless Steel
Stainless steel (SS) is one of the most widely used metals in our material library and is available in three different grades and all three services: 3D printing, machining and molding.

  • 304L is only available for machined parts and offers a higher tensile strength and good corrosion resistance while offering a slightly lower price than other stainless steel materials.
  • 316L is available in machining, industrial 3D printing through direct metal laser sintering (DMLS) and metal injection molding (MIM). 316 offers an improved corrosion and chemical resistance over 304 while offering a high temperature tolerance.
  • 17-4PH is also available in all three manufacturing methods and offers a higher yield and tensile strength with good resistances to corrosion. 17-4 also offers a higher magnetism of all our SS offerings.

NEW JOURNAL: Pitting Manufacturing Processes Against One Another

In the cover story of our current issue of the Proto Labs Journal, we pit manufacturing processes against one another.

As you know, the manufacturing industry is peppered with prototyping and production processes that share some common attributes, but also some notable differences. Our manufacturing “bouts” explore how several of these processes — big and small — compare. The fight card includes:

  • Magnesium Injection Molding vs. Magnesium Die Casting
  • Stereolithography vs. Fused Deposition Modeling
  • Direct Metal Laser Sintering vs. CNC Machining vs. Metal Injection Molding

Beyond our cover story, read about Sean Doan, a long-time Proto Labs employee who is the go-to person in our R & D division; the latest in innovation and advanced technology we’ve mined from the Internet; and new service offerings at Proto Labs.
