Are you looking for new ways to produce metal parts? Do you repair or replace metal parts due to corrosion or wear? Are you responsible for maintaining high-value metal parts? Is it time you added metal additive manufacturing to your company’s capabilities?

Quick Guide to Metal Additive Manufacturing for Industrial Components
Quick Guide to Metal Additive Manufacturing for Industrial Components

Tom Cobbs, Product Manager | Optomec

Metal additive manufacturing has been around for decades now. What was once just an interest in scientific research centers and universities is now being found in use globally at state of the art manufacturing facilities. It is used across many industries, from medical and auto to aerospace and energy. And it continues to grow. As it advances in sophistication and to a more robust and stable processing means, it is rapidly moving from just something of interest by early adopters to full-blown qualification and use in the most demanding of industrial settings.

Metal additive manufacturing is increasingly being considered as a replacement, enhancement, or alternative means to traditional metal part production and repair, especially in applications where parts are vital, costly, and maximizing uptime is a top priority. It can provide huge cost savings and offer dramatic reductions in lead times. Some examples include:

  • Fast building of prototypes or full-scale production parts.
  • New designs not possible with previous manufacturing methods that can light-weight existing products, enhance material properties, and decrease overall material waste.
  • Printing of legacy parts (older parts that cannot be sourced anymore).
  • Decrease the number of manufacturing steps in the building of a product.
  • Repair of high-value parts (repair instead of replace).
  • Immediate printing or repairing of parts that have very long lead times.

These are just a few reasons it is growing in popularity, especially in repair where analysts estimate that nearly $300 billion is spent annually in the U.S. alone due to corrosion or wear.

With so much at stake, it’s important to know more about metal additive manufacturing and the various processes in use today. If you’re a newcomer to the additive world, not to worry, we have a “101” overview of metal additive manufacturing processes to get you started.

First, let’s look more closely at the term additive manufacturing. It is not a new term. In fact, it has been around since the 1980s. Many believe it will be the next industrial revolution. Often additive manufacturing is used interchangeably with 3D Printing (since we are only considering metals here, note that “metal additive manufacturing” is also synonymous with “3D metal printing”). For our purposes, both terms reference the same thing – the process of building parts, repairing parts, or adding features onto existing parts, layer-by-layer from geometry described in a CAD model. Whether you call it additive manufacturing or 3D printing, the benefits are the same: complex parts can be built more easily, more quickly, and cost-effectively with less waste and significant functionality gains.

Taking things one step further, these terms bring up a whole other set of new vocabulary that can be confusing and intimidating to those unfamiliar with the vernacular.

What’s the difference between laser cladding and directed energy deposition? How does powder bed fusion compare to binder jetting? What about Laser Metal Deposition, Laser Engineered Net Shape, (our own LENS™) and Direct Metal Deposition, DMD™, Automated Laser Welding – are these terms all referring to the same process?

We have answers for you. The new Optomec Quick Guide to Metal Additive Manufacturing for Industrial Components provides a succinct overview of the top technology lexicon approaches to metal additive manufacturing according to the ISO/ASTM 52900 Additive Manufacturing general principles and terminology. In addition to Powder Bed Fusion (PBF) and Directed Energy Deposition (DED), which we detailed in a previous blog post about the two most common methods used today for metal additive manufacturing, we describe wire-feed DED, electron beam (EBAM), binder jetting, and outline the advantages and disadvantages of each.

From titanium and copper to stainless steel and other alloys, the quick guide lists typical deposition rates as well as ideal applications for each approach.

Horner Solutions Group - Overall Equipment Effectiveness (OEE)

Horner Solutions Group offers a pre-programmed solution that is fast and easy to implement. No development on the user end, just a simple setup on the touchscreen and you can start monitoring and collecting data in minutes. With the ever-growing need for production data in the industry, we wanted to help bridge the gap for many production companies to be able to start collecting accurate and functional OEE (Overall Equipment Effectiveness) data within just a few minutes of setup, as opposed to the weeks/months many companies spend developing their own solution from scratch. For any customers that may have a need outside of the typical product mold, we also offer engineering services for custom hardware and software solutions of various types.
