Getting Started

Lately, metal 3D printing has gained a great deal of traction in the world of industry. This is primarily thanks to several advancements in the relevant technologies but also because it seems like a game-changer, even for already disruptive 3D printing applications. After all, the global value of industries that rely on metal processing easily exceeds trillions of dollars, and this is an excellent motive for innovative companies to capture even a small segment.

As can be expected, more and more services are appearing that offer metal 3D printing services. They use various technologies, but in general, the starting material is a metal powder. Depending on the process used, this powder is either fused, sintered, or bound together to produce the “raw” version of the object, which must then be post-processed and finished, usually in a special furnace or kiln.

In this article, we will present our pick for the 10 best companies that offer metal 3D printing services. Although the term “best” is subject to interpretation, we used the following evaluations to make our pick:

  • Geographic coverage: A company with fewer geographical restrictions is a strong plus.
  • Available materials and technologies: The more available, the better, as it gives customers the power to choose what’s best for them.
  • Service portfolio: Here, we evaluate the additional services that are offered as well as the variety of metal part services. This demonstrates the ability to serve various different customer groups.
  • Speed of response: The speed of response to a customer’s communication, whether a simple request for information or an order.
  • Pricing (for a sample item): We evaluate the price asked for the same object, made from the same material.

Obtaining a Quote

In general, all services offer an online quoting service or return the quote after human evaluation of the project by a group of experts. Regardless of the method, the workflow is almost the same:

  1. A customer uploads his or her 3D model.
  2. The company or website guides the customer through the desired material and finishing details.
  3. The desired quantity is given, and the price is presented (either though an instant quote or after human evaluation).
  4. The order is placed and the item goes into manufacturing.

Depending on the technology used, post-processing costs may be applicable (normally they will be included in the quote).

Now, let’s have a look at our top performers!

Shapeways offers all major technologies, while their metal printing system uses 3D printers from the aforementioned ExOne.

The technical information regarding their materials is good along with the design guidelines for the models to be printed. Their online ordering system is also friendly and well designed; one can easily upload a model, which is analyzed in real-time before presenting options for materials and finishing. The price is calculated based on these selections and the number of pieces ordered.

3D Systems is one of the “big names” in the industry, partly due to its vast coverage and services, but also due to its history with the invention of SLA technology (and with it, 3D printing). Their headquarters are in Carolina, USA, but they do cover all major global markets.

They offer a large spectrum of services, including hardware and software support. The industries they serve are several, but they seem to pay slightly more attention to industries that require a lot of prototyping or molding.

Metal 3D printing is incorporated into a number of their services. For example, one can find metal printing in the rapid prototyping service as well as the low-volume production service.

Their ordering system is a bit of a mixture. It requires a login (thus prior registration) before being able to request a quote, instant or otherwise. They also offer the possibility to help you design your desired object.

  • Geographic coverage: Almost worldwide
  • Available metals: Steel, aluminum, nickel, and cobalt-chrome
  • Technology used: Metal binder jetting, direct metal printing
  • Service portfolio: Very large
  • Response time: Good

The strength of their technology lies in the production of small and complex parts (like gears for an engine or micro-gears for watch mechanisms). They serve customers all around the globe through a single production site, which is located in Sweden.

Something unique about Digital Metal is that it uses somewhat different materials than other similar services, such as composite mixes of steel and also titanium.

They do not provide an online ordering system, but they follow the more traditional route of allowing customers to contact a salesperson. The client can send a file and then the company’s engineers will provide feasibility and cost information.

  • Geographic coverage: Mainly Europe, USA, Brazil, and Japan
  • Available metals: Steel, iron, titanium, and their alloys
  • Technology used: Metal binder jetting
