The ExOne Company, the global industrial sand and metal 3D printers using binder jetting technology, today announced the launch of the ExOne Metal Designlab printer and X1F advanced furnace in an exclusive partnership with Rapidia, a Vancouver, Canada-based technology company founded by Dan Gelbart.

 

Orders are being accepted starting today, with the system printer and furnace available for delivery in the second quarter.

Under terms of this strategic partnership, ExOne has a right of first refusal for majority ownership of Rapidia, and Gelbart will now become a technology advisor to ExOne.

 

Gelbart is an electrical engineer who co-founded companies such as Creo, Inc., a laser technology company sold in 2005 to Kodak for $1 billion, and Kardium, a medical device company. He has been issued 135 U.S. patents for inventions ranging from package tracking technology to atrial fibrillation treatment.

 

Rapidia’s two-step 3D printing technology, developed over several years and first revealed in 2019, was the first to allow water-bound metal and ceramic parts to go directly from a printer into a furnace without a debinding step. The efficiency is made possible by HydroFuse, an innovative water-based paste containing metal or ceramic powders, which does not require debinding before final sintering. Two materials are currently offered: 17-4PH and 316L stainless steels, with other metals and ceramics to follow soon.

The ExOne and Rapidia teams are collaborating on system and process enhancements to offer this true Print Today, Parts Tomorrow to the marketplace, with more innovations expected. The new X1F advanced furnace, with about 10 liters of usable volume, will also be offered across ExOne’s binder jet lineup, where it is an ideal complement to the Innovent+ or InnoventPro 3L or 5L printers.

 

A True Print Today, Parts Tomorrow Innovation

Most other bound metal 3D printing technologies require either three steps (print, debind and sinter) or 3D printing followed by a very slow thermal debinding in the sintering furnace. Either method usually takes 3-5 days to produce a final part and comes with limitations on part thickness, so that the part can properly burn off the polymer binders. Often, these systems limit parts to 5-10 mm (0.2”-0.4”) thickness, which also limits the final strength and applications for the final part.

 

By contrast, the HydroFuse paste developed by Rapidia replaces 98% of the binder with water, which evaporates while printing, enabling true Print Today, Parts Tomorrow technology. This technology also removes the limitation on maximum part thickness. The new ExOne Metal Designlab can print 100% solid metal of any thickness, delivering maximum strength parts suitable for a wide variety of demanding pre-production and end-use applications.

 

The ExOne Metal Designlab will compete directly with other bound metal 3D printing systems, such as the Desktop Metal Studio System 2 and Markforged Metal X.
