Israeli startup takes 3D printing out of the workshop and into the factory

In America, where dentists are turning to digital technology to provide better services for patients, refrigerator-sized machines created by Israeli startup Nexa3D print dental retainers, night guards and other accessories that used to require multiple molds of patients’ teeth and hours of lab work. The new method is faster and often results in better-fitting products.

Nexa3D’s NXE400 ultra-fast printer increases productivity by 20 times compared to competitors and is set to transform 3D printing from a tool for prototype designers to a fully fledged industrial machine operating at production scale. The step change promises to transform the 3D printing industry in the same way broadband internet replaced dial-up.

Dentistry is just a small part of Nexa3D’s business, which spans carmakers, entertainment and industry. In a matter of hours, Nexa3D’s printers in factories around the world, aided by innovative software, transform soft resin into car parts, protective face shields, drones and countless other objects.

When BMW opened its Additive Manufacturing Campus in June 2020, a NXE400 was prominently on display

Additive manufacturing is already an integral part of our worldwide production system today, and established in our digitalisation strategy,” said BMW’s Milan Nedeljković. “In the future, new technologies of this kind will shorten production times even further and allow us to benefit even more fully from the potential of toolless manufacturing.”

The sector is becoming a hot target for investors. Desktop Metal, which specializes in 3D printing of metal and composite parts, went public via a $2.5 billion SPAC in December and is now valued at more than $5 billion. Two more companies, 3D Hubs and EnvisionTEC, were acquired in January 2021.

German manufacturing giant Siemens signed a partnership deal with Nexa3D in September, and will soon begin integrating the printers into its factories.

“We are very pleased to join forces with Nexa3D and together unleash the power and potential of our products to create more resilient and sustainable supply chains,” said Tim Bell, head of Additive Manufacturing at Siemens.

Trumpf set to combine tech for new metal 3D printing systems

Last week we brought you news of Trumpf’s intentions to unveil a new 3D printing technology for the additive manufacturing of metal parts at formnext powered by tct from November 17 to 20, but this morning further details have been announced that showcase the might with which the German-laser manufacturer are entering the business.

The company, which employees in excess of 10,000 people with sales over €2bn, will showcase machines that user powdered metal laser metal fusion (LMF) technology that is popular with manufacturers such as Concept Laser, EOS, 3D Systems and SLM Solutions as well as a machine that uses laser metal deposition (LMD) technology used by the likes of DM3D and Norsk Titanium.

Both of these crucial metalworking technologies are included in the new TRUMPF product range. To achieve this, the company has established a new division at the headquarters site in Ditzingen and has been working even more intensively on new systems for 3D printing. The results and developments derived from the joint venture founded together with Italy’s largest laser system maker, the Sisma company, have supported the efforts carried out by TRUMPF in Ditzingen. The technology behind the new 3D printers is also known as additive manufacturing. In this process component parts are generated, layer by layer, from metal powders. The system uses data taken directly from the CAD program.

“The introduction of these new 3D printers is an essential first step, since additive manufacturing will not only supplement production techniques in the future, but will also exert a formative influence on them,” explains Dr.-Ing. E.h. Peter Leibinger, Head of TRUMPF Laser- und Systemtechnik GmbH. “We will be offering rugged and highly productive machinery with which small and medium-sized parts incorporating complex structures can be manufactured,” Leibinger adds.

Every technology skill in a single location

Market demand is growing for 3D printers generating metal components suitable for use in the industrial environment. TRUMPF is the world’s only manufacturer to have both of the pertinent technologies – LMF and LMD – in its product range. The choice of the process best suited will depend on the details of the specific application. LMF systems generate parts layer by layer in a bed of powder. These printers bring their strengths to bear when making up parts which are geometrically complicated and extremely elaborate. In LMD systems, the laser creates a melted pool on the surface of a part and fuses the powder, added simultaneously in a powder stream, to achieve the desired shape. LMD systems are distinguished by the fact that they can add closely defined structures to existing tools and components, doing so at high processing speed.
