Nexa3D Announces Intent to Acquire Essentium; Adds High Speed Extrusion to its Product Portfolio
Nexa3D, the ultrafast 3D printing leader, has taken a significant step in staking its leadership position in the industrial additive manufacturing space by signing a letter of intent to acquire Essentium, a prominent manufacturer of HSE 3D printers and materials, widely adopted for high requirement, precision applications in aerospace, military, and defense. With this acquisition, Nexa3D would add high-speed extrusion (HSE) to its current product portfolio.
Essentium, renowned for its broad materials portfolio, award-winning high-speed extrusion 3D printers and true independent dual extruders (IDEX), has carved a niche in the industry by providing solutions for complex polymer production applications that are 5 to 15 times faster than competing extrusion technologies. The company’s commitment to innovation and reliability has made it a go-to choice for manufacturers and government users worldwide.
This marks the beginning of an exciting collaboration that promises to revolutionize the 3D printing landscape. The combination of Nexa3D’s expertise in ultrafast 3D printing with Essentium’s mastery of high-speed extrusion technology will result in a powerhouse of production technologies, ultimately benefiting industries ranging from aerospace and defense to medical devices and consumer goods.
Dissolving Molds: A New Way to Think About Injection Molding
Rather than mimic the conventional functionality of a tool, something new is in the game: dissolvable molds. The soluble tooling technology uses the same printer but different materials, allowing for a flexible workflow—from geometry to molds to parts.
The dissolving aspect provides design flexibility, Mason notes. Even for complex parts with undercuts and non-ideal parting lines, the mold design can be completed in 30 min., which eliminates the need to anticipate and address the pain points of a part before testing it. Mason says the speed of this approach is exceptional and molds are ready to use in less than an hour.
The dissolving aspect allows for experimentation and testing. Unlike traditional molds where changing the gate location can be costly, using the 3D printing process means each shot can have a different gate configuration. Mason says this is a liberating feature that enables a multitude of design iterations with minimal time and material costs.
Nexa3D acquires Addifab
Nexa3D, a specialist in ultrafast polymer 3D printing hardware, has completed the acquisition of Addifab, the originator of Freeform Injection Molding, a proprietary and patented digital tooling process that couples the design freedom of 3D printing with the mechanical performance of injection molding using thousands engineering materials.
Rail Giant Alstom Turns to Nexa3D’s NXE 400Pro to 3D Print Replacement Footrests
Alstom, one of the largest railway companies in the world, faced trouble with finding replacement parts first hand when outdated footrests threatened to sideline many of its fleets. The company needed a way to fix its trains quickly, and do so in a cost effective manner. Alstom’s solution? 3D printing. The business sought Lorenzo Gasparoni, its 3D printing and 3D scanning product leader in Italy, to establish additive manufacturing (AM) practices to help keep its aging trains operational while reducing the time needed to service the carriages.
Alstom is no stranger to 3D printing and had previously partnered with BASF Replique and Stratasys to use AM to solve sourcing issues in the past. This time, however, it wanted to stay internal to its manufacturing and service center in Sesto San Giovanni, Italy, and needed Lorenzo Gasparoni for the job. The two have been in working together since 2019, but, in mid-2022, a new project arose: the use of 3D printing to produce hundreds of footrests to replace older counterparts.
