China3D printingNet October 9th, battery3D printingExpert Sakuu Corporation announced the end of follow-up financing, and its total capital raised to 62 million US dollars.
The company aims to use its new investment to fund the launch of the first-generation solid-state battery (SSB) in the second half of 2022 and the second-generation battery 3D printer to be released in the future. Compared with existing lithium-ion batteries, the company’s second-generation batteries have twice the energy density and 30% weight, and have potential residential and industrial applications, including energy storage, microreactors, and electronics.
“I am very grateful for the continued support of our investors,” said Robert Bagheri, CEO of Sakuu Corporation. “This funding will enable us to achieve our main goal: commercialize the world’s first true multi-material, multi-process additive manufacturing platform, expand our R&D team, and continue to develop advanced materials and breakthroughs. Source device.”

Use Sakuu for battery 3D printing
Sakuu, formerly known as KeraCel, is an SSB manufacturer supported by Musashi Seimitsu and has been touting its technology for electric vehicle (EV) applications. After the name change earlier this year, the company launched the Sakuu AM platform, a multi-material system that can combine binder jetting and powder bed 3D printing to process multiple ceramics and metals in the same part layer.
In doing so, it is said that storage devices produced by 3D printers have better interfaces and stronger ceramic layers than existing batteries, while containing monolithic layered batteries that are easier to mass produce.
Since the announcement of the “Alpha” version of its 3D printer in May 2021, Sakuu has obtained three new patents that can further improve the efficiency and flexibility of its SSB production process. These include a novel hybrid solid-state design that has the potential to produce faster rechargeable batteries, and an electrophotographic-based 3D printer that can increase its manufacturing speed and accuracy.
The company also started building a pilot battery 3D printing facility to demonstrate the feasibility of its technology and use them to create samples for its Early Access partners. Once completed later in 2021, the complex will initially produce up to 2.5 MWh of SSB per year, and will expand its manufacturing scale through the Sakuu AM platform fleet in 2022, with annual production capacity of up to 1 GWh.
Sakuu continues to praise the potential electric vehicle application of its 3D printed battery. The photo is from Sakuu.
Bring “SSB” to the market
After the financing round ended, Sakuu stated that its AM platform is still “expected to change the world of active device manufacturing.” The company said that in the past year, the energy density of its first-generation battery has increased from 40Wh/l to 600Wh/l, the number of batteries has increased from 1 to 30, and the capacity has increased from 2.3mAh to 3000mAh, making it “very compatible with Current lithium-ion batteries are competitive.”
Sakuu also 3D printed a saleable version of its first-generation battery and its second-generation “ASSB” demonstrator, which is expected to accelerate the adoption of SSB in electric vehicles and other places when it is fully produced in 2023.
At the same time, in its pilot facility, the company developed the first-generation samples in cooperation with Honeywell and related industries and shipped them to undisclosed “key partners.” Not only does this enable it to acquire “bulk SSB promise” customers for electric vehicles and mobility, but Sakuu says it can now commercialize in a way that “cross-competitive technology” and “far ahead of its peers.”
“We are expanding our business to support our trial line and preparing for the commercial launch of the Sakuu 1000 AM platform, which will enable our customers to unlock breakthrough products and achieve industry-leading performance indicators on multiple parameters,” Bagheri Added.
“With additional funding, we are happy to continue to develop our AM platform to support our strategic customers and early access partners.”

China3D printingNet Comments: Although battery 3D printing is still an emerging technology to a large extent, its development and commercialization have advanced by leaps and bounds in the past year. As early as June 2021, Blackstone Resources, whose subsidiary is said to be developing a method for 3D printing lithium-ion batteries, announced that it was considering listing on the American Stock Exchange.
British 3D printer manufacturer Photocentric also established a dedicated battery research and development department responsible for designing its own energy-saving storage devices. According to reports, the company aims to develop economical fuel cells for Tesla’s upcoming Giga plant through 3D printed electrodes that are smaller, lighter, and more suitable for automotive applications.
Similarly, in the academic field, researchers at the California Institute of Technology (Caltech) have developed a DLP 3D printing method for lithium-ion electrodes that demonstrates enhanced battery performance. Using their new technology, the team has been able to create complex polymer structures that can be used as stable anodes and cathodes.
