Debuted at the TCT 3Sixty exhibition in Birmingham, the SLS machine is designed for use in office spaces and workshops, proving an accessible method of 3D printing durable polymer parts.
The latest version of Gravity comes complete with several hardware and software upgrades that improve the usability and print quality, allow for easier cleaning, and save time for users.
Robert Kniola, founder and CEO at Wematter, said, “An important part of my vision for Gravity has been to create an SLS 3D printer that is as natural to use in the office as your printer for paper. With these new improvements, I think we are more or less there.”
Lowering the barrier to SLS adoption
Wematter was founded in 2014 and has based its entire business around making SLS 3D printing as accessible as possible for professional designers, engineers, hospitals, and manufacturers.
The company’s founders, Robert Kniola and Henrik Lundgren, actually come from a traditional manufacturing background working with injection molding and milling, but also have experience with FDM, SLA, and PBF technologies. Before establishing Wematter, they identified a gap in the market for ease-of-use-focused SLS 3D printing.
While Gravity is the firm’s nucleus, Wematter also offers a number of peripheral hardware products to supplement the additive manufacturing workflow. This includes Atmosphere, a build chamber control device designed to create a more stable thermal environment for Gravity, and Density, a post-processing cabinet that uses a water jet to clean 3D printed parts.
Kniola adds, “For the first time, employees can easily print components themselves with the same strength and quality as traditional technology. Wematter’s proprietary end-to-end solution enables customers to accelerate product development and in-house volume production.”
The Gravity 2022 Mk II
The latest iteration of Gravity sports a build volume measuring 300 x 300 x 300mm, a part precision of 0.1mm, and a compact footprint of less than one square meter. Equipped with a robust double-shielded metal frame, the machine also offers a patented automatic leak-free powder refill system and active carbon HEPA filters for safe and comfortable indoor operation.
On the hardware front, Wematter has developed a new water cooling system for more efficient thermal regulation, as well as a new internal protective window that streamlines the cleaning of the machine between builds. The processing chamber has also been revamped with a better thermal design, enabling larger parts to be printed with greater success.
On the other hand, Gravity’s Deep Space software has been upgraded with an all-new detail preservation algorithm capable of intelligently automating a number of process parameters to improve print quality. All customer support tickets are now handled via the Deep Space interface for a smoother experience, and OTA connectivity allows Wematter’s service technicians to monitor and control printers remotely without the need for third-party tools.
The list of materials compatible with the system has also been expanded to a total of 18 (18 versions across six polymers).
