Levity 3D: RLP’s Liquid Suspension 3D Printer Set to Launch in 2026, Poised to Disrupt the Industry

Rapid Liquid Print, a company spun out of MIT, unveils Levity™—a gravity-defying, sustainable 3D printing platform for elastomers

Rapid Liquid Print (RLP), an innovative startup incubated by MIT’s Self-Assembly Lab, has officially announced the upcoming launch of its groundbreaking 3D printing platform, Levity™, slated for commercial release in 2026. Leveraging a reusable water-based gel as its printing medium, this revolutionary system enables true support-free printing in suspension, positioning Levity as one of the most disruptive 3D printing technologies to watch in the coming year.

“We didn’t just build a machine over the past five years—we’ve reimagined the logic of manufacturing.”
— Schendy Kernizan, Co-founder & CEO of RLP

No More Supports: Just Print, Rinse, and Done

Unlike traditional 3D printing processes, Levity utilizes a unique liquid suspension printing method, where parts are printed directly within a water-based gel medium, forming “in mid-air.” Once printing is complete, the object is simply rinsed with water, with no supports, curing, sanding, or post-processing required. This approach drastically reduces material waste, labor, and production time.

The suspension gel used during the printing process is non-toxic, environmentally safe, and reusable. Each batch can last for weeks and is biodegradable with no harmful emissions, emphasizing sustainability at every stage.

Focused on Elastomers: Functional Parts with Variable Hardness

Levity currently specializes in printing silicone-based elastomer materials, supporting a Shore hardness range from 00-50 to 50A. Thanks to its real-time material blending system, it can even produce multi-durometer parts within a single print job. This makes Levity ideal for applications requiring soft, flexible, and complex geometries, such as medical devices, prosthetics, and wearable technology.

Supported materials include:

  • Platinum-cured silicones
  • Polyurethanes
  • Photocurable elastomers (under development)

 

VEER™ Slicing System: Rethinking Print Path Logic

Traditional slicing software is incompatible with Levity’s non-planar, spiral-based print paths. In response, RLP developed VEER, a proprietary slicing platform designed to handle complex fluid dynamics and live material mixing, enabling high-speed, continuous printing without sacrificing geometric precision.

VEER also supports intelligent path planning and non-linear layer thickness control, resulting in smoother surfaces and eliminating traditional layer-based textures.

Real-World Adoption: From BMW to Haute Couture

Levity is already being piloted with industrial leaders like BMW, enabling tool-free, low-volume production of complex parts. In healthcare, it enables rapid fabrication of customized prosthetics and air-inflatable medical structures. In design and fashion, Levity made headlines by helping Coperni create a printed hollow handbag showcased at Paris Fashion Week.

RLP is pursuing a hybrid business model, offering:

  • Service bureau printing
  • Full equipment sales
  • Application-specific development support
