BOSTON--(BUSINESS WIRE)--Desktop Metal (NYSE: DM), a global leader in additive manufacturing technologies for mass production, today unveiled FreeFoam™, a new family of photopolymer resins that produces durable and dimensionally accurate closed cell foam parts without tooling – delivering all-new benefits for the automotive, furnishing, footwear, sporting goods, health care and other industries.
FreeFoam will be on display June 28-30 at Foam Expo North America in Novi, Michigan. Automotive seating 3D printed in FreeFoam, developed in partnership with Camaco, an engineered seating solutions supplier, will be on display in Booth 2336.
Parts made with FreeFoam are already being manufactured with leaders in the automotive and furnishing markets, with broad commercial availability of FreeFoam material slated for 2023. A new video showing the process for 3D printed parts production using this innovative new material is now available at https://learn.desktopmetal.com/freefoam.
“FreeFoam is one of the most exciting and commercially significant photopolymer solutions to come to market in the industrial printing space in years,” said Ric Fulop, Founder and CEO of Desktop Metal. “The market for conventionally manufactured foam has many challenges – from expensive molds that limit designs, to dense and heavy foams that absorb water and are expensive to ship and drive, to the inability to easily dial in strength and Shore hardness values in specific foam designs.
“We’re especially excited to reveal our FreeFoam innovation in Metro Detroit, where our new foam material can help lightweight cars and trucks while preserving the performance and comfort expected in foam seating. With FreeFoam, Desktop Metal is ready to liberate the foam market from its many challenges.”
Several Grades of FreeFoam Resins Planned
FreeFoam was invented and developed by Texas-based Adaptive3D, a subsidiary of Desktop Metal that was acquired in 2021 and is a leader in premium photopolymer and elastomer development.
FreeFoam resins are 3D printed similar to other photopolymer resins using DLP. After 3D printing, FreeFoam parts can be expanded on-demand during a brief heating cycle in an oven at approximately 160-170°C (320-340°F). The printed parts contain dispersed heat-activated foaming agents that create closed cell pores inside the material. This highly controllable process causes FreeFoam resins to consistently expand 2 to 7 times their as-printed sizes depending on the grade of resin, achieving final parts within desired tolerances.
This all-new process allows 3D printers to produce much larger final foam parts than the printers’ original build areas and will enable foam products to be shipped at compact sizes and expanded at the final point of assembly or commercial use.
While preliminary specifications for FreeFoam are now available, Desktop Metal plans to offer several grades of FreeFoam resins enabling different Shore hardness values and other specific materials properties such as water resistance for the outdoor furnishing market.
FreeFoam is part of the recently launched DuraChain™ category of one-part, one-pot photopolymers that delivers breakthrough elastic and tough material properties through a Photo Polymerization-Induced Phase Separation process. When illuminated during DLP printing, these materials phase separate at the nano level into a material that cures into a resilient, high-performance polymer network. DuraChain enables FreeFoam parts to be foamed with control in an oven without a mold.
FreeFoam will initially be 3D printable exclusively on the ETEC Xtreme 8K top-down DLP system from Desktop Metal’s polymer 3D printing brand. Companies interested in this new material and process are encouraged to visit https://learn.desktopmetal.com/freefoam.
