Co-Founder of TeMAAK and Inventor of the RotoMAAK, Mark VanDiepenbos presents the RotoMAAK desktop rotational molding machine and demonstrates its use.
The RotoMAAK evenly distributes 2 part epoxies, as well as other rotational mold materials, to make parts out of 3d printed molds, silicon molds, or other types of molds in as little as 5 to 10 minutes. More details and specs coming soon, including the date for the Kickstarter campaign. Sign up on their website www.rotomaak.com to receive email notifications about its development and Kickstarter Launch.
Mark VanDiepenbos is a part of Makerspace Goshen, the same group that John Oly and Steve Wygant of www.seemecnc.com (Rostock Max and Orion 3D printers) are a part of.
