The Stratasys F123 series are FDM 3D printers with three varying degrees of performance / capability. They bring fast, professional-grade 3D printing to the office environment, combining the plug-and-play ease of use of a consumer product with the proven and tested results of the technology. The design reflects what the machine really is, a robotic tool. Using a panel and gap theme, it also anticipates the day when the technology will be used to make parts for the machine, and the gaps can tolerate the cosmetic quality of an unfinished 3D printed part.
