Markforged Sinter-2 — Technical data

The Sinter-2 is the large sintering furnace of the Metal X System and, since the Sinter-1 went out of sale, the remaining furnace in this process. It sinters debound parts from the Metal X and FX10 at up to 1300 °C under argon or argon-hydrogen; its 12,135 cm³ working volume is about four times that of the Sinter-1, so several build plates or larger parts fit into a run of about 30 hours. It is thus designed for shops with several printers or higher part throughput.

The Sinter-2 weighs 350 kg and needs a three-phase 30 A supply, an exhaust of 100 to 150 CFM and a fixed gas supply – moving it in and installing it should be planned before buying. On a used furnace, check heating elements, insulation, seals, gas control and the cycle log. It is also worth asking which sintering profiles for which materials are stored and still current.
