Stratasys J835 — Technical data

The J835 is the middle model of the J8 series between J826 and J850. Its external dimensions, weight and print modes match the J850, but the build volume is smaller at 350 × 350 × 200 mm. Up to seven base resins can be combined in one job, plus a fast mode at 55 µm layers for simple concept models. It is used for colourful multi-material prototypes and design models with realistic feel. Stratasys no longer sells the J835 and only supports it; the current catalogue lists the J850 Pro and J850 Prime.

As with any J8-series PolyJet printer, buyers of a used J835 should check print head condition and hours, UV lamps, wiper and waste container, and maintenance logs. At 430 kg and 1.4 m wide, door and floor dimensions matter. Also clarify how long spare parts and service are guaranteed, which materials the installed software still allows and whether the material cabinet is complete.
