The EHR is our High Resolution unenclosed printer designed for bioprinting on the desktop or inside of a fume hood.
Technical specifications and accessory compatibility for printers currently shipping are detailed in the comparison chart on the Printer Overview page.
All improvements introduced were implemented to the existing line, obsoleting previous versions (with no price increases):
- The EHR was introduced in 2016, equipped with precision ball screws in all axes. It is able to print in wellplates and fits in most fume hoods.
- We introduced sub-ambient (chilled) beds and syringe heads specifically for the EHR in 2020.
- The EHR v2 began shipping in January 2021, equipped with better motors with closed-loop feedback and quieter operation.
- As of June 2021, all units are CE marked.
