Finland-based bioprinting startup Brinter has announced the launch of a new extrusion-based Visco Bio medical printhead for its bioprinters. New modular printheads introduced in close collaboration with Puredyne, who provides innovative technologies to the market, allow waste of expensive medical grade materials to be kept to a minimum. Visco Bio printheads offer greater material diversity for dispensing, repeatability with a continuous and precise printing process and mean zero cross-contamination due to the use of a single cartridge per material. Due to the dispensing geometry, a constant volume per revolution is always conveyed and precisely applied, meaning almost zero dead volume can be achieved. Visco Bio also ensures programmable suck-back and clean start and finish points.
Visco Bio is a new step in the printing of personalized treatments
Brinter CEO Tomi Kalpio said; “The release of this printhead means that basic requirements towards Good Manufacturing Practices (GMP) are met, for example, due to no cross-contamination with the use of a single cartridge per material, used together with the disinfecting blue light module we published in December”. Kalpio noted that likewise, researchers, the pharma industry, and universities benefit from the repeatability of printing results being increased due to continuous and precise printing processes. Kalpio relayed that the practical applications of the technology align with Brinter’s vision to improve our quality of life by shortening and enhancing the productivity of the scientific discovery process and bio-manufacturing and disclosed; “This pushes forward the ambition of printing human spare parts such as hearts and kidneys, as well as more personalized treatment through cancer research and drug testing.”
Brinter’s modular bio-printer Brinter One is able to print multi-material and highly complex tissue structures in 3D and provides all the basic features needed for bioprinting. The bio-printer, capable of printing on many hard and soft materials, including living-cell liquids and hydrogels, bio-paste, metal and plastic with binder materials, can be easily packaged and set up in a different lab or cleanroom in minutes.
Puredyne Business Development Manager Felix Gruber expressed that Brinter is an innovative and strong partner for them and that they already have had a close relationship for some years. Gruber relayed that the Puredyne® printhead with its involved progressive cavity technology enables a totally new precision in extrusion-based bioprinting. Gruber also added that their solution gives the operator the required process and material flexibility in the handling of low to high viscosity biomaterials.
