Description

Carbon fiber doctor blade chambers produced by BFT are light, strong and durable with incomparable performance. Designed with the intention to optimize print quality and obtain considerable waste reductions.

BFT chambers are different from other carbon fibre doctor blade chambers in three key ways:

1. The wall consists entirely of carbon fibre skins that have been securely bonded together. This means that the carbon fibre skins are not laminated together with any material other than carbon.
2. The doctor blade holder pretensioner system uses springs housed in seats incorporated entirely in the moulding of the chamber, meaning that no holes need to be cut into the structure for the pretensioner system. These seats are repeated at fixed intervals along the chamber moulding, conferring extreme stiffness to the system regardless of the length of the chamber itself and irrespective of changes in temperature.
3. The doctor blade chamber cavity is completely hollow. This is achieved by using air bags during the moulding process, which are then removed at the end of the curing process in the autoclave. Packaging Plast doctor blade chambers are made entirely of structural carbon fibre. Other doctor blade chambers have carbon fibre laminated on top of a structure of a different material so the carbon fiber is merely cosmetic.
