Description	The preparation of ceramic microchannel structures from powder based material is a time consuming, expensive or inﬂexible process. This work demonstrates microtemplating – a new reliable and economical fabrication method for preparing ceramic alumina self-supporting microchannels with diameters from 10 to 1000 mm. The basis for this method is the controlled dip-coating of a sacriﬁcial polymeric ﬁber template with suspensions containing sinterable particles. Subsequent sintering results in self-supporting ceramic microchannels. Thermal behavior of a microtemplate is critical for achieving self-supporting microchannels. We used polyamide, keratin, para-aramide, polypropylene, and polyimide ﬁbers to set models of microtemplate thermal behavior. We found that the negative inﬂuence of thermal expansion and gas production could be eliminated by microtemplates with hollow and porous internal structure. Furthermore we show ﬂexibility of the green stage procedure on an alumina microﬂuidic loop and a multichannel system with gradient porosity. The microtemplating is demonstrated to be an inexpensive and ﬂexible process.
