Publication number: 20140110879Abstract: A method of preparing a patterned micro-contact printing stamp for micro contact printing including the making of a submaster of e.g. epoxy, against which a micro-contact printing stamp from polydimethylsiloxane or other stamp forming material can be formed. The micro-contact printing stamp can then be exposed to an inking material while the micro-contact printing stamp is still against the submaster, resulting in a micro-contact printing stamp capable of making numerous impressions before the inking material is exhausted.Type: ApplicationFiled: June 27, 2012Publication date: April 24, 2014Applicant: 3M INNOVATIVE PROPERITIES COMPANYInventors: Jonathan J. O'Hare, Richard W. Greger, Mikhail L. Pekurovsky, Daniel P. Meehan

Patent number: 8668856Abstract: A method for forming a composite structure, using a mandrel that is later removed from the composite structure, involves production of a mandrel by depositing a particulate mixture, including an aggregate and a binder, into a mold and removing the mandrel from the mold. The mandrel may be treated while still in the mold by heating, curing with an agent, microwave energy, or by some combination thereof. Once finished, the mandrel can be used in manufacturing polymer and/or composite components. The mandrel can also include materials that can be easily removed from the finished composite structure by water, shakeout, chemically dissolving, or by some combination thereof.Type: GrantFiled: August 3, 2011Date of Patent: March 11, 2014Assignee: Advanced Ceramics MannufacturingInventors: Jens Rossfeldt, Matt Wallen
