A computer module includes a housing having a cover defining a condenser chamber, and a heat-absorbing unit having at least one cavity body adapted to contact a heat source, and a working fluid received in the cavity body. During the creation of an electronic design of a product intended for subsequent printing, user-provided location information is received by a server computer and used to generate a user map suitable for high quality printing. An at least one layer of a second material is deposited over the atomically sharp feature.
