Three-dimensional scaffolds to facilitate engineered tissue growth are described herein. An exemplary scaffold comprises a first capillary element, a second capillary element, and a connective element that spans a distance between the first capillary element and the second capillary element, connecting the capillary elements. Tissues can be grown within the scaffold such that the tissues have highly vascularized structures with many capillaries running throughout. The scaffolds can be fabricated by selective electrochemical etching of a semiconductor element. The electrochemical etching can be controlled by way of a laser configured to stimulate multiphoton absorption in the semiconductor.

A method of making a medical device includes forming a precursor medical device using additive manufacturing. The precursor medical device includes a first portion, a second portion, a first connector, and a second connector. The first connector connects the first portion to the second portion and is configured to remain. The second connector connects the first portion to the second portion and are configured to be removed. The second connector is formed such that the second connector is less ductile than the first portion, the second portion, and the first connector. The precursor medical device is processed to remove the second connector without adversely affecting the first portion, the second portion, and the first connector.
