Abstract

Implementations described herein are directed to forming objects including one or more layers of a polymeric material that include a magnetic material. The objects can be produced by forming one or more first layers that include a first polymeric material. The one or more first layers can be free of a magnetic material. Additionally, the object can be produced by forming one or more second layers that include a second polymeric material having a magnetic material. For example, the one or more second layers can include a polymeric material embedded with magnetic particles. The one or more first layers and the one or more second layers can be formed by extruding the first polymeric material and the second polymeric material onto a substrate according to a pattern. A magnetizing device can be used to magnetize the magnetic material included in the one or more second layers.
