Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a system includes a plurality of containers configured to receive a plurality of additively manufactured object having excess material thereon. The system can include a rotor having a central shaft and a plurality of arms, each arm having a first end and a second end opposite the first end. The first end of each arm can be coupled to the central shaft and a second end of each arm can be coupled to a respective container of the plurality of containers. The system can also include an actuator configured to spin the rotor so as to remove the excess material from the plurality of additively manufactured objects. The system can further include at least one heat source carried on the rotor to heat the excess material to decrease a viscosity thereof.

Abstract: This disclosure provides polymeric materials comprising polymer crystals, methods and resins for making the same, and objects and appliances made from said polymeric materials. Polymeric materials having polymer crystals provide favorable properties, such as enhanced durability and rigidity. This disclosure also provides polymeric materials comprising a crystalline phase comprising at least one polymer crystal, as well as an amorphous phase comprising at least one amorphous polymer. The crystalline phase can confer rigidity to the polymeric material, while the amorphous phase can confer elasticity and flexibility.
