Support material and applications thereof

摘要

In one aspect, support materials operable for use in 3D printing systems are described herein. In some embodiments, a support material comprises a wax component comprising at least one ethoxylated fatty alcohol and a viscosity modifying agent, wherein the support material is water dispersible. In some embodiments, the wax component comprises a mixture of at least one fatty alcohol and at least one ethoxylated fatty alcohol.

主权项

1. A support material for use in a three-dimensional printing system comprising:
a wax component comprising at least one ethoxylated fatty alcohol; a viscosity modifying component; and a phase change agent operable to accelerate the freezing of the support material when the support material is deposited in the three-dimensional printing system, wherein the phase change agent comprises a urethane wax that freezes or solidifies over a range of 1° C. to 3° C., and wherein the support material is water dispersible following deposition of the support material in the three-dimensional printing system.
