Abstract
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.
Claims13
A support material for use in a three-dimensional printing system comprising:
- a wax component comprising at least one ethoxylated fatty alcohol;
- and
- a viscosity modifying component comprising at least one lactone, wherein the support material is water dispersible and wherein the lactone is at least partially polymerized.
A support material for use in a three-dimensional printing system comprising:
- a wax component comprising at least one ethoxylated fatty alcohol;
- and
- a viscosity modifying component comprising at least one lactone, wherein the support material is water dispersible and wherein the at least one lactone comprises α-acetolactone, β-propiolactone, γ-butyrolactone, δ-valerolactone or ε-caprolactone or mixtures thereof.
A support material for use in a three-dimensional printing system comprising:
- a wax component comprising a plurality of ethoxylated fatty alcohols;
- and
- a viscosity modifying component, wherein the support material is water dispersible and wherein the plurality of ethoxylated fatty alcohols comprise one or more ethoxylated fatty alcohols of the formula CH3—(CH2)m—(O—CH2—CH2—)n—OH, wherein n is an integer from 2 to 100 and m is an integer from 10 to 20 , and a sorbitan monooctadecanoate poly(oxy-1,2-ethanediyl).
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 comprising one or more polyurethane waxes,
- wherein the support material is water dispersible.
