Abstract
Stereolithography with micron scale control of properties is described herein. In one aspect, a computer-implemented method for 3-D printing of a material can include generating a functional relation predicting one or more physical properties of the material resulting from printing parameters; algebraically or numerically solving the functional relation to generate a second functional relation predicting expected printing parameters resulting in the one or more physical properties; and printing the material via a photopolymerization printer according to the set of printing parameters determined by the second functional relation.
Claims12
A computer-implemented method for 3-dimensional (3-D) printing of a material, the method comprising:
- generating a functional relation predicting one or more physical properties of the material resulting from printing parameters, wherein the one or more physical properties of the material is selected from the group consisting of a cross link density, a swellability, a Young's modulus, a diffusivity coefficient, a shear modulus, a stiffness factor, a viscoelasticity factor, and a coefficient of friction;
- algebraically or numerically inverting the functional relation to generate a second functional relation;
- determining a set of printing parameters from the second functional relation;
- and
- printing the material having the one or more physical properties via a vat photopolymerization printer according to the set of determined printing parameters.
A non-transitory computer-readable medium including instructions executable by a processor for printing a material, the instructions comprising:
- generating a functional relation predicting one or more physical properties of the material resulting from printing parameters, wherein the one or more physical properties of the material is selected from the group consisting of a cross link density, a swellability, a Young's modulus, a diffusivity coefficient, a shear modulus, a stiffness factor, a viscoelasticity factor, and a coefficient of friction;
- algebraically or numerically inverting the functional relation to generate a second functional relation;
- determining a set of printing parameters from the second functional relation;
- and
- printing the material having the one or more physical properties via a vat photopolymerization printer according to the set of determined printing parameters.
