Abstract
The instant invention relates to a method for changing characteristics of a plastic component, wherein a medium is introduced into the plastic component, which encompasses a porosity and wherein the medium forms a homogenous compound with the plastic component by at least partially dissolving the plastic component.
Claims18
A method comprising:
- bonding synthetic particles together to form a plastic component having a porosity;
- changing characteristics of the plastic component after the plastic component is formed by introducing a medium into the plastic component,
- wherein the medium forms a homogenous compound with said plastic component by at least partially dissolving the plastic component.
A method comprising:
- a. assembling synthetic particles into a three-dimensional plastic component using a three-dimensional printing process or a laser sintering process;
- b. controlling porosity of the three-dimensional plastic component during assembly of the synthetic particles;
- c. introducing a medium into the three-dimensional plastic component after the step of assembling is complete so that the medium at least partially dissolves the three-dimensional plastic component;
- d. solidifying an outermost layer of the plastic component by subjecting the outermost layer to UV radiation so that a geometry of the three-dimensional plastic component is not lost;
- e. rotating the three-dimensional plastic component so that shadowed areas of the three-dimensional plastic component are solidified;
- and
- f. solidifying an inner part of the three-dimensional plastic component after the outermost layer has begun solidification;
- wherein polymerization occurs between the three-dimensional plastic component and the medium forming a homogenous compound in response to the solidification.
