Abstract
The present disclosure includes a three-dimensional printing kit having a fusing agent with from about 75 wt % to about 99 wt % water, and from about 0.1 wt % to about 15 wt % radiation absorber. The three-dimensional printing kit can further include a polymeric build material including polyamide-12 particles, and a liquid oil comprising from about 50 wt % to 100 wt % of a long-chain molecule having a carbon chain of about C12 to about C100.
Claims13
A three-dimensional printing kit comprising:
- a fusing agent comprising:
- from about 75 wt % to about 99 wt % water, and
- from about 0.1 wt % to about 15 wt % radiation absorber;
- a polymeric build material including polyimide-12 particles;
- and
- a liquid oil comprising from about 50 wt % to 100 wt % of a long-chain molecule having a carbon chain of about C12 to about C100.
A three-dimensional printed object, comprising:
- a polymeric body including fused polyamide-12 particles having radiation absorber embedded as particles among the fused polyamide-12 particles;
- and
- a liquid oil soaked into a surface of the polymeric body, wherein the liquid oil comprises a long-chain molecule having a carbon chain of about C12 to about C100,
- wherein three-dimensional printed object exhibits a percent strain at break that is more than twice that of a control three-dimensional printed object prepared identically but without soaking in the liquid oil,
A method of enhancing ductility of a three-dimensional printed object comprising soaking a three-dimensional printed object in a liquid oil at a temperature from about 0° C. to about 150° C. for a period of time of about 4 hours to about 1 month, wherein the liquid oil comprises a long-chain molecule having a carbon chain of about C12 to about C100, wherein the three-dimensional printed object comprises fused polyamide-12 particles having radiation absorber embedded as particles among the fused polyimide-12 particles.
