However, freeform fabrication of thermoset polymers remains a technical challenge. This thesis combines 3D printing with frontal polymerization (FP) — a method to rapidly cure resin — for curing filaments in tandem with the printing process. A partially cured dicyclopentadiene (DCPD) resin was developed into a printing ink. Critical rheological characteristics were identified, and DCPD inks of varying incubation times were screened to find the most suitable properties. Results of the rheological study indicate that 90 minutes of incubation time resulted in optimum print behavior. Problems associated with FP were effectively tackled through temperature control across the printing setup. In situ infrared images showed an exothermic reaction front propagating during the print process, giving evidence of in situ polymerization. The optimized technique produced one-dimensional, two-dimensional and 3D freeform prints with excellent fidelity. A self-equilibrating behavior was identified in the reaction front, such that the front autonomously tune its speed to the programmed print speed. This phenomenon autonomously controls the viscoelastic bridge length, Lb, and inevitably curbs deformations to achieve high print fidelity.","Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01","The student, Jia En Aw, accepted the attached license on 2019-04-26 at 14:07.","The student, Jia En Aw, submitted this Thesis for approval on 2019-04-26 at 14:16.","This Thesis was approved for publication on 2019-04-26 at 14:46.","DSpace SAF Submission Ingestion Package generated from Vireo submission #13952 on 2019-08-22 at 16:24:04","Embargo set by: Seth Robbins for item 112399 Lift date: 2021-08-23T20:48:32Z Reason: Author requested closed access (OA after 2yrs) in Vireo ETD system","Limited Restriction Lifted for Item 112399 on 2021-08-24T09:15:35Z."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Simultaneous three-dimensional printing and frontal polymerization of dicyclopentadiene resin"]}]}],"canonical_facts":{"dc:contributor":["Sottos, Nancy R.","Geubelle, Philippe H."],"dc:creator":["Aw, Jia En"],"dc:date":["2019-08-23T20:48:28Z","2021-08-24T09:15:35Z","2019-04-26","2019-05"],"dc:description":["Made available in DSpace on 2019-08-23T20:48:28Z (GMT).
