Study of Liquid Rubber Printing on a 3D Printer by Using a Peristaltic Pump

Abstract

The additive manufacturing (AM) process known as direct-ink writing (DIW), also known as direct-print (DP) or direct-write (DW), has great practicality in a variety of material types. In this process, it is essential for the ink formulation utilized for the DIW process to be a paste-type ink with a time-dependent shear-thinning property. Rubber has been utilized in a variety of applications however, the high pressure and temperature needed to treat natural rubber make it difficult to employ as a printable ink in the DIW process. In this study, the use and modification of processed liquid rubber which is commercially available wereinvestigated for the DIW process. The DP system used in this research includes a syringe connected to a peristaltic pump which is used as an attachment to a 3D printer having a movable horizontal plane controlled by an XYZ-stage. Since liquid rubber has a high solid content, it was utilized as a matrix in ink formulations to increase printability. While formulating rubber for 3D printingit is observed that boric acid powder can be used as an additive to make rubber a printable ink. To check the strength of the mixture a tensile test has been done on both rubber specimens. To identify a range of ideal printing settings, the effects of printing pressure and speed on 3D printability were examined. Several specimens were created using optimal printing parameters for tensile and dimensional accuracy tests. The DP technique successfully created 3D structures, and it is thought that the suggested ink formulas will be successful in 3D printing rubber applications in the future.
