Fiber implementation in 3D printing

Students: Jeppe Børsting (2018) and Matias Rasmussen (2017)

CLIP (Continuous Liquid Interface Production) revolutionizes 3D printing as an industrial manufacturing process. CLIP makes it possible to make products up to 100x the speed of conventional DLS or SLA printers, and features isentropic material properties in the object comparable to those of injection molding.

However, printing in fiber materials, such as carbon fiber, is still out of reach in this process or any other process using UV lights for curing the material. Fiber materials are used in a wide range of production lines of anything between shoes and cars.

This project investigates the possibilities of implementing fiber materials into the CLIP process. The goal is to build a printer that can print simple geometries and then experimentally implement fiber materials into a wide range of resins and geometries. The experiments will validated by analyzing the microstructure and the mechanical properties of the printed objects.

Continuous liquid interface production of 3D objects (CLIP) enables fast print speeds and layerless part construction. The figure shows the schematic of a CLIP printer where the part (here a gyroid) is produced continuously by simultaneously elevating the build support plate while changing the 2D cross-sectional UV images from the imaging unit. The oxygen-permeable window creates a dead zone (persistent liquid interface) between the elevating part and the window.
