Curing Characteristics of Photopolymer Resin With Dispersed Glass Microspheres in Vat Polymerization 3D Printing
… resin determine the relationship between the vat polymerization (VP) process parameters and the layer thickness, geometric accuracy, and surface quality of the 3D printed specimen. Dispersing filler material into the photopolymer resin changes its curing characteristics because the filler …

Method for Photopolymerization 3D Printing of Recyclable Thermoplastic Polymers
… used in additive manufacturing (AM), such as vat polymerization, yield non-recyclable thermoset polymers, which pose sustainability issues at scale. This thesis studies a method for photopolymerization 3D printing of the common polymers polyacrylonitrile (PAN) and polymethyl methacrylate …

Fabrication and Characterization of Carbon Nanocomposite Photopolymers via Projection Stereolithography
Projection Stereolithography (PSL) is an Additive Manufacturing process that digitally patterns light to selectively expose and layer photopolymer into three dimensional objects. Nanomaterials within the photopolymer are therefore embedded inside fabricated objects. Adding varying concentrations of …

Design and Fabrication of a Mask Projection Microstereolithography System for the Characterization and Processing of Novel Photopolymer Resins
The goal of this work was to design and build a mask projection microstereolithography (MPμSL) 3D printing system to characterize, process, and quantify the performance of novel photopolymers. MPμSL is an Additive Manufacturing process that uses DLP technology to digitally pattern UV light and …

Rheology of Filled and Unfilled Polyurethanes for Reactive Extrusion-Based Applications
… laser sintering (SLS) of polymeric powders, vat polymerization (VP) of low viscosity photocurable resins, and material extrusion (MatEx) of thermoplastic or high viscosity composite materials. Because of its ability to reduce material waste while printing complex geometries, AM has the …
