Abstract

Fused Deposition Modeling (FDM) has become popular among Additive Manufacturing technologies due to its speed, geometric scalability, and low cost; however, the primitive nature of the FDM build surface fundamentally limits the utility of FDM in terms of reliability, autonomy, and material selection. Currently, FDM relies on adhesive forces between the first layer of a print and the build surface; depending on the materials involved, this adhesive bond may or may not be reliable. Thermal contraction between the build plate and build materials can break that bond, which causes warpage and delamination of the part from the build surface and subsequent failure of the part. Furthermore, with each print, the user must use tools or manual maneuvering to separate the printed part from the build surface as well as retexture or replace the used build surface. In this paper, we present a novel build platform that allows for a mechanical bond between the print and build surface by using dovetail-shaped features. The first layer of the print flows into the features and becomes mechanically captivated by the build platform. Once the print is completed, the platform is rolled or flexed open to release the part from the mechanical bond. Thismore »« less

Highly Recyclable, Mechanically Isotropic and Healable 3D-Printed Elastomers via Polyurea Vitrimers

Journal Article Niu, Wei ; Zhang, Zhen ; Chen, Qiyi ; ... - ACS Materials Letters

Delamination of three-dimensional (3D) printed polymer materials by fused deposition modeling (FDM) is a long-standing challenge in additive manufacturing (AM). With numerous efforts devoted to modification of commercially available thermoplastic FDM filaments, developing printing polymeric materials with new chemical design that could intrinsically improve interlayer adhesion, especially combined with other benefits, is in high demand. Herein, we developed a polyurea vitrimer with heat-driven malleability, which is printed to different 3D geometries using FDM. Significantly improved interlayer adhesion was observed by post-annealing the printed samples close to its topology-freezing transition temperature upon which fast associative dynamic covalent bonds exchange reaction occurs.more »« less

Fabrication of Conductive Paths on a Fused Deposition Modeling Substrate using Inkjet Deposition

Journal Article Zhou, Wenchao ; List, III, Frederick Alyious ; Duty, Chad E. ; ... - Rapid Prototyping Journal

Inkjet deposition is one of the most attractive fabrication techniques for producing cost efficient and lightweight electronic devices on various substrates with low environmental impact. Fused Deposition Modeling (FDM) is one of the most used and reliable additive manufacturing processes by extrusion of wire-shaped thermoplastic materials, which provides an opportunity for embedding printed electronics into mechanical structures during the building process and enables the design of compact smart structures that can sense and adapt to their own state and the environment. This paper represents one of the first explorations of integrating inkjet deposition of silver nanoparticle inks with the FDMmore »« less

Infrared Preheating to Enhance Interlayer Strength of Components Printed on the Big Area Additive Manufacturing (BAAM) System

Conference Kishore, Vidya ; Ajinjeru, Christine ; Duty, Chad E ; ...

The Big Area Additive Manufacturing (BAAM) system has the capacity to print structures on the order of several meters at a rate exceeding 50 kg/h, thereby having the potential to significantly impact the production of components in automotive, aerospace and energy sectors. However, a primary issue that limits the functional use of such parts is mechanical anisotropy. The strength of printed parts across successive layers in the build direction (z-direction) is significantly lower than the corresponding in-plane strength (x-y directions). This is largely due to poor bonding between the printed layers as the lower layers cool below the glass transitionmore »« less
An innovative digital image correlation technique for in-situ process monitoring of composite structures in large scale additive manufacturing

Journal Article Spencer, Ryan ; Hassen, Ahmed Arabi ; Baba, Justin ; ... - Composite Structures

As additive manufacturing (AM) continues to develop and become a standardized manufacturing method, there will be a continued need to provide in-situ monitoring during the manufacturing of polymer composite printed components. Thermal residual stress is a primary cause of failures such as interlayer disbonds or delamination, micro cracking, and dimensional instability, which can occur during or after the build. Here, we report a novel digital image correlation (DIC) adaptation to monitor thermal residual stresses during the entire print process for large-scale AM. In this work, DIC has been investigated (a) by the natural speckle produced by the polymer surface formore »« less

Effect of surface treatment of microfiberlated cellulose fibers on biocomposite properties and additive manufacturing process

Conference Tekinalp, Halil ; Ker, Darby ; Benson, Bowie J. ; ...

Polymer additive manufacturing (AM) is a rapidly growing technology and it is transitioning to become an advanced manufacturing technique with the introduction of fiberlar reinforcing materials such as carbon and glass fibers into polymer feedstock. As a result of increasing environmental and long-term sustainability concerns, there is an increasing interest in using bio-derived cellulose fibers to reinforce composites instead of carbon and glass fibers. Melt extrusion/fused filament fabrication method is the most commonly used polymer AM technique which enables direct digital manufacturing of parts with complex geometry with a controlled anisotropic distribution of reinforcing phase. However, there are multiple factorsmore »« less
