Abstract: The research lays the foundation for the fabrication of 3D electronic components using a hybrid additive manufacturing technology.
Additive manufacturing of conductive traces can eliminate several post-processing operations in traditional manufacturing methods such as photolithography, tape casting, and screen printing. In this research, the conductive traces were fabricated using carbon slurry and nickel ink using microextrusion and pico-jet units, respectively. The deposited traces were cured using two sintering mechanisms which include furnace heating and laser irradiation. The effect of curing mechanism on the conductance of deposited traces was evaluated.

Abstract: Recent advances in Fused Filament Fabrication, including 5-axis printing and additive patching/remanufacturing, involve additive manufacturing atop a previously manufactured polymer substrate. The success of these technologies depends upon the bond strength between the substrate and the newly added geometry. This research investigated the effect of three factors on bond strength: surface roughness of the substrate, layer thickness of the added geometry, and the relative raster angle between the two. The results indicate that bond strength can be increased by up to 27% with the proper choice of parameters.
This research indicates that manufacturers have to intelligently select process parameters for the production of both the substrate and the added geometry.

Abstract: Additive manufacturing alleviates the accessibility constraints in manufacturability, but its limited building direction, undesirable surface finish and constrained production environment significantly hinder the capability of making cost-effectively functional parts. The paper presents a new concept of using air levitation in Additive Manufacturing with the intention of overcoming the process-imposed deposition and building directions. The paper focuses on the initial development of air suspension based additive manufacturing and seeks to minimize oscillation in the levitation. The research employs a Design-of-Experiment approach and intends to identify the optimal operation parameters of air nozzles such that the fluctuation of the levitated spherical particle is minimized.
Abstract:
Nanoparticle are now used in 3D printing polymers. The formulation of high quality nanoparticle inks for micro 3D printing is complicated by factors including rapid oxidation and particle agglomeration. Reactive metal inks are particle-free solutions which can be printed and subsequently converted to their metallic state by a thermally induced chemical reaction. These inks show promise in overcoming many of the problems associated with nanoparticle inks.
In this research, copper, nickel, and silver reactive inks have been formulated with the appropriate rheological properties for inkjet printing. The inks can be sintered at very high speed via pulsed photonic curing. Designed experiments involving ink composition, printing parameters, and sintering parameters were conducted to produce the ideal material properties for each application.
Abstract:
Engineered lattice structures have attracted a great deal of interest due to their potential to reduce weight in vehicles. The additive manufacturing of polymer-carbon fiber composite lattice structures is ideal from a strength-to-weight perspective,
This paper describes an Axial Lattice Extrusion (ALE) technique in which the extrusion toolpath includes simultaneous motion in all three principle axes (i.e. extrusion head motion is not limited to the X-Y plane and can be moved “uphill” to produce continuous vertical struts without any layering). This technique allows carbon fibers to be oriented parallel to the strut axes for maximum bending stiffness. The paper describes process planning considerations to avoid collision of the deposition head with previously deposited material, and it includes consideration of process parameters needed to avoid unwanted sagging of unsupported material. Specifically, material selection, extrusion temperature, print velocity, and the use of chilled cooling gas are all discussed.

Abstract
Hybrid: Combining additive manufacturing and subtractive manufacturing to reduce cost
In hybrid manufacturing, Additive Manufacturing (AM) or 3D Printing is combinded with a subtractive process of CNC milling, typically in the same envelope. It provides improvements in surface finish and accuracy over AM processes alone, and also reduces overall production costs by producing the beginning portion of a part through a subtractive process. The bulk material is typically less expensive compared to power and production rates can be higher for subtractive processes like CNC milling and turning. In the research, the problem of determining the appropriate starting stock is explored and a process planning tool is developed to support decision making. Bulk material costs, cutting processes parameters, powder stock costs, AM process parameters, geometry and tooling access, among other parameters, are considered in the model. Several case studies are presented.

Abstract:
A heterogeneous object (HO) is referred to as a solid component consisting of two or more material primitives distributed either continuously or discontinuously within an object. HOs are commonly divided into two categories: the first type has distinct material domains separating the different materials and the second one called functionally graded materials (FGMs), has the continuously variation of material composition that produces gradient in material properties. Modeling and manufacturing of HO has come to attention recently due the advent of additive manufacturing technology that makes it possible to build such parts.
These processes require vector based tool paths to allow for the proper positioning of the deposition head. This paper presents a concept for automatically generating the toolpath for any type of HO considering the material composition changes that are required on each layer. The tool path generation takes into account the physical limitations of the machine associated with powder delivery and ability to continually grade the materials.
Abstract:
Cold spray uses pressurized gas as a carrying media of metal particles in additive manufacturing. The mixture of gas and particles pass through a converging-diverging (de-Laval) nozzle where the gas expands and accelerates to supersonic speeds. The nozzle design is considered as one of the most critical issues in the system and it is considerably affect the quality of the finished parts. In this paper, an optimized nozzle design is proposed, computational fluid dynamics simulation of the gas flow is analyzed and manufacturing processes of the assembly is discussed.
Abstract:
This paper first discusses literature of part repairing using additive based HM process. Then, a new feature analyzing methodology is discussed illustrating the interaction of additive and subtractive manufacturing features of both existing and final parts to analyze feature interaction for HM. All the possible combinations of feature interaction are considered under this analysis. Further, additive nozzle cannot reach vertical walls in the process of filling an existing manufacturing feature due to nozzle angle and under this paper, an analysis of additive nozzle accessibility is also discussed to avoid voids in material adding process. Finally, advantaged and limitations of the analysis are discussed with directions for future.

Abstract:
Coolant is used in the Hybrid Directed Energy Deposition (HDED) process. In instances where coolant is used during CNC cutting followed by material addition, there is the potential for contamination if residual coolant is present on the new deposition surface. In this work, evaluation of the effects of residual coolant on mechanical strength and the impact of two procedures commonly used to remove this residual coolant is done. Samples are prepared using processes aiming to mitigate the effects of coolant including the use of compressed air as well as diffuse laser energy for oxidizing organic residue. Results of Ultimate Tensile Strength (UTS) and recommendations for processing are presented, along with comparisons of adding a post process step of hot isostatic pressing (HIP).

Abstract:
AM productivity
According to the design for assembly (DFA) concept, design features should be integrated into a few physical parts to reduce design complexity. However, building up a single product can have some negative effects on the AM productivity by increasing buildup time and cost. In this paper, a design framework using the assembly concept is proposed with the aim of letting the AM productivity reach an allowable level. The design framework is developed based on an Axiomatic Design (AD) approach, where AM productivity elements including buildup time, assembly time and the amount of support are considered as non-functional requirements (nFRs). The AM productivity is assessed by the Information Axiom to choose the best design. The proposed design framework can help engineers design and evaluate AM products.
