This article presents the results of the binder jetting technology application for the silicon nitride ceramics production. A modified version of the Plan-B 3D printer with an epoxy-based binder was used for silicon green bodies preforming. Silicon powder was pre-coated with epoxy resin, and the curing agent was added during 3-D printing of green bodies using a standard cartridge. Curing and removal of organics was carried out during the high-temperature vacuum drying of the printed preforms. Reaction-bonded silicon nitride was obtained by using pressureless sintering. An additional compaction of green bodies is proposed to reduce the porosity of green bodies and sintered ceramics. It is shown that the proposed methods allows to improve the mechanical properties of sintered specimens.

“…There is a growing awareness in the engineering research community of the potential of solid freeform fabrication to greatly expand the space of manufacturable devices by enabling greater geometric freedom in designs and controlled spatial heterogeneity in material composition (Fuller et al, 2002;Colvin, 2004;Bak, 2003;Dybala et al, 2002;Liu et al, 2004;Stampfl et al, 2002;Li et al, 2000;Cooper et al, 1999;Ouyang et al, 2002;Smurov and Yakovlev, 2004;Noecker and Dupont, 2002;Duty et al, 1999;Domack and Baughman, 2005). In light of this potential, we are developing a multiple-material freeform fabrication system, and a library of mutually compatible functional components which can be produced together to create fully integrated, active, electromechanical devices.…”

Purpose-To seek to produce low-voltage, soft mechanical actuators entirely via freeform fabrication as part of a larger effort to freeform fabricate complete electromechanical devices with lifelike and/or biocompatible geometry and function. Design/methodology/approach-The authors selected ionomeric polymer-metal composite (IPMC) actuators from the literature and the authors' own preliminary experiments as most promising for freeform fabrication. The authors performed material formulation and manual device fabrication experiments to arrive at materials which are amenable to robotic deposition and developed an SFF process which allows the production of complete IPMC actuators and their fabrication substrate integrated within other freeform fabricated devices. The authors freeform fabricated simple IPMC's, explored some materials/performance interactions, and preliminarily characterized these devices in comparison to devices produced by non-SFF methods. Findings-Freeform fabricated IPMC actuators operate continuously in air for more than 4 h and 3,000 bidirectional actuation cycles. The output stress scaled to input power is one to two orders of magnitude inferior to that of non-SFF devices. Much of this difference may be associated with processsensitive microstructure of materials. Future work will investigate this performance gap. Research limitations/implications-Device performance is sufficient to continue exploration of SFF of complete electromechanical devices, but will need improvement for broader application. The feasibility of the approach for producing devices with complex, non-planar geometry has not been demonstrated. Practical implications-This work demonstrates the feasibility of freeform fabricating IPMC devices, and lays groundwork for further development of the materials and methods. Originality/value-This work constitutes the first demonstration of complete, functional, IPMC actuators produced entirely by freeform fabrication.

Nondestructive characterization of micromachined ceramics

et al. 2005

View full text Add to dashboard Cite

The aerospace, automotive, and electronic industries are finding increasing need for components made from silicon carbide (SiC) and silicon nitride (Si 3 N 4 ). The development and use of miniaturized ceramic parts, in particular, is of significant interest in a variety of critical applications. As these application areas grow, manufacturers are being asked to find new and better solutions for machining and forming ceramic materials with microscopic precision. Recent advances in laser machining technologies are making precision micromachining of ceramics a reality. Questions regarding micromachining accuracy, residual melt region effects, and laser-induced microcracking are of critical concern during the machining process. In this activity, a variety of nondestructive inspection methods have been used to investigate the microscopic features of laser-machined ceramic components. The primary goal was to assess the micromachined areas for machining accuracy and microcracking using laser ultrasound, scanning electron microscopy, and white-light interference microscopic imaging of the machined regions.
