Inconel 718 Additive Manufacturing continues to be one of the major advancements in industries like aerospace and energy. This is mostly because of the alloy’s unique heat resistance and strength. Unlike typical machining, Inconel 718 Additive Manufacturing has the advantage of building parts layer by layer. This capability allows it to manufacture parts with highly intricate designs and geometries. Although, the highly intricate designs and geometries does have some unique challenges imposed during the Inconel 718 Additive Manufacturing that would include the decreased product quality, decreased efficiency during the production, and problems with cost management. The more industries start using the additive Inconel 718 to manufacture high quality components, the better untapped challenges should be understood to solve. This blog looks to resolve the challenges in Inconel 718 Additive Manufacturing.
One of the challenges of Inconel 718 Additive Manufacturing is the characteristics of the alloy itself. Inconel 718 has high thermal conductivity which leads to the development of brittle internal structures. These internal s defects include cracks, porosity, and brittle phases. The quality of the Inconel 718 powder directly influences the additive manufacturing outcome, along with the powder morphology. Factors like irregular and contaminated powder are considered to be one of the major causes of layer bonding issues.
To address the issues, it is recommended that manufacturers utilize high purity Inconel 718 powder, with a specific particle size distribution between 15 and 45 micrometers. Reducing thermal gradients and the possibility of cracking is also assisted by preheating the build platform. Solution annealing and aging, on the other hand, improve the mechanical properties of the part post processing and after brittle phase removal, assist in bypassing the brittle phase problem entirely in Inconel 718 Additive Manufacturing.
In the case of Inconel 718 Additive Manufacturing, process parameters pose another major challenge. Laser power, scan speed, layer height, and hatch spacing are all parameters that need specific calibration, and even minor inaccuracies in these parameters can lead to major defects. For instance, the portion of the laser that is too powerful might cause over melting, and the speed of the scan being too low can lead to incomplete fusion. A possible solution to this is the use of intelligent systems that offer simulation and variable testing before the actual production for the manufacturers. As is the case in modern Inconel 718 Additive Manufacturing, the real time monitoring tools of other advanced manufacturing systems allow for parameter tracking and define a ratio of precision for the layers. This quasi-automated adaptive control of layers is facilitated by the real time analysis of the parameters and the pre-set control of the parameters by the operators. The Inconel 718 Additive Manufacturing process can also be improved with the precision of small scaled designed part trials that define specific parameters.
One of the primary challenges in Inconel 718 Additive Manufacturing is ensuring the quality of the product. While the production of Additive Manufactured parts is taking place, internal defects, including microcracks and porosity, are exceedingly difficult to identify. Quality inspection techniques are merely unsightly for intricate Inconel 718 Additive Manufactured parts. To counter this, the process should incorporate more sophisticated NDT techniques like CT and ultra-sonic scanning techniques. These techniques detect internal flaws and ensure the part meets the required standards. In addition, implementing a complete data traceability system aids in tracking the Inconel 718 Additive Manufacturing process. This system is very process oriented, and assists in tracking and tracing the process data and inspection results. This preventive measure will ensure that defects are not replicated in future Inconel 718 Additive Manufacturing processes.
Post-processing in Inconel 718 Additive Manufacturing is very critical and it is to be understood, it comes with challenges. It is to be understood that parts are to be accurately post-processed to remove support structures, surface finishing, and heat treatment. Removing support structures from complex Inconel 718 parts is more difficult and time-consuming in addition to increasing the possibility of damaging the part.
Support structures can be designed with cut features so that streamlining post processing will be easier. For instance, support structures can be designed with thin “pins” that can be easily removed. Inconel 718 Additive Manufacturing surfaces can be post processed made to be uniform with automated systems like robotic grinding. Customized post processing heat treatment designs reduce Inconel 718 Additive Manufacturing residual stress, improve mechanical properties, and avoid adding heat.
The benefits of Inconel 718 Additive Manufacturing in multi precision industries are immense, and the challenges that these industries face are what will determine the extent of implementation. Overcoming chalenges of material purchasing by investing in quality powder, heat treatment, and refining process parameters through intelligent embedded sensing, developing NDT and traceability systems for process control layers, and automating post processing will simplify work for these industries. Future technologies that integrate strategic and automated process control will enhance processing Inconel 718 Additive Manufacturing. Lighting speed implementation of designed systems would allow these industries to perform advanced Inconel 718 Additive Manufacturing and create intricate parts. This would promote the multi precision industries in spheres like aerospace and energy.
