“…Before deposition, the substrate surface was sandblasted to eliminate any surface contamination. The experiment was performed using EWM 25 micro plasma arc welding as a heat source, connected to a 3D printer [22], and operated automatically by the Mach3 controller. The use of an on-off switch to automatically control the wire feed system in direct sync with the arc welding and motion systems.…”

High deposition rate with minimal heat input is one of the primary emphasis in wire arc additive manufacturing. This study aims to determine the optimal input parameters of micro plasma welding for single-layer deposition. The stability of a single layer is crucial as it serves as the foundation to the multi-layers deposition in producing 3D additively manufactured structure. The study focuses on wire feeding speed, welding speed, and pulse and their interaction between the input and response variables. Based on the study, the regression equation between the three key parameters and the response using the Box-Behnken Design response surface methodology was proposed. The outcome demonstrates that the optimized sample deposition produces a smooth surface appearance with no apparent defects. additive manufacturing 3D printing wire arc additive manufacturing micro plasma arc welding response surface methodology

“…Among this technique, WAAM based GMAW is highly prospective and can produce big-scale components with relative high deposition rate energy performance [11]. The GMAW-WAAM process coaxially integrated the filler wire with the welding torch and provided a quickly produced path [12]. However, the crucial issue is the irregular shapes of the accumulated bead give a significant impact on bead geometry along the welding routes from beginning to end.…”

The hybrid wire arc additive manufacturing (H-WAAM) process is one of the prominent methods for realizing large near-net-shaped metallic objects. In this process, a CAD model of the component is sliced into a set of 2D contours followed by the generation of toolpaths. An arc welding torch then follows these toolpaths for adding material over a substrate to realize the near-net shape of the object. These near-net-shaped objects are then followed by a machining operation to convert them into a fully functional part. It is always anticipated that the near-net shape of an object is produced quickly and upholds a high geometrical accuracy. Conventionally, the deposition rate is increased to reduce the build time but with a compromisation in the geometrical accuracy and material integrity. Therefore, in this work, the authors have investigated three substrate utilization methods, viz., (i) reusable substrate, (ii) embedded substrate, and (iii) integrated substrate to achieve the same goal. The build strategies for these three substrate utilization methods are illustrated through several examples. Also, a case study was performed for fabricating an impeller-like structure through a 3-axis H-WAAM setup. It has been observed that the embedded substrate method exhibits superior geometrical accuracy and takes less time to build the part as compared to other methods. A maximum of 64.34% of the material and 89.17% of build time is saved by adopting proposed build strategies compared with the traditional subtractive process.

A Fused Filament Fabrication (FFF) 3D-printer was designed, for fabrication by using in part locally sourced materials. The printer design was based on the Replicating Rapid Prototyper (RepRap) open source. The print volume of the printer is 200mm × 200mm × 300mm and it uses the Melzi V2 printer control board, coupled with the Repetier-Host firmware. The designed 3D-printer consists of galvanized steel frame, stainless steel threaded rods and wooded supports. The Finite Element Method (FEM) analysis was carried out on critical supporting components. The results obtained for the stresses are below the yield strength of the materials and the displacements are within acceptable limits, for high precision machines. The total power required by the 3D-printer was evaluated to be 197.93 W and it utilizes two thermoplastic materials namely; the Polylactic Acid (PLA) and the Acrylonitrile Butadiene Styrene (ABS).
