it is printed layer by layer (the process in Figure 2b is replaced by that in is replaced by that in Figure 2c) with various forms of feedstock, i.e., granule, bar andfilament, depending on the printer. After printing, the subsequent debinding and sinteringsteps (Figure 2d,e) may be slightly different from the MIM process due to the differences incompositions of binders and the metal powder fraction (usually named “solid loading”),metal powder size and its distribution. The shrinkage of the sintered metal MEX part isgenerally higher than for MIM parts because the metal MEX feedstock usually has higherbinder content (lower solid loading) than MIM so that the metal MEX feedstock is printableand can be easily handled. Therefore, dimensions of the CAD model need to be carefullycompensated to acquire the required dimension after sintering. The sintered density andmechanical properties of the metal MEX part are theoretically lower than those of MIMdue to the voids between deposited paths generated during printing [8]. Thereby, the printstrategy, which can generate not only such voids but also deflection and incomplete weldin polymer 3D-print parts [128–130], needs to be carefully controlled for metal MEX beforeprogressing to the debinding and sintering
