Fig. 4. First lab-scale print: (a) printing in progress for hollow cylindrical geometry with the mixture of short open time at a constant accelerator dosage, (b) layer breakage during the printing of upper half, and (c) layer shortening predominantly during the printing of upper half

Fig. 5. Second lab-scale print: (a) printing of final layer before collapse for hollow cylindrical geometry with a mixture of short open time and after continuous accelerator dosage adjustment, and (b) inconsistencies in the layer printing

Fig. 6. Third lab-scale print: (a) printing in progress for hollow square geometry with a mixture of large open time, (b) uniform layer printing without visible surface cracking, and (c) printing without layer shortening and breaking
