The Mega S delivered typical results on the whole, earning it an average score in the middle of the group. We began our print quality metric with a very common 3D printer calibration/torture test, the 3D benchy. This little tugboat is a great all-around benchmarking test, with a variety of different geometries all designed to tax filament printers. The Mega S did decently well, delivering average prints in both PLA and ABS. There was only a small amount of dropping on overhangs and the text on the bottom of the PLA version was legible but the hull had a rough finish with some weird indentations. The text on the ABS version was also essentially unreadable. The bridging test. Credit: Jason Peters. Next, we looked at how each printer handled bridges (unsupported features) and small details, with our bridging and Eiffel Tower tests. The Mega S gave far from a good performance with these two prints, with both ABS versions failing completely. The PLA version of the Eiffel Tower did finish printing but it looked horrible in our opinion, definitely stretching a bit to call it a successful print. The PLA bridging test, with some noticeable sagging on the longer bridges and an overall lackluster print quality. Next, we scored the quality of a print-in-place articulated poseable elephant, an overhanging geometry test, and a dimensional accuracy test. The performance of the Mega S did improve a bit with these three prints, delivering average or above results with the elephant and the overhangs. The PLA and ABS elephants both articulated freely, but the print quality is overall a bit rough, with plenty of deformities and defects. It was a similar story with the overhangs, with all but the steepest overhangs actually printing well but the overall quality just seemed to be lacking compared to the top-tier printers.

Unfortunately, both of the openings were a little on the larger side, with plenty of gaps around the coin. The Anycubic Mega S struggled with the next model, another single-piece articulated model. This printer failed with both the PLA and ABS platform jacks. The ABS wouldn't print successfully and the PLA version repeatedly broke whenever we tried to actuate it. Performance did rebound a bit with the wireframe cube, with this printer only having minimal sagging and a few strings on both PLA and ABS prints. The low-poly figures. Credit: Jason Peters. This printer did continue to do well with the pair of low-poly figures, with fairly clean surfaces and smooth overhangs, though the ABS version of the smaller model did have a rough surface finish. It also did well with the single-shell spiral vase in both types of plastic, though again had the less than amazing surface finish.
