M8KR™ by MakerHero

Benchmarking

When it comes to perfect prints, torture calibration tests are a maker's best friend. Torture test models are designed to put the capabilities of your 3D printer to the test.

M8KR™ is not a pressure test, but rather a benchmarking model. This everyday hero prints nicely in fine-tuned enviroments and offers visual inspections such as bridge span, overhangs quality, dimensional accuracy, surface smoothness and layer extrusion. It includes small embossed and debossed details, fillets, chamfers, some extreme overhangs, bridging, smooth curves, and more.

SURFACE FINISH The Cape is the best place to check surface quality, M8KR™ is triangulated at a very high resolution which yields smooth surfaces. The maximum deviation from the original file is set to 0.001 mm.
TOP LAYERS The visor's top surface is horizontal, planar, and parallel to the bottom plane. Excellent for visually identifying extrusion issues.
OVERHANGS The bottom of the visor features a 65º overhanging straight surface, which is challenging to 3D-print.
RESOLUTION The shield's letters are less than 3 mm tall, with a protrusion of only 0.2 mm. Excellent for checking definition and detecting ghosting.
FIRST LAYER The legs are perfectly round, making first-layer squashing simple to notice.
BRIDGING The cape's bottom provides multiple features for testing different bridge spans.
ACCURACY The foot sole contains an 8mm HEX hole for checking dimensional accuracy; when printed at 100% scale, it fits an M5 nut and at 70% scale, it fits an M3 nut. It should fit with out excessive force and stay in place.
STRINGING M8KR™ is holding a filament coil in his left hand, this section helps identify definition of small perimeters and stringing/oozing.
Tolerance M8KR™ is holding a resin bottle in his right hand, which features a 45º cylindrical opening for testing tolerances. Made to fit a piece of 1.75mm filament. M8KR™ likes to keep a sample of the filament that was used.
